Introduction This study aimed to develop an optimal method for the production of fish hydrolysates and test their effectiveness as plant biostimulants under low-temperature growing conditions. Methods To obtain hydrolysates, waste a rainbow trout was used. Hydrolysates were prepared by enzymatic hydrolysis using entrails source enzymes. Differences in methods obtaining hydrolysates: samples І, ІІ, ІІІ, IV placed into water bath at +37°C, sample V left room temperature. Further nitric,...

The potential of using stems for the detection latent infection caused byRalstonia solanacearum (Rs) was studied. Forty plants each were collected from four farms with bacterial wilt incidence below 4% in two growing seasons (season A and season B 2005). tubers all selected including 10 cm lower collected. Samples taken to laboratory indexing against R. solanacearu (Rs) ELISA techniques. TheRs status composite samples determined then correlation coefficients computed....

New technologies of reintroduction plant species presuppose implementing both traditional and biotechnological methods for obtaining certain planting materials. However, plants cultivated in vitro exist specific conditions that lead to changes their structural functional state. This explains why it is hard them adapt ex situ conditions. Therefore, there a need the development multistage method cultivating would make influence on adaptive mechanism possible. One its stages optimization light...

This paper presents the comparative anatomical and morphological characteristics of plants two subgenera: <em>Haworthia</em> <em>Hexangularis</em>. The study revealed different strategies adaptation to arid conditions growth subgenera genus <em>Haworthia</em>. Plants subgenus adapted by increasing accumulation water, presence “windows”, a smaller stoma size, thinner outer wall epidermis cells. On other hand, <em>Hexangularis</em> reducing...

This paper presents a comparative study on the anatomy of Antarctic hairgrass (Deschampsia antarctica É. Desv.) from natural populations two distant maritime regions: Argentine Islands (Antarctic Peninsula region) and Point Thomas oasis (King George Island, South Shetland Islands).Comparison D. plants region originated seeds these cultivated in vitro also was made.Additionally anatomical features Deschampsia were compared with ones for caespitosa.The results our do not provide enough...

The water parameters of the leaves 9 species medium-sized trees (Aesculus pavia L., Aralia elata (Miq,) Seem., Broussonetia papyrifera (L.) L’Hér. ex Vent., Cercis canadensis Platycarya strobilacea Siebold & Zucc., Prunus dulcis (Mill.) D.A.Webb., Tetradium daniellii (Benn.) T.G. Hartley, Zizyphus jujuba Mill., Robinia viscosa Vent.) and 4 bushes (Cotinus coggygrya Scop., Cotinus Scop. ‘Royal Purple’, Berberis vulgaris L. ‘Atropurpurea’, Corylus maxima Mill. ‘Atropurpurea’) were...

The heat and drought resistance of plants depend on their anatomical biochemical features. In the present study, adaptive features three species wild rose (Rosaceae, Rosales) under short-term impact high-temperature stress have been characterized. Plants Rosa donetzica Dubovik, R. reversa Waldst. et Kit. spinosissima L. were exposed to a temperature 40 degrees C for 3 hours, following which peroxidase superoxide dismutase activity, photosynthetic pigments flavonoids’ content, lipid peroxide...

Abstract We studied the anatomical features of leaf structure Deschampsia antarctica É. Desv. (Poaceae) obtained from seeds collected different habitats maritime Antarctic. These plants have been maintained in culture vitro for more than 7 years. The include stable chromosome forms comprising diploids (2 n = 26), a diploid plant with B-chromosomes 26 + 0–3B), triploid rearranged morphology, and myxoploids ratios nondiploid cells root meristem. D. that were generally had similar nature. At...

The leaf anatomy of species the genus Rosa: R. donetzica, kokanica, roxburhii, rugosa, spinosissima was studied. It found that plants donetzica and kokanica have very low drought tolerance by anatomical structure. rugosin most xeromorphy features.

Peppermint grass, as a raw medicinal plant material, has great importance for the pharmaceutical industry. The influence of clonal micropropagation and chemotherapy been established in vitro on six breeds Ukrainian selection peppermint plants, particular sprouts’ conductive system structure tissue development, general biomass accumulation, vivo productivity breeds. important indices plants pharmacopeial plants. linear meter method, microscopic standard histochemical methods, statistical...

Plant adaptation to climate conditions of certain territories has emerged within the course evolution, shows at all organizational levels from morphological-anatomical biochemical and is embedded into plant genes.Survival plants in such as rapid temperature drops rises range 20 °C or more depends on their defense system's ability quickly respond stress, well plant's structural features.Therefore, our goal was analyze changes parameters under abrupt hyperthermia four species Crassula linne...

The impact of ultraviolet-B (UV-B) radiation on the culturable and unculturable bacterial communities were studied in field experiments using soybean plants grown under increased UV-B (UV-B+), negative control (UV-B-) solar UV-B. Sampling leaves exposed to was performed different developmental stages plant. data obtained demonstrate that did not alter community. In contrast, culture independent analysis revealed major differences between cultivars for stage development (cultivation time)...

B a c k g r o u n d . Dracocephalum moldavica L. is widely used in folk medicine many countries of the world due to its antispasmodic, antibacterial, analgesic, sedative and anti-inflammatory properties. D. essential oil often aromatherapy cosmetology. The use biotechnological methods for obtaining secondary plant metabolites has become increasingly popular recent years. On one hand, they serve as source substances beneficial pharmacology, while on other aseptic microclones medicinal plants...

B a c k g r o u n d . Global climate changes have negative impact on the life of native plants, reducing biodiversity. But other hand, increase in average annual temperature causes natural migration species and can make it possible to grow plants from warmer climatic zones, which are not yet widely cultivated Ukraine. One these is valuable medicinal highly decorative plant Nerium oleander L. The purpose this work was investigate resistance N. sharp hyperthermia hypothermia. obtained data be...

Dragon fruit (Hylocereus spp.) has emerged as a globally significant crop, valued for its distinctive appearance and nutritional profile. Native to Central America, this cactaceous vine adapted various tropical subtropical regions worldwide. The fruit's vibrant exterior houses white or red pulp studded with numerous edible seeds. Cultivation techniques have evolved optimize yield quality, vertical horizontal support systems specific nutrient management strategies being crucial successful...

Comparative analysis of the anatomical leaf structure 13 species genus Neoregelia has done. Species differ mostly by morphometric and quantitative parameters their leaves. Also trichomes N. lilliputiana pendula can be considered as markers a species. Two possible ways leaves adaptation to arid conditions on level, depending rosettes were found. 1) Thickening lamina, increasing percent water storage parenchyma, epidermal area, covered water-absorbing – in with small narrow rosettes. 2)...

The article represents a comparative anatomical analysis of leaves Rhododendron makinoi, R. degronianum, callimorphum and brachycarpum. It was shown that makinoi have most pronounced xerophytic features. degronianum are similar by morphometric characteristics, while brachycarpum well distinguishable. However, some quantitative parameters the leaf with statistically significant difference in been detected can be used as additional criteria for their taxonomic distinguishing. In general,...

It has been determined that under conditions of indoor and outdoor ponds the A.V. Fomin Botanical garden biomorphological peculiarities root system introduced plants Nymphaea alba L., Nuphar lutea (L.) Sm. N. pumila (Timm) DC did not change.
