| 摘 要： | 本文研究了CA3、BA、PP3333种植物生长调节剂对天堂草、马尼拉草两种暖地型草坪草快速成坪的影响。结果表明GA3能促进两种草坪草匍匐茎伸长；BA能促进它们分蘖，并显著促进马尼拉草匍匐茎伸长；而PP333。对两种草坪草的影响则因浓度不同、品种各异而有差异。外施PGR3后可引起草坪草内源激素变化而调节其生长速度及成坪天数。

| Abstract: | The article studied the influence of gibberellic acM(Gas)(25, 50, 150mg/L), benzyladihine(BA)(1.5, 10(mg/L) and pacdobatrazol (PP333) (100, 250, 500mg/L) on quick turf-establishment of Tifway bermudagrass and Manilagrass. The results showed GA3 can accelerate stolon elongation of two kinds of turfgrasses; BA promote their tilledng and obviously stolon elongation of manilagrass; but PP333 treatments have various effects on its concentrations and turfgrass spacies. It could control turfgrass growth speed and tuff-establishment time through externul PGRs application which cause endogenous hormones change. |
