铜胁迫对辣椒种子发芽及其幼苗生长的影响

Effect of Copper Stress on Seed Germination and Seedling Growth of Pepper

以"新育8819"线椒种子为试材,研究了不同浓度CuSO4溶液浸种对辣椒种子萌发及幼苗生长的影响。结果表明:CuSO4浓度为0～100mg/L时,能在一定程度上增加株高、单株鲜重、根长、叶绿素含量以及过氧化物酶(POD)的活性。随着CuSO4浓度增大,对辣椒种子萌发、辣椒幼苗的株高、单株鲜重、根长、叶绿素含量、过氧化物酶(POD)抑制作用也越大。

Taking pepper variety ＇ Xinyu 8819＇ as experimental material, the effects of different concentrations of CuSO4 soaking on the germination of pepper seed and growth of seedling were studied. The results showed that when CuSO4 concentration was lower than 0-100 nag/L, it could increase plant height, fresh weight and root length, chlorophyll content and POD activity. With the increasing of CuSO4 concentration, the inhibitory effect on the germination of pepper seed was stronger, and plant height, fresh weight and root length, chlorophyll content and POD activity decreased obviously.
