摘　　要：在豇豆第一对真叶充分平展后,分别剪去植株的1/2片、1片、2×1/2片、1+1/2片、2片真叶,结果显示,豇豆植株的生育期、植物学性状、豆荚性状以及总产量都将受到影响,并且随着损伤程度的加大,影响逐渐变大。试验表明,第一对真叶在豇豆生长发育过程中有很重要的作用。After full extension of the first pair of true leaves,0,1/2,1,2 ×1/2,1 ＋1/2,2 pieces of them was cut to inves-tigate the effect of damage of the first pair of true leaves on growth and development at late stage of cowpea. The results showed that the growth stages,botany characters,pod properties and total yield of cowpea plant were affected,and the influ-ence to cowpea gradually became larger with the increase of damage degree. The test showed that the first pair of true leav-es play a very important role in growth and development of cowpea.
