| 摘 要： | 通过对牡丹切花瓶插寿命、水分平衡值、花瓣可溶性蛋白含量、花瓣细胞膜透性的测定,研究了不同浓度的壳聚糖涂膜保鲜液对壳聚糖切花的保鲜效果。结果表明:壳聚糖涂膜液可明显抑制牡丹切花水分的蒸腾,减缓花瓣中可溶性蛋白的降解和细胞质膜的损伤,延长瓶插寿命。其中,以4g/L的壳聚糖处理对牡丹切花的保鲜效果最佳。

| Abstract: | The effect of chitosan coating on fresh-cut tree peony preservation,including vase life,water balance value, soluble protein content in petals,the relative electric conductivity of petals was examined.The results showed that application of chitosan coating delayed the transpiration,slowed down the progress of soluble protein degradation and membrane damage,prolonged the vase life of cut tree peony,the best retain freshness for cut tree peony was 4 g/L chitosan solution. |
