Opis:
Celem pracy była ocena przydatności pomiarów biometrycznych podczas wegetacji wierzby do prognozowania plonu biomasy pędów. Nowością pracy jest podjęcie tego tematu. Doświadczenie ścisłe założono metodą losowanych podbloków w układzie zależnym w latach 2006-2009 w rejonie Koszalina na glebie lekkiej o bardzo głębokim poziomie wody gruntowej (ok. 950 cm). Utworzono równania regresji wielokrotnej dla plonu biomasy pędów (Y), gdzie zmiennymi niezależnymi były pomiary biometryczne długości (x1), grubości (x2), liczby pędów w krzaku (x3) oraz współdziałania długości i grubości pędów (x4). Badania wykazały, że pomiary biometryczne pędów w okresie wegetacji mogą być brane pod uwagę przy prognozowaniu plonu biomasy wierzby.
The aim of the research was to evaluate usefulness of biometric measurements of willow for prognosis of shoots biomass yield. This problem has not been considered so far. In the years 2006-2009 strict experiments were conducted on the light soil with very low ground water level (about 950 cm) near Koszalin, Poland, using the method of random sub blocks. The data obtained from measurements of shoots and biomass yield were statistically analysed. There were created multiple regression equations for biomass yield of shoots (Y), in which independent variables were biometric measurements of length (x1), thickness (x2), number of shoots in the bush (x3) and thickness of shoots (x4). Dependencies between the data from biometric measurements and the yield of fresh mass of shoots were investigated in two configurations: (1) together for all years analysed (data from 5400 measurements) and (2) separately for each year (data from 1080 measurements). For 21 from among 24 of the created regression formulas the determination coefficients were higher than 60%. This proves that the prognosis of yields was correctly made. The differences between the prognosed and real yield were smaller when using method (2) than when using method (1). Among nine varieties the average year increase of fresh mass of willow shoots was: in two year cycle - 12.070 toha-1, in 3 year cycle - 13.300 toha-1, and in 4 year cycle - 13.801 toha-1. The conducted investigations showed that biometric measurements of length, thickness of shoots and number of shoots in a bush during the vegetation period can be taken into account when prognosing the biomass yield. Further experiments are necessary to improve the prognostic equations by introducing quantified conditions of tillage in the analysis.

Opis:
The present study was aimed to find out whether the preformation of future shoot’s organs within a bud is reflected in the bud size/shoot functional traits’ size relationships. The survey attempts to evaluate whether relationships between the bud mass and stem mass, leaf mass, leaf area, total mass and number of leaves, respectively, of spring-shoot sprouted by the bud in Fagus sylvatica (L.) saplings are affected by parental bud location within shoot and parental shoot type. Dry mass of the terminal bud, the first and the last lateral buds placed on terminal and uppermost lateral shoots was estimated nondestructively for 58 beech saplings in December 2008. The shoots sprouted from the measured buds were sampled at the end of growing season, in August 2009. Bud mass, parental shoot type and bud location explained about 90% of shoot traits variability in full-factorial ANOVA. The leaf mass was the only shoot trait not affected by parental shoot type and bud location within shoot in scaling relationship with bud mass. There was not found differences among intercepts across parental shoot types and bud locations, however significant shift along common slope was observed among them. The presented findings could be viewed as a confirmation of the preformation and full development of leaf primordia within the European beech buds prior to bud burst.

