[Objective]The present experiment was conducted to analyze the cultivation characteristics and fruit quali-ty of nine introduced table grape cultivars in Nanning,in order to provide reference for screening suitable table grape culti-var to cultivate in southern area of Guangxi.[Method]The phenophase and growth characteristics of nine table grape culti-vars introduced in Nanning were observed through field observation,including Guanghui,Red Barbra,Zhuosexiang,Zao-heibao,Rizamat,Goldfinger,Moldova,Yellow Italy and Lover. And fruit quality was determined and analyzed in laboratory.[Result]Among the nine introduced table grape cultivars,Yellow Italy,Guanghui,Moldova and Zhuosexiang performed better growth adaptability and bearing habit;their germination rates and bearing branch rates were above 80.0%. However, for the rest five cultivars,flower formations were difficult,and the bearing branch rates were below 60.0%. For the fruit quality,Yellow Italy showed fine comprehensive quality,with soluble solid content reaching 17.36% and total sugar content reaching 254.53 mg/mL. Guanghui exhibited big berry which was 9.99 g and uniform clusters. Zhuosexiang per-formed unique aroma. However,the soluble solid contents of Guanghui,Moldova and Zhuosexiang were low,which was around 15.00%.[Conclusion]Yellow Italy exhibits the most outstanding cultivation characters and fruit quality and can be promoted widely as medium-late maturing cultivar in southern area of Guangxi. Guanghui,Moldova and Zhuosexiang all perform good cultivation characteristics. Guanghui and Moldova can be promoted properly in southern area of Guangxi as early maturing cultivar and medium-late maturing cultivar respectively. Zhuosexiang can be planted in small scale with other main cultivars as early maturing cultivar with characteristics. Red Barbra,Zaoheibao,Rizamat,Goldfinger and Lover are not recommended for promotion and plantation in south area of Guangxi.

[Objective] To study the quality differences between summer fruits and winter fruits of Shine Muscat in Nanning Area at different pruning periods.[Method] The summer fruits of Shine Muscat pruned on February 5th and winter fruits pruned on August 20th and August 29th were taken as the test materials.The panicle weight,single grain weight,soluble solids,total sugar,titratable acid,ratio of acid to solid,and Vc were determined.Quality differences between the summer and winter fruits at different pruning periods were analyzed.[Result] Under the mode of double harvest every year,the quality of the summer fruits were superior than that of winter fruits.The soluble solids,total sugar and Vc content of summer fruits were higher than those of winter fruits.The Vc and solid acid ratio of Shine Muscat pruned on August 29th were higher than those on August 20th,and the titratable acid content was lower.[Conclusion] This research provided theoretical foundation for the enhancement of fruit quality under the mode of double harvest every year.
