摘要
研究了ＰＥＧ（聚乙二醇）对白菜种子春化的影响，结果表明，无论是ＰＥＧ４０００或ＰＥＧ６０００，均以２００ｇ／Ｌ浓度最适，不仅能有效地抑制低温春化处理过程中胚根或胚轴的伸长，而且也不影响种子春化的效果。种子春化处理后于室温下再催芽１天能显著地提高播种出苗率。ＰＥＧ对不同白菜种类的种子春化均有良好效果。
The effect of PEG on seed vernalization was studied in Brassica campestris.The best results were obtained from the treatment of PEG4000 and PEG6000 at 200g/L concentration,which restrained elongation of roots and hypocotyls effectively in the process of seed vernalization under 2～3℃,without reducing the effect of vernalization.Keeping vernalized seed one day at room temperature before sowing could increase the emergence rate significantly.PEG was found effective to different varieties of Brassica capmestris.