Opis:
Najważniejszym źródłem energii odnawialnej w Polce jest biomasa, a jej udział w bilansie paliwowym wynosi około 90% [4]. W ostatnich latach znaczenia nabiera biomasa rolnicza, szczególnie z drzew szybko rosnących. Zapotrzebowanie energetyki na biomasę jest bardzo duże - ok. 17,5 mln ton [3]. Wyprodukowanie takiej ilości biomasy każdego roku wymaga opracowania efektywnej technologii jej pozyskiwania, z uwzględnieniem gatunków roślin i odmian, oraz warunków uprawy i zbioru. W Polsce duże nadzieje pokłada się z uprawą wierzby krzewiastej. Ograniczenie nakładów finansowych na jej uprawę, może zachęcić do rozwijania produkcji biomasy stałej z wierzby. Celem pracy była ocena dynamiki odrastania pędów dziesięciu odmian wierzby krzewiastej (Salix viminalis) w trzyletnim cyklu, uprawianych w rejonie Koszalina, na glebie lekkiej, o głębokim poziomie wody gruntowej, zróżnicowanym zagęszczeniu krzaków na hektarze.
This experiment was conducted to assess regrowth of shoots of Salix viminalis in the three-years-cycle of cultivation, of ten varieties of willow, on the light soil, at different density of planting bushes per hectare (15 020, 22 134 and 35 200 pieces). The importance of studied factors on the variability of height, thickness and number of live shoots in bush in order of decreasing main effects was as follows: years of shoots regrowth, time of measurement, varieties and density of planting of willow. Following interactions: years of willow shoots regrowth with varieties and varieties of willow with planting density were important for all features. Increase shoots length were arranged according to the rainfall during the growing season of willows and were highest in 2009, lower in 2010, and the lowest in 2008. The longest shoots were in the objects with density of planting 22 thousand of bushes and the shortest at planting of 15.0 thousand of bushes per hectare. Number of living shoots in the bush decreased with increasing density. On average, the longest and thickest shoots had Ekotur variety, shortest - Start variety, and thinnest - 1054 variety The least living shoots in the bush was found in Oloff variety the most Sprint variety. The longest shoots in all planting densities had Ekotur variety, and the shortest varieties: 1047 at planting 15 020 bushes per hectare, 1054 at planting 22 134 bushes per hectare, and 1047D at planting 35 200 bushes per hectare. The biggest differences of shoot length between the planting densities were observed for Oloff variety, and the smallest - for Start variety. The dynamics of decreasing of number of living shoots between planting densities was different for varieties of willow. The biggest differences in the number of living shoots between the planting densities was observed for 1047D variety, and the lowest - for 1047 variety.

Opis:
Badania zrealizowano w latach 2013–2015 w Krakowie. Ich celem była ocena wielogatunkowej i wieloodmianowej mieszanki rozrzuconych pędów rozchodników do wczesnojesiennego zadarniania ekstensywnych dachów zielonych, pod względem wybranych cech biometrycznych. Mieszanka składała się z 13 gatunków z rodzaju Sedum. Dwa z nich Sedum album i Sedum spurium były reprezentowane każdy przez cztery odmiany, pozostałe przez jedną odmianę. Pod względem ukorzeniania się oraz przezimowania najbardziej odpowiednie do wielogatunkowej mieszanki stosowanej wczesną jesienią były: Sedum acre, Sedum album‚ ‘Coral Carpet’‚ ‘Laconicum’, ‘Micranthum Chloroticum’, ‘Murale’, Sedum cyaneum, Sedum oreganum, Sedum rupestre, Sedum sexangulare oraz Sedum spurium ‘Fuldaglut’, Roseum’. Po pierwszym roku badań z mieszanki wypadły: Sedum ewersii, Sedum floriferum Weihenstephaner Gold’, Sedum hispanicum oraz Sedum lydium. Gatunki o większej masie wegetatywnej tj.: Sedum hybridum, Sedum kamtschaticum ‘Variegatum’ oraz Sedum spurium ‘Album Superbum’ i ‘Variegatum Tricolor’ miały trudności z ukorzenianiem się. Ponadto ich stan wiosną w drugim roku badań określono, jako: bardzo zły, zły lub zły do przeciętnego, a więc w porównaniu do gatunków o mniejszej masie wegetatywnej był dużo gorszy.
The research was carried out in the period 2013–2015 in Krakow. Its objective was to assess the usefulness of multispecies and multi-cultivars mixture for sodding for extensive green roofs. The blend of scattered stonecrops shoots comprised of 13 species of the genus Sedum were evaluated in terms of selected biometric features Two of them, Sedum album and Sedum spurium, were represented by four varieties each while others – by a single variety. In terms of rooting and wintering, most suitable for multi-species blend used in the early autumn were: Sedum acre, Sedum album, ‘Coral Carpet’, ‘Laconicum’, ‘Micranthum Chloroticum’, ‘Murals’, Sedum cyaneum, Sedum oreganum, Sedum rupestre, Sedum sexangulare and Sedum spurium ‘Fuldaglut’, ‘Roseum’. After the first year of research: Sedum ewersii, Sedum floriferum ‘Weihenstephaner Gold’, Sedum hispanicum and Sedum lydium disappeared from the mixture. Species with greater mass of the plant, i.e.: Sedum hybridum, Sedum kamtschaticum ‘Variegatum’ and Sedum spurium ‘Album Superbum’ and ‘Variegatum Tricolor’ had difficulties with rooting. Furthermore, their condition in the spring of the second year of the study was defined as very bad, bad, or bad to average and significantly worse in comparison to species with a smaller mass.

