在夏威夷,番木瓜易受果蝇侵害,成熟果比绿熟果受害率可增加3倍。业已证实,果蝇的卵和幼虫长时间处于10℃以下低温便无法存活。然而,在10—12℃以下的温度,番木瓜果实只能贮藏7天左右。有资料指出,鳄梨,番木瓜、甜瓜之类的呼吸跃变型水果,在后熟期间,对低温敏感性降低。本试验旨在确定冷藏处理能否作为番木瓜果实免受蝇害的一种方法,并确定冷害发生的温度与不同成熟阶段的果实放置时间之间的关系。同时还进行了以采后处理方法来减轻冷害的试验。
Papaya is susceptible to fruit flies in Hawaii, with a three-fold increase in the incidence of mature fruit over green ripe fruit. It has been confirmed that eggs and larvae of Drosophila can not survive for long periods of time at cryogenic temperatures below 10 ° C. However, at temperatures below 10-12 ° C, papaya fruits can only be stored for about 7 days. Data indicate that avocado, papaya, melon and other breath-jump type of fruit, during ripening, lower sensitivity to hypothermia. The purpose of this experiment was to determine if chilled treatment can be used as a method of preventing fly damage in papaya fruits and to determine the relationship between the temperature at which chilling injury occurs and the fruit placement time at different maturation stages. At the same time also conducted a post-harvest treatment to reduce chilling injury test.
