本文研究了赤霉素与硝酸钾不同浓度浸种对高羊茅四个品种发芽的影响。分析结果表明：高羊茅品种在发芽试验中起主要作用。硝酸钾在0．1％～0．3％浓度范围内，对高羊茅四个品种的发芽起抑制作用。赤霉素对高羊茅四个品种发芽起促进作用，其中以0．2mg／L浓度较为理想。
In this paper, the effects of different concentrations of GA3 and KNO3 on seed germination of four tall fescue cultivars were studied. The results showed that the tall fescue varieties played a major role in germination test. Potassium nitrate in the concentration range of 0.1% to 0.3% inhibited the germination of four varieties of tall fescue. Gibberellin on four tall fescue germination play a catalytic role, of which 0.2mg / L concentration is more ideal.
