摘要
通过不同浓度的Cr6+对玉米萌发影响的测试结果表明 ,当Cr6+浓度为 5mg/L时 ,Cr6+可以促进玉米种子的萌发 ,提高玉米的发芽势和发芽率 ,促进玉米芽与幼根的生长 ;而高浓度的Cr6+不利于玉米萌发和生长。
In present paper the influences of Cr 6+ at different concentrations on the germination of maize were studied. It is shown that Cr 6+ could raise germination percentage, viability, index of seed vigor,the bud growth and root growth when Cr 6+ level was 5mg/L. High level Cr 6+ was harmful to germination and growth of maize. Cr 6+ has bigger inhibition influence on root growth of maizw than on its bud.
