摘要
为了提高连翘播种出苗率,发展连翘产业.通过不同处理方法播种对连翘种子出苗率影响的试验研究分析.结果表明,春播以惊蛰后播出苗率高,秋播以9 月下旬播出苗率高;连翘果实9～10 月成熟,以10 月中旬充分成熟的种子播后出苗率高;晒干和阴干的种子以阴干种子播后出苗率高;成熟合格的种子播后以砂壤土出苗率高;在播前冬季种子沙藏处理后播出苗率高;种子用萘乙酸(NAA)200 μg/g溶液催芽处理后播出苗率高.对连翘种子出苗率的试验研究为商州区连翘播种育苗提供科学依据.
Abstract
To enhance the seeding rate of Forsythia suspensa seeds and promote the development of the For-sythia suspensa industry,an experiment was conducted to investigate effects of different treatments on the seed e-mergence rate.The results showed that sowing after Jingzhe in spring or late September for autumn sowing led to higher emergence rate;the seed emergence rate was higher when the fully mature seeds were harvested in mid-October;the seed emergence rate was higher when the air-dried seeds were used compared to sun-dried seeds;the seed emergence rate was higher when using sandy loam for sowing with mature and qualified seeds;the seed emergence rate was higher when using sand storage for winter seed before sowing;and the seed emer-gence rate was higher when using a 200 μg/g solution of naphthaleneacetic acid(NAA)for seed germination treatment before sowing.This experiment provides a scientific foundation for Forsythia suspensa seedling-raising in Shangzhou area.
