摘　　要：以生长18个月的擎天属观赏凤梨Guzmania‘Calypso’与Guzmania‘Catherine’2个品种为试材,研究了不同催花药剂、浓度及处理次数对观赏凤梨开花的影响。结果表明:饱和乙炔水溶液与不同浓度的乙烯利均能有效促进擎天凤梨开花,但前者见效快,催花效果好,明显优于后者的各浓度梯度。饱和乙炔水溶液处理3～4次是较为理想的凤梨催花处理方式。Taking Guzmania ＇Calypso＇ and G.＇Catherine＇ aged 18 months as experiment materials,the effects of Guzmania on flower forcing with different treatment such as medicament concentration and frequency were studied.The results showed that saturated acetylene solution and ethephon with different concentration could promote flowering effectively,and the former was better than the latter conspicuously.The treatment of saturated acetylene solution with 3~4 times were a fairly ideal method to be used for flower forcing.
