摘要
革叶铁榄隶属山榄科铁榄属,是一种具有重要生态修复价值和园林绿化潜力的树种。为促进革叶铁榄的育种繁育,以革叶铁榄种子为试验材料,对其种子进行不同条件处理,研究其萌发率、发芽率、发芽值、平均发芽日数。结果表明:随着浓度的升高各指标呈现先上升后下降的趋势。体积分数为0.5%的乙烯利(ETH)、浓度为0.005g·mL^(-1)的赤霉素(GA3)的处理效果最佳,萌发率分别为83.33%和76.00%;且萌发速度最快,发芽最整齐。
Sinosideroxylon wightianum listed as Sinosideroxylon ,Salicaceae.It is a native tree species with important ecological restoration value and potential for landscaping.In order to reveal the germination law of S.wightianum and apply it to breeding,the germination experiments were taken under different treatment conditions.All the seeds were collected from South Mountain Park.The results showed that,the group that treated with 0.5% （volume fraction） ETH had the highest germination rate （83.33%） after treated 24 hours.And it′s germination speed was fastest and it′s germ was most neat and tidy.The group that treated with GA 3 （0.005 g ·mL -1 ） also had the highest germination rate （76.00%） and the fastest speed.Concluding that the two reagents both could facilitate the germination of Sinosideroxylon wightianum significantly.
