Abstract:

[Objective]The effect of spraged with different concentrations of GA,6-BA,NAA and PP333 on the growth and flowering in the Ixora chinensis were studied.The objective of the study is to provide the theoretic basis for the regulation of flowing.[Result]GA and PP333 could delay the flowering date to different degree,but NAA and 6-BA could early the flowering date and improve the ornamental quality of the Ixora. GA could promote the growth of new branches, PP333 has a obvious dwarfing effect to Ixora and NAA can increase the chlorophyll content of Ixora.[conclusion]300 mg/l GA and 400 mg/l 6-BA had better comprehensive effects on improving plant type of Ixora and increasing the quality of the cutting flower.
