Opis:
Three methods were used to assess silvicultural quality of two−year−old Scots pine (Pinus sylvestris L.). The assessment was based on measurements of biometric parameters, colonisation level of micorrhizas and electrical impedance of cambial tissues of shoots. The applicability of these methods with special reference to micorrhizal colonisation and impedance methods, which so far were not used in the assessment of the planting material, was analysed.

Opis:
In the paper the authors compare the growth of plantations established with 1−year−old container−raised small root−ball and bare−rooted pine seedlings. The planting dates were: late summer, early spring, late autumn and spring. The experiment results showed that irrespective of the type of seedlings used the growth of plantations originated from the summer and autumn planting was not inferior to those established in spring. The percentage of root−ball seedlings was higher. After two years they showed better height growth than the bare−root seedlings however the effect depended on planting date. The obtained results proved sufficient to begin experimental planting on a large commercial scale. The establishment of plantations in summer and autumn can make the seedling storage unnecessary and reduce nursery production costs.

Opis:
To test the influence of selected fertilisers and fungicides on the germination of black alder seeds and the initial phase of seedling growth, we conducted a laboratory experiment outlined in this paper. Six treatments were applied on petri dishes each containing 30 seeds. The substrate for germination was sterile filter paper wetted with an aqueous solution of either one of two fungicides, two organic fertilisers, a mineral fertiliser or distilled water (control). Fungicides and fertilisers were applied according to the manufacturers’ recommendations. In order to keep genetic variability to a minimum, seeds originated from a single tree in a seed stand located in the Chotyłów Forest District, eastern Poland. Germination and growth took place at a temperature of 23oc ± 2oC with a 14 h/10 h day/night cycle. Seeds began to germinate as early as the second day after sowing, except for the mineral fertiliser treatment, in which the first sprouting was observed on day 3. Seedling length was measured daily from the day of germination of a given seed through to day 15. Germination was found to proceed most rapidly in the control, while the largest increments in length and dry mass occurred in the control and fertiliser treatment with the so-called N1 fertiliser (solely comprising growth stimulators in the form of humic acids, chitosan and silicon). The most limited growth was observed under the influence of the F1 fungicide (active compound Thiram) as well as the organic fertiliser N2 (a mixture of mineral components and organic growth stimulators). Roots were found to develop most rapidly in the control and in the treatment with N1 (no mineral components). These are also the only two treatments in which the roots were longer than the stems after 15 days. Fertiliser N2 was found to have the most unfavourable influence on both, germination and the first phase of seedling deve- lopment. The fact that selected fertilizers and fungicides affected black alder seeds and seedlings under laboratory conditions does not mean that they will have an impact under field conditions or on other forest tree species. Therefore, this type of research will need to be conducted individually for each forest tree species.

Opis:
Taxus baccata L. is a relict plant and has a scattered distribution in the entire species range. Yew regeneration may be affected by moisture conditions and tree stand characteristics – variables which change over time and which have not been sufficiently researched to date. The present study determined the size structure of yews, causes of yew mortality, the effects of tree stand characteristics and habitat conditions on yew diameter increment at breast height, the density of yew seedlings and saplings, and the likelihood of yew seedling occurrence. The study was conducted in central Poland, on 22 permanent sampling plots. The paper presents data col- lected in 2017 with reference to previous studies on these plots from 2001 and 2007. Stand volume, basal area, number of trees, canopy cover, and type of forest site were established for the tree layer. Saplings and shrubs were counted. Finally, the parameters determined for yew seedlings included density and percentage of individuals damaged by browsing, as well as soil moisture and percentage cover of herbaceous vegetation in the nearest neighborhood. In 2017, yew density in the tree layer was 70 individuals/ha, having increased by 15 individuals/ha over 16 years. During that period, 6.4 individuals/ha died in that layer. The predominant cause of yew mortality was wind. In the period 2007–2017, the mean diameter increment at breast height was 2.2 mm/year, and indicated a weak relationship only with tree diameter at the beginning of the studied period (R2 = 0.06). In 2017, the mean density of yew saplings and seedlings was 55 individuals/ha and 1005 individuals/ha, re- spectively. Two independent variables were found to be significant in the model of yew seedling occurrence: presence of mature yews on the sampling plot and soil moisture. The condition of the studied yew population is satisfactory, especially in the less moist areas. The number of seedlings is acceptable, but more active protection should be considered due to the scarcity of yew sap- lings. This is all the more important as seed-producing mature yews tend to die as a result of exposure to strong winds and periodic local flooding.

