Opis:
The aim of the study was to evaluate the content of Zn, Cu, Mn, Pb, Hg and Fe in sandy everlasting, yarrow and stinging nettle in relation to the concentration of metals in the soil. Samples of soils and plants were collected from natural habitats (edges of forests in the Kujawy-Pomerania Province). The total metal content and their available forms for plants in the soil samples were determined. The stinging nettle inhabited the richest environmental areas in which anthropogenic accumulation of metals in the surface of soils was determined. The investigated soils were not contaminated with heavy metals and the content of their plant-available forms was not harmful for a proper plants growth. The content of metals extracted with the diethylenetriaminepentaacetic acid was considerably higher than the concentration referred to as the deficit level for plants. Among the analyzed herbal plants, sandy everlasting contained the largest amounts of copper, manganese, and only concentration of lead in dry weight was higher than 10 mg⋅kg⁻¹, indicating that the plants harvested from the study areas should not be used in herbal medicine. Bioconcentration factor (BCF) values point clearly to the mercury and zinc accumulation in the aboveground parts of herbal plants.

Opis:
The plant material were plants of sandy everlasting (Helichrysum arenarium (L.) Moench) collected from natural locations in October 2012. Initial explants were apical buds enfolded into two leaves. Isolated explants were chemically sterilized. Reproducted shoots were divided and put into three types of mediums: medium MS (control) containing 37 mg P·dm-3, medium MS without additive of P (0,0 mg P·dm-3), medium MS with additional amound of P (74 mg P·dm-3). The aim of research was to specify the influence of phosphorus content in medium for choosen growth parameters and accumulation of assimilatory pigments: chlorophyll a, b, chlorophyll a+b, carotenoids. Analysis of these compounds were done spectrophotometrically. The made research, proved, that the richest in mentioned substances were microseedlings growing on the medium with increased amount of phosphorus. Phosphorus deficiency in medium MS had a statistically essential effect on changes in growth modifications of microseedlings of sandy everlasting (Helichrysum arenarium (L.) Moench). Additional amount of phosphorus in the medium had a statistically essential effect on increasing of chlorophyll a+b in comparison with plants growing on the medium MS with optimal phosphorus amount or without this element by accordinglly 36% and 23%. Moreover, it caused a growth of content of chlorophyll a, b and carotenoids by accordinglly 18%, 32%, 20% in comparison with variant, where the medium MS without phosphorus was applied.

Opis:
There has been a growing interest over the last years in techniques using alternative and pharmaceutical plants due to their wide potential applications. These species are characterised by valuable and multidirectional usable features, due to which their practical application is superior to their physiognomic features. These plants may provide a raw material for production of medicines, cosmetics or may be used for animal feeds. Moreover they may be used as ornamental, melliferous and energy plants. Owing to their generally low soil requirements they are used in the reclamation of degraded land. Among the species characterized by multidirectional use are Silphium perfoliatum, Helichrysum arenarium and Stevia rebaudiana. These plants are characterized by a high content of active compounds and a number of pro-health characteristics. Because raw materials for production of medicines and cosmetics should be standardized, cultures maintained under controlled conditions are a good source of seedlings.

Opis:
Allium ursinum L. has a commercial value due to its high contents of bioactive compounds and mild, garlic-like taste. In vitro culture played an important role in obtaining Allium species with the desired characteristics and in the production of healthy reproductive material. Developing an effective method of sterilization bear’s garlic bulbs. To obtain sterile shoots of garlic several methods of sterilization involving such factors as ACE, H2O2, HgCl2, and UV-C were tested. In order to obtain sterile shoots of bear’s garlic, several sterilization procedures were tested. The best procedure was based on a two-step disinfection, where the whole onions were treated with ethanol and H2O2 for 20 min. Thereafter, the isolated apical buds were sterilized in ACE for 10 min, rinsed in double-distilled water and transferred onto MS medium for growing. Up to 95% of the inoculated explants formed shoots, which were sub-cultured on MS with 4 mg dm-3 BAP in order to enable further propagation. After optimization and stabilization, this procedure may become the basic concept of a proper and reliable propagation method of bear’s garlic on commercial scale.

