Abstract: Different preservative formulas, preconditioning liquids and refrigerating time influenced on vase life and quality of cut Strelitzia reginae flowers were studied.The results showed that 5% S+300 mg/L 8-HQC+100 mg/L CA+150 mg/L STS+100 mg/L CoCl₂+25 mg/L EDTA-Na was the best of the 8 various preservatives.The vase life of cut flower (23.5 days) lengthened 15.2 days, and the blooming rate of small flowers (56.1%) increased by 1.19 times compared to CK.The prescription of 10% S+300 mg/L 8-HQC+75 mg/L KH₂PO₄·3H₂O was the best of the 5 various preconditioning liquids.The vase life of the cut flower was 13.7 days after refrigeration of 2 to 3 weeks under 8~10℃.The vase life lengthened 7.9 days, and the blooming rate of the small flowers (43.6%) increased by 98.2%.The suitable cold storage time for cut Strelitzia reginae flowers could lengthen to 3 weeks.

摘要： 本文探讨不同保鲜剂、预处理液及冷藏时间对鹤望兰切花瓶插寿命和观赏品质的影响。结果表明,供试的8组瓶插保鲜液中,以配方5% S+300 mg/L 8-HQC+100 mg/L CA+150 mg/L STS+100 mg/L CoCl₂+25 mg/L EDTA-Na保鲜效果最佳,切花瓶插寿命(23.5 d)比CK延长15.2 d,小花开放率(56.1%)比CK提高1.19倍。供试的5组冷藏预处理液中,以10% S+300 mg/L 8-HQC+75 mg/L KH₂PO₄·3H₂O效果最佳,切花经过2~3周8~10℃冷藏后,瓶插寿命(13.7 d)比CK延长7.9 d,小花开放率(43.6%)比CK提高98.2%;该处理组鹤望兰切花的适宜冷藏时间可延长为3周。