Opis:
Drzewa iglaste od dawna stosowane są jako źródło związków o potencjale terapeutycznym, prozdorowotnym, a także jako surowce zawierające charakterystyczne substancje zapachowe i smakowe. Obecnie jednak, poza korą, różne części drzew iglastych nie znajdują zastosowania w wielu gałęziach przemysłu. Pędy są prawie nieobecne jako składnik żywności oraz kosmetyków i innych produktów prozdrowotnych, pomimo ich szerokiej dostępności, niskiej ceny i możliwości ekologicznego ich pozyskania. Celem pracy była ewaluacja ekstraktów wodnych z utrwalonych przez liofilizację pędów wybranych drzew iglastych tj. świerk pospolity (PA), modrzew europejski (LD), daglezja zielona (PM) i jałowiec pospolity (JC) jako źródła związków bioaktywnych i aktywności przeciwutleniającej. Przeprowadzone analizy wykazały, że wszystkie z badanych ekstraktów cechowały się zawartością związków bioaktywnych o aktywności przeciwutleniającej. Największą zawartością badanych związków fenolowych cechował się ekstrakt PA (19750 µg/g s.m), następnie JC (12139 µg/g s.m), LD (11553 µg/g s.m), a najniższą PM (10489 µg/g s.m), z kolei w badaniu ogólnej zawartości fenoli, najwyższy wynik uzyskały ekstrakty LD i PA, aczkolwiek mimo niższej zawartości badanych składników bioaktywnych, największą zdolnością do hamowania wolnych rodników DPPH cechowały się ekstrakty JC i PM.
Coniferous trees have long been used as a source of compounds with therapeutic and health-promoting potential, as well as raw materials containing characteristic aroma and flavor substances. Today, however, except for the bark, various parts of coniferous trees are not used in many industries. Shoots are almost absent as an ingredient in food as well as cosmetics and other health-promoting products, despite their wide availability, low price and the possibility of obtaining them organically. The aim of this study was to evaluate aqueous extracts from freeze-fixed shoots of selected conifers, i.e. european spruce (PA), european larch (LD), douglas fir (PM) and common juniper (JC), as a source of bioactive compounds and antioxidant activity. The analysis showed that all of the tested extracts were characterized by the content of bioactive compounds with antioxidant activity. The PA extract had the highest content of tested phenolic acids (19750 µg/g d.w), followed by JC (12139 µg/g d.w), LD (11553 µg/g d.w), and the lowest PM (10489 µg/g d.w), while in terms of total flavonoid content, LD and PA extracts had the highest result, although despite the lower content of tested bioactive components, JC and PM extracts had the highest ability to inhibit DPPH free radicals.

