Growth and physiological performance of primed rice genotypes under pot culture

Abstract

The present investigation was carried out at green house, department of crop physiology, S.V Agricultural College, Tirupati to know the effect of seed priming on growth and physiological parameters of dry direct sown rice (Oryza sativa L.) under pot culture. The experiment was conducted in completely randomized design with 20 combinations (4 varieties and 5 treatments). Varieties screened are MTU 1010, JGL 20171, NLR33671 and MTU 1112, whereas treatments are Control (Hydropriming/Water soaking), 1000 PPM GA3 and combination of both gibberillic acid and KNO3 treatments i.e.; GA3 (200PPM, 500PPM, 1000PPM + KNO3@3%), in order to know the effect of growth and physiological performance of seed primed rice genotypes under pot culture. Various physiological observations like plant height, No of leaves, Leaf area, Total dry matter, Days to 50% flowering and Yield attributes was measured in all four genotypes.
