The application of anti-hail nets is a practice that has been employed for a long time on different fruit and vegetable cultivations and in different fields of the world. In this work, we checked the effects of shading with white anti-hail nets on the post-harvest quality of "Soreli" kiwifruit collected at two different °Brix (7-8 and 8-9) from vineyards of two different ages (8 and 9 years) and stored at 1 °C for 90 days. It was observed that during the storage, the firmness and color parameters (L*, a*, b*, and Chroma) and the SSC content were generally higher in kiwifruit samples harvested in open field than in those under the nets. Regarding the bioactive compounds, the open field samples showed higher values in total flavonoids content during storage, and the content of carotenoids and chlorophylls in fruits grown in open fields was higher from 30-45 days up to the end of the storage. In contrast, the polyphenols and ascorbic acid values of fruits in open fields and under the nets showed a similar evolution of the values from 45 to 60 days. In general, the early and late harvest time based on the °Brix values and the different ages of the kiwifruit plants under the nets did not affect the quality parameters.
防雹网的应用是一项在世界不同地区的各种水果和蔬菜种植中已使用很长时间的做法。在这项研究中，我们检测了白色防雹网遮光对从两个不同树龄（8年和9年）的葡萄园采收的、两种不同糖度（7 - 8和8 - 9）的“索雷利”猕猴桃采后品质的影响，并在1℃下贮藏90天。观察到在贮藏期间，露天采收的猕猴桃样品的硬度、颜色参数（L*、a*、b*和色度）以及可溶性固形物含量通常高于网下采收的样品。关于生物活性化合物，露天样品在贮藏期间总黄酮含量较高，露天种植的果实中类胡萝卜素和叶绿素含量在贮藏30 - 45天直至贮藏结束时较高。相比之下，露天和网下果实的多酚和抗坏血酸值在45至60天内呈现相似的变化趋势。总体而言，基于糖度值的早采和晚采时间以及网下猕猴桃植株的不同树龄并未影响品质参数。
