Effect of Seed Soaking with Four Growth Regulators on Seed Germination and Seedling Growth of Maize

Effect of seed soaking with different growth regulators on seed germination and seedling growth of maize were studied by sand culture experiment to expand the application scope of four plant growth regulators and explore the application effect of them on seed treatment.The results showed that the four growth regulators could enhance germination index(GI) and vigor index(VI) of maize.The leaf area of maize treated by Haoxianshou was significantly increased,the root weight and number of roots treated by Tianda-2116 were obviously increased,CCC had great effect on root length.The chlorophyll content in leaf treated by Luyuan was increased by 38.9% compared with that treated by clean water.
