The article presents the results of studying the diversity of pear rootstock forms in terms of yield and seed productivity. The research was carried out at the experimental sites of the Orenburg Experimental Station of Horticulture and Viticulture of AllRussian Horticultural Institute for Breeding, Agrotechnology and Nursery and the Botanical Garden of the Orenburg State University in 2017-2019, in typical soil and climatic conditions of the Orenburg city. The purpose of the study is to identify pear rootstock forms characterized by high yield and stable seed productivity for use in the future as a seed rootstock. During the research, 15 pear accessions were studied; the planting scheme was 6x4 m. As a result of research, it was found that the rootstock form Temno-zelenaya is characterized by a high yield (40 kg/tree). High seed productivity of more than 6 seeds in one fruit was observed in samples: Vernaya (6.0-6.5 pcs.), SK-1, SK-3 (6.1-7.8 pcs.), SK-2 (7.0-7.5 pcs.), Chang Bai Li (7.4-7.7 pcs.), Semennaya 214 (7.5-7.8 pcs.). It was revealed that the Xiao he Bai Li variety is characterized by the maximum weight of 1000 seeds (65.2 g). Analysis of accessions by seed yield established that a consistently high yield is observed in the varieties Chang Bai Li (2.5-4.2 %), Vernaya (3.96-4.18 %) and forms SK-1 (2.0-3.25%), SK-2 (2.25-2.75 %), SK-3 (1.43-4.0 %). Pear rootstock forms Chang Bai Li, Vernaya, Semennaya 214, SK-1, SK-2, SK-3 were identifi ed, which can be recommended for production testing as seed pear rootstocks for the conditions of the steppe zone of the Southern Urals.

Research 2019-2020 in the conditions of the forest-steppe zone of the Chelyabinsk region showed that the effect of glauconite on the yield and seed productivity of potatoes largely depends on the variety. The effect of glauconite (in doses from 10 to 40 t / ha) on the yield of tubers was proportional to the duration of the growing season of the varieties. The highest yield gains from glauconite were observed in the mid-ripening variety Tarasov – 4.05–4.62 t/ha, then in the medium-early variety Nevsky – 3.26–3.63 t/ha, and the smallest – were in the early variety Rosara – 1.95–2.26 t/ha. Whereas the effect of glauconite on the seed productivity of varieties had the opposite pattern: the greatest increase was observed in early-maturing varieties (Rozara – 1.30–1.56 times, Nevsky – 1.30–1.61 times), and the smallest – in the mid-season variety Tarasov (1.17–1.25 times).

In five species of Trollius L., seed production of fruits was studied, plants being grown in culture in the forest steppe zone in Western Siberia. 2 species representing Chiastocheta genus were identified as specialized pollinators (Diptera, Anthomyiidae). Those insects pollinate the flowers and damage the seeds of three globeflower species: T. apertus, T. europaeus T. asiaticus. The flower season of other two species (T. chinensis and T. ledebourii) starts later and the plants can’t be exposed to invasion, as Chiastocheta flies are at their larval stage yet. Pollination of these species is performed by non-specialized agents. The lowest rate of seed production realization of about 20% is registered in T. europaeus, while in T. ledebourii it is the highest comprising 71%. We consider the flies of Chiastocheta genus as an important part of the complex of factors lowering seed productivity in Trollius and their relationship as parasitism. Thus, in West Siberia for Trollius seed production increase, measures intended to reduce Chiastocheta abundance will be useful.

First Time

In the forest-steppe zone of Western Siberia, a comparative study of seed productivity, flowering features, fruit and seed morphology, pollen fertilization ability was conducted for the first time in representatives of the Hosta Tratt genus: H. decorata, H. sieboldiana, H. lancifolia, H. albomarginata, H. crispula, H. kikutii, H. montana, H. rectifolia, H. undulata and varieties Golden Tiara, Night before Christmas, and Stiletto. It is noted that the reproductive potential and fertility of pollen in 9 species and 3 varieties of host have intraspecific and varietal specificity and are associated with seasonal weather conditions. The results of free pollination of the host were studied. It was found that fruit formation within a single generative shoot is heterogeneous, with the exception of the species H. decorata. The coefficient of productivity of species is 16—93%, varieties 12.5—36.4%. Morphometric indicators of length of generative shoots, fruits and seeds are presented. It is shown that the fruit is a freely opening loculicidal tricuspid capsule. Seeds are linear to oval in shape. It was revealed that with high viability of pollen grains (46—82.6%) in H. albomarginata, H. rectifolia, H. sieboldiana, the productivity coefficient is 2—3.8 times lower than in H. decorata. The flowers are characterized by geitonogamy with the phenomenon of peterandre, chasmogamous pollination and flowering in acropetal direction. H. decorata has a high adaptive advantage of seed productivity. The studied species and varieties consistently pass all the phenophases of development and are characterized by vitality. The growing season from spring growth to fruiting in Novosibirsk is 98—112 days. The reproductive capabilities of the host during introduction in the forest-steppe zone of Western Siberia are realized partly due to seed reproduction and are distinguished by species and variability.

Abstract Grindelia squarrosa (Pursh) Dunal. (Asteraceae) is a species with high invasiveness capacity in Ukraine, especially in the Steppe zone. The first data on the finding of escaped plants in Europe were recorded in the 40’s of the last century. There were three naturalization centres in Ukraine, from where the species began to spread. In the secondary range in Ukraine, G. squarrosa is characterized by high levels of seed productivity and germination, variable modes of dispersal, wide ecological and coenotic amplitudes and CSR-strategy. The trend continues with the spread of the species in western, north-western and northern directions, and today more than 300 localities confirming this trend are already known. In the past 20 years, 92 new localities have been recorded. G. squarrosa is a transformer, widespread in the southern regions of the Steppe zone. As a result, new plant communities are formed. In general, this species is recorded in communities of five vegetation classes. In terms of ecological indicators, the optimum of the species is in the Steppe zone. It can be predicted that, due to the potential ability of the species to adapt and under the influence of climatic change, there is a higher probability that the species will spread in the future in northern and western directions. The condition for such an expansion is disturbance of meadow-steppe fringe xeromesic communities, with decreased coenotic competition.

Currently, the main priorities in agricultural production are ecologization, rational use of natural resources, resource-conservation and economic practicability. Therefore, biotechnologies for growing agricultural crop develop. The article presents the results of effectiveness of pre-sowing treatment with polyfunctional microbial preparations compared to the use of mineral fertilizer Ammophos in growing Cіcer arіetіnum L. in the steppe zone of the Crimea on non-irrigated southern Chernozem in 2015-2017. Weather conditions during the growing season and treatment with microbial preparations, as well as the use of mineral fertilizers, affected seed productivity of chickpeas in the time of research. On average, for three years, bacterization with Rhizobofit, Cyano-rhizobial consortium and complex Rhizobofit + Phosfoenterin + Biopolicyd significantly increased 1000 seeds weight and seed yield by 16.67 g (6.7%) and 0.15 t/ha (10.8%); 27.27 g (9.8%) and 0.1 t/ha (7.2%); 14.14 g (5.5%) and 0.22 n/ha (15.1%), respectively, compared to the Ammophos application in dose N30P30 (Duncan’s test p < 0,000121). These preparations are recommended for biologised agrotechnology for growing chickpea in the steppe zone of the Crimea and obtaining ecologically safe production.
