Description
Green building, forestry, agriculture of the Rostov region is in desperate need of resistant and long-lived samples of deciduous trees of the first grade. The main object of the search of promising forms of deciduous trees were artificial plantations of Quercus robur in the Botanical Garden of SFU. The research identified several of samples of Quercus robur, which are of economic interest. Based on ecological and biological properties and economic qualities, the most promising on was a sample of Quercus robur var. tardiflora, planted in 1888. This sample is less receptive to pests and diseases. It also has a high winter hardiness and drought resistance and significantly superior to similar samples of Quercus robur along longevity and has a high decorative effect. Dedicated sample of Quercus robur var. tardiflora, and his generation from seed is very different from other samples of the population by time of phenological phases. The all main henological phases of this sample occured later by on 10-15 days. The sample belongs to the group of plants of late phenological dates start and end of the growing season. The phenology of dedicated samples contributes to their high steadiness into regional climate. It propagates by sowing freshly harvested seeds. Phenological features of the selected sample might be inherited in the seminal generations

A NEW METHOD OF THE RAGWEED INHIBITION (AMBROSIA ARTEMI-SIIFOLIA L.) OF SOUTH RUSSIA
DescriptionAdventive weeds control using classical approach of biological protection against adventive species is not always satisfactory. A new method of the ragweed inhibition is developed that is based on shifting of the natural phenological stage of the phytophage growth. It makes possible to produce a large group of ragweed noctuidae under laboratory conditions on an artificial nutrient medium and to inundate weed infested areas with them by the time of the invader emergence

NEW α-GLUCOSIDASE INHIBITOR PRODUCER AND ITS CHARACTERISTICS
DescriptionThe data of the morphological, cultural, physiological and biochemical characterization of α-glucosidase inhibitor producer, isolated from soil sample by selective methodic is presented in this work. It is shown that on the set of listed attributes the culture can be referred to Kitasatoa genus. The 9th edition of “Key to the bacteria,” Bergey, Kitasatoa genus moved to a group of “Streptomyces and related genera” and transformed into the Streptomyces genus. In this case, strain 839 was named Streptomyces species, it was given the number 1328-D

NEW MEDIUM-RIPENING WATERMELON VARIETY YUBILYAR FOR PRODUCERS IN THE SOUTH OF RUSSIA
DescriptionAt present, the demand of producers and the market determine the model of future varieties. Task for breeders is to develop varieties having a set of economic and biological traits fitting into the model templates. The developed varieties and hybrids should ensure for climatic conditions of the Krasnodar region consistently high yields, better product quality and maximum efficiency of crop industry. As a result of breeding work there was developed a watermelon variety called Yubilyar, belonging to medium-ripening group, having high figures of economically valuable traits. The variety has resistance to unfavorable factors of growing conditions and stable yields. It is suitable for cultivation in rainfed areas and practically does not require protective measures against major diseases prevalent in the southern regions. Fruits are large, of wide elliptical shape, with bright crispy red flesh and a thin crust. Determined by stable fruiting under different weather conditions, friendly yield return, commercial fruits – up to 92%. Potential yield – up to 25 t/ha. Good stored for 40-50 days, suitable for transportation on a long distance. Passed preliminary tests on the fields in the Krasnodar, Rostov regions and the Republic of North Ossetia. According to results of evaluation from producers the variety meets requirements of the market and has a commercial appeal

NETSUKE AS A RESOURCE OF INFORMATION ABOUT SPECIES DIVERSITY OF LAGENARIA SICERARIA (MOLINA) STANDL
DescriptionIn the article, with a descriptive method and a method of analysis and synthesis, we have conducted a study of species diversity of Lagenaria on the basis of a miniature sculpture of netsuke. In Japan and China, in the period from the 17th to the 20th century, the most common was 9 species. The biological peculiarities of some rare species of lagenaria has been described

Description
One of the ways to save rare species of plants is to create models of natural communities on the grounds of the botanical gardens. In the Botanical Garden of Kuban State University we have created the model of forest communities with the participation of rare and endangered species, and we are still working on creating models of herbaceous communities. We have introduced 18 species of plants of the flora of the Krasnodar region in the forest community and more than 30 species in herbaceous community

Description
Along with traditional ways, the biotechnological methods become more significant in contribution to plant conservation in situ. The work is dedicated to elaboration and advancement of the method of isolated tissues and organs culture for conservation and reproduction of the badan, Bergenia crassifolia L., the rare species of Saxifrgaceae family. The conducted study yielded the regenerated plants of B. crassifolia from seeds. For the first time, we have performed conservation and reproduction of B. crassifolia in vitro under conditions of Yakutia
