【目的】为明确甜高粱茎秆贮存过程中蔗糖降解的关键酶,以期通过对蔗糖降解关键酶的分子调控解决甜高粱茎秆贮存过程中蔗糖易降解的难题。【方法】以新高粱9号(T601)为试验材料,研究了井型去叶去穗、井型带叶去穗堆放贮藏方式下茎秆蔗糖含量与SS、SPS酶活性的变化规律及相关性。【结果】在贮藏期间SPS、SS与蔗糖含量相关性都不显著,蔗糖含量当贮藏达到5个月时,急速下降至最低。【结论】带叶去穗井型贮藏较去叶去穗井型贮藏更有利于甜高粱秸秆蔗糖含量的保存,但是霉变腐烂成为带叶去穗型贮藏的限制性因素,贮藏堆放高度应控制在2 m以下。
【Objective】 To clarify the key enzyme of sucrose degradation during the storage of sweet sorghum stalks, in order to solve the problem of sucrose degradation during the storage of sweet sorghum stalks through the molecular regulation of key enzymes of sucrose degradation. 【Method】 New sorghum 9 (T601) was used as experimental material to study the changes of sucrose content, SS, SPS enzyme activity and the correlation between the stem sucrose content, . 【Result】 There was no significant correlation between SPS, SS and sucrose content during storage. The content of sucrose rapidly decreased to the lowest when storage reached 5 months. 【Conclusion】 It is more beneficial to preserve the sucrose content of sweet sorghum stalks than that of de-ear spike wells, but the mildew decay is the limiting factor for the storage of leaf-spike panicles. The storage height should be controlled Below 2 m.
