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天能显着地提高播种出苗率。PEG对不同白菜种类的种子春化均有良好效果。

Abstract: 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.

Key words: PEG, Seed vernalization, Brassica campestris
