摘　　要：以小麦为试验材料,测定了2,4-D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对小麦种子芽长的EC50为492.53 mg/L;2,4-D对小麦种子芽长、根长和鲜重的抑制作用间存在0.01水平显著差异。The inhibition effect of 2,4-D-ethylhexyl on wheat bud,root and fresh weight.Tile results showed that the ECho was 492.53 mg/L of 2,4-Dethylhexyl to wheat seed bud at 72 h. In addition, there were great diffence among wheat bud, root and fresh weight.
