铝与除草剂草甘膦的交互作用对青菜的毒理作用

     

摘要

The interaction toxicity of aluminum and glyphosate to greengrocery germination, sprout length and root elongation was studied. The results indicated that aluminum and glyphosate significantly affected growth of greengrocery. Low concentration of aluminum decreased the glyphosate's toxicity to germination, sprout length and root elongation of greengrocery to some extent,while low concentration of glyphosate could reduce aluminum's toxicity to sprout length. The toxicity of mixture of aluminum and glyphosate could be found as joint action at high concentration, and the strongest toxicity was showed when the highest aluminum and glyphosate concentration were added.%以青菜为供试材料,研究铝与除草荆草甘膦的交互作用时青菜种子的发芽势以及发芽后青菜种子的根长和芽长的影响.结果表明,铝与草甘膦对青菜表现比较明显的生长抑制作用,低浓度的铝能在一定程度上缓解草甘膦对青菜种子的发芽势、根长和芽长的抑制作用,而低浓度的草甘膦在一定程度上降低了铝对青菜种子发芽势和芽长的毒性.在高浓度下,两者均表现出对青菜种子的发芽势、根长和芽长的联合毒性,并在最高处理浓度时,毒性最强.
