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.

Phenological Phases

The study reports results of research carried out from April to October during 1988–2016 at the Botanical Garden of Petrozavodsk State University (South Karelia, middle taiga subzones). Three introduced species of the genus Larix (Larix sibirica Ledeb., L. leptolepis (Sieb. et Zucc.) Gord, and L. dahurica Turcz. ex Trautv.) were studied. The growth of shoots and needles in different species begins, reaches its culmination, and ends almost simultaneously, differing by no more than one week across the species. L. sibirica shows the highest growth rate. The timing of growth, culmination, and the dynamics of growth of shoots and needles are largely determined by variations in precipitation, temperature, and humidity. The direction and strength of such an effect may vary from year to year. The dates of phenological phases of the Larix species studied here are chiefly determined by the air temperature in the current growing season and the dates of formation of wintering buds in the previous growing season. Bud swelling and opening begins almost simultaneously in the studied species. Most of the other phenological phases begin and end earliest in L. sibirica and latest in L. leptolepis. All the studied species, primarily L. sibirica, are promising for residential landscaping and creation of artificial plant communities in Karelia

The paper presents the data of groundwater research of European cranberry productivity on mineral soils in the climatic conditions of the Udmurt Republic useful for industrial and private cultivation. Research aimed at developing technology of European cranberry cultivation on mineral soils, have scientific and practical perspective. Experience in direct rooting of European cranberry cuttings on mineral soils was conducted in 2010…2011 in the botanical garden of the Udmurt State University. As the planting material semilignified European cranberry cuttings were used harvested in the spring before the growing season in the Nizhny Novgorod region.

Russian Forest

Research of the flora of some areas of the Central Russian forest-steppe shows that a number of plants has deviations from the main species characteristics. The fact that there is a continuous series of variations from individual to species level in nature has long been known for a long time (Darwin, 1991). The reasons and results of this are very different and unpredictable. The ability of plants to change their phenotype is genetically determined. The scope of intraspecific differentiation depends on many external causes. The intraspecific potential of plants reveals itself when ecological situation and geographical fragmentation modify. In result, populations which significantly differ from the main genotype are formed. The impact of new environmental conditions is shown in the examples of Genista tinctoria L., Achillea millefolium L., Salvia pratensis L. The Trifolium lupinaster or Lupinaster pentaphyllus is an example of the introduction of geographically distant genetically stable races. Some species can be represented by different morphobiotypes. For example, erect (haying) and lying (pasture) forms of Lotus corniculatus, Medicago falcata, Astragalus onobrychis. There are some transitional forms. Populations of tall and low growing Anemone sylvestris were observed. A pronounced manifestation of intraspecific diversity is the polychrome of flowers. It was found in рlants from different families: species of iris, Schrenka tulip (Tulipa suaveolens), lily of the Saranka (Lilium pilosiusculum) and others. The collection of the botanical garden for over 20 years contains garden forms of plants of natural flora, which appeared due to spontaneous new formations. These are variegated forms of Aegopodium podagraria and Galeobdolon luteum. The results of the introduction of species and intraspecific diversity of rare and economically valuable plants in the Botanical garden of the Voronezh state University are presented.
