【摘要】 用从多花水仙鳞茎分泌物中分离出的一种生物碱Narciclasine(NCS)处理不同植物的愈伤组织可使其细胞核发生明显的形态变化.可使烟草和小麦的核液泡变小甚至消失、核物质浓缩、核质比减小.在NCS处理的细胞中均观察到了无丝分裂的发生,提示NCS对于细胞的作用方式可能与秋水仙素有所不同.更多还原

【Abstract】 Narciclasine is a kind of Amaryllidaceae alkaloid, which is isolated from bulbs of Narcissus tazetta L. The callis of tobacco and wheat were incubated in 10^-6 g/L or 10^-4 g/L for 1～3 days. （Obvious） changes in the neucleus were observed. For example, volume of vacuole was decreased, the （nuclear）-cytoplasmic ratio lessened, and nuclear matrix condensed. Sometimes amitsis was observed. Such strong inhibitory effect cannot be obtained in the treatment with colchicines of groovy concentration （10 g/L, W/V）. The results obtained in our experiment and reported by other researchers indicate that NCS may be used not only as a new plant growth regulator but also as a new anti-cancer medicine.更多还原
