摘要
在人工配制的具有不同pH梯度的苏打盐碱土上栽培番茄,对番茄果实的风味和营养品质分别进行了测定分析,研究了苏打盐碱胁迫对番茄果实品质的影响。结果表明:番茄具有较强的耐碱性,可在土壤pH9.34以下的苏打盐碱地上生长并结实。脯氨酸含量测定结果表明,随着土壤盐分含量增加?
The effect of saline-sodic stress on quality of tomato （ Lycopersion esculentum Mill） fruit was studied by culturing tomato in various salinity and pH soil mixed with non-sodic soil and sodic soil. The results showed that tomato was tolerant to alkali stress, it could grow and fruit in sodic soil with pH less than 9.34. Under saline-sodic stress, tomato fresh weight per fruit decreased by 15% - 41% and organic acid content increased by 3% - 13%, but tomato fruit soluble sugar content increased by 13% - 37%, ratio of sugar and acid improved by 0.2 - 3.1. Light saline-sodic stress increased the content of vitamin C, but severe saline-sodic stress decreased the content of vitamin C in tomato fruit.
