摘      要：[Objective] This study aimed to establish the technical system for forcing ornamental pineapple in Guzmania to flower and further provide technical parameters for large-scale cultivation.[Method] The effect of different concentrations of ethephon solution on flowering in Guzmania ornamental pineapple was studied by using randomized block design.[Results] All the different concentrations of ethephon solution were capable to force the four mainly-cultivated ornamental pineapple varieties to flower to varying *** the flower forcing,it took about 180 d for the pineapple to stay in the ornamentation period,and there were no significant differences in inflorescence shape,inflorescence height,inflorescence diameter and bract number among different treatment pineapples.[Conclusion] All the four varieties have shown high sensitivity to *** optimal ethephon concentration is 400 mg/L for treating ***,*** and *** and 500 mg/L for treating *** treatment,their major ornamentation traits are were able to satisfy the requirements for commercial production of pineapple.
