摘要
以8-羟基喹啉柠檬酸盐和蔗糖为基础液,添加不同浓度对苯二酚组成保鲜剂,对香石竹切花品种"马斯特"进行瓶插处理。实验测定了切花的鲜重、寿命、花径等指标,同时对切花茎基部导管进行了光镜和电镜观察。结果表明,对苯二酚能延缓香石竹切花茎基部堵塞,延迟水分失衡,增大花径,保持切花鲜艳,延迟切花寿命;香石竹切花茎基部导管在瓶插期间形成堵塞,堵塞物质多为不定型物质如粘液或树胶,少量为定型杆菌;堵塞物质并不是影响香石竹切花寿命的唯一因素;150 mg/L 8-HQC+2%蔗糖+1 mmlo对苯二酚的保鲜剂是香石竹切花保鲜的最优配方。
By taking 8-hydroxyquinoline citrate, sucrose as the basic liquid and adding hydroquinone of different concentrations to constitute the antistaling agent, the vase planting test has been conducted. The fresh weight, lift-time and diameter of flower of D. caryophyllus ‘aster＇ were measured, the caudex vessels of the cut flowers were observed with light and scan electron microscopy. The results show that hydroquinone could limit blockage of stem caudex vessels, delay unbalance of water, increase flower diameter, and extend vase life-time ofD. caryophyllus; Stem caudex vessel blockage of vase planting D. caryophyllus formed during vase life, and the blockages often were gums or mucilage, and a few of that were rod-shaped bacteria; the xylem vessel blockages is not the only cause to terminate vase life-time of cut flower D. caryophyllus. The most optimum formula of the antistaling agent for D. caryophyllus cut flower is 150 mg/L 8-HQC ＋2% sucrose＋1mmol hydroquinone.
