摘 要 ：芋种质资源品质性状分析结果表明：按球茎类型来分，干物质含量：魁芋＞多头芋＞魁子兼用芋＞多子芋。淀粉含量：魁芋＞魁子兼用芋＞多头芋＞多子芋，干物质和淀粉含量都以魁芋最高，分别为27.38%、20.21%，多子芋最低，分别为19.54%、13.35%。蛋白质含量：多头芋＞魁芋＞多子芋＞魁子兼用芋，以多头芋的含量最高，为1.54%，其它类型相差不大。可溶性糖含量：魁芋＞魁子兼用芋＞多子芋＞多头芋，以魁芋的可溶性糖含量最高，为1.21%，其它芋类型相差不大。按母芋芽色来分，多子芋中，干物质、淀粉和蛋白质含量：红芽多子芋＞白芽多子芋，可溶性糖含量：白芽多子芋＞红芽多子芋；多头芋中，干物质、淀粉、可溶性糖：白芽多头芋＞红芽多头芋，蛋白质含量：红芽多头芋＞白芽多头芋。在整个芋种质资源中，芋的干物质含量与淀粉含量（r=0.9583**）、干物质含量与蛋白质含量（r=0.5529**）、淀粉含量与蛋白质含量（r=0.5284**）呈极显著正相关，干物质含量与可溶性糖含量（r=-0.2934**）、淀粉含量与可溶性糖含量（r=-0.3391**）、蛋白质含量与可溶性糖含量（r=-0.4498**）都呈极显著负相关。本文还按叶柄颜色类型对芋种质资源品质性状进行了测试分析。

Abstract:Abstract: Analysis on quality characters of taro germplasm resource was done. It indicated that: divided by corm type, the turn of dry matter content was: taro with large corm＞taro with multi-headed corm＞taro used for both corm and cormels＞taro with numerous cormels. The turn of starch content was: taro with large corm＞taro used for both corm and cormels＞taro with multi-headed corm＞taro with numerous cormels. Dry matter content and starch of taro with large corm were the highest, which were 27.38% and 20.21% respectively. Dry matter content and starch of taro with numerous cormels were the lowerest, which were 19.54% and 13.35% respectively. The turn of protein content was: taro with multi-headed corm＞taro with large corm＞taro with numerous cormels＞taro used for both corm and cormels. Protein content of taro with multi-headed corm was the highest, which was 1.54%. There was no obvious difference among those of the others. The turn of soluble sugar content was: taro with large corm＞taro used for both corm and cormels＞taro with numerous cormels＞taro with multi-headed corm. Soluble sugar of taro with large corm was the highest, which was 1.21%. There was no obvious difference among those of the others. Divided by the color of corm bud, in taro with numerous cormels, the turn of dry matter content, starch content and protein content was: Taro (red bud) with numerous cormels＞taro (white bud) with numerous cormels. The turn of soluble sugar was: Taro (white bud) with numerous cormels＞taro (red bud) with numerous cormels. In taro with multi-headed corm, the turn of dry matter content, starch content and soluble sugar content was: Taro (white bud) with multi-headed corm＞Taro (red bud) with multi-headed corm. The turn of protein content was: Taro (red bud) with multi-headed corm＞Taro (white bud) with multi-headed corm. In all taro germplasm resources, there was very distinct correlation between dry matter content and starch content (r=0.9583**), dry matter content and protein content (r=0.5529**), starch content and protein content (r=0.5284**). There was very negative distinct correlation between dry matter content and soluble sugar content (r=-0.2934**), starch content and soluble sugar content (r=-0.3391**), protein content and soluble sugar content (r=-0.4498**). In this article, analysis on quality characters of taro germplasm resource was also done, divided by petiole color.