Opis:
The goal of this paper was to prove the possibility, and determine the most important hazards of beech planting stock production under the climatic conditions of north−eastern Poland. Considered were time of sowing, soil coverings and mulch type in four operational nurseries of the State Forests over the period of four years. The use of simple nursery technological solutions in bare−root forest nurseries is sufficient for the production of quality beech planting stock, also outside the natural distribution limits of the species. The most crucial natural factors for the production of beech seedlings proved to be: spring frost, damage to seed and seedling by maggots and birds. It was estimated that before the early frost, all seedlings had produced the top bud. The autumn sowing with use of sawdust covering was found to be the most effec− tive technological solution in the sense of planting stock productivity. The spring sowings were less effi− cient because of the necessity to use properly stratified seed, a condition hardly met in the poorly equipped bare−root nurseries. The largest 1/0 seedlings (dry weight per seedling) were those originated after the autumn sowing. The smallest seedlings were grown in plots with coniferous sawdust coverings. Another finding of the study was that the use of above ground covers, allowing 40% daylight intensity had reduced the final dimensions of the one−year old beeches.

Opis:
The aim of the study was to evaluate in mycological aspect stored horseradish seedlings derived from the strict field experiment, with an application of chemical and non-chemical protection. Regardless of protection manner, the population of fungi present in horseradish seedlings was dominated by the following species: V. dahliae (14%), C. destructans (8%), E. purpurascens (7.7%), R. solani (7.3%), T. hamatum (6%). Protection improves the health status of the seedlings, and better protective effect is obtained by the application of synthetic fungicides which, compared to the control site (541), reduces the amount of fungal isolates to 266. The second stage of the study involved an evaluation of antifungal activity in vitro of 1.0; 0.5; 0.1 mm3·cm-3 juniper oil with respect to above mentioned fungi. In laboratory conditions, regardless of the concentration juniper oil strongly inhibits the linear growth and sporulation of fungi the most intensively colonizing horseradish seedlings. Mean values of colony surface growth limiting are in the range from 50.66% for V. dahliae to 90.1% for R. solani. Also, an increase in juniper oil concentration in the culture medium results in an increased inhibition of fungi sporulation. The presence of 1.0 mm3·cm-3 oil in the medium oil causes 90.4% reduction of C. destructans, and 82.1% of V. dahliae spores. A very strong fungistatic effect of juniper oil in vitro may be the basis for further research on its application in plants protection against root rots.
Celem badań była mykologiczna ocena przechowywanych sadzonek chrzanu pochodzących ze ścisłego doświadczenia polowego, w którym zastosowano ochronę chemiczną oraz niechemiczną. Niezależnie od sposobu ochrony populacja grzybów zasiedlających sadzonki chrzanu była zdominowana przez gatunki: Verticillium dahliae (14%), Cylindrocarpon destructans (8%), Epicoccum purpurascens (7,7%), Rhizoctonia solani (7,3%), Trichoderma hamatum (6%). Ochrona polepsza zdrowotność sadzonek, przy czym lepszy efekt ochronny uzyskano po zastosowaniu syntetycznych fungicydów, zastosowanie których prowadziło do zmniejszenia ilości izolatów grzybów z 541 w obiekcie kontrolnym do 266. Celem drugiego etapu badań była ocena in vitro aktywności przeciwgrzybicznej 1.0; 0.5; 0.1 mm3·cm-3 stężenia olejku jałowcowego wobec ww. gatunków grzybów. W warunkach laboratoryjnych olejek jałowcowy niezależnie od stężenia bardzo silnie hamował rozrost liniowy oraz zarodnikowanie grzybów najintensywniej zasiedlających sadzonki chrzanu. Średnie wartości ograniczenia rozrostu powierzchniowego kolonii mieściły się w przedziale od 50,66% - V. dahliae do 90,1% dla Rhizoctonia solani. Poza tym zwiększenie stężenia w podłożu hodowlanym olejku jałowcowego skutkowało wzmożoną inhibicją sporulacji grzybów. W obecności 1,0 mm3·cm-3 olejku w pożywce ilość spor C. destructans zmniejszała się o 90,4%, a V. dahliae o 81,1%. Bardzo silne fungistatyczne oddziaływanie olejku jałowcowego w testach in vitro, może być podstawą do dalszych badań w kierunku wykorzystania go do ochrony roślin przed zgniliznami korzeniowymi, których sprawcami są testowane gatunki grzybów.

