摘要
龙葵种子具有休眠习性,采用合适的化学药剂能够打破龙葵种子休眠。H2O2、NaOH、HCl、KNO3、GA浸泡24 h,均能明显提高龙葵种子的萌发率。以2.25～36.00 g/L HCl浸种的萌发率最高,萌发率超过90.00%;40.00 g/L KNO3与200.00 mg/L GA浸种后,萌发率超过80.00%,已达到打破龙葵种子的休眠的目的。
There is significant dormancy in Solarium n/ffum L. seeds. Treatment with proper chemical agents can be used to break its seed dormancy. Soaking the seeds in H2 02, NaOH, HCI, KNO3 and GA for 24 h increased germination com pared to the untreated control The highest germination rate of over 90% was obtained when the seed was treated with HC1 at 2.25 -36.0 g/L. KNO3 at 40.0 g/L or GA at 200.0 mg/L also increased seed germination to above 80% ,thus these treatments allowed breaking dormancy of S. rdgrum L. seeds.
