The objective of this study was to select better varieties by evaluating characteristic of １９ tall fescue varieties during theperiod of summer stress in Nanjing .Materials and methods The site was on the farm of the Nanjing Agricultural University (１１９°１１′E , ３２°０８′N ) . Annual meantemperature is １５ .４ ℃ , w ith a range of ４３‐１４ ℃ . The mean temperature of the hottest month is ２８ .１ ℃ . The soil is a sandyloam . Sprinkler irrigation is normally applied during periods of water stress .From Sep ２００４ to Nov ２００７ , １９ tall fescue varieties were planted in a randomized complete block design with ３ replicates . Thevarieties came from China as well as foreign countries . The area of every plot was １ .３ × ２ .０m２ . The varieties were sown onNov １１th , ２００４ , at a rate of ４０g /m２ . The turf character indexes including leaf width , grow th rate , green degree , and turfapparent quality were measured from May to Oct ２００５‐２００７ .　 　 Figure 1 Mean tur f quality f rom May to Nov o f １９tall f escue varieties .Results and Conclusions Leaf width of TF１２ was significantlywider than that of TF０５ , TF０７ , TF０９ , TF１４ and TF１７ ( P ＜ ０ .０５ ) . The grow th rate appeared the following trend : Sep ＞ Aug ＞Jun ＞ Jul , The grow th rate in May and Oct was significantlyfaster than that in June and July ( P ＜ ０ .０５) . The grow th rate ofTF０３ was the highest (１１ .６８ cm /month) , TF１５ was the slowest(７ .４８ cm/month) , but differences among the other varieties werenot significant . SPAD value of TF０６ was significantly higher thanthat of TF０３ , TF０９ , TF１１ , TF１３ and TF１６ , but compared withother varieties there were not significant differences . SPAD valueof TF０３ was the minimum , and there were not significantdifferences between TF０３ and TF１１ ( Table １ ) . Seventeenvarieties except TF１８ and TF０２ were acceptable for mean turfquality during the high temperature season , , but TF０１ and TF１７were better ( Figure １) .Table 1 Grow th characteristic o f １９ tall f escue v arieties .Varieties Leaf widths( mm) Grow th rate( cm /month) SPAD valuesTF０１ x４ 佑.２４ ± ０ .１０ab ９ 鲻.３３ ± １ .２９ab ４３ z.５４ ± １ .０７abcTF０２ x４ 佑.５０ ± ０ .１７ab ９ 鲻.５０ ± １ .１５ab ４５ z.７３ ± ０ .８６abTF０３ x４ 佑.５３ ± ０ .１９ab １１ $.６８ ± １ .２９a ３８ z.９９ ± ０ .６１eTF０４ x４ 佑.４１ ± ０ .１３ab ８ 鲻.５１ ± １ .３１ab ４３ z.７１ ± ０ .８７abcTF０５ x４ 佑.０８ ± ０ .１９b ８ 鲻.９２ ± １ .０８ab ４４ z.４３ ± ０ .８７abcTF０６ x４ 佑.２０ ± ０ .１２ab ９ 鲻.４３ ± １ .１４ab ４５ z.９７ ± ０ .５７aTF０７ x４ 佑.１１ ± ０ .２１b ８ 鲻.７３ ± ０ .９８ab ４４ z.６３ ± ０ .６８abcTF０８ x４ 佑.４３ ± ０ .１４ab ８ 鲻.０５ ± ０ .９８ab ４５ z.３０ ± １ .００abTF０９ x４ 佑.００ ± ０ .２３b ９ 鲻.１６ ± １ .２６ab ４２ z.４８ ± １ .２１bcdTF１０ x４ 佑.３４ ± ０ .１９ab ９ 鲻.０６ ± １ .１２ab ４３ z.８５ ± １ .１３abcTF１１ x４ 佑.２５ ± ０ .１４ab １０ $.０４ ± １ .１５ab ３９ z.８９ ± １ .１４deTF１２ x４ 佑.６９ ± ０ .１７a １１ $.１０ ± １ .３１ab ４３ z.６８ ± ０ .８５abcTF１３ x４ 佑.２２ ± ０ .１５ab ９ 鲻.３５ ± １ .２３ab ４２ z.５９ ± １ .２６bcdTF１４ x４ 佑.００ ± ０ .１６b ９ 鲻.３３ ± １ .２６ab ４３ z.３６ ± ０ .９２abcTF１５ x４ 佑.３０ ± ０ .１７ab ７ 鲻.４８ ± ０ .８７b ４４ z.０９ ± １ .３８abcTF１６ x４ 佑.２２ ± ０ .１３ab ９ 鲻.９５ ± １ .２２ab ４１ z.８９ ± ０ .７８cdTF１７ x４ 佑.０２ ± ０ .１４b ８ 鲻.０６ ± １ .０２ab ４３ z.７８ ± ０ .９３abcTF１８ x４ 佑.３１ ± ０ .１６ab ９ 鲻.００ ± ０ .９９ab ４４ z.２９ ± １ .０１abcTF１９ x４ 佑.３５ ± ０ .１４ab ８ 鲻.４５ ± １ .００ab ４５ z.０５ ± １ .０３abcReferencesHe Yali , Hu Xuehua , Zhang Aiming , Xu Rong , Qi Jun , １９９７ .
