- Abstract:
- Taking ‘Huangzhonghuang’ cut chrysanthemum as test material,vase life,flower diameter,chlorophyll content and change rate of fresh weight were studied.The results showed that appropriate low concentration of carboxymethyl chitosan could improve preservative effects of cut chrysanthemum. However,carboxymethyl chitosan at high concentration such as 20.0 g·L-1 showed negative effect on the preservation of cut chrysanthemum.Spraying treatment with 1.0 g·L-1 and vase treatment with 0.5 g·L-1extended the life of cut chrysanthemum for 1.0-2.3 days.While,spraying treatment with 4.0 g·L-1 and vase treatment with 0.1 g·L-1 increased the flower diameter of cut chrysantnemum.In addition,the degradation of chlorophyll and the water loss of cut chrysantnemum could be relieved by carboxymethyl chitosan.
