| 摘 要： | 以菘蓝为材料,研究了在培养基中添加不同浓度聚乙烯醇对菘蓝组培苗玻璃化现象的发生影响。结果表明,随聚乙烯醇浓度的升高,组培苗玻璃化率降低,但浓度过高会抑制组培苗的生长,对叶片的分化抑制作用也较大。此外试验还发现适宜浓度的聚乙烯醇(1.5g/L)可起到促进组培苗生根的效果。

| Abstract: | Taking woad as the maternal plant,the influence of different concentration of polyvinyl alcohol on vitrification in tissue of woad were studied.The results showed that vitrification was inhabited by the supplement of the polyvinyl alcohol in the mdium.But higher concentration of polyvinyl alcohol suppressed the growth of the tissue culture,and the polarization in lamina is relatively great.It is also found that suitable concentration of polyvinyl alcohol(1.5g/L)could advance taking root. |
