Two similar and concurrent experiments were carried out in the Agricultural Research Center of Islamic Azad University, Kermanshah Branch and Agricultural Research Center of Islamabad during 2016-2017. The experiments were performed in a split-plot format in a randomized complete-block design based on 3 replications. The main plots were assigned to 4 different regimes of irrigation: (I1) full irrigation during the growth period followed by 50% of the soil moisture depletion; (I2) water deficit stress from the start of the flowering stage) Z61 (to the milking stage (Z77) associated with irrigation after 80% of the soil moisture depletion; (I3) water deficit stress from the beginning of the flowering stage(Z61) to the ripening stage (Z93) followed by irrigation after 80% of the soil moisture depletion; and (I4) water deficit stress from the start of the milking stage (Z77) to the ripening stage (Z93) followed by irrigation after 80% of the soil moisture depletion. The 3 cultivars of C1 (Sirvan), C2 (Pishtaz), and C3 (Marv dasht) were treated using the allocated sub-plots. The results revealed that by increasing the drought stress intensities on the wheat cultivars, Grain Yield (GY), Relative Water Content (RWC), and Total Chlorophyll Content (TCC) were decreased except for Proline Content (PC). Sirvan cultivar subjected to the treatment of drought stress (I3) led to the highest reduction in RWC and TCC compared to the control treatment (I1). The results of this study indicated that the wheat cultivars of Islamabad Agricultural Research Center had higher GY (5129 kg.h-1), TCC (58 mg. g-1 fr.wt.), and RWC (92%) values than those of the Agricultural Research Center of Islamic Azad University, Kermanshah branch.

Phaseolus vulgaris (haricot beans) is one of the most important pulse crops with high nutritive and strategic value. The goal of our study was to define changes in morphological elements playing the crucial role in crop productivity, namely, in the yield components (number of the pods and seeds per plant) depending on the cultivation technology treatments. We studied effects of moldboard plowing depth, mineral fertilizers application doses and inter-row spacing on the above-mentioned haricot beans yield components in conditions of the Steppe zone in field trials. The trials were carried out at the irrigated lands represented by the dark-chestnut solonets soil, in four replications by using the split plot design method with partial randomization during the period of 2014–2016. The data obtained in the trials were processed by using ANOVA and correlation analysis. Results of the study showed significant increase in the number of pods and seeds per plant of haricot beans with decrease of inter-row spacing width and higher mineral fertilizers application doses. Depth of plowing had no significant effect on the number of pods, and slightly effected the number of seeds per plant of haricot beans. The maximum number of pods (17.2) and seeds (71.7) per plant of the crop was provided by the agrotechnical complex with moldboard plowing at the depth of 28–30 cm, mineral fertilizers application dose of N90P90, and inter-row spacing of 15 cm.

Field and experimental studies of morphological and anatomical leaf parameters of Phragmites australis showed the structural adaptation of these plants to growth under different water supply regimes. The anatomical structure of the leaves of common reed, which grew in shallow water and dry land in the Venice channel of the Dnipro river in Kyiv, was studied with the light microscopy. The obtained results suggest that the anatomical structure and type of mesophyll cells are stable parameters for this species, while the size both of the leaf blade and its cells can be considered as adaptive and labile features varying depending on the conditions of water supply.

Erysimum croceum is a rare endemic species listed in the Red Book of Kazakhstan. In 2015–2017 we studied three populations of this species on the territory of the Ile-Alatau National Park (Trans-Ili Alatau, Northern Tian-Shan). As a result of the inventory of sampling plots, we estimated the elevation range occupied by the species and identified age structure and population density. Our results confirmed earlier reports of low population counts of E. croceum. We also studied biometric characteristics of virginal and generative individuals of E. croceum from different populations, and measured parameters of their seeds. The morphometric parameters were highly variable across the studied populations. The only exception was the morphometric parameters of the seeds, which had low or very low variability. We conclude that these parameters are the most stable characteristics of the species. The results of the study can contribute to our understanding of population structure and dynamics of E. croceum and assist in developing effective conservation strategies for this species.

