摘要
用高锰酸钾、硼酸、奈乙酸和吲哚乙酸对珍珠绣线菊种子进行浸种处理,研究不同化学药剂和植物激素对其种子发芽的影响。结果表明:高锰酸钾、硼酸、奈乙酸和吲哚乙酸对珍珠绣线菊种子发芽具有明显的促进作用,它们的最适质量浓度分别为2.0mg.L-1、0.2mg.L-1、20.0mg.L-1和10.0mg.L-1,硼酸和吲哚乙酸的处理效果好于高锰酸钾和奈乙酸。
Treating seed of Spiraea blumei with KMnO4 and H3BO3 and IAA and NAA,effects of chemicals and plant growth regulators was studied.Results of seed germination showed KMnO4 and H3BO3 and IAA and NAA could significantly increase the seed germinating ability. The optimum mass concentrations of them are 2.0 mg·L-1, 0.2 mg·L-1 and 20.0 mg·L-1 and 10.0 mg·L-1, separately. The treating effect is H3BO3 and IAA better than KMnO4 and IAA.
