| 摘 要： | 以兰州百合鳞片为试材,利用秋水仙碱溶液对兰州百合进行了人工多倍体诱导.结果表明:秋水仙碱最佳处理浓度和最佳处理时间分别为0.l％、24 h,细胞诱变率达60％.对获得的兰州百合多倍体与二倍体叶片气孔大小及密度进行测定,通过方差分析,气孔大小及密度差异达到极显著水平.对兰州百合多倍体和二倍体植株根尖染色体计数发现,二倍体植株所有细胞染色体数为2n=2x=24,多倍体植株中有的细胞染色体数为2n=2x=24,而有些细胞染色体数为2n=4x=48.

| Abstract: | L.davidii var.unicolor(Hoog)Cotton scale was used as test material to inducted the polyploidy of L.davidii var.unicolorr(Hoog)Cotton using colchicine solution.The results showed that best concentration of colchcine was 0.1% in chromosome doubling induction of L.davidii var.unicolor(Hoog)Cotton.Under the concentration,the optimial time was 24 h,and the mutagenesis rate was 60%.Comparing the size and the number of stomata per unit leaf area of the leaf of diploid and the polyploidy plants,by the statistical a... |
