甜高粱露天贮藏SS、SPS酶活性与蔗糖代谢的研究
Studies on the Activities of SS and SPS Enzymes and Sucrose Metabolism of Sweet Sorghum under Open-air Storage
摘要
Abstract
[Objective] The purpose of the project was to make clear the crucial enzyme of sucrose degradation in order to resolve the problem that sucrose is easy to biodegrade by the means of molecular regulation of key enzymes during storage of sweet sorghum culms.[Method] The new sorghum NO.9 (T601)was used as the test material,sucrose content of well-shaped stored sorghum without ears and leaves and of those with leaves but no ears in stacked storage and the variation and correlation of SS and SPS enzymatic activities were studied.[Result] The correlation between the SS and SPS activities and the sucrose content during the storage was not significant and the content would drop sharply to the lowest point when the sorghum culm was stored for five months.[Conclusion] Well-shaped stored sorghum with leaves but no ears is more favorable for keeping sucrose content of culms than those without ears and leaves,but mildewed and rotten ones become the restricting factors for the storage of sorghum culms with leaves but not ears.The height of the storage stack should be no higher than two meters.关键词
