Influence of storey of cuttings of test glass plants and nutrient medium upon induction of formation of tubers of potato in vitro of grades of different groups of ripeness

Abstract

The purpose. To determine optimum regime for formation of tubers of grades of potato in vitro of different groups of ripeness depending on storey of cuttings of test glass plants and content of nutrient medium. Methods. Complex use of laboratory, mathematical-and-statistical, calculation-and-comparative methods and systems analysis. Results. Experimental data about influence of storey of cuttings of test glass plants and content of nutrient medium on induction of formation of tubers are resulted at reproduction of different by group of ripeness grades of potato in crop in vitro. Conclusions. The best productivity indexes are gained at growing microtubers of middle-ripening grade of potato Yavir on nutrient medium of Institute of irrigation farming agriculture of NAAS at plants from 1–  3-rd storey of a cutting. So, the mass of average microtuber has made 502 mg, mass of microtubers for 1 plant — 509,8 mg. Yield of microtubers in mass more than 350 mg — 84,7%, intensity of formation of tubers made 101,5%.
