【摘要】 本文研究了GA3、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PGRs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更多还原

【Abstract】 The article studied the influence of gibberellic acid(GA3)(25,50,150mg/L),benzyladinine(BA)(1,5,10(mg/L) and pacdobutrazol (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 tillering 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 turf-establishment time through external PGRs application which cause endogenous hormones change.更多还原
