摘要: 利用四因素五水平正交试验设计,研究PEG浓度、硼浓度、钼浓度及浸种时间对大粒蚕豆发芽能力的影响,结果表明钼酸铵24mgL-1、硼酸钠4mgL-1、PEG 5%、浸种时间16h或钼酸铵8mgL-1、硼酸钠8mgL-1、PEG5%、浸种时间24h两组浸种处理效果最佳,发芽率均达100%。PEG和浸种处理时间对蚕豆浸种的发芽影响最大,硼和钼微量元素浸种对蚕豆发芽率影响不显著。试验结果表明,大粒蚕豆浸种的PEG最佳浓度为5%,最佳浸种时间为16h。

Abstract: Germination rate of the big broad beans soaked under different conditions was studied for optimization.A 4-factor-5-level orthogonal design on concentrations of polyethylene glycol(PEG),boron and molybdenum,and bean soaking time was used for the experiment.The results showed that either by soaking the seeds in a solution containing(a) 24 mgL-1 ammonium molybdate+4 mgL-1 sodium borate+5% PEG for 16 hours,or(b) 8 mgL-1 ammonium molybdate+8 mgL-1 sodium borate+5% PEG for 24 hours,100% germination could be obtained.PEG and soaking time appeared to have the most significant effect on the germination of the big broad beans,and none with the presence of boron or molybdenum.Thus,using 5% PEG to soak the bean seeds for 16 hours was recommended for promoting the germination.
