摘    要:[目的]测定菠萝蜜不同种质成熟果实的可溶性总糖和淀粉含量,了解现有种质群体果实中可溶性总糖含量与淀粉含量之间的关系。[方法]以39份菠萝蜜种质为材料,其中4份分别在2次不同的时间取样1次,采用蒽酮比色法测定菠萝蜜果实中可溶性总糖含量和淀粉含量。[结果]当可溶性总糖含量在16.00%~20.00%时,淀粉含量在0.36%~4.46%;当可溶性总糖含量在20.01%~25.00%时,淀粉含量在0.42%~3.61%;当可溶性总糖含量在25.01%~30.00%时,淀粉含量在0.28%~3.10%;当可溶性总糖含量在30.01%~35.05%时,淀粉含量在2.08%~2.78%。在不同时间取样的4份种质中,后取样种质的可溶性总糖和淀粉含量相比先取样种质稍有下降。[结论]菠萝蜜果实中可溶性总糖和淀粉在一定含量范围内呈正相关关系。

关 键 词:菠萝蜜  可溶性总糖  淀粉

Abstract:Objective] The aim was to determine total sugar and starch content in different germplasm determination of jackfruit ripe fruit to un-derstand the relationship between the existing germplasm and fruit sugar content and starch content .[ Method] With 39 copies of jackfruit germ-plasm materials of which four were sampled at two different sampling time ,we determined the content of total soluble sugar and starch content in the fruit of jackfruit by anthrone colorimetry.[ Result] When the total soluble sugar content was 16.00% -20.00%,the starch content was 0.36%-4.46%;when the total soluble sugar content was 20.01%-25.00%,the starch content was 0.42%-3.61%;when the total soluble sugar content was 25.01%-30.00%,the starch content was 0.28%-3.10%;when the total soluble sugar content was 30.01%-35.05%,the starch content was 2.08%-2.78%.Among them,the total soluble sugar and starch contents of the four kinds of samples which were sampled at different time were decreased compared with the first sample.[Conclusion] The soluble total sugar and starch content of jackfruit fruit showed a positive correlation in a certain range.
Keywords:Jackfruit  Soluble total sugar  Starch
