Sažetak
Physical and chemical characteristics are a significant factor in assessing the quality and market value of apple fruit. In intensive apple production, new technologies are b eing a pplied t o i mprove t he f ruit q uality. T he a im o f t his work was t o determine influence of the reflective groundcover Lumilys™ on physical and chemical characteristics of apple fruits cv. 'Wilton's ®Red Jonaprince' after harvest and after 18 weeks of storage under normal atmospheric conditions. Reflective groundcover was placed in the plantation between the rows of the examined cultivars, four to six weeks before harvest, and the control was made of non - groundcover rows. The fruits were harvested in the optimal harvesting time and then the color, mass and size of fruits, firmness, starch degradation index, the soluble solids content and total acids were analyzed . By analysis of chromatic values it was found that the products of trees where reflective groundcover was placed within rows had a higher intensity of red color and lower intensity of green color by the CIE L*a*b color system. Reflective groundcover had a positive effect on the significantly higher firmness, the proportion of soluble solids content and the lowest starch degradation index. There was no significant difference in the part of total acids between the treatmants. The fruits that were stored for 18 weeks under normal atmosphere showed a slightly higher loss of fruit weight, lower proportion of soluble solids content and higher firmness. Reflective groundcover Lumilys™ showed a positive effect on physical and chemical characteristics of the fruits of the tested cultivars, which indicates its potential in achieving apple fruits quality standards.