Silvicultural assessment was based on the comparison of survival rate, defect differentiation as well as height and diameter growth of plants depending on the type of the planting material used for renewal. Results show faster growth of the container−grown plants but their slightly lower survival rate. The economic evaluation was based on the comparison of total costs of establishing and managing both types of plantations depending on the initial density.

Opis:
Entandrophragma angolense is a tropical tree species with a very slow growth rate. To overcome this barrier, a study on the effect of organic amendment on the growth rate of Entandrophragma angolense seedlings was conducted in the nursery section of the Department of Forestry and Wildlife, University of Benin, Benin City, Nigeria. Herein, 2kg polythene pots, each containing top soil were all amended with Poultry droppings (PRD), Cow dung (CWD) and Compost (CPT) at a ratio of 2:1, while top soil alone served as the control. Employing a completely randomized design (CRD), growth variables were recorded on a fortnight basis. The seedlings were assessed for height, number of leaves and collar diameter for a total period of 20 weeks. Fresh weights and total dry weights of the seedlings were also determined at the end of the experiment. No significant difference (p>0.05) was observed in the effect of organic amendments on the plant mean height and number of leaves throughout the study period, however, a significant difference was observed in collar diameter at 2 weeks after treatment and 12 weeks after treatment alone. Organic amendment was found to influence general biomass production in the specie, although there was no significant difference (p>0.05) in stem biomass production. Conclusively, organic amendment can be said not to have significantly (p>0.05) affected the growth of E. angolense, while this cannot be said of the biomass production, albeit at a low level of significance.

Opis:
The alkalization of soil is a common phenomenon in forest ground nurseries. Liming, inadequate fertilization and the use of hard water for irrigation are the main reasons for this alkalization. The aim of this study was to investigate the effect of fertilization with aluminium sulphate on soil pH, the activity of selected soil enzymes, efficiency as well as the growth parameters of pine seedlings. The study was conducted in a forest nursery, on a plot with soil pH 6.4 in water and 5.9 in 1MKCl. Such a pH is not conducive to the production of conifer seedlings, particularly pines. Two different doses of aluminium sulphate fertilizer were applied: 740 kg ha-1 and 1110 kg ha-1. Both doses significantly reduced the soil pH, whereas soil enzyme activity did not change. The lower dose had a positive impact on the growth parameters of pine seedlings, while the higher dose led to their deterioration. We observed statistically significant differences in average primary and lateral root lengths, number of short roots, and thickness of the neck root of seedlings. One- and 2-year-old seedlings did not show symptoms of nutrient deficiency and neither did concentrations of the investigated macronutrients and selected micronutrients in needles indicate such. After applying the higher fertilizer dose, we observed a favourable change in the composition of mycorrhizae. Out of the potential seedling pathogens we found Cylindrocarpon spp., Fusarium spp., Phytophthora spp., Pythium spp. and Rhizoctonia solani of which the most frequent were Fusarium oxysporum, Pythium spp. and R. solani. Their occurrence frequency differed between the treatments used in this experiment. This study confirms the positive effects of a low aluminium dose on the performance and growth parameters of pine seedlings. However, on the basis of the conducted experiments, it is difficult to say, whether this positive effect is due to a direct action of aluminium on the seedlings or rather an indirect effect caused by lowering the soil pH, which in turn impacts on mycorrhizae composition and hence pathogen development.

