- 摘要:
- 以商陆为试材,对商陆幼苗进行秋水仙素诱导多倍体试验。结果表明:0.2%秋水仙素诱变48 h效果最好,与对照相比,变异株茎粗壮,叶宽、叶厚较对照分别增加40.15%和33.25%;气孔纵横径较对照分别增加30.25%和60.82%,气孔密度增加150%;压片法对变异植株和对照植株的根尖有丝分裂分别进行染色体鉴定,证明变异株为多倍体。
- Abstract:
- Taking Phytolacca acinosa Roxb.as material,Phytolacca acinosa Roxb.seedlings were treated with different concentrations of colchicines solution,polyploid induction test was conducted.The results showed that the best treatment was using 0.2% colchicines solution and 48 hours.Compared with the control,the stems of variant plants became more dwarf and stronger,leaf width was increased by 40.15% and leaf thickness was increased by 33.25%.Length and width of stomata was increased by 30.25% and 60.82% respectively,the density of stomata was increased by 150%;the variant plants were polyploid by tabletting method of mutant plants and control of the plant root mitotic chromosome identification respectively.
