The article presents the results of the reproductive biology study, gives fruit set and seed production data as well as some morphological characteristics of fruits and seeds of the genus Paeonia species, introduced in the Central Botanical Garden of NAS of Belarus.

The results of the comparative analysis in the biennial cycle averaged observations coefficients of variation of 15 quantitative characteristics of the biochemical composition of the fruit of the dogwood, mountain ash and chokeberry. It is shown that all three species of lower variability in taxonomic ranks characterized by content of dry fruit and pectin, and most in the content of anthocyanins and total bioflavonoids.

Cultural-morphological and physiological-biochemical properties of new fungal strain Phallus impudicus 5 were studied. Optimization of nutrient medium composition and cultural conditions enabled to increase biomass yield by 1.3 times, contents of endopolysaccharides by 1.5 times and exopolysaccharides by 1.7 times. The mycelium comprised 50-54 % of total carbohydrates, 13-14 % of endopolysaccharides, 7-11 % of chitin, 20-21 % of crude protein, 12-13% of true protein, 2-2.3 % of lipids, 0.46-0.82 % of total phenolic compounds. Comparative analysis of chemical composition of Ph. impudicus mycelium and fruit bodies was performed.

The blueberry flowers are collected in simple brakteoznye, racemose inflorescence on average from 6 for Putte variety to 10 - for Spartan and Toro, sometimes there are single. Calyx with 5 teeth. Whisk-white, greenish-white or white with a pinkish tinge, oblong-shaped urceolate 7.9-11.4 mm length and 4.4-8.8 mm in diameter, usually with 5 free limb at the throat of the flower. For Chandler, Spartan and Sunrise varieties whisk has nearly spherical shape, and for Denise Blue and Reka varieties -extended. Androecium often includes 10 stamens. The gynoecium is represented by a single complex pestle 7.6-10.0 mm length.

M) and characterized. Enhanced glucose oxidase production (by 12.5-88.2 %) in the course of submerged fermentation was recorded in 4 P. adametzii strains: 2.19; 5.16; 5.17; 5.18. P. adametzii A 5.17 was chosen as the promising glucose oxidase producer distinguished by maximum values of enzyme generation and productive capacity of the mycelium.

The results of the study on the morphological features of spontaneous somatic mutations of three abies spieces are discussed in this article. The authors demonstrate the perspectives of using them to produce new resistant ornamental garden forms.

Historical aspects of the formation of the Belarusian flowerbeds were highlighted. Based on the collection of ornamental annuals plants of CBG NAS Belarus is proposed perspective assortment for the Belarusian flowerbed. Analysis of some decorative and biometric characteristics of the proposed range is presented in this article.

The article presents the results of the preparation of 67 varieties of Hyacinthus х hybridus Hort. as the most effective method of increasing the coefficient of vegetative propagation. It is revealed that depending on the groups varied from 7 to 59 units.

, the maximum efficiency of electron transfer in the FS, a minimum amount of phenolic compounds and high anti-radical activity.

The paper contains the results of investigation of earthworm distribution and their species diversity depending on the bio-geocenose type. The common species for all biogecenoses is A. caliginosa.

When growing Spirulina platensis under the LED light sources a reduction in the level of FeSOD gene expression has been showed. Photosynthetic activation, which leads to increased productivity of the algae processes in LED lighting, can also assumes to cause an increase in oxidative processes in cells of Spirulina platensis. Oxidative effects can increase while enhancing of intensity of illumination of these sources of photosynthetically active light. Taking to account reducing of FeSOD gene expression, algae stability to stress will reduce, and as a consequence it will lead to a decrease culture productivity or its destruction.

The results of 30 year research on plant breeding optimization with the use of computer tools are stated. Mainly theoretical aspects that were tested on the real and effective barley breeding process are presented. Logically reasonable steps for creating breeding information technology are provided. They include improving input data collection, output (calculated) information production and management solutions for all plant breeding stages.

It was shown that in the period 2007 and 2009-2012 ratio of basic mating types A1:A2 for 367 isolates of Phytophthora infestans was close to 1:1 with a slight predominance of A2, and taking into account a rare type A1A2 also marked in this work total ratio A1:A2: A1A2 was 153 (41.7 %): 208 (56.7 %):6 (1.6 %). Both main types of sex were marked during all years of collecting in all regions of the country in most fields, indicating that they were fairly uniformly distributed in space and time. These data are an important indicator and the main condition for the possibility of occurrence of sexual reproduction in natural populations of P. infestans. It is noted significant differences in the ratios A1:A2 for potatoes and tomatoes isolates of pathogen. In the case of potato A2 was predominant type, as for tomato - A1 type. Furthermore it was revealed that the ratio of mating types within one field, and within the season vary substantially depending on the time of collection.

The results of researches on biological and economic efficiency of the insecticide Grinda, SP against onion fly in common onion are stated. It is determined that the modern plant protection against onion fly by the insecticide Grinda, SP has provided with the common onion yield increase for 30.7 %.

This article studied features microsporogenesis 2 varieties of plum a cultural: Asaloda and Cometa Kubanskaya possessing varying fertilizing capacity.

The capacity of surfactants producers Acinetobacter calcoaceticus IMV B-7241, Rhodococcus erythropolis IMV Ac-5017 and Nocardia vaccinii IMV B-7405 to synthesize exocellular phytohormones was established. The concentration of auxin (84-140 цЛ), cytokinins (3.5-364 цЛ) and abscisic acid (0.9-3.6 цЛ) depend on the nature of carbon source in the cultivation medium of strains and method of isolation (before or after extraction of the surfactant).

Buffalograss (Bouteloua dactyloides) is a native grass of the Great Plains but is a species of concern in Minnesota because it is restricted to only a few sites in the southwestern corner of Minnesota where it is found on rock outcrops. Conservation efforts at the Minnesota Landscape Arboretum have been initiated to investigate the most threatened of these sites and to collect seed for seed banking. Due to its low-growth habit and drought and heat tolerance, buffalograss has recently become popular as a low-maintenance turfgrass. To promote this grass for drier sites in Minnesota, demonstration plots were planted at the Minnesota Landscape Arboretum. Additionally a comparison trial was started at the Arboretum in 2015 to compare the improved turftype buffalograss to the Minnesota native wild type.

Endangered species lists continue to grow, even though efforts to conserve species have increased. More needs to be done to preserve individual species. Public gardens, as locations that connect people to plants, are important and underutilized resources that are only relatively recent recruits to the effort to preserve endangered species. With growing facilities and horticultural knowledge at ready access, public gardens are excellent locations for ex situ conservation efforts. The University of Minnesota Landscape Arboretum developed a Plant Conservation program in 2013 that will strive to preserve endangered species through both long-term genetic preservation and research to aid in species conservation and restoration.

The search and monitoring of cenopopulation Iris aphylla L. (Iridaceae) in the Bryansk region were carried out in 20102015. The asessement of the number of the cenopopulations was done. The basic indicators of productivity for generative individuals were marked. Test tube plants of Iris aphylla, well propagated in culture in vitro were obtained. Explants of rhizome and seeds were cultivated on the MS medium with the concentration of BAP 0,05 mg/l. The way thidiazuron affects the multiplication ratio was studied.
