摘  要:
通过对喀斯特石质山地月月青无性系种群的根系形态和生物量分配特征的研究 ,结果表明 ,月月青无性系种群的根系极发达且不对称 ,根冠比大 ,根系穿透能力强。地下与地上部分生物量比值接近 1∶1,根系生物量中主根生物量所占比值最高 ,其次为根蔸 ,侧根最小 ,此生物量分配特点是月月青长期适应喀斯特石质山地严酷生境的结果 ,对维持其无性生殖、种群的稳定和发展起到重要的作用。

摘  要:
The root morphology and biomass allocation characters of Itea ilicifolia in Karst Stone Mountain were studied, the results showed that root of Itea ilicifolia was well developed and not symmetry, the ratio of root to crown was large, the root had great ability of passing through soil and parent material layer.The ratio of aboveground to underground of biomass was close to 1∶1.The biomass of root was the biggest at the arial root, then at the root collar and lateral root.