Opis:
Badania przeprowadzono w latach 2001–2005 na 10 polach uprawnych żyta ozimego w województwie lubelskim. W każdym sezonie wegetacji po przezimowaniu oceniano udział roślin z objawami nekrozy korzeni i pochew liściowych. Odsetek takich roślin wynosił od 3,5 w 2002 do 45 w 2004 roku. Natomiast wartości wskaźników chorobowych wynosiły od 0,7 w 2002 do 22,0 w 2001 roku i różniły się istotnie. Głównym patogenem żyta okazał się F. avenaceum (33,5% wszystkich Fusarium ssp.). W znacznych ilościach wyosabniano także F. culmorum (18,8%) oraz F. poae (8,7%). Badania fitotronowe dotyczące podatności siewek 10 odmian żyta na porażenie przez F. avenaceum nr 24 i F. culmorum nr 33 wykazały, że najbardziej podatne na te patogeny były odmiany Kier oraz Dańkowskie Złote, dla których wartości wskaźników chorobowych wynosiły odpowiednio 58,0 i 64,25 w przypadku infekcji podłoża przez F. avenaceum oraz 88,25 dla odmiany Kier i 70,5 w przypadku odmiany Dańkowskie Złote w kombinacji doświadczenia z F. culmorum. Najmniej podatną na porażenie siewek przez F. avenaceum i F. culmorum okazała się odmiana Gradan F1, dla której wskaźniki chorobowe wynosiły odpowiednio 25,5 i 41,25.
The investigations were carried out in 2001–2005 at 10 winter rye cultivation plots in the Lublin Province. The participation of plants with root and leaf sheaths necrosis was evaluated after winter in each vegetation season. The percentage of diseased plants ranged from 3.5 in 2002, to 45.0 in 2004. Mean values of the disease index ranged from 0.7 in 2002 to 22.0 in 2001 and differed significantly. The main pathogen of rye plants turned out to be the species F. avenaceum (33.5% of all Fusarium spp.). Considerable amounts of F. culmorum (18,8%) and F. poae (8.7%) were also detected. Investigation carried out in growth chamber on susceptibility of seedlings of 10 rye cultivars to infection with strains F. avenaceum 24 and F. culmorum 33 showed that the most susceptible genotypes to both these pathogens were cv. Kier and Dańkowskie Złote, for which values of the disease index amounted 58.0 and 64.25, respectively in the case of ground inoculation with F. avenaceum and 88.25 for cv. Kier and 70,5 for cv. Dańkowskie Złote in the experimental combination with F. culmorum. The least susceptible for seedlings infection with F. avenaceum and F. culmorum was cv. Gradan F1, for which values of the disease index amounted 25.5 and 41.25, respectively.

Accumulation of proline is a defense mechanism against external stress conditions, preventing damage to the structure and function of cells and improving plant development processes, such as germination. The purpose of this study was to investigate proline treatment as a means of improving the germination and development of Norway spruce seedlings. The effect of exogenous proline has been studied in three stages of initial plant development. The collected seeds were soaked in water or 8 mM proline solution and placed on the germinators. The germination capacity and the mean germination time were determined. Seedlings with radicles >10 mm were transferred to the sand-peat substrate at a constant temperature of 20 °C. Seedlings at 3 subsequent developmental stages (S1 – germinated seeds with radicles > 3 mm; S2 – seedlings with radicles >10 mm; S3 – established seedlings grown for 90 days) were examined for the oxygen consumption rate, total antioxidant capacity, hydrogen peroxide level, malondialdehyde level and intracellular proline content. Proline treatment was conducive to lowering the levels of hydrogen peroxide and malondialdehyde at stage S1. At the subsequent stages of development, the levels of hydrogen peroxide and malondialdehyde increased, and at the S3 stage, there was also a marked increase in total antioxidant capacity. At stage S3, the seedlings of the proline treatment were characterized by a lower total mass, and the response to exogenous proline was stronger in the root tissues than in the leaves. The oxygen consumption rate was higher for the proline treatment at all stages of development. Seedlings at the analyzed stages of establishment differed in response to proline treatment. Exogenous proline had some beneficial effects during the first phase of germination by reducing the level of hydrogen peroxide and improving the condition of lipid membranes. In the subsequent stages of seedling development, in response to the same concentration of proline solution, undesirable effects, such as an increase in hydrogen peroxide levels and damage to cytoplasmic membranes, were observed. Optimal concentrations of exogenous proline should be determined prior to commercial use of proline treatment to improve plant stress tolerance.

