Chinese. 以“香秀”西瓜（CitrulluslanatusThunb．）为材料，研究了无纺布根域限制对西瓜果实品质的影响。结果表明：与对照组相比，根域限制处理适度提高了果实迅速膨大时期地上部光合速率，显著改善了果实的品质。根域限制处理组果实的可溶性固形物含量、出汁率、Vc含量和类黄酮含量均与对照组之间达到了极显著或显著差异的水平。高效液相色谱法分析显示，处理组与对照组西瓜果实有机酸中的草酸、苹果酸和柠檬酸含量以及酚类物质中的儿茶素和绿原酸的含量之间达到了极显著差异水平。但根域限制处理在西瓜果实的发育、果实最大横纵径、平均单果重、可滴定酸含量和番茄红素含量方面与对照组之间差异不显著。

Root restriction increased the photosynthetic rate at the fruit rapid-expanding stage and improved fruit quality,in terms of soluble solid content,juice yield,content of Vitamin c and flavonoid. The content of organic acid （oxalic acid, citric acid and malic acid） and polyphenol （catechin and chlorogenic acid） of root restriction increased significantly. There was no significantly difference in fruit development, longitudinal diameter, mean fruit weight, content of titrable acids and lycopene between non-root restriction and root restriction.
