在这项研究中，生物散斑技术进行了评估，用于监测苹果牛眼腐烂的发展和产品质量一般，在各种条件下储存和随后的货架期。这种非破坏性的光学方法是基于对从样品散射的激光变化的分析。对牛眼腐病敏感的品种Pinova和Topaz的苹果用于两个独立的实验。首先，苹果在冷藏期间被非破坏性地监测了五个月。在此之后，34%的Pinova'和21%的'黄玉'苹果显示出可见的表面病变。在真菌病害的发展过程中，观察到生物斑点活性的增加。在第二个实验中，使用了各种储存条件，并通过非破坏性和破坏性方法在其货架期内对苹果进行了测试。该研究表明，无论储存条件如何，生物斑点活性在保质期内都会降低。
In this study, the biospeckle technique was evaluated for monitoring of apple bull's eye rot development and product quality in general, during storage under various conditions and during subsequent shelf life. This non-destructive optical method is based on the analysis of laser light variations scattered from the sample. Apples of the cultivars Pinova' and 'Topaz', susceptible to bull's eye rot, were used in two independent experiments. In the first, apples were non-destructively monitored for five months during cold storage. After that time, 34% of Pinova' and 21% of 'Topaz' apples displayed visible surface lesions. The increase of biospeckle activity was observed during the development of fungal disease. In the second experiment various storage conditions were used and apples were tested during their shelf life by non-destructive and destructive methods. This study showed that biospeckle activity decreased during shelf life, irrespective of storage conditions.
