PEG-6000引发对苦荞种子萌发及幼苗牛长的影响
Effect of PEG-6000 Priming on Seed Germination and Seedling Growth of Tartary Buckwheat
摘要
Abstract
To study the polyethylene glycol （PEG-6000） solution priming on the germination of buckwheat seeds,the PEG-6000 concentration of 10% ,20% ,25% ,30% and 12 h,24 h,36 h of priming time were adopted to study on Seed I of Sichuan buckwheat respectively to determine the seed gemaination rate, germ- inative force, shoot fresh weight, shoot dry weight, bud length, and to calculate the simplified vigor index. The results show that：concentration of 25 % PEG-6000 solution can effectively improve the germination rate of buckwheat seeds, which is significantly higher than those of other concentrations. At this concentration, the rate of 24 h of priming time is significantly higher than those of priming times; different priming times can improve the germination rate of buckwheat seeds, germinating ability of the buckwheat seed under 24 h is more than that of 12 h and 36 h, but the difference is not statistically significant.关键词
