摘要
为了探索促进盐肤木种子萌发的方法,研究了浓硫酸酸蚀处理对盐肤木种子萌发的促进作用。结果表明:未作酸蚀处理的种子硬实率高达85%,透水性差;浓硫酸处理提高种子的吸水性能和萌发率,并使种子发芽整齐一致。浓硫酸浸种30-105 min共6个处理,对种子萌发都有促进作用;其中以处理90-105 min的效果最好,发芽率可达70%,发芽势和生长势均高于其它处理。清水浸种48 h的对照种子萌发率最低。
t Rhus chinensis is an important tree species with high economic value. Its hard seed-shell significantly impedes its seeds germination. In order to explore the methods to promote the seeds" germination of Rhus chinensis ,researches were conducted on the effect of sulfuric acid treating to seeds' germination. Results indicated that: seeds without sulfuric acid treating had poor water permeability and the percentage of hard seeds was 85 %; sulfuric acid treating could increase seeds' water permeability, which was helpful for germination; germination rate of the seeds treated with sulfuric acid for 30 min,45 min, 60 min,75 min,90 min and 105 min were higher than CK (water soaking for 48 h); the optimum acid treatment was 90-105 min and the germination rate could reach about 70%,with maximum growth potential and germination capacity;CK had the lowest germination rate.