The anatomical properties of leaf, stem, and root of Epidendrum radicans Pav. ex Lindl., belonging to the subfamily Epidendroideae (Orchidaceae) were investigated for adaptations to stressed habitats. The anatomical investigation revealed that leaves of E. radicans have a thick cuticle (3–4 µm) and paracytic type of stomata. Foliar epidermal cells are conical on the adaxial surface and rectangular in the abaxial surface, distinct hypodermis absent, and uniseriate fiber bundles are arranged in both sides of the leaves. The foliar mesophyll is homogenous and starch grains and raphides present. The leaf sheath covering the stem have cuticle restricted to the outer surface and air spaces are present. The stem has a cuticulerized uniseriate epidermis and a uniseriate hypodermis. The cortex and a parenchymatous ground tissue of the stem are separated by a layer of sclerenchymatous band. Vascular bundles are collateral and their size generally increases from the periphery towards the center. A sclerenchymatous patch covers the phloem pole, whereas the xylem is covered by thin-walled parenchymatous cells. The roots possess Epidendrum-type velamen. Cover cells present. Uniseriate dimorphic exodermis consists of U-thickened long cells and thin-walled passage cells. The endodermal cells O-thickened, pericycle sclerenchymatous, xylem 10–14 arched. The pith is sclerenchymatous, but parenchymatous at the center. The anatomical examination of E. radicans revealed adaptations to moisture stress conditions like thick cuticle covering the leaves and stem, water storage cells, multilayered velamen and dimorphic exodermis.

The effect of UV-B radiation on the growth and development of pea plants was studied. Pea is a self-pollinating plant with unlimited branching and short vegetative period. The number of flowers and pods per plant is limited by the conditions of vegetation. It is established that after irradiation of seedlings in doses from 2 to 15 kJ/m2 shoot growth decreased. Dose of 2 kJ/m2 inhibited growth, dry mass accumulation of shoots, formation of flowers and pods. The dose of 4 kJ/m2 activated increasing quantity of flowers and pods. Further increasing the dose of UV-B irradiation suppressed growth and development of pea plants. UV-B irradiation in a wide range of doses caused growth inhibition of pea plants. Pea plants are convenient object for investigation of UV-B radiation effects.

In vitro seeding constitutes an indispensable tool for propagation of the main commercial species of orchids. This study aimed to analyze the in vitro development of Catasetum fimbriatum under different concentrations of jasmonic acid in Murashige & Skoog culture medium compound of ½ macronutrients. After 180 days of cultivation, concentration of 0.25 and 0.50 μL • L-1 caused a significant increase in number of roots and leaves. The concentration of 1.00 μL • L-1 showed the best result for the length of longest root and largest leaf, the total length of seedling, and the total fresh and dry masses. Nevertheless, the use of this plant regulator on in vitro culture media still requires further investigations to determine the optimal concentration in order to obtain desirable phytotechnical characteristics in different orchid species.

The knowledge of plants interactions is used for their better protection and cultivation. Theaim of this study was to determine the influence of alcoholic extracts from the leaves of thecommon sunflower (Helianthus annuus) on selected physiological parameters of plants ofwhite mustard (Sinapis alba ‘Barka’). The seeds germination, the growth, the fresh and drymasses of plants grown from seeds and germinated on the sunflower extracts and plantswatered by H. annuus extracts during the growth phase were studied. In the growth phase, thefresh masses of all organs were increased on 5 % extract, however significantly decreasedon 10 % extract. The dry mass of S. alba was not significantly changed. In the germinationphase, much less changes of these parameters were revealed. In general, extracts fromH. annuus leaves inhibited germination of S. alba seeds, but stimulated growth of plants incase of application of 5 % concentrations during the germination phase and inhibited theirgrowth in case of application of 10 % concentrations during the growth phase.

The paper describes morphology of erems, laboratory germination capacity and germination rate of the of Hyssopus officinalis plants grown under conditions of Zhytomyr Polissya. The research revealed insignificant differences between investigated hyssop varieties with respect to external structure, color, mass, and biometric indices of their erems. The mean mass index of 1000 erems for H. officialis ‘Markiz’ was 1.09 g, for ‘Atlant’ – 1.13 g, and for ‘Vodograj’ – 1.10 g. The length of erems was slightly higher (2.91 ± 0.06 mm) in ‘Atlant’, while the width and thickness of erems (1.09 ± 0.05 and 0.84 ± 0.03 mm respectively) were highest in ‘Vodograj’. Laboratory germination capacity of H. officialis erems showed tendency to decrease during a storage period of 5 years, however the germination rate was stable for the first 4 years. ‘Vodograj’ demonstrated the highest germination rate (84 %) and germination capacity (98.5 %) in general.
