| 摘要: |
| 【目的】研究薄皮甜瓜果实套袋后袋内小气候环境的日变化和不同果袋对果实品质的影响，筛选出适宜薄皮甜瓜的果袋。【方法】以硫酸纸袋、牛皮纸袋、白色塑料袋、红色塑料袋、蓝色塑料袋、绿色塑料袋、黑色塑料袋7种透光率不同的果袋，对薄皮甜瓜品种“绿魁”的果实进行套袋处理，首先采用照度计对套袋材料的透光率进行测定，然后在试验中对果实袋内微域环境的日变化进行测定，最后在果实采收适期利用HPLC等方法对果实品质进行测定。【结果】套袋果实袋内微域环境的日变化与果袋的透光率有明显联系，透光率高，袋内的光照强度、温度相对也较高，CO2含量和袋内的相对湿度则较低。果实品质也受果袋材料透光率的影响，透光率越高，果实颜色越深，可溶性糖、可溶性蛋白、游离氨基酸、VC、可溶性固形物和总糖含量相对越高，而有机酸含量反之。【结论】白色塑料袋和硫酸纸袋对薄皮甜瓜果实品质相对较好，但从环保角度考虑，建议在生产中采用硫酸纸袋进行薄皮甜瓜套袋。 |

| Abstract: |
| 【Objective】Daily variation of microenvironment and effects of bagging materials on fruit quality were researched to select suitable bags.【Method】Oriental melon ‘Lükui’ was bagged by different bags including sulfuric acid paper,kraft paper sacks,white plastic bag,red plastic bag,blue plastic bag,green plastic bag,and black plastic bag.Transmittance of bagging materials was determined by illuminance meter at first,then the daily variation of microclimate environment was measured,and the fruit quality was determined by HPLC in harvest period.【Result】There was significant connection between daily variation of microenvironment and transmittance of bagging materials.Higher light transmittance led to higher light intensity and temperature,but lower CO2 concentration and relative humidity.Fruit quality was also affected by transmittance of bagging materials.Higher transmittance caused deeper fruit color,higher contents of soluble sugar,soluble protein,free amino acid content,vitamin C,soluble solids and total sugar,and lower organic acid content.【Conclusion】Quality of oriental melon bagged with white plastic bag and sulfuric acid paper was better.Sulfuric acid paper is suggested to use for oriental melon bagging considering environmental protection. |
