【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。更多还原

【Abstract】 There is significant dormancy in Solanum nigrum L.seeds.Treatment with proper chemical agents can be used to break its seed dormancy.Soaking the seeds in H2O2,NaOH,HCl,KNO3 and GA for 24 h increased germination compared to the untreated control.The highest germination rate of over 90% was obtained when the seed was treated with HCl 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.nigrum L.seeds.更多还原
