采收后的苹果仍进行正常的呼吸作用。呼吸旺盛,消耗的营养物质多,缩短贮藏寿命。苹果经涂料和特制的保鲜纸处理后,可阻碍果实的气体交换,使呼吸作用下降,水分蒸发(即自然损耗)减少,CO_2积累相应提高:因涂料和保鲜
The harvested apple still has normal respiration. Breathing, consuming more nutrients, shorten the shelf life. After the apple is coated with paint and special plastic wrap, it can hinder the gas exchange of the fruit, reducing the respiration, reducing the evaporation of water (ie natural loss) and increasing the accumulation of CO 2: due to the coating and preservation
