摘要: 瑞香试管苗的玻璃化受到细胞分裂素浓度和茎尖外植体大小的影响,细胞分裂素浓度越高,茎尖外植体越小,产生的玻璃苗越多。玻璃苗与正常试管苗的茎尖在形态结构上有明明显差别,主要表现为顶端分生组织原体原套结构异常和细胞的明显液泡化。

Abstract: The vitrification of Daphne plantlets in vitro was affected by the size of the tip explant and the concentrations of cytokinin in the media, much more vitreous plantlets were induced when smaller shoot tip explant and higher concentrations of cytokinin were used. The zonal structure of shoot apex of vitreous plantlets appeared different from normal potted plants and normal plantlets in mainly aberration occurring in corpus and tunica.
