Influence of density of saccharose and aucsins upon the process of formation of tubers of potato in crop of stolons in vitro

Abstract

The purpose. To determine the optimum technological methods influencing heightening intensity of tuber-formation of potato of early ripening variety Kobza in crop of stolons in vitro. Methods. Complex use of laboratory, mathematical-statistical, calculation-comparative methods and system analysis. Results. Experimental data are resulted on influence of density of saccharose and aucsins in nutrient medium on induction of tuber-formation at reproduction of potato in crop of stolons in vitro. Conclusions. The maximum productivity and reward payment of holdings at determination of optimum elements of technique of growing of microtubers of early ripening variety of potato Kobza in crop of stolons in vitro is generated at adding in nutrient medium of saccharose in dose of 80 g/l and kinetin in dose of 0,5 mg/l. Mass of average microtuber is 53,2 mg, amount of stolons which have organized microtubers – 87% at the cost price of microtuber 2,49 hrn and profitableness of production 141%.