Opis:
The influence of fertilization with the compost prepared from treated sewage sludge with bark additive and mulching with the fresh forest ectohumus on the soil conditions, chosen parameters of two- and three-year old littleleaf linden seedlings growth as well as the occurrence of soil mites (Acari) was investigated in the paper. The experiments were carried out in 2009–2010 at forest nursery Białe Błota (Forest District Bydgoszcz) on the rusty soil. The whole area of the experiment was irrigated with the use of stationary sprinkling machine. The soil was characterized by the alkaline reaction (pH in H2O was in the range 7.2–7.4), the low content of available potassium and available phosphorus as well as the content of C-org from 35.7 to 38.4 g kg-1),. The C:N ratio ranged from 14.3 to 14.9. Two- and three-year old seedlings of littleleaf linden grown on plots fertilized with the compost were higher than those cultivated on plots with mineral fertilizer and they were also characterized by the higher number of leaves and the higher leaf area. Mulching – which was carried out in September of the first growing season – did not influence significantly on the growth parameters of two-year old seedlings (with the exception of the decrease in a leaf area). In the third growing season the mulching significantly influenced on all the seedling growth parameters tested, and – furthermore – there was also a significant interaction between the both studied treatments in shaping of the all growth parameters (with the exception of the plant height) of littleleaf linden seedlings. The density of mites in the soil was distinctly increased after the mulch-ing treatment , and it was many fold higher as compared to the control plot MC. On the base of the analysis it was found that the mulching and the fertilization with compost prepared from municipal sewage sludge influenced positively on the abundance of mites, especially oribatid mites as well as on their species diversity. Tectocepheus velatus was the most abundant species among the oribatid mites on all the stands of littleleaf linden cultivation. Abundance dynamics of this oribatid species in the two-years period of the study, especially on the variant with mulching and organic fertilization, indicates the upward trend in the number of its population.

Opis:
The study was conducted in the years 2008-2010 in the bare root nursery Białe Błota that produced pine, beech and linden, and belonged to Bydgoszcz Forest District. The experiments included the following variants: C – control, O – organic fertilization, M – mulching with raw humus, OM – organic fertilization and mulching with raw humus. Relatively small but significant increase in the number and diversity of Oribatida species was observed in O variant for the deciduous trees. Mulching was the soil revitalization method that clearly improved the density and biodiversity of Oribatida species. In total, the investigated area harbored 37 species of oribatid mites. The most effective bioindicator and stimulant of soil revitalization was a common fungivorous species Tectocepheus velatus.
Badania były prowadzone w latach 2008-2010 w należącej do Nadleśnictwa Bydgoszcz, szkółce leśnej Białe Błota produkującej sosnę, buk oraz lipę. Badania prowadzone były w następujących wariantach: C – kontrola, O – nawożenie organiczne, M – mulczowanie świeżym humusem, OM – nawożenie organiczne i mulczowanie świeżym humusem. Stosunkowo mały, ale znaczący wzrost liczby i zróżnicowania gatunkowego mechowców zaobserwowano w wariancie O dla drzew liściastych. Mulczowanie było metodą rewitalizacji gleb, która wyraźnie wpłynęła na intensywność i zróżnicowanie gatunkowe mechowców. Na badanej powierzchni stwierdzono ogółem 37 gatunków mechowców. Najskuteczniejszym bioindykatorem i stymulatorem rewitalizacji gleby był powszechnie występujący gatunek grzybożerny Tectocepheus velatus.