Opis:
Explants of apical buds of sandy everlasting Helichrysum arenarium L. Moench sterilized with calcium hypochlorite – Ca(OCl₂) were placed onto Murashige- -Skoog (MS) growth medium enriched with 1 mg∙dm⁻³ KIN (kinetin) in two consecutive passages. To optimize the procedure of in vitro micropropagation, the axillary shoots of Helichrysum arenarium L. Moench were transferred during the third passage onto 9 different combinations of MS medium without plant growth regulators (PGRs-free medium), with different concentrations of KIN (1.0, 3.0, 4.0, 5.0 mg∙dm⁻³) and KIN (1.0, 3.0, 4.0, 5.0 mg∙dm⁻³) with IAA (indole-3-acetic acid) (0.5 mg dm⁻³). The highest mean number of shoots (24.7) was observed on MS medium with 5 mg∙dm⁻³ KIN and 0.5 mg∙dm⁻³ IAA. The achieved branched shoots were rooted and acclimatized. Rhizogenesis was intensified by the presence of growth hormones: 0.5 mg∙dm⁻³ IAA or 0.5 mg∙dm⁻³ IBA (indole-3-butyric acid). At the stage of acclimation of plantlets the application of a water solution of MS salts (25%) for watering the plants increased the efficacy of plant acclimation from 56 to 75%.

Moench wykładano w dwóch kolejnych pasażach na pożywkę MS [Murashige i Skoog 1962] wzbogaconą w 1 mg∙dm⁻³ KIN (kinetyna). W celu optymalizacji procedury mikrorozmnażania w kulturach in vitro w trzecim pasażu pędy boczne inokulowano na 9 wariantów pożywek MS bez regulatorów wzrostu, z dodatkiem KIN (1,0; 3,0; 4,0; 5,0 mg∙dm⁻³) oraz KIN (1,0; 3,0; 4,0; 5,0 mg∙dm⁻³) i kwasu indolilo-3-octowego – IAA (0,5 mg∙dm⁻³). Największą średnią liczbę pędów (24,7) odnotowano na pożywce z dodatkiem 5 mg∙dm⁻³ KIN (kinetyna) i 0,5 mg∙dm⁻³ IAA (kwas indolilo-3 octowy). Uzyskane pędy boczne poddano ukorzenianiu i aklimatyzacji. Proces ryzogenezy intensyfikowała zawartość regulatorów wzrostu 0,5 mg∙dm⁻³ IAA i 0,5 mg∙dm⁻³ IBA (kwas indolilo 3-masłowy). Na etapie aklimatyzacji mikrosadzonek zastosowanie do nawadniania 25% roztworu soli MS spowodowało poprawę efektywności aklimatyzacji roślin z 56 do 75%.

The aim of the study was to determine the influence of drip irrigation on the nutritive value of winter squash ‘Rouge vif d’Etampes’ fruits analyzed directly after the harvest and after the storage. The plants were grown on the very light soil in the region of decreased rainfall amounts during the vegetation period. The field experiment was conducted in 2007-2008 at Kruszyn Krajeński near Bydgoszcz on the soil of quality class V-VI (very weak and weak-rye-soil-complex). The field water capacity in the soil layer 0-50 cm was 57.5 mm, while the effective useful retention amounted 29.3 mm. The experiment was designed as one-factorial trial in four replications; drip irrigation as the experiment factor was applied. As the control the plots without irrigation were considered. The single plot area was 11.2 m2. The drip irrigation was conducted according to the soil tensiometer indications (-0.04 MPa). The research material was the eatable parts of fresh fruits that were analyzed directly after the harvest and after the storage for six months at the temperature 10°C and the relative air humidity 75%. The drip irrigation performed during the cultivation of winter squash increased the content of vitamin C, total carotenoids including ß-carotene, as well sugars in the fruits, both after the harvest and after the storage. After six months of the storage the rise of the content of dry matter, total carotenoids including ß-carotene, as well monosaccharides was noted, while the level of vitamin C, total sugar, and saccharose have been reduced.

