| 摘 要： | 通过盆栽试验研究了酸胁迫对番茄的生长、产量和品质影响.结果表明:在一定的酸胁迫强度下,番茄生长期明显延长;除5号处理(pH<3.5时)番茄的生长发育受到严重的抑制外,其余各处理植株的株高、茎叶干重和根长均高于对照植株;随着酸胁迫强度的加强,各处理植株的产量、成熟果率和维生素C含量随之下降,但番茄的可溶性糖量却增加;果实的总酸度与酸胁迫强度关系不大.

| Abstract: | A pot experiment was adopted to study the effect of acidic stress on the growth, yield and quality of tomato. The results showed that the acid stress result in the delay of tomato growth period. The height, stalkleaf-root dry weight and roots length were higher than CK when the degree of acid stress was accepted. The growth of tomato was strongly restrained as pH <3. 5. While the degree of acid stress increased, the yield and Vc content of tomato were decreased, but the soluble sugar content increased. The total acid content of tomato was irrelation with the degree of acid stress. |
