红地球葡萄贮藏效果预测因子初探

研究目的】研究不同产地红地球葡萄品质指标及发病率的变化，明确影响红地球葡萄贮藏效果的主要因素。【研究方法】以5个不同产地红地球葡萄为试验材料，测定冷藏条件下果实的带菌率、果梗含水量、发病率、可溶性固形物、可滴定酸及多酚含量的变化。【研究结果】不同产地红地球葡萄的贮藏特性不同，其中怀来葡萄的带菌率与发病率均较低，果梗含水量低且下降缓慢（下降率为5.60%），可溶性固形物含量和多酚含量高，比其他产地葡萄有更好的抗病性。各指标与果粒发病率相关程度不同，贮藏过程中可溶性固形物含量及果肉多酚含量变化与发病率的相关系数均大于0.828；采收时红地球葡萄果肉多酚含量与贮藏80d后果粒发病率相关系数为0.885。【结论】贮藏过程中可溶性固形物含量及果肉多酚含量变化可以较好的监测葡萄发病率的变化，采收时红地球葡萄果肉多酚含量能够作为大批量红地球葡萄贮藏效果的预测因子