The aim of the study was to determine the effect of drip irrigation on yielding of summer squash ‘White Bush’ grown under conditions of two localities: Lipnik near Stargard Szczeciński (soil of quality class IVb, and of good-rye-soil-complex) and Kruszyn Krajeński near Bydgoszcz (soil of quality class V, and of weak-rye-soil-complex). The study was designed as one-factorial trial: drip irrigation as the experimental factor was considered. Drip irrigation was conducted according to soil tensiometer indications (-0.04 MPa). Both, in Lipnik as well as in Kruszyn Krajeński, drip irrigation significantly increased marketable yield of summer squash ‘White Bush’. A higher rise in yields due to irrigation was obtained in Kruszyn Krajeński than in Lipnik. Mean marketable yield of summer squash fruits in Lipnik was higher than that obtained in Kruszyn Krajeński. Drip irrigation significantly increased the single fruit weight in relation to the control, in both crop localities. The system of drip irrigation significantly affected the number of fruits per plant. Summer squash plants grown in Lipnik produced higher number of fruits, than in Kruszyn Krajeński. In addition, essential influence of drip irrigation was affirmed on chemical composition of fruits, i.e. dry matter, vitamin C, monosaccharides, saccharose, content of total sugars and sum of carotenoids and ß-carotin.

A field experiment was carried out in two vegetation seasons in the years 2012 and 2013 on very light soil at Kruszyn Krajeński, in the vicinity of Bydgoszcz, Poland. The aim of the study was to characterize morphological achenes and determine the fertility potential and real of cup plant (Silphium perfoliatum L.) plants derived from micropropagation grown under irrigation. Low fertility real of cap plant resulted from the participation of infertile fruit-achenes it means devoid of the seeds. Due to the fact that this plant is entered on the list of invasive species, this property may be desirable during plantation establishment. As a result, the plant will not be so easy to penetrate into the ecosystem and will not pose a threat to native biodiversity.

Opis:
Cup plant (Silphium perfoliatum L.) is a tall, reaching up to 2.5 m, perennial plant that represents the Asteraceae family. Silphium perfoliatum L can be applied in medicine, animal feeding, and as a decorative, honey-producing and energy production plant which proves its multi-functional features. Sowing material currently available in Poland is insufficient, which justifies the present attempts at propagating these plants in in vitro cultures. Therefore, Silphium perfoliatum L. seed sterilization and micropropagation processes were studied under controlled conditions in in vitro cultures. Among the tested methods, ACE proved to be the most effective for sterilization. The apical parts of seedlings were used as explants; they were placed onto MS media with growth regulators added. 4 growth regulator concentration variants were applied. The highest percentage of explants with lateral shoots (41.7%) and callus (90.3%) was obtained on MS medium with 5 mg x dm-3 BAP + 1 mg × dm-3 NAA added. Shoots were isolated and transferred onto MS rooting medium without growth regulators. The rooted plants were transferred to the greenhouse and acclimatised to ex vitro conditions.
Rożnik przerośnięty jest wysoką, osiągającą 2,5 metra byliną, należącą do rodziny Asteraceae. Gatunek ten może być uprawiany jako roślina lecznicza, paszowa, ozdobna, energetyczna i miododajna. W związku z tym jest wykorzystywana w wielu gałęziach przemysłu. Jednakże występujące w Polsce źródła materiału siewnego nie zaspokajają rosnącego zainteresowania producentów tym gatunkiem. Z tego powodu podjęto badania nad procesem sterylizacji i mikrorozmnażania Silphium perfoliatum L. w warunkach kultur in vitro. Spośród zastosowanych metod sterylizacji nasion najbardziej skuteczną okazało się zastosowanie ACE. Jako eksplantatów do procesu mikropropagacji użyto wierzchołkowych części siewek, które wykładano na pożywkę MS modyfikowaną poprzez dodanie regulatorów wzrostu i rozwoju roślin. Zastosowano 4 warianty pożywki różniące się składem i koncentracją fitohormonów. Najwyższy procent eksplantatów z pąkami przybyszowymi (41.7%) i kalusem (90.3%) zaobserwowano na pożywce MS zawierającej 5 mg × dm-3 BAP + 1 mg × dm-3 NAA. Uzyskane pędy izolowano i ukorzeniano na pożywce MS bez regulatorów wzrostu i rozwoju a ukorzenione rośliny przenoszono do szklarni i aklimatyzowano do warunków ex vitro.

