中文摘要：
以红地球和玫瑰香葡萄品种为试材,以小林果袋株式会社生产的葡萄专用纸袋（本文称XL果袋）作对照,研究自主研制的聚丙烯（PP）无纺布果袋（简称PP果袋）对葡萄果实外观品质和内在品质的影响。结果表明,PP果袋可以有效地改善葡萄果穗生长的微域环境,PP果袋内部温度和湿度的变化与XL纸袋相比较温和,极端温度与湿度持续时间短,平均分别为对照的22%到45%。同时PP果袋对自然光的透过率较对照高20%。田间试验表明,PP果袋显著提高了葡萄浆果的可溶性固形物、花青苷、维生素C等的含量（P〈0.05）,同比增长约20%;显著改善了葡萄的综合鲜食品质（P〈0.05）,品尝总评指数高于对照约15%;显著提高了葡萄果实果面亮度和着色程度（P〈0.05）;显著降低了葡萄水罐、日烧、炭疽、白腐等病害的发生（P〈0.05）,同比降低40%左右。认为与纸袋相比PP果袋因优良的防水透气透光性能可以明显提高葡萄浆果的综合品质。
英文摘要：
Red Globe and Muscat Hamburg grape cultivars were used to study the effects of polypropylene（PP） bag on berry qualities with the normal paper bag as control.The results showed that the microenvironment of berries was improved in PP bags in comparison with paper bag.The changing of temperature and humidity in PP bags was more moderate than those in paper bag,and the lasting duration of extreme temperature and humidity in PP bag was shorter than that in paper bag by about 78% and 55%,respectively.Meanwhile natural light transmissivity of PP bag was higher than paper bag significantly（P〈0.05）.Both exterior and interior qualities of berries bagged with PP bags were improved significantly（P〈0.05）.The contents of soluble solid,anthocyanin and Vitamin C in the berries with PP bags increased by about 20%.The evaluation index of fresh eating quality of the berries in PP bags was higher by about15% and the disease incidence in PP bags decreased by 40%.It is suggested that PP bag can improve berry quality because of its characters of water proof,ventilation and light transmissivity in comparison with normal paper bag
