摘要
对优良水土保持灌木-荆条的种子形态、吸水特性及萌芽特性进行了研究,结果表明:荆条种子球形,千粒重(9.78±0.05)g,种子吸水约需要4 h就能达到水分饱和状态。荆条经赤霉素处理后,发芽整齐,其中200 mg/kg的赤霉素溶液对提高种子发芽率效果最好,平均发芽率为69.3%。
Vitex negundo is one of plants that has excellent soil and water conservation function, the water-sopping characteristic and germination characteristic of seeds were studied. The results showed that seeds of Vitex negundo were roundness, and the weight of thousand seeds was (9.78±0.05)g, sopping water time was about 4h. The seeds germinate regularly with the treatment of GA3, and 200 mg/kg GA3 liquor had the best effect on the germination rate, it's 69.3% in average.
