Cadmium (Cd) is one of the most toxic heavy metal elements to the environment, which seriously threatens the safe production of food crops. In this study, we identified a novel function of the cytomembrane TaSFT2L protein in wheat (

The results of study of the population ontogenetic structure of the main forest-forming species (Pinus sylvestris, Quercus robur, Acer platanoides, Betula pendula, Populus tremula) of the Left Bank Polissia of Ukraine are presented. The study covered plant communities, which are the most common and typical in the region. They are represented by four formations of forest vegetation, viz. Pineta sylvestris, Querceta roboris, Betuleta pendulae, Populeta tremulae, and belonged to 24 syntaxes in the rank of association groups and up to 42 syn-taxons in the rank of associations. The study was based on the use of geobotanical and population-ontogenetic approaches and methods. It was established that in the forests of the region, the most part of main forest-forming species populations have left-sided ontogenetic spectrum. Invasive populations are the predominant category. Only in the populations of the species involved in the formation of the second and especially the first tier of stands reveals the centred and bimodal spectra. In these species, the frequency of normal population occurrence increased, but their proportion was within 6.7–13.6%. No regressive populations were found in the main forest-forming species of the region. It was fixed that the ontogenetic spectra of the most of populations of the studied species were incomplete due to the absence of plants of some ontogenetic states. It was noted that the individual extinction of the young generation before they reached the generative ontogenetic state, was the clear evidence of significant disturbance in the region forests of the generation variability in forest-forming species. The limited representation of windfall microsite complexes in the composition of the forest plant communities of the Left-Bank Polissia of Ukraine as well as gaps enough in size to ensure successful undergrowth development and formation of a continuous flow of generations is one of the consequences of long-term man-made impact on these forests.

The problems of introduction into practice of intensive oats cultivation technologies in the North-Eastern part of the Forest-Steppe of Ukraine have been considered. The oats plant yield capacity depends on mineral nutrition optimization. It was defined that hulless oat cultivars have more expressed response level of yield capacity on pre-sowing treatment with composition of Diazophyt and Microhumin bacterial fertilizers, that allows to reach closer to the level of hulled oat yield. The highest crop yield (for all cultivars) provided by combination of pre-sowing treatment with Diazophyt + Microhumin composition and application of N60P60K60 with foliar nutrition in tillering and panicle forming phase by Nutrivant Plus (2 kg/ha) + Urea (46.2%) 30 kg/ha. The maximum additional yield was fixed in Salomon cultivar with presowing Diazophyt + Microhumin treatment (+0.73-0.75 t/ha). Vegetative development and yield capacity of oats cultivars in the experiment revealed the group reaction dynamics on pre-sowing treatment, doses and ways of fertilizer application under conditions of the North-Eastern Forest-Steppe of Ukraine. The oat cultivar reaction specifies on optimization of zonal growing technologies for hulled and hulless cultivars. Thus, it is considered the possibility of increasing crop yield by improving of cultivation technology separately in the context of hulless and hulled groups of cultivars.
