This study was conducted to test the possibility of using leaf extracts of invasive weed tree-of-heaven (Ailanthus altissima (Mill.) Swingle) for the postharvest quality preservation of apricot (cv. ‘Şalak’) fruits. Two different doses of A. altissima leaf extracts (0.5% and 2.5%) with and without supplements (0.1% g Arabic gum, 0.05% citric acid, 0.05% potassium sorbate and 0.05% ascorbic acid) were tested. Results showed that the extracts of A. altissima leaves have strong ability to prevent weight loss, reduce decay incidence, protect visual quality, delay the occurrence of chilling injury, keep fruit firmness and delay the reduction in ascorbic acid content.

进行这项研究的目的是测试使用入侵性杂草天堂树（Ailanthus altissima（Mill。）Swingle）的叶子提取物进行杏（cv。'alalak'）果实收获后品质保存的可能性。测试了两种不同剂量的带有和不带有补充剂（0.1％g阿拉伯树胶，0.05％柠檬酸，0.05％山梨酸钾和0.05％抗坏血酸）的拟南芥叶提取物（0.5％和2.5％）。结果表明，A。altissima叶片的提取物具有很强的防止体重减轻，减少腐烂发生，保护视觉品质，延缓冷害发生，保持果实坚硬和延缓抗坏血酸含量减少的能力。