Opis:
Saponaria officinalis L. is a medicinal plant from the family Caryophyllaceae. It occurs in most European countries, as well as in North Africa, America and Western Asia. The aim of the study was to find an optimal method of sterilization S. officinalis seeds in order to obtain sterile seedlings and to multiply axillary shoots from nodal explants isolated from them, on MS medium with the addition of growth regulators (RW). In this study, 4 variants of seed sterilization were compared using NaClO at the following concentrations: 1.5% (2), 2% (3) and 2.5% (4) for a period of 11 minutes. The control was a variant in which 70% C2H5OH was used for pre-sterilization for 1 minute (1). The highest percentage of sprouted, seeds and sterile seedlings and the lowest percentage of contamination were obtained in variant (4). As a result of micropropagation of soapwort in in vitro cultures, axillary shoots were formed from nodal explants from axillary buds. The highest percentage of explants with shoots (95%) and callus tissue (48%) and the highest number of shoots from one explant (5.95) were obtained in the second passage on MS medium with the addition of 4 mg.dm-3 BAP and 0.5 mg.dm-3 NAA. Due to the wide possibilities of using soapwort, it is advisable to continue research aimed at developing an optimal and efficient plant regeneration system of this species.

Opis:
The purpose of the study was to determine which fungal species colonize the shoots of apple, pear, cherry, plum, apricot and peach in south-eastern Poland and whether Diaporthe (Phomopsis) isolates there are among them. The study was conducted in 2010–2012 and the plant material was collected from five orchards. In three of these chemical controls were carried out, while there was no protection applied in the other two. The results showed that species composition of the fungi was very similar regardless of host plant and year of study. Alternaria spp., Fusarium spp. and Phoma spp. were isolated most frequently from the studied shoots. Fungi cultures known for pathogenicity towards fruit trees such as Botrytis cinerea, Colletotrichum gloeosporioides, Leucostoma spp., Monilinia spp. and Neofabraea spp. were also isolated. Moreover, there were isolates of Diaporthe (Phomopsis) among the fungi present in the shoots. Cultures of these fungi were obtained both from shoots with disease symptoms and from visually healthy ones but mainly from shoots originating from unprotected orchards, what indicates their greater threat to fruit trees grown without chemical protection. This is the first documented report of the occurrence of Diaporthe (Phomopsis) on fruit trees in Polish conditions.

Opis:
This work is a continuation of research on Diaporthe genus isolates obtained in 2010−2012 from fruit trees in Poland, which on the basis of previously conducted molecular tests, have been identified as one species belonging to the Diaporthe eres species complex. The aim of this study was to determine the morphology and pathogenic abilities of tested Diaporthe eres isolates. The experiment included cross tests, in which the shoots of apple, pear, cherry and plum trees were inoculated with each of the 4 isolates derived from each mentioned host plants. As a result of experiment, the pathogenic nature of D. eres in relation to the shoots of fruit trees, was confirmed. The isolates were also characterized on the basis of the colony appearance and spore dimensions. Morphological features of studied D. eres cultures were very similar, regardless of the isolate and the host plant, from which they were obtained. All tested isolates formed alpha and beta conidia having the same range size.

The study shows the content of macro- and microelements in the leaves and rhizomes of Glyceria maxima of the Słupia River in Słupsk. The content of macro and micro-elements in G. maxima was analyzed for each component separately and in an integrated way, and comparing the demand for nutritions. The largest quantity of nitrogen, phosphorus, potassium, magnesium and calcium were found in the leaves, meanwhile zinc, iron, manganese, nickel and copper in the G. maxima rhizomes. The amount of Zn and Cu, in all of the tested positions, within the range of the limit for the plants, and the concentrations of Ni and Mn exceed physiological needs. The U Mann Whitney test showed a number of statistically significant differences in the concentration of the analyzed elements in leaves – rhizomes, leaves – bottom sediment and rhizome bottom sediment relation. The relations between designated heavy metals formed a following series: Mn>Fe>Zn>Ni>Cu in leaves and Fe>Mn>Zn>Ni>Cu in rhizomes. The G. maxima shoots accumulated 985.8 do 1441.4 mmolc∙kg-1 in all the analyzed components, and the lower value of the sum of the accumulated macro and microelements were found in rhizomes. The sum of ion comospition of the macronutrients in the leaves and rhizomes was similar. The content of nitrogen was 51.7–53.7% of this amount, 5.8–8.6% phosphorus, potassium 22.8 – 26.6%, 4.9-5.8% of magnesium, calcium, 8.2–11.9%, and trace elements were 0.58% in total, in the case of leaves and 8.70% in the rhizomes.

