| 摘 要： | 以3a生灵武长枣树的枣果、当年生茎和叶为试材,采用分光光度法,研究不同发育时期灵武长枣果实中多糖的含量变化规律及其多糖动态积累的相关性.结果表明:不同发育时期叶片中的多糖含量达到极显著差异,在果实的坐果期达到最高值,膨果期末降至最低值,从着色期开始多糖含量有所增加；茎中多糖含量变化差异不显著；果实中多糖含量在坐果期、膨果期和着色期变化平稳,成熟期急剧升高至积累高峰,含量为12.33％；随着果实发育成熟,外果皮和中果皮中的多糖含量逐渐升高,并存在极显著差异,而内果皮中多糖含量呈先上升后下降的趋势.表明,灵武长枣果实多糖主要在果实的膨果期积累,成熟期时多糖含量最高,中果皮为多糖积累的主要部位,果实中多糖的积累与茎和叶存在一定的相关性.

| Abstract: | Using spectrophotometer,3 years old Jujuba fruits,annual stems and leaves as materials,the Zizyphus jujuba Mill cv.lingwuchangzao fruit polysaccharide accumulation in different period of fruit growth were studied.The results showed that the polysaccharide content of the leaves at different developmental stages showed significant differences,but the content of the stem was not significant differences.The content of 'Lingwu changzao' polysaccharide was at lower in the earlier stage,and with the development of... |
