摘要
萘乙酸 (NAA)、矮壮素 (CCC)、多效唑 (PP333)、生根粉 (ABT)、脱落酸 (ABA)、吲哚乙酸 (IAA)影响铺植草坪生根数、根长及新建草坪草株高、分蘖和叶片 ,研究结果表明 :矮壮素、多效唑和脱落酸对降低株高、抑制叶片生长有较为明显的作用 ;脱落酸、萘乙酸、矮壮素和多效唑对野牛草、早熟禾和高羊茅分蘖均有显著的促进作用 ;萘乙酸、生根粉、吲哚乙酸和矮壮素对生根有一定的效果。在适宜浓度下 ,上述植物生长调节剂对快速成坪。
The effects of 6 plant growth regulators, including NAA, CCC, ABT, ABA and IAA, on root number, root length, tiller number, height and leaf growth of turfgrass were studied. The results indicated that 1) CCC, ABA and PP333 showed significant influence to reduce height and to restrain leaf growth; 2) ABA, NAA,CCC and PP333 could improve tiller numbers; 3) NAA, ABT ,IAA and CCC had obviously stimulating effect on root. With proper concentration, the regulators could speed up turf establishment, reduce vain growth and cut frequency.