Opis:
The article examines the influence of physicochemical traits on yield depending on the variety and year of cultivation. Four common to Poland grape cultivars, i.e. ‘Regent’, ‘Rondo’, ‘Seyval Blanc’, and ‘Solaris’, were evaluated by analysing, among others, number of clusters per bush, their weight, number of berries, and the yield per hectare, number of woody shoots, weight of woody shoots, and the diameter of woody shoots. Energy and emission parameters were evaluated by conducting technical evaluation (lower heating value, ash content, volatile matters content, moisture content, fixed carbon) and elemental analysis (carbon, nitrogen, hydrogen, sulphur and oxygen contents) of one-year, two-year and three-year vine shoots. In addition, emission factors for CO, CO2 , NOx, SO2 and dust were estimated. The study showed that there was no significant differences between years under study (2020, 2021 and 2022) and energy and emission parameters. It was observed that the highest LHV (lower heating value) occurred in the ‘Regent’ cultivar while the lowest level in the ‘Rondo’ cultivar. As regards energy-emission parameters, a significant influence of cultivar (‘Solaris’, ‘Rondo’, ‘Seyval Blanc’ and ‘Regent’) was shown on the parameters studied except for nitrogen content and NOx emission index. The interaction of year and cultivar showed no significant differences except for the moisture content.

Opis:
The results of PCR examination indicated that during two years of tissue culture at standard conditions, on the medium with BAP 1 mg l-1 and continuous temperature of 20oC, phytoplasma could be detected in diseased plants of rose cv Sacha and Jazz. In the second year of micropropagation phytoplasma detection rate in tissues of infected roses increased and was relatively higher than in the first one. To test whether phytoplasmas are sensitive to temperature and light intensity, phytoplasma-affected micropropagated rose plants were grown on medium with BAP 1.0 or 0.5 mg l-1 and at the temperature of 4, 15, 20 or 25oC in darkness or in the light. PCR analysis indicated that phytoplasma detection was not effected by these conditions during 4 weeks of culturing. However, phytoplasma was not detectable in rose plants after 8 weeks culturing on the same medium without transplanting. Micropropagated rose shoots maintained on medium with Gentamycin or Baytril at the concentration of 25.0 or 50.0 mg l-1 had reduced growth and were chlorotic. However, no direct effect of applied antibiotics on phytoplasma detection was evidenced.

Opis:
In a pot experiment conducted in a greenhouse, the effect of CCC Bercema growth inhibitor to reduce vegetative shoot growth of perennial ryegrass and cocksfoot was studded. The experiment was set up in triplicate. Growth regulator was applied once, in a form of an aqueous solution. The following experimental objects were specified: control object, Bercema with a concentration of 10%, 20% and 30%. Ten measurements were performed every 3 days. The study was conducted under conditions of 12-hour artificial light daily. The results were statistically analyzed using two-factorial variance analysis . It was found that the greatest shoot growth reduction of ryegrass due to the highest inhibitor concentration (B- 30%), but for cocksfoot under the influence of the minimal concentration (B- 10%), compared to the control object. It has been noted that cocksfoot is more sensitive to the applied growth regulator, resulted in significantly greater inhibition of shoot regrowth than for ryegrass. In the experiment with the perennial ryegrass significant differences in the growth of shoots were found under the influence of inhibitor application at a concentration of 30%, compared to the control object. In the case of cocksfoot, all the concentration increases of Bercema inhibitor significantly differentiated the shoots regrowth.

Opis:
The paper presents results of the study on infestation of dwarf shoots of Larix decidua Mill. by Dasineura kellneri Henschel (Diptera, Cecidomyiidae) and Adelges laricis Vallot (Homoptera: Adelgidae). The branches with dwarf shoots (a total of 39 337) were collected in the Ojców National Park and the Krzeszowice Forest District (southern Poland) in 2010. At both localities A. laricis and D. kellneri destroyed 23.1% and 24.6% of the dwarf shoots respectively. There is significant differences in the occurrence of D. kellneri and the average number of the undamaged dwarf shoots for the Ojców site. The same situation is observed in case of A. laricis occurrence in the Krzeszowice Forest District.

