摘要
用不同浓度的BTH溶液处理采后枇杷果实,贮藏于常温(22℃)和低温(3℃)下,考察了BTH对枇杷果实贮藏期间病害和品质的影响。结果显示,BTH降低了枇杷果实在常温条件下的自然发病的病情指数,减小了接种炭疽菌枇杷的病斑的直径;BTH提高了枇杷果皮的木质素含量和苯丙氨酸解氨酶活性,表明BTH激活了枇杷的防御系统;与对照相比,BTH处理降低了枇杷的果肉硬度,提高了枇杷的可溶性固形物和可滴定酸含量,无论在常温下还是低温下贮藏均如此。表明BTH对保持枇杷的品质有一定的效果。
Postharvest loquat (Eriobotrya japonica Lindley) fruits were treated with different concentrations of BTH solution and stored at normal temperature (22 ℃) or low temperature (3 ℃) for observing the occurrence of pathogenic diseases and changes in fruit quality. The results showed that BTH reduces the disease index of natural infection of loquats at normal temperature and lesion diameters of loquats inoculated with Colletotrichum acutatum. At the same time, BTH elevates the content of lignin and the activity...
