摘要
对不同发育时期牡丹切花采后的瓶插生理特性以及保鲜液的调控效应进行了研究。结果表明:蒸馏水(对照)瓶插牡丹切花,从露色期到盛开期随着开放级别的升高瓶插寿命和最佳观赏期相应缩短,保鲜液能够延长瓶插寿命和最佳观赏期,提高最大花径和花枝鲜样质量;牡丹切花瓶插期间花枝吸水量和失水量持续下降,水分平衡值在瓶插1d达到最大,保鲜液能够改善花枝的水分状况,延迟水分平衡值趋于0的时间,瓶插期水分平衡值降为零的时间与瓶插寿命呈显著的正相关。牡丹切花的适宜采收期为绽口期到初开期,保鲜液能够改善切花的观赏品质。
Vasing physicological characteristics of cut peony flowers in various development stages and the regulating effect of fresh-keeping solution on the quality and vase life of cut flower were studied.The results showed that the vase life and the optimum ornamental period of cut peony flowers are relatively short under distilled water（control） with the flower stage increasing from bud occuring color stage to full-blooming stage,whereas were prolonged under the floral preservative which could raise the max flower diameter and the fresh weight of flowering branches.In vase period,the water absorption and loss of flowering branches decreased continuously,and the water balance value reached the maximum at 1 day of inserting in distilled water condition.However,fresh-keeping solution could improve water status,and delay the time of hydrologic balance value going down to zero,which showed significantly positive correlation with vase life.It is therefore proposed that the optimum harvesting period of cut peony flowers is from soft bud stage to begin opening stage,and the floral preservative could improve the quality of cut peony flowers in vase-holding.
