| 摘 要： | 采用不同浓度的赤霉素(GA3)、硝酸钾(KNO3)和氯化汞(HgCl2)溶液等几种化学试剂浸泡种子的方法,对秦岭冷杉种子的萌发特性进行研究,旨在寻求适宜的化学试剂,并确定最佳使用浓度,以提高秦岭冷杉种子发芽率。结果表明,不同质量浓度的赤霉素溶液均可显著提高种子的发芽率,其中200 mg/L的赤霉素处理的种子发芽率最高,较对照(清水浸泡)提高110%;不同浓度的硝酸钾溶液对秦岭冷杉种子发芽的影响不明显;不同浓度氯化汞溶液对秦岭冷杉种子的发芽有抑制作用。

| Abstract: | Qinling Fir(Abies chensiensis) is an evergreen tree belonging to Pinaceae abies,and it is an endemic and endangered plant in China and entitled as the second-class state protection plant.Theory and research on mechanism of seed dormancy and germination have been explored systemically in trees,however few articles were reported on seed dormancy and germination of Qinling Fir.This article focused on the germination of Qinling Fir seeds soaked with chemicals,including gibberelin(GA3),potassium nitrate(KNO3) an... |
