浙贝母休眠解除后，鳞片近轴面表皮附近的几层细胞首先衰退，不久形成一条清晰的破碎细胞带。对这些首先衰退的细胞，在体眠解除前后进行了酸性磷酸酶细胞化学定位研究。休眠解除后细胞中酸性磷酸酶的活性明显高于休眠状态的细胞，淀粉粒、细胞核、线粒体和细胞壁上均有酸性磷酸酶的定位，而休眠状态的细胞中则很难发现酸性磷酸酶的定位，其活性较高表明这些细胞即将衰退。

Several layers of store cells near the adaxial cortex in scale of Fritillaria thunbergii Miq.degraded at the outset and forming a clear broken cell zone as the scale began to degrade after dormancy re lieving. A cytochemical study was carried out in these cells which would degrade at the outset to examine the changes of acid phosphatase activity before and after dormancy relieving. Acid phosphatase activity was sig nificantly higher in the dormancy relieving cells as compared to the dormant cells. Acid phosphatase was lo calized on starch grain, nucleus, mitochondrion and cell wall in the dormancy relieving cells, but the acid phosphatase localization was difficult to find in the dormant cells. High acid phosphatase activity in the dor mancy relieving cells indicates that these cells are going to degrade.
