为了解外源激素对高羊茅种子萌发的影响,试验以多年生冷季型草坪草高羊茅(技巧2号、盆景3000)为植物材料,用不同浓度的水杨酸(SA)、赤霉素(GA)和脱落酸(ABA)进行处理,分别研究不同浓度外源激素诱导对高羊茅种子萌发的影响。结果表明:最适合高羊茅萌发的外源激素为0.5 mmol/L SA、300 mg/L GA,可以在一定程度上促进高羊茅种子的萌发;而ABA诱导后对高羊茅的萌发有一定的抑制作用。
In order to understand the effect of exogenous hormones on the seed germination of tall fescue, the perennial cold-season turfgrass fescue (Tiao No. 2 and Bonsai 3000) was used as the plant material, with different concentrations of salicylic acid (SA) (GA) and abscisic acid (ABA). The effects of different concentrations of exogenous hormones on the seed germination of tall fescue were studied. The results showed that 0.5 mmol / L SA and 300 mg / L GA, which are most suitable for germination of tall fescue, could promote the germination of tall fescue seeds to some extent. However, the germination of tall fescue Certain inhibition.
