Reductional Division and Flowering Hafit of Aneurolepidium Chinense 羊草花序减数分裂及开花规律的研究
Chromosome reductional grouping happened more frequently in polyploid cells. 染色体减数分组较多发生于多倍体细胞中。
One type was somatic chromosome reductional grouping, in which the chromosomes in a cell either separated into two groups, or separated into more than two groups at prophase or metaphase. 一种是体细胞染色体减数分组,其中,处于前期或中期的细胞染色体分为2个或2个以上的组。
The authors believe that the method has following advantages: convenient procedure, better reductional quality, elimination of transposition stress, exact effect of fixation and excellent clinical results. 认为本术式操作方便,易于掌握,复位质量保证,移位应力减小,固定效果确切,临床疗效满意。
