不同层积处理对核桃种子发芽的影响

为了明确层积催芽时间对核桃发芽率的影响,以云新14#为研究对象进行了分析。结果表明,经过GA3150mg·L-1浸种8d后并进行层积35d种子萌动率最高,达到了82%;GA3150mg.L-1浸种催芽35d发芽情况最好,发芽率达到了94%,烂种率为6%,好种率为0。在生产中建议核桃层积催芽时间35d为宜。

Effects of Different Stratification on Seed Germination of Juglans regia

In order to determine the effect of stratification germination time on germination rate of Juglans regia , Juglans regia‘Yunxin 14#’were analyzed as the research object .Result shows that ：the seeds were soaked by GA3150 mg L-1 for 8 d and then were stratified for 35 d ,the rate of protocorm forming from seed are the highest , being 82% ;germination of seeds which were soaked by GA3150 mg L-1 for 35 d is the optimal ,germination rate be-ing 94% ,rotten seed rate being 6% ,good seed rate is 0 .The appropriate seed stratification time of walnut in produc-tion is 35 d .
