摘要:
细根周转对森林生态系统碳地下分配和养分循环具有重要影响,而衰老是细根周转过程中最重要的阶段。根据“源-汇”理论,细根衰老受碳向细根分配的影响。为此,该研究通过控制水曲柳(Fraxinus mandshurica)苗木向根系的碳分配的遮荫处理试验,采用树木生理分析技术,重点研究了在光合产物供应停止情况下水曲柳幼苗根系的生理变化(即根尖、1级根到3级根的细胞活力、可溶性糖含量、可溶性蛋白含量和膜透性的变化)。目的是从生理水平上证实:1)碳分配对细根衰老产生怎样的影响;2)细根衰老的顺序是否与分支顺序相反。实验结果表明,遮荫处理使细根活力、可溶性糖含量、可溶性蛋白含量显著降低和膜透性增大,导致细根出现明显衰老。从根系顶端向基部随着根序增加,细胞活力、可溶性糖含量和可溶性蛋白含量提高,膜透性降低,从生理水平上表明细根衰老具有逐渐变化的顺序性,并且这种顺序性与根发育的顺序性相反。