Opis:
The study of drip fertigation of winter squash ‘Gomez’ was conducted on the very light soil on the experimental field in Kruszyn Krajeński near Bydgoszcz in the years 2007 and 2008. The research was established as one-factorial, using the method of drawn blocks, in four replications. Drip fertigation (DF) as the liquid fertilization supplied nitrogen, potassium and phosphorus to the plants three times during growing season. As the control (DP), the drip irrigation combined with broadcast application was used. The potassium and phosphorus fertilization of control plots was applied before seed sawing. The nitrogen fertilization of control plots was provided in three single doses during vegetation. The liquid and powder fertilizations were performed at the same time. The complex fertilizer ‚Universol Blue’ (N:P:K = 18:11:18) was used. The dose of fertilizer was 3:2:3 (187.5:125:187.5 kg of NPK per ha). The irrigation was conducted using the drip line ‚T-Tape’. The liquid fertilizer was mixed by the ‚Dosatron’ dispenser. The irrigation started when the soil water pressure, measured with the tensiometers, was near - 0.04 MPa. In comparison to the control (powder fertilization), the drip fertigation (liquid fertilization) significantly increased marketable fruit yield, single fruit weight and fruit number. Most of the tested chemical components of ‘Gomez’ fruits (vitamin C, total sugar, monosaccharides, saccharose, total carotenoids and ß-carotin) were not significantly influenced by drip fertigation. However, the level of dry weight of winter squash ‘Gomez’ fruits was reduced by drip fertigation.

Opis:
This study examined the effect of fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark and mulching with fresh forest ectohumus on selected growth parameters in two – and three-year seedlings of common beech and the occurrence of mites (Acari) in soil. The experiment was carried out in 2009-2010 in the Białe Błota forest nursery (Bydgoszcz Forest District) on proper rusty soil. The entire area of the experiment was irrigated with a stationary sprinkler. The beech seedlings on the plots where compost had been used as fertiliser were significantly taller than those growing on the plots where mineral fertilisers had been applied. Mulching increased the height of the seedlings significantly only in the last, third year of the study. The tallest three-year-old seedlings were found on the plots in which both of the tested procedures had been carried out. Neither of the factors under study had a significant effect on the diameter of the root neck in the second year of the nursery cultivation, but they increased it significantly in the third year. Fertilisation with compost with an addition of pine-tree bark increased the number of leaves per plant and the leaf area in two – and three-year-old seedlings. A beneficial and significant effect of mulching on these parameters was found in the third year of cultivation. A significantly positive effect of mulching on the mite gathering density was recorded in the second year of the nursery cultivation. However, both of the experimental factors had a positive effect on the occurrence of those arthropods in the third year of the study. Oribatid mites were the most numerous mite order and they were found in the greatest density on plots where mulching had been applied. Fertilisation and mulching increased the Oribatida/Actinedida ratio, which may indicate an improvement of the biological balance in the soil environment.
