摘要
研究不同浓度的HNO3、KNO3、GA溶液及其不同浓度配比的混合预处理液对薜荔种子发芽的影响。结果表明：不同植株的薜荔种子的各项发芽指标差异显著；适宜浓度的HN03、KN03以及GA溶液对薜荔种子发芽均有促进作用，筛选出的最佳组合（HNO3：37．78mmol／L＋GA：30mg／L）可使薜荔种子的发芽率、发芽势和发芽指数分别为对照组的2．27倍、11．25倍和4．72倍，并使发芽天数缩短到5—6d。
we has studied on the influence of the chemical pretreatments of different concentration of HNO3, KNO3, GA solutions, and their mixed solutions on the frequency of seed germination. The results were showed as follows： there are significant differences on germination percentage, germination energy and germination index of Ficus pumila seeds from different plants. The germination of Ficus pumila seeds were improved by the pretreatment of proper soaking concentration of HNO3, KNO3 and GA solution. The best concentration of the comprehensive treatment was 37.78 mmoL/L of HNO3 and 30 mg/L of GA, compared with the control group, which increased 2.27 times in germination percentage, 11.25 times in germination energy and 4.72 times in germination index,so its germination time shortens 5 -6 days.
