摘要
播娘蒿种子休眠的自动破除约需半年时间．研究了不同药剂对破除其休眠的效应．结果表明：药剂浸种可迅速打破其种子休眠，其中以３０％浸种３０ｍｉｎ作用最显著，破眠率可达９３％；其次是３００×１０－６ＧＡ３浸种２４ｈ；ＮａＯＨ，丙酮，ＰＥＧ，ＰＶＡ等作用较弱．
It takes about half a year for D.sophia seeds to break their dormancies.Researches on the effect of various chemicals on breaking dormancies of D.sophia seeds indicate that D.sophia can quickly break their dormancies after being soaked in chemicals;the effect of soaking in 30 % H O for 30 minutes is the most significant and the dormancy breaking rate can reach as high as 93 %;the effect of 300×10 -6 GA 3 folows it;NaOH,aceton,PEG,PVA exert a little effect.
