摘要
以豫麦49号和河农859为材料,研究了2个冬小麦品种在不同水分处理下,叶片内脯氨酸的积累状况。试验结果表明,水分胁迫下小麦体内脯氨酸含量增加。在短期水分胁迫下,不同小麦品种之间的脯氨酸积累量差异不大。但随着水分胁迫的延续和加剧,抗旱性较强的河农859脯氨酸积累量小于豫麦49号。
Under different water treatments, leaf free proline of two wheat cuhivars, Henong 859 and Yumai 49 were studied. The main results showed that under different extent of water stress leaf free proline increased. In short-term water stress, free proline accumulation of two cuhivars had little difference, but free proline accumulation of strong-drought cuhivar Henong 859, with continuing and intensing of water stress, was less than that of Yumai 49.
