Abstract

T HE effects of preharvest foliar application of salicylic acid, calcium acetate and proline alone or in combinations on fruit quality and storability of “Early Sweet” peaches cultivar were investigated during 2020 and 2021 seasons. The results showed that preharvest application of all treatments increased fruit flesh firmness as compared with control treatment. Salicylic acid treatment increased fruit weight, size and diameter. Moreover, decreased total sugars and fruit weight loss after storage. The results also showed that, calcium acetate treatment enhanced physical and chemical properties of fruits especially fruit firmness before and after harvest. Proline treatment increased fruit weight, fruit diameter, flesh firmness , TSS, peel anthocyanin content and total sugars. Furthermore, decreased fruit acidity and weight loss after storage on room temperature. In conclusion, the results of the present study recommended using the combination of salicylic acid plus calcium acetate and proline to enhance fruit quality and shelf life of peaches.

水杨酸、醋酸钙和脯氨酸在提高“早膨”桃果实品质和货架期中的应用

在2020和2021季节，研究了水杨酸、乙酸钙和脯氨酸单独或组合在采前叶面施用对“早甜”桃品种果实品质和贮藏性能的影响。结果表明，与对照处理相比，采前施用所有处理均能提高果肉硬度。水杨酸处理增加了果实的重量、大小和直径。此外，贮藏后总糖减少，果实重量减轻。结果还表明，醋酸钙处理提高了果实的理化性质，尤其是果实采前和采后的硬度。脯氨酸处理增加了果实重量、果实直径、果肉硬度、TSS、果皮花青素含量和总糖。此外，在室温下储存后，降低了水果的酸度和重量损失。总之，本研究结果建议使用水杨酸加乙酸钙和脯氨酸的组合来提高桃子的果实质量和保质期。
