多倍体细胞

家蚕多倍体细胞遗传学研究

Study on the Polyploid Cytogenetics in Silkworm , Bombyx Mori

染色体减数分组较多发生于多倍体细胞中。

Chromosome reductional grouping happened more frequently in polyploid cells .

以0.06%的秋水仙素处理72h可以得到较高的多倍体细胞诱导率，而且不至于对愈伤组织产生严重的伤害。

0.06 % colchicines with 72h treatment was effective on polyploidy induction . The inducing rate was high , and callus was harmed gently .

此外，还出现多倍体细胞群体。

In addition , a polyploid cell population appeared .

双核、多倍体细胞、小叶及结节周围的肝细胞易呈明显阳性，一种小而核深染的多角细胞常呈强阳性。

A kind of thin , polygonal liver cells with one or two round or oval and deeply stained nuclei frequently stained strongly positive .

继代培养和离体保存1a后愈伤组织的倍性组成保持了相对稳定性，这是由于多倍体变异细胞在不断产生的同时也通过程序性死亡途径不断被淘汰。

However , the relative genetic stability of chromosome ploidy was maintained during subculture and in vitro conservation , which resulted from the disappearing of variant cells by programmed cell death .
