以清见杂柑为研究材料,进行定点和定期的跟踪测定,探究清见果实囊衣中果胶类物质、纤维素、半纤维素、木质素含量和果胶甲酯酶、多聚半乳糖醛酸酶、纤维素酶活性在花后120~300 d的动态变化情况,及其与清见果实囊衣绵韧程度的相关性。结果表明:囊衣胞壁物质含量在成熟后期均有下降,多聚半乳糖醛酸酶和纤维素酶活性在后期处于上升趋势,果胶甲酯酶则相反;较高水平的水溶性果胶和低水平的木质素、纤维素、半纤维素有利于清见果实良好化渣性的形成;从花后210~300 d,细胞壁中多聚半乳糖醛酸酶、纤维素酶活性高低是决定囊衣质地绵韧程度的关键因子。
In order to find out the hybrid citrus as the research material, we carried out the fixed-point and regular follow-up determination to explore the pectin, cellulose, hemicellulose, lignin and pectin methylesterase, polygalactose The dynamic changes of aldalase and cellulase activities after 120-300 d after anthesis were studied. The results showed that the contents of cell wall material in the capsicum decreased at the late mature stage, the activities of polygalacturonase and cellulase increased at the later stage, and the pectin methylesterase was opposite. The higher levels of water-soluble pectin And low levels of lignin, cellulose and hemicellulose were beneficial to the formation of better slag quality. From 210 to 300 d after anthesis, the activity of polygalacturonase and cellulase in the cell wall was determined The key factor in the softness of the garment texture.
