以华南系列的SC205、SC5、SC6、SC8和SCIO五个木薯品种为材料，于采收后不同时间分析其块根生理变质程度、干物质含量、淀粉含量、支链淀粉比例和淀粉透明度等指标，探讨木薯生理变质与块根淀粉特性的关系。研究结果表明：采后生理变质对块根淀粉特性有明显影响，所有品种淀粉特性指标在采后均呈下降趋势，其中下降最快的是SC205。对各指标的相关分析表明，支链淀粉分别与淀粉含量和淀粉透明度呈显著正相关和极显著正相关。可见，生理变质可导致淀粉透明度的下降，影响淀粉的商品品质。

The rapid physiological deterioration (PD) of cassava tuberous root is main constraint factor that limits the development of cassava industry. In order to know the relationship between PD and starch characteristics on cassava, there are five varieties subjected ( SC205, SC5, SC6, SC8 and SC10) on four indices, including dry matter, starch content, amylopectin content and starch clarity. The result showed that the indices of starch characteristics were decreased by PD in all subjects, and the decline of SC205 was appeared earlier than others. The correlation analysis were indicated that Positive correlation and significant positive correlation between amylopectin content and starch content, amylopectin content respectively. Thus, we can see starch clarity was affected by the PD during storage, and starch quality of cassava tuberous root was also cut down greatly.
