NaCl胁迫对不同番茄品种幼苗及果实的影响

Effects of NaCl stress on seedlings growth,fruit quality and yield of different tomato varieties

研究了NaCl胁迫对5个不同番茄品种的幼苗生长、果实可溶性糖含量及产量的影响.结果表明,盐胁迫抑制了番茄幼苗植株的生长,降低了幼苗的单株鲜重,减少了果实产量,但可以提高果实可溶性糖含量.同一盐胁迫条件下,不同番茄品种性状存在显著差异.

The effects of NaCl stress on seedlings growth,fruit soluble sugar content and yield of five tomato varieties were studied.The results showed that NaCl stress inhibited seedlings growth and single plant fresh weight,as well as decreased fruit yield,however,the soluble sugar content was raised.There was a significant variation of characteristic among different tomato cultivars under similar NaCl stress.
