Ca^(2+)等外界因素对紫鸭跖草体细胞晶体含量的影响

Ca 2+ AND OTHER FACTORS EFFECT ON THE CRYSTALS INCOMMELINA COMMUNIS L. CELLS

用离体培养法培养紫鸭跖草，发现在一定浓度范围内（０．２５％～２％），随着Ｃａ２＋浓度的增加，其体细胞中晶体量及含晶细胞数增加；当Ｃａ２＋超过２％时，晶体量不再增加，甚至减少；晶体量同时受温度、光照、水质、时间、其它金属离子及ｐＨ等有关因素的影响。

When Commelina communis L. was cultured in vitro, it was found that,from 0.25% to 2%,the number of crystals in the cells would add up withthe going up of Ca 2+ concentrations, and however when Ca 2+ was beyond 2%,the crystals would no more go up and would more go down.In addtion,thenumber of crystals in the cells was inffected by temperature, light,water, reaction time, antagonistic ions and pH and so on.
