The water soaked symptom of melon (Cucumis melo L.) fruits was studied.1.Temporary shading during the rapid growth of melon fruit induced the occurrence of water soaked symptom.2.The grade of symptom was different from varieties, i.e.it appeared heavily in 'Andesu' but not in 'Ruster'.3.Sucrose accumulation in the fruit was greatly inhibited by shading, while hexose accumulation was not inhibited.4.Acetaldehyde and ethanol concentrations increased under shading condition.5.Ethylene production was also accelerated under shading condition with concomitant decrease in fruit hardiness.6.Both defoliation and over loading did not induce the water soaked symptom.7.ABA sprayd on leaves accelerated the softening of fruit and ethylene production.

甜瓜（Cucumis梅洛L.）结果表明：1.在甜瓜果实快速生长期进行短暂的遮光处理，可诱导甜瓜发生水浸伤; 2.不同品种的症状轻重不同，i.e.it‘安德苏’发病严重，‘鲁斯特’发病不严重; 3.遮光处理显著抑制了果实中蔗糖的积累，遮光处理提高了乙醛和乙醇的浓度，促进了乙烯的产生，但对乙烯的积累没有明显的影响6.去叶和超载处理均未引起果实的水浸伤; 7.叶面喷施ABA促进了果实的软化和乙烯释放。
