| 摘 要： | 为探讨适用于高温高湿地区的火龙果果袋,以红皮红肉型‘桂红龙2号’火龙果为材料,测定5种不同类型果袋套袋后袋内温湿度日变化及对火龙果果实品质、果实病害以及采后果实失水率等的影响。结果表明,套袋后袋内温度升高速度更快,白天袋内温度均显著高于对照;套袋使果皮变薄,增加可食率,促进了果皮鳞片转红,以牛皮纸袋为最高;套袋显著增加了果皮与果肉的色素含量;显著增加了果实可溶性固形物含量,不同程度的提高了葡萄糖和果糖的含量;但套袋也提高了果实苹果酸及柠檬酸的含量。套袋总体上降低了采后水分散失的程度,白色纸袋和无纺布袋有利于降低采后病害发生率,延长货架期。除黑色尼龙网袋以外,套袋均提高了果实煤烟病的发病率。综上,在广西南宁周边高温高湿地区,可使用黑色尼龙网袋,有利于防止鸟啄和虫害,或使用白色纸袋和无纺布袋,有利于延长货架寿命,但采收后要注意煤烟斑的清洗。

| Abstract: | The diurnal variation of temperature and humidity in five different types of fruit bags and their effects on fruit quality,fruit diseases and water loss after harvest of pitaya fruit were analyzed to select suitable fruit bags for pitaya fruit in high temperature and wetland areas.The red-skin and red-flesh type‘Guihonglong 2’pitaya fruit was used as the material in the experiment.The temperature in the bag increased faster after bagging,and the temperature in the bag during the day was significantly higher than that in the control group.The bagging made the peel thinner,edible rate increased,and scales turn red.The effect of kraft paper bags was the best.Bagging significantly increased the content of pigments in the pericarp and pulp,significantly increased the content of soluble solids,increased the content of glucose and fructose in different degrees,and also increased the content of malic acid and citric acid.Bagging generally reduced the degree of water loss after harvest.White paper bags and non-woven bags were helpful to reducing the incidence of postharvest diseases.Except black nylon net bags,other bagging increased the incidence of sooty moulds in fruits.In conclusion,black nylon mesh bags or white paper bags and non-woven bags could be used in high temperature and high humidity areas around Nanning,Guangxi,which could prevent bird pecking and insect damage,or white paper bags and non-woven bags could be used to prolong shelf life.However,it is necessary to clean the mildew after harvest. |
