摘  要：
以麝香百合"白天堂"品种切花为试材,对采后茎末端和瓶插液中的主要病原菌进行了分离、纯化和鉴定,并初步探讨了这些病原菌对瓶插寿命的影响。结果表明:该切花采后易于滋生的主要病原菌有假单孢菌属(Pseudomonas sp.)、肠杆菌属(Enterobacter sp.)、鲍氏不动杆菌(Acinetobacter baumannii)和木糖氧化产碱菌(Achromobacter xylosoxidans)4种;用不同浓度的上述病原菌液分别瓶插麝香百合切花,可不同程度地减少花枝的水分吸收、加速花枝的鲜重损失和缩短切花的瓶插寿命。

摘  要：
Taking cut flowers of Lilium longiflorum 'White Heaven' as test material,the species of dominant bacteria were isolated and identified from postharvest cut lilies,and their effects on vase life were investigated.The results showed that two dominant bacteria(Pseudomonas sp.and Enterobacter sp.)were isolated from the stem ends of cut lilies,and another two dominant bacteria(Acinetobacter baumannii and Achromobacter xylosoxidans) were isolated from the vase water in which cut lilies were held.The individiual inclusion of different concentrations of above 4 dominant bacteria in vase water could decrease the water uptake from cut lily stem,accelerate the loss of fresh weight,and shorten the vase life at different levels.
