PREDOMINANT WEEDS AND THEIR INJURIOUSNESS IN SUNFLOWER CROPS
06.00.00 Agricultural sciences
Description
Competitive relations between various kinds of weeds in sunflower crop and influence of connatural factors on its constipation are considered. Specific weight of each kind of a weed and its change throughout a vegetative period, and also influence of gramineous weeds on efficiency of breeds and hybrids is defined. The economic threshold of injuriousness of gramineous weeds in sunflower crops is defined

USE OF DIFFERENT BIOTYPES OF VARIETIES-POLLINATORS IN SELECTION OF SUN FLOWERS
06.00.00 Agricultural sciences
Description
Possibility of getting of qualitatively new selection material of sunflower – complex hybrids by means of use as paternal form of separately taken biotypes of varieties-pollinators was shown in the work. Getting of highly productive large-fruited complex sunflower hybrids on the base of pollination of sterile simple hybrid Kubansky 93 by different biotypes of variety Lakomka on the example of getting of complex hybrid Kubansky 93x Lakomka 1 was considered in the article. Received selection material of sunflower is main for creation of new highly productive, resistant to unfavorable factors of environment of competitive varieties and hybrids of sunflower.

Description
The Mavrostifo – Greece aboriginal variety. It is belong to the group of varieties convar. pontica subconvar. balcanica Negr. The time of production period is 156-165 days. The variety of medium height. The degree of ripening of vine is higher. The yield is higher. The average mass of bunch is 360 g. It has higher drought-resistance and middle steadiness for mushrooms diseases. The leave is large, black-green, the middle dissection, five lobes (the lobes are recovered), from bottom side with a lot of hairs. There are two blossoms on the 3 and 4 nodes. The flower is hemofroditus. The bunch is low or big, long, conical-winged, density. The berry is average, round, black-blue. The pulp is juicy, with tasty variety after taste. There are two-three seeds in berry. The sugariness is higher. The variety is useful for preparing higher quality intensive colored red wines of different categories from southern zones of viticulture with warm and dry climate.

Description
Effects of different levels of vitamins (thiamine, pyridoxine and nicotinic acid) and macro-elements (MS, NN and PG) on development of globular, heart- and torpedo-stage embryos and plantlets with green cotyledons and on shoot production from them were studied in grapevine interspecific hybrids: cvs. ‘Bianca’, ‘Podarok Magaracha’ and ‘Intervitis Magaracha’. Pro-embryogenic calli were derived from petiole explants on solid full-strength NN medium supplemented with different levels of 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzyladenine (BA) for each cultivar and used to initiate cell suspensions in liquid NN medium supplemented with 1 mg L-1 2,4-D and 0.2 mg L-1 BA. The following formulations of media were optimal for different stages of somatic embryogenesis and for plantlets with green cotyledons development: liquid NN medium supplemented with 0.5 mg L-1 BA for globular embryo formation; liquid HTE medium (with PG macro-elements, thiamine and pyridoxine at 5 mg L-1 each and 0.5 mg L-1 nicotinic acid): supplemented with 0.2 mg L-1 BA for heart-stage embryo development, supplemented with 0.1 mg L-1 indole-3-acetic acid (IAA) and 30 mg L-1 sodium humate for torpedo-stage embryo development and supplemented with 0.5 mg L-1 gibberellic acid (GA3) for the growth of plantlets with green cotyledons. Solid MS medium modified by the addition of nicotinic acid, pyridoxine and p-aminobenzoic acid (PAB) at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.5 mg L-1 BA was best efficient for shoot production from plantlets. Inflorescence formation in regenerated plants of cv. ‘Podarok Magaracha’ grown on solid hormone-free PG medium was induced by addition of nicotinic acid, pyridoxine and PAB at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.2 mg L-1 BA into liquid modified HTE medium for growth of plantlets with green cotyledons and into solid modified MS medium for shoot production from them.
