摘要
用次氯酸钠(NaOCl)、聚乙二醇(PEG)和H_(2)O引发处理金铁锁种子,研究不同处理对金铁锁种子萌发的影响。结果表明:经NaOCl消毒处理的陈年金铁锁种子,置于20℃的恒温条件下,其发芽指数最高,发芽率和发芽势相对也高;水引发处理18 h的金铁锁种子发芽率和发芽势均最高,分别为33.50%和25.10%,处理24 h其发芽指数显著高于其他处理,但其根长、苗长、幼苗鲜重差异不明显;PEG引发处理与其浓度有关,0.5%PEG引发处理比1.0%PEG和2.0%PEG处理更能促进金铁锁种子萌发,用0.5%PEG处理6~18 h能够明显提高陈年金铁锁种子的发芽率、发芽势和发芽指数,从而也可提高其出苗速度,使种苗整齐。
Using sodium hypochlorite(NaOCl),polyethylene glycol(PEG)and H_(2)O to initiate treatment of Psammosilene tunicoides seeds,the effects of different treatments on the germination of P.tunicoides seeds were studied.The results showed that the P.tunicoides seeds treated with NaOCl disinfection,when placed under constant temperature conditions of 20℃,it had the highest germination index,germination rate and germination potential were also relatively high.The highest germination rate and germination potential in the 18 h water initiation treatment,of 33.50%and 25.10%,respectively,the germination index was significantly higher at 24 h than at the other treatments,but its root length,seedling length,seedling fresh weight were not too much difference.The PEG initiation treatment was related to its concentration,0.5%PEG initiation treatment promoted seed germination more than 1.0%PEG and 2.0%PEG treatment,treatment with 0.5%PEG for 6-18 h could significantly improve the germination rate,germination potential and germination index of P.tunicoides seeds,thus could also improve the germination rate of seeds,make the seedlings neat.
