原料蔗品质变劣程度与品种本身及贮存时间的长短有着密切的关系．随着贮存期间的延长，蔗茎蔗糖分等７个品质指标呈不同程度的下降趋势，蔗汁还原糖分等６个生理指标有着不同程度的上升．经方差分析和多重比较，综合评价这些生理指标，认为福引８３－１３原料蔗品质变劣程度最大，其次为闽糖７０－６１１和桂糖１１号．在贮存前期，与原料蔗糖分变化相关的酸／中性转化酶活性也随之提高，尤以酸性转化酶活性提高最为显著；到后期，活性提高渐缓并略有下降，其中中性转化酶活性下降程度高于酸性转化酶．收获后甘蔗的糖分损失主要通过转化和呼吸作用进行
The quality deterioration of raw cane is closely related to the variety itself and the storage time. With the prolongation of storage period, the seven quality indexes of cane sucrose fraction declined in different degrees, and the six physiological indexes of cane juice reducing sugar fraction increased in varying degrees. Through variance analysis and multiple comparisons, these physiological indexes were comprehensively evaluated, which indicated that the quality of Fuyin 83-13 raw material was the worst, followed by Fujian 70-611 and Guitang 11. In the early stage of storage, the activity of acid / neutral invertase related to the change of sucrose content of raw materials also increased, especially the activity of acid invertase increased most significantly. At the later stage, the activity increased slowly and slightly, and the neutral invertase Activity decreased more than acid invertase. After sugar cane sugar loss is mainly through the transformation and respiration
