| 摘 要： | 对抗ＨＹＰ和抗盐的葡萄变异细胞系进行了比较分析，结果表明抗ＨＹＰ变异细胞的脯氨酸含量是抗盐变异系的２．８６倍。在盐胁迫下，抗ＨＹＰ变异系吸收的Ｋ＾＋和Ｎａ＾＋含量高于抗盐变异系，但二者的Ｋ＾＋／Ｎａ＾＋比值相近。实验表明在筛选葡萄抗逆变异系过程中，以ＨＹＰ作为选择压力更为适合。

| Abstract: | Comparative study was made between the two variant cell lines resistant to hydroxyproline(RH)and resistant to salt(RS)in vitis vinifera.The results showed that the proline content in RH was 2.86 times as much as the content in RS;the K and Na content absorbed in RH was more than that in RS,but the K /Na values in two lines were very close;the response of cell line to NaCl and PEG was also compared between RH and RS,RH exhibited much greater tolerance to the tested stress condition than RS.Experiments showed the hydroxyproline was more suit than NaCl as a selection pressure in isolating variant cell line of grapvine. |