Opis:
Selen jest niezbędnym mikroelementem o właściwościach przeciwutleniających. Brokuł ma zdolność do akumulowania selenu z gleb i pożywek wzbogacanych w jego związki. Celem prezentowanej pracy była ocena wpływu dodatku selenu (w postaci Na2SeO3) na aktywność antyoksydacyjną i zawartość chlorofilu w jadalnych siewkach brokułu. Zastosowano różne stężenia Na2SeO3: 10, 50 oraz 100 μg na 1 g nasion. Obserwacje morfologiczne siewek brokułu na wczesnych etapach kiełkowania pozwalają na stwierdzenie, że dodatek selenianu(VI) sodu przyspiesza proces kiełkowania nasion i wykształcania korzenia zarodkowego. Siewki brokułu hodowane z dodatkiem selenianu charakteryzowały się większą biomasą w porównaniu do roślin kontrolnych. Oznaczając stężenie chlorofilu, stwierdzono, że stężenie chlorofilu a było wyższe niż chlorofilu b zarówno w kontroli, jak i w siewkach hodowanych z dodatkiem selenianu. Dodatek selenianu przyspieszał proces wytwarzania chlorofilu w siewkach brokułu, co wyraźnie stwierdzono w czwartym dniu hodowli. Dodatek selenianu stymulował także wytwarzanie chlorofilu b w siewkach brokułu w początkowym okresie ich wzrostu. Stężenie chlorofilu w próbkach z selenianem było wyższe niż w kontroli w początkowym okresie wzrostu siewek. Jednak w kolejnych dniach hodowli zawartość chlorofilu w kontroli zwiększała się szybciej niż w próbkach z selenianem. Wewnątrzkomórkowe stężenie selenu wpływa na procesy fizjologiczne zachodzące w roślinach. Oznaczając całkowitą zdolność antyoksydacyjną w ekstraktach z siewek brokułu, stwierdzono, że w czwartym dniu hodowli zawartość antyoksydantów wyrażona w ekwiwalencie troloksu była podobna w próbkach kontrolnych i rosnących w obecności selenianu. W 5 i 6 dniu hodowli obserwowano spadek całkowitej zdolności antyoksydacyjnej (CZA) we wszystkich próbkach. W szóstym dniu hodowli siewki rosnące w obecności selenianu charakteryzowały się niższą wartością CZA niż obiekt kontrolny. Związki selenu w zależności od stężenia mogą działać prooksydacyjnie na komórki roślin.
Selenium is an essential micronutrient with antioxidant properties. Broccoli is capable of accumulating selenium from the soil and from media enriched with its compounds. The aim of the study was to evaluate the effect of selenium supplements (in the form of Na2SeO3) on the antioxidant activity and chlorophyll content of edible broccoli seedlings. Different concentrations of Na2SeO3 were used: 10, 50 and 100 μg per 1 g of seeds. Morphological observations of the broccoli seedlings during the early stages of germination indicate that sodium selenate supplementation accelerates the germination process and radicle formation. Broccoli seedlings grown with selenate had greater biomass than the control plants. Determinations of chlorophyll concentration showed that chlorophyll a concentration was higher than that of chlorophyll b both in the control and in the seedlings grown with selenate. Selenate accelerated the chlorophyll-production process in the broccoli seedlings, which could be clearly seen on the fourth day of growth. Selenate supplementation also stimulated production of chlorophyll b in the broccoli seedlings during the initial period of growth. Chlorophyll concentration in the samples with selenate was higher than in the control in the initial period of growth. On successive days of growth, however, chlorophyll content in the control increased faster than in the samples with selenate. The intracellular concentration of selenium affects physiological processes taking place in the plants. Determination of total antioxidant capacity in the broccoli seedling extracts showed that on the fourth day of growth antioxidant content expressed as trolox equivalent was similar in the control samples and those grown in the presence of selenate. On days 5 and 6 of growth, a decrease in TEAC was observed in all samples. On the sixth day, the seedlings grown in the presence of selenium had lower TEAC than the control samples. Selenium compounds, depending on their concentration, can have a pro-oxidant effect on the cells of the plants.
