| 摘 要： | 以不同干物质类型的甘薯品种绵粉1号、南薯88和商丘52-7为材料,研究了甘薯块根形成与膨大期间碳水化合物积累与淀粉合成相关酶活性的动态变化及其相互关系。结果表明,作为品种的固有特征,干物质含量或淀粉含量的差异主要决定于品种的遗传特性。对于中高干率品种而言,淀粉在生育中后期积累较快。磷酸蔗糖合成酶(SPS)活性与品种间淀粉积累量一致,中等干物质品种(南薯88)中后期的蔗糖合成酶(SS)活性较高,淀粉积累量也最多,SPS和SS对淀粉合成与积累具有促进作用,ADPG焦磷酸化酶有随气温降低而活性下降的趋势。此外不同品种均表现出甘薯块根干物质含量与可溶性糖含量、淀粉产量与可溶性糖含量呈极显著的负相关关系。

| Abstract: | Three sweet potato varieties of different dry matter content were used to research the changes of carbohydrates accumulation and correlated enzymes activities,as well as the relationship among these traits.Results:As an inherent character,the difference of dry matter content or starch content between varieties mainly depend on the variety genetic characteristics.As for the varieties of middle or high dry matter,the starch accumulation is relatively fast at late stages.The activity of SPS is consistent with ... |
