摘要(Abstract)：

【目的】为了探讨绿色木霉菌发酵液处理对杧果采后病害生理的影响,【方法】以紫花杧果为试验材料,利用绿色木霉菌(T.viride)发酵液对杧果进行处理,测定杧果采后生理指标的变化。【结果】结果表明,在(30±2)℃、RH90%~95%条件下,T.viride发酵液处理可降低采后杧果的呼吸强度,并使其呼吸高峰推迟1 d。处理组果实可溶性固形物的最大值出现在第8天,比对照组推迟了2 d;其健康组织维生素C第3天上升至最高含量,分别达164 mg.kg-1和173 mg.kg-1,而对照组和处理组的病斑周围组织的维生素C含量在0~9 d内均呈现下降趋势。T.viride发酵液处理延缓了病斑周围组织的可滴定酸下降,损伤接种至第6天,处理组果实病斑周围的可滴定酸为0.36 mg.g-1,高出对照组16%。处理组病斑周围的蛋白质含量最高峰出现在第6天,比对照组延迟1 d。T.viride发酵液处理降低了杧果组织丙二醛含量,处理组和对照组的最大值分别为4.18μmol.L-1、5.23μmol.L-1;贮藏1~9 d,处理组和对照组的总酚含量差异不显著。【结论】绿色木霉菌发酵液处理能有效减缓杧果采后病害生理活动。
