月季切花采后瓶插时的微生物发生以细菌、霉菌为主，放线菌未检出。细菌繁殖速度最快，瓶插前三天细菌检出量呈对数增长，霉菌数量虽少但体形较大，均易造成切花茎切口处的导管堵塞。切花在无菌水和自来水中微生物发生相近。杀菌剂８－羟基喹啉（８－ＨＱ）有抑菌作用，浓度为１００ｍｇ／Ｌ杀菌效果显著。杀菌剂处理还能明显增强花枝的吸水能力，降低蒸腾作用，延长瓶插寿命，同时使叶片过氧化氢酶和ＳＯＤ酶活性分别提高１５．６％和６３．４％。
After the rose cut flowers bottle plug microorganisms occur to bacteria, mold-based, actinomycete was not detected. Bacteria multiply fastest, three days before the bottle amps detected in a logarithmic growth, although the number of molds, but a large body, are easy to cause cuttings at the incision catheter stump. Cut flowers in sterile water and tap water microbial occurrence similar. The bactericide 8-hydroxyquinoline (8-HQ) has bacteriostatic effect, and the bactericidal effect is remarkable at the concentration of 100mg / L. Bactericidal treatment can also significantly enhance the water-absorbing ability of squid, reduce transpiration and prolong the vase life, meanwhile, increase leaf catalase and SOD enzyme activity by 15.6% and 63.4% respectively.
