6种植物生长调节剂对菵草种子萌发的影响

Effect of Six Plant Growth Regulators on Germination of Seeds of Beckmannia Syzigachne

采用不同浓度的苄氨基嘌呤、吲丁·萘乙酸、复硝酚钠、芸苔素内酯、S-诱抗素、赤霉酸处理菵草(Beckmannia syzigachne)种子,通过测定菵草种子发芽率、发芽势、发芽指数和活力指数等指标,研究了6种植物生长调节剂对菵草种子萌发的效应。研究发现,750mg/L的吲丁·萘乙酸及100、200、400、1600mg/L的芸苔素内酯处理对菵草种子的萌发均有明显的促进作用,而75、150、300、600mg/L的S-诱抗素处理均显著抑制菵草种子的萌发。

Different concentrations of benzylaminopurine,indole naphthalene acetic acid,sodium nitrophenol,brassinolide,S-elicitor and gibberellic acid are used to treat beckmannia syzigachne seeds.The effects of different concentrations of plant growth regulators on seed germination rate,germination potential,germination index and vigor index of Beckmannia syzigachne are studied by measuring germination rate,germination potential,germination index and vigor index of Beckmannia syzigachne seeds.The results show that the germination rate of Beckmannia syzigachne is obviously promoted by the treatment of benzylaminopurine 1600mg/L,indole naphthalene acetic acid 750mg/L and brassinolide 100,200,400,1600mg/L.S-elicitor can significantly inhibit the germination of Beckmannia syzigachne seeds at concentrations of 75,150,300 and 600mg/L.
