Abstract

Abstract: The paper aims to analyze the effects of 3 plant growth retardants (BAS, CCC, PP333) on flowering characteristics of Phalaenopsis, Phalaenopsis variety‘Big chili’was selected as the research material with 5 different concentration treatments. The result showed that: (1) paclobutrazol (PP333) with different concentrations could reduce the height of Phalaenopsis peduncle effectively, up to 7 cm with the concentration of 250 mg/L, BAS and CCC had no significant effect on peduncle height; (2) the three plant growth retardants with different concentrations were slightly positive to the length of inflorescence, PP333 and BAS were positive to the flower quantity, but CCC was not; (3) the three retardants all had slightly positive effect on flower diameter.
