摘　　要：通过对花魔芋及多叶花魔芋生物学性状进行比较分析,发现多叶花魔芋与花魔芋在叶生物量、叶柄颜色、株高、叶柄长度、叶柄直径及小裂叶数上存在显著差异.多叶花魔芋的第二叶光合总色素显著高于花魔芋.多叶花魔芋的单株球茎鲜重比花魔芋提高了17.8%,而球茎葡甘聚糖含量、水分含量无明显差异.该结果可为进一步深入研究多叶花魔芋提供参考.The comparative study on the biological characters of konjac and multi-leaf konjac was conducted in the study.The results show that there were significant differences in leaf biomass,petiole color,height,petiole length,petiole diameter and number of leaves between multi-leaf konjac and konjac.The second of multi-leaf konjac photosynthetic pigments were significantly higher than konjac;The Corm fresh weight of Multi-leaf konjac increased by 17.8%,and the glucomannan,moisture content had no significant difference between them.This results can provide reference for further study of multi-leaf konjac.
