摘要
利用苦菜[Patrinia villosa(Thunb.)Juss.]种子和插条进行繁殖试验,对繁育成活的幼苗生长情况进行比较分析。结果表明,种子经湿冷处理,去种皮在变温条件下培养皿法播种发芽率最高,为56%;带顶芽插条经过生根粉处理在沙土中扦插成活率和平均生根数最高,分别为83%和9.7根/株;插条繁育幼苗成苗后后期生长快,生长势明显好于种子繁育的幼苗。
Propagation experiment with seeds and cuttings of Patrinia viUosa was conducted to analyze the growth of the sur viving seedlings. Results showed that seeds removed episperm by the wet cold pretreatment had the highest germination rate of 56% under the variable temperature condition. Cuttings with terminal bud had treated by ABT the highest survival rate and average number of root, 83% and 9.7 per plant in sandy soil,respectively. The growth of the seedlings from cuttings was sig nificantly better than that of the seedlings from seeds.
