摘要
以不同耐盐性苹果属植物珠眉海棠、小金海棠和山定子的幼苗为试材,测定了各部位的可溶性糖含量,NaCl胁迫下苹果属植物可溶性糖含量的增加均大于等渗PEG处理,苹果属植物的耐盐性与其主根、侧根、幼叶和成熟叶可溶性糖的累积量呈负相关性。
Mains seedlings M. zumi,M. xiaojinensis and M. baccatawith different salt -tolerance were used as experimental materials. Soluble sugar content of different parts was determined. The increase of soluble sugar content in NaCl stress was more than that in iso - osmotic PEG treatment. Salt - tolerance of Maius seedlings showed negative correlation with soluble sugar accumulation in main roots,lateral roots,young leaves and mature leaves.
