摘要
以自来水、蔗糖、8-羟基喹啉(8-HQ)和柠檬酸不添加量为保鲜液的基本配方,分别加入不同浓度的羧甲基壳聚糖(CMCS)制成鲜切花保鲜剂,对"西伯利亚"百合切花进行瓶插试验。通过观察测量瓶插百合鲜切花外观品质、丙二醛(MDA)含量、可溶性蛋白质含量和膜透性等形态指标和生理指标,以期明确壳聚糖对百合鲜切花的保鲜效应。结果表明:添加了不同浓度CMCS的各处理都能明显延长百合鲜切花的瓶插寿命,尤其以添加0.10g/L CMCS的处理3保鲜效果最好,能明显延迟花朵开放、保持切花水分平衡、抑制呼吸高峰、平衡细胞膜相对透性,使百合鲜切花瓶插寿命长达15d,比基本配方瓶插寿命延长7d,比自来水对照延长8d。
Using preservative solutions made up of running water,sucrose,8-HQ and citric acid as basic formula,different concentrations of carboxymethyl chitosan(CMCS) were added to preserve cut flower of 'Siberia' lily.In order to investigate the preservation effects of CMCS,a series of physiology indexes and mophologic indexes of cut flower such as the outward appearance quality,MDA content,protein content and membrane penetrability were studied.The results showed that preservatives with different concentrations of CMCS could extend the vase-life of 'Siberia' lily,especially the No.3 treatment with 0.10 g/L CMCS could delay anthesis and maintain water balance,and delay the climacteric,and keep relative membrane permeability balance,and prolong the vase-life to 15 days,which extended 7 days than basic formula which used in this study,and 8 days longer than CK which used running water.
