| 摘 要： | 选取生长势一致的龙葵幼苗进行5个施药剂量梯度的处理,测定其叶片中叶绿素、可溶性糖、丙二醛含量.结果表明,随着草甘膦剂量的加大龙葵幼苗叶绿素a含量、叶绿素b含量和叶绿素总量与对照相比均显著减少;在施药后第4天,750 g/667m2剂量下处理的幼苗可溶性糖含量比对照增加了244%,低剂量草甘膦(15 g/667m2)处理龙葵幼苗,可溶性糖含量变化不显著;经高剂量草甘膦处理后的幼苗丙二醛含量也显著增加.因此,农业生产中推荐使用750 g/667m2剂量的草甘膦防治龙葵.

| Abstract: | In order to provide theoretical basis for the resistance to glyphosate during seedling stage of Solanum nigrum L.,the effect of the different spraying dose gradients of glyphosate on the content of chlorophyll,soluble sugar and malondialdehyde of Solanum nigrum L.leaves were studied.The results showed that,the content of chlorophyll a,chlorophyll b and total chlorophyll of plants treated with glyphosate reduced significantly comparing to the control plants.The soluble sugar in the leaves of the plants were ... |
