GRAPEVINE PLANT REGENERATION FROM CELL SUSPENSIONS AND INFLORESCENCE FORMATION IN VITRO UNDER THE INFLUENCE OF DIFFERENT VITAMIN AND MINERAL ELEMENT LEVELS IN NUTRIENT MEDIA

abstract 0500906010 issue 50 pp. 112 – 130 29.06.2009 ru 2865
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.

THE MATHEMATICAL MODEL OF ECOLOGICAL SITUATION ON THE RICE IRRIGATION SYSTEM

abstract 0440810003 issue 44 pp. 48 – 64 25.12.2008 ru 2881
Solving of problems of the influence of irrigation on ecological situation and creation of optimum land-reclamation conditions are impassible without using of the mathematical modeling methods. The work provides the idea of solving of the land-reclamations problems with the using of systematic-cognitive analysis.

GENERAL CHARACTERISTIC OF ABUNDANCE CHANGE IN AGRO ECOSISTEM OF ORGANIC GARDEN IN EXPERIMENTAL FARM “KUBAN”, KU-BAN STATE AGRARIAN UNIVERSITY

abstract 0510907017 issue 51 pp. 376 – 382 28.09.2009 ru 2890
As for beneficial fauna, the most number of parasitic hymenoptera is noticed in organic orchards. The least quantity of parasitic hymenoptera can be met in conventional orchards. The characteristic feature of arthropods in conventional orchards in 2008 was the frequent occurrence and rather big number of acariphages (ladybirds of Stethorus family). The occurrence of the considerable quantity of predatory bug Campilomma and the bugs of Orius family was registered. All the enumerated species attack phytophagous mites. With the assumption of phytophagous mites population increase in organic orchards, the increase in Stetorus specimen was registered. Acariphages in ecological orchards occurred rarely. So we can suggest that predacious insect species – Stetorus, Campilomma, Orius –can serve as a certain indicator showing one or another population density of phytophagous mites in apple-tree orchards.
