BIOLOGY OF SEED GERMINATION OF SOME SPECIES OF FAM. ROSACEAE JUSS
DescriptionWe have studied the germination and the nature of germination of seeds of 20 species of FAM. Rosaceae. A wide range of germination characterizes their seeds: rapid, slow, with very poor or no germination. Laboratory germination of seeds stored at room temperature for 6-7 months have 80-100% - 8 species, 66-77% - 3, 1-9% - 4 species and 5 species did not germinate at room temperature, they need special conditions for germination

Description
The article gives the results of the study of an effect of mechanochemical powder of wood green of Abies (MPA) on potato morphogenesis in vitro. The study involved the hormone-free nutrient mediums (MS, ½ B5, ½ LS) for growing microcuttings from preliminary obtained aseptic plants. Plant morphogenesis was observed on the 15th and 30th days. At that, the number of developed shoots, plant height, leaves number, rhizogenesis rates, root number and length were estimated. MPA appeared to have the regulatory effect on morphogenesis of potato microcuttings. Based on mineral composition of the nutrient agar medium for potato microcuttings growing, MPA at 100 mg/l concentration induced root development (½ B5 medium), reduced height of shoots (MS medium), while the number of leaf blades was not affected

INTRODUCTION OF IRIDACEAE IN CENTRAL YAKUTIA
DescriptionThe results of introduction test of species and cultivars variety of irises in the Central Yakutia are described in this article. Climatic conditions of the introduction region are extreme and they are strong restrictive factor at introduction to the culture of many other species and cultivar of decorative plants. The condition of plants after rewintering was estimated on a 4-mark scale. Total number of the plants which were lost in the first winter (0 points) is 126 species and cultivars that is 60,9%. For 01.06.2015 year a collection of irises in Yakutia makes 40 exemplar of species (22 species) and 31 exemplar of cultivars (30 cultivars), 7 species of them are successfully adapted (3 points) (Iris biglumis Vahl., I. bloudowii Ledeb., I. potaninii Maxim., I. scariosa Willd., I. setosa Pallas ex Link., I. tigridia Bunge, Pardanthopsis dichotoma (Pallas) Lenz). The listed species annually plentifully blossom, form seeds and intensive form escapes. Four species Iris biglumis, I. scariosa, I. bloudowii, Pardanthopsis dichotoma are form stable self-seedling

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

DescriptionFeeding lactating dairy cows of the Simmental breed using the collection of herbs with Тhyмus bituminosus Klok, Achillea millefolium L., Polygonum aviculare L., Galium verum L, Chamerion angustifolium L., Sanguisórba officinális, Stellaria media L. and Amaranthus retraflexus L. contributed to a better digestibility and nutrient utilization of diets. A high level of digestibility by cows experimental compared to the control group is set with respect to the dry and organic matter of 2.0% and a crude protein 1.4 %. When using the collection of herbs, there was an increase in the antioxidant status of erythrocyte cells in blood of dairy cows as expressed in the increasing content of low molecular weight antioxidants in blood cells by 1.4 times in reducing the intensity of lipid peroxidation of erythrocyte membranes in 1,2 times, in comparison with the control values. The use of the collection of herbal increases milk yield of cows of the experimental group by 7.4 %, increases by the 16.2 % yield of milk fat and the protein content of 10.7 % in milk of dairy cows compared to the control group
