Effect of Water Stress on Seed Germination and Seedling Growthin Maize

摘要

A laboratory experiment was conducted at Department of Plant Physiology,S.V.Agricultural college Tirupathi during kharif 2009-1 Oto study the effect of water stress on seed germination and seedling growth in maize genotypes .The results revealed thatas the water stress increases from -0.3 M.Pa to -1.5 M.Pa ,the percentage of germination , root, shoot length and seedling vigor index was decreased in all the genotypes . Among the maize genotypes tested ,AMH80 and AMH31 withstand the water stress evenupto -1.5 M.Pa followed by AMH5 ,AMH30,AMH27 and AMH5.