Opis:
The frequency of occurrence of abnormal, three- (or more) needle dwarf shoots of most southern and central European two-needle pine (Pinus) species were studied. No specimens with more than two-needle dwarf shoots were found in a population of P. nigra Arnold subsp. salzmannii (Dunal) Franco from the Iberian Peninsula and in two populations of P. uliginosa Neumann from the Sudeten Mountains in Central Europe. Single specimens were found within one population of P. pinaster Aiton from the Iberian Peninsula and among six populations of P. sylvestris L. from the Iberian Peninsula and Central Europe. Abnormal dwarf shoots mostly with three, but also four, five or six needles were found among 24 of 25 surveyed populations of P. mugo Turra and P. uncinata Ramond. The average frequency of specimens with at least one three-needle dwarf shoot was 24% for P. mugo and 20% for P. uncinata. The frequencies of occurrence varied significantly among studied populations and were highest in samples collected from the upper elevational range limits of the species in the mountains and near the northern limits of their ranges. The frequency of abnormal dwarf shoots in the same populations was significantly high in 2-3 consecutive years. Needles from three-needle dwarf shoots were not significantly shorter than those of two-needle shoots.

Opis:
Zjawisko chimeryzmu związane jest z hodowlą chryzantemy wielkokwiatowej na drodze mutagenezy. Chimery, zwłaszcza sektorialne i meryklinalne, u których zmiana barwy pojawia się tylko na niewielkim obszarze całego kwiatostanu, są interesującym źródłem dotychczas traconej zmienności. Ze względu na lokalizację mutacji i mały obszar tkanek objętych mutacją w kwiatostanie, nie można stosować znanych metod separacji genotypów składowych chimer. Jedyną możliwością wyizolowania zmienności jest regeneracja pędów lub zarodków przybyszowych z kwiatów języczkowatych lub ich fragmentów o zmienionej barwie pobieranych z kwiatostanów chimer. Praca przedstawia znaczenie kultur in vitro kwiatów języczkowatych w hodowli chryzantemy oraz opisuje czynniki wpływające na wydajność regeneracji pędów i zarodków przybyszowych.
Chrysanthemum is one of the most popular ornamental plant worldwide. There is always demand for new cultivars, especially with new colour or inflorescence type. Very important breeding method of chrysanthemum is induced mutagenesis. Nevertheless this method is associated with a phenomenon of chimerism when mutation occurs within the meristem and plants with tissues of a varied genetic composition are formed. In chrysanthemum chimeras are also often formed as a result of spontaneous mutation during cultivation. In sectorial chimeras the genetically different tissue sector covers all the histogenic layers. In periclinal chimeras a different genotype is presented in one or two whole layers and in mericlinal chimeras only in a part of one or two layers. Chimerism is large limitation for mutation breeding focused mainly on obtaining new genetically stable cultivars. Chimeras, especially sectorial and mericlinal, in which the colour change occurs only on small area of the whole inflorescence, are very often an interesting source of variability. Nevertheless in this case, due to the location of the mutation and a small area of the mutated t issue like one or few ligulate florets or only single spots or stripes on ligulate florets, known methods of chimeras components separation can not be applied and these mutations get lost. The only possibility to isolate the variability is the in vitro regeneration of adventitious shoots or embryos from ligulate florets collected from chimera inflorescences. Adventitious shoots or embryos regenerated in vitro from single cells of histogenic layer L1 or L2 of ligulate floret, will present, respectively, the genotype of layer L1 or L2 and will be built up only from genetically homogenous tissues. In the paper the importance of in vitro cultures of ligulate florets in chrysanthemum breeding is presented and the factors affecting the efficiency of the regeneration of adventitious shoots and embryos (type and concentration of plant growth regulators in the medium, explant age and type, position of explant inoculation on the medium) are described in details. Ligulate florets of chrysanthemums are not only useful explants for chimera components isolation but can be also used as a good source of explants for irradiation.
