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).

The paper presents the results of a long-term (2001-2018) study of vegetative propagation methods of the Syringa L. genus varieties on the basis of the South Ural Botanical Garden Institute of the Ufa Federal Research Centre of Russian Academy of Sciences. The objective of the study was to determine the most effective and affordable ways of lilac varieties propagating in the climatic conditions of the Southern Urals, as well as to identify environmental factors affecting the effectiveness of vegetative propagation. Throughout the research period, such methods of vegetative propagation of lilac varieties as spring vaccinations, summer budding, propagation by aerial roots, green cuttings propagation were studied. As a result of the studies, it was found that the maximum quantity planting material is obtained when varieties are propagated by green cuttings using sand or a mixture of sand with perlite as a substrate. In the South Urals, greenhouses in the open ground for rooting lilac cuttings are practically unsuitable, because rooted cuttings die in them in winter or early spring. Therefore, in the climatic conditions of Bashkortostan, the rooting of lilac cuttings is desirable to be carried out in a sheltered greenhouse. With the help of spring vaccination, you can rejuvenate old vaccinated specimens, and summer budding can be used provided that the grafted plants provide a comfortable wintering, since early frosts characteristic of the Bashkir Urals lead to the death of green and not yet lignified shoots. The method of aerial roots can be considered acceptable and promising for the vegetative propagation of lilacs varieties.

The article describes new forms of apricot revealed in the sharply continental climate of the steppe zone of the southern Urals. The research was carried out in the period 2014-2020 on the basis of the Orenburg experimental station of horticulture and viticulture of the All-Russian Horticultural Institute for Breeding, Agrotechnology and Nursery. The experiment was conducted on annual seedlings in rain-fed conditions on a collection site in 2013, the layout of trees is 6×4 m. The soil of the experimental site and the adjacent massif is southern carbonate Chernozem, low-power, medium-loamy. According to productivity, fruit taste and winter hardiness (damage of 2 points), three forms of apricot SIZV-6-1, NO. 40, and D-36 were identified with the following characteristics: average fl owering period (from April 27 to May 1), the height is from 2 (D-36) to 3.5 (SI-ZV-6-1) meters, the yield is from 9.8 kg (form 40) to 15.7 kg per tree (form D-36). The revealed forms SI-ZV-6-1, No. 40 have a good, harmonious, sweet taste of fruits. The exception is the D-36 form, which has a sourness in the pulp. For all the time of research, the forms SI-SV-6-1, D-36, No. 40 were not aff ected by clasterosporium and moniliosis. The climatic conditions of the Orenburg region during the period of observation of phenological parameters were very diverse, which allowed us to give a comprehensive assessment of new forms of apricot. The information obtained during monitoring is new and can be used in breeding work.

Early Maturity

The article presents tests of natural creeping apple trees and natural dwarfs, carried out in the in the conditions of the Orenburg region. There were from 50 to 100 trees in the experiment in each variant. Vigorous standard plantations were used as control. The aim of the research was to test natural creeping apple trees, natural dwarfs against the background of standard varieties bred in the South Urals (Chelyabinsk), as well as to determine their prospects for intensive horticulture in the extreme conditions of the region. The preservation of plantings for all variants of the experiment for 20 years of research is high and amounted to 92-99 %, their condition was estimated at 4.5-5.0 points. The highest yield was noted for natural dwarfs (457.2 c/ha), the smallest yield was obtained on vigorous standard plantings (control) – 238.7 c/ha. Naturally creeping apple trees in terms of productivity were higher than control by an average of 25 %. Of the naturally creeping varieties, the most productive were the varieties Podsnezhnik (348.3 c/ha), Chudnoe (335.2 c/ha), the least productive were the varieties Plastun and Kovrovoe (255.1 and 262.5 c/ha, respectively). On the natural dwarfs, the most productive variety was the variety Brat Chudnogo (461.2 c/ha). In the control, the most productive varieties were the varieties Symbol (295.9 c/ha) and Nadezhda (270.5 c/ha), less productive were the varieties Pamyat Zhavoronkova and Fevralskoe (208.0 and 224.1 c/ha, respectively). Low-growing plantations, in particular layer and natural varieties of the Urals, are distinguished by their early maturity and, in general, higher productivity per unit area. The highest labor costs are accounted for by natural dwarfs (485.4 person-day/ha) and the lowest in vigorous plantings (317.4 person-day/ha). This has a positive eff ect on the profit and rentability of production.

The Impact

The impact of contrasting conditions of water availability on the size of the upper internodes in wheat varieties was studied under the conditions of the Orenburg steppe zone. It was noted, that less drought-resistant varieties formed a short upper internodes. We conducted a mathematical analysis of the relationship of productivity and length of ear-carrying internodes of spring soft wheat varieties of different ecological groups. It was established, that we can observe a gradual increase of grain productivity with increasing the length of the upper internodes in the studied range. As a result, the following varities were selected for inclusion into the hybridization: Logachevka, Tulaykovskaya steppe, Tulaykovskaya 1, Tulaykovskaya Belozernaya, Prokhorovka and Uchitel. They have the optimal settings for the presented feature. Using the selected varieties as parental forms can enhance the efficiency of wheat breeding programs for resistance to drought in the forest-steppe zone of the Southern Urals.

New Variant

The diversity of weed-field communities of sunflower crops within the forest-steppe zone of the Orenburg Region (Abdulinskiy, Matveevskiy, Oktyabrskiy, Aleksandrovskiy, Sharlykskiy districts) was studied. The communities in the system of ecological-floristic classification units are assigned to the new variant Orobanche cumana of the Amarantho blitoides - Lactucetum tataricae Khasanova et al. 2019. In the core of the cenoflora of communities juvenile weed species prevail. The most active of them are late spring annuals ( Amaranthus blitoides , Panicum miliaceum , Amaranthus retroflexus , Setaria viridis ) and early spring annuals ( Chenopodium album , Fallopia convolvulus , Camelina microcarpa ). Root perennials such as Lactuca tatarica , Convolvulus arvensis , Euphorbia virgata , Cirsium arvense have also a high proportion. A distinctive feature of the communities is the participation in their floristic composition of a dangerous quarantine species - Sunflower broomrape ( Orobanche cumana ). Modeling the area of the association under a moderate scenario of climate change shows that the distribution of communities by 2050 can cover almost the entire territory of the Cis-Urals (within the Republic of Bashkortostan). It is necessary to organize a monitoring system for the range of these communities in the Southern Urals.
