Effect of PEG(Polyethylene Glyco) on Seed Vernalization in Brassica campestris

doi:10.3321/j.issn:1000-7091.1998.01.027

Abstract

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
