摘要
研究了番茄苗期耐盐性相关的指标,测定不同NaCl胁迫下不同耐盐性番茄品种苗期盐害指数、相对电导率、游离脯氨酸含量、过氧化物酶活性、过氧化氢酶活性、叶绿素含量、可溶性糖含量和丙二醛含量。结果表明:盐害指数、相对电导率、脯氨酸含量、过氧化物酶活性和过氧化氢酶活性可以作为番茄耐盐性筛选的指标。
The relative index of the salt-tolerance of tomato at seedling stage was studied.Salt injury index,relative rate of electrolytic,free praline content,POD activity,CAT activity,chlorophy concent,soluble suger concent,MDA concent,by using two different salt-tolerant tomato cultivars.The results indicated that salt injury index,relative rate of electrolytic,free praline content,POD activity,CAT activity,can be used as indexes to salt-tolerance of tomato cultivars.
