摘要/Abstract

摘要： 以清江花魔芋（Amorphophallus Konjac）为材料,通过解剖学研究,揭示根状茎形成过程。结果表明,根状茎是由魔芋球茎上的不定芽萌发形成,形似棒状,先端有顶芽,其皮层、顶芽结构与魔芋球茎相似,根状茎的生长终止于植株衰老倒伏。魔芋的根状茎其实就是缩小版的球茎,但皮层比球茎厚,顶芽比球茎顶芽紧实。因此,根状茎在运输过程不易受损,魔芋种植新区根状茎是较好种源。

Abstract: Amorphophallus konjac of Qingjiang was taken as material, and the formation process of the rhizome was revealed through anatomical study. The results showed that the rhizome was formed by the germination of adventitious buds on the konjac bulb, which was like a rod, with terminal buds at the apex. The structure of cortex and terminal buds was similar to that of the konjac bulb. The growth of the rhizome ended with plant senescence. The rhizome of konjac was actually a reduced version of the bulb, but the cortex was thicker than the bulb and the terminal bud was tighter than the bulb. Therefore, the rhizome was not easy to be damaged during transportation. It was suggested that the rhizome should be used for the provenance of the newly developed konjac planting place.

Key words: Amorphophallus Konjac, rhizome, anatomical structure
