摘  要:
以小麦为试材,测定了2,4-D和二甲四氯对小麦种子芽长、根长和鲜重的抑制作用,结果表明,2,4-D 72 h处理对小麦种子芽长的EC50为492.53 mg/kg;2,4-D对小麦种子芽长、根长与鲜重间的抑制作用存在极显著差异;二甲四氯72 h处理对小麦种子芽长的EC50为798.28 mg/kg;同时其对小麦种子芽长、根长与鲜重间的抑制作用也存在极显著差异。

摘  要:
We measure the restrain activity of 2,4-D-ethylhexyl and MCPA to wheat bud、root and weigh based on wheat.The outcome show that the EC_(50) is 492.53?mg/kg of 2,4-D-ethylhexyl to wheat seed bud at 72?h.In addition,there are great diffence among them for F(155.7)> F0.01(8.7) when f=2.The outcome show that the EC_(50) is 798.28?mg/kg of MCPA to wheat seed bud at 72?h.In addition,there are great diffence among them for F(16.85)> F0.01(8.7) when f=2.
