| 摘 要： | 以 '富士'、'国光'、'红星'、'金冠'和'嘎拉'5个苹果品种为试材,分析了果实发育成熟过程细胞壁物质(CWM)、水溶性果胶(WSP)、共价结合果胶(CSP)、离子结合果胶(ISP)、纤维素及半纤维素各组分变化.结果表明:在苹果果实发育过程中,5个品种果实CWM含量变化均呈先升后降的变化规律,均以果实膨大期为其含量下降的转折点;果实总果胶含量均呈不断降低的趋势,其中CSP为主导成分,'富士'和'国光'果实CSP含量最高,WSP含量最低,'嘎拉'与'红星'果实3种果胶含量变化居中,'金冠'果实总果胶含量最低且变化小,但在近成熟期'红星'和'金冠'果实WSP呈明显的上升趋势.果实半纤维素含量也具相似的变化规律,'国光'、'富士'和'金冠'等3个品种的高峰值显著高于'嘎拉'和'红星';比较5个品种纤维素含量,'国光'果实在成熟期之前显著高于其他4品种,而其他4品种的纤维素含量变化比较平稳.

| Abstract: | Five apple cultivars,'Fuji','Ralls','Starking delicious','Golden delicious' and 'Gala',were used as materials to analyze the changes of cell wall material(CWM),water soluble pectin(WSP),covalently bound pectin(CSP),ionic bound pectin(ISP),hemi-cellulose and cellulose during fruit development and maturation.The results showed that cell wall material content of the five apple cultivars were increased at first and then decreased,and their decline turning point were at fruit expanding process.The content of tot... |
