摘要:
为探讨植物碳代谢对土壤干旱的响应,以湖北麦冬为供试材料,采用盆栽试验,研究持续干旱20 d对叶片内叶绿素含量、核酮糖-1,5-二磷酸羧化/加氧酶(Rubisco)活力、非结构性碳(可溶性糖和淀粉)及脯氨酸含量的影响。结果表明,当干旱持续10 d时,光合色素含量和Rubisco活力均显著降低(P<0.05),可溶性糖和脯氨酸含量显著升高(P<0.05),与此同时,淀粉含量显著降低(P<0.05)。表明在干旱条件下湖北麦冬对叶片内的碳水化合物进行了重新分配和利用,将有限的碳更多地分配给可溶性糖和脯氨酸等富碳分子,以提高细胞的渗透调节能力,从而抵御干旱胁迫。但随着干旱时间的进一步延长,碳代谢及渗透调节能力均降低。
