摘要
以P18-2、P98、P129为试材,研究不同耐贮性辣椒在贮藏期间的生理生化变化。结果表明,在10℃下贮藏21 d,随着贮藏时间的延长,不同耐贮性辣椒的生理生化变化趋势相同,果实硬度不断下降,可溶性果胶含量增加,聚半乳糖醛酸酶活性下降,纤维素酶活性上升,可溶性糖含量减少,vC含量降低,含水量下降;但耐贮品种比不耐贮品种的变化趋势平稳。
To provide the theoretic basis about the development of storage and transport technology and breeding of the new long-term storage varieties,physiological and biochemical characteristics were analyzed comparatively concerning the different storability of pepper（Capsicum annuum L.） during storage.Used pepper Cvs.P18-2,P129 and P98 as materials,the fruit were picked in a color-breaking period and fruit stalks were pruned,prior to storage at 10℃ for 21 days.With prolonging storage time,the trends of the physiological and biochemical characteristics were the same in three pepper cultivars.The results showed that fruit firmness and polygalacturonase activity decreased while the soluble pectin content and cellulose activity increased during storage.In addition,contents of vitamin C and soluble sugars,and water content decreased with increasing storage,but long-storage pepper cultivar tended to change more smoothly.
