摘要
对我国南方梨优势产区主栽33个品种88份样品进行了采样调查。结果显示:南方梨果集中成熟期为7月下旬,占45.57%;砧木选择以豆梨为主,占52.56%;果皮分为绿皮和褐皮两大类,早美酥、初夏绿、5-18等品种果锈极少、果点小;果形指数0.78～1.04,平均值0.90;平均单果重128.0～660.0 g,平均值264.5 g,湖北宣恩椒园镇黄坪村的秋黄单果重最大。果肉硬度1.72～5.09 kg/cm2,平均值2.80 kg/cm2;每百克果肉石细胞含量0.055～0.965 g,平均值0.259 g,湖北砂梨圃德胜香石细胞含量最低;可溶性固形物含量8.46%～13.61%,平均值11.54%,国家果树资源武昌砂梨圃丰水含量最高;可溶性糖含量变化范围为5.86%～10.06%,平均值7.6%,湖北宣恩县椒园黄坪村秋黄含量最高;可滴定酸含量变化范围为0.09%～0.27%,平均值0.14%,湖北应城市松林岗林果基地金水2号含量最高;糖酸比变化范围为26.7～100.6,平均值为58.14,湖北宣恩县椒园黄坪村的秋黄糖酸比最高,风味甜。
88 samples of 33 pear cultivars in the South China area were investigated.The results showed that the concentration mature period was in late July,accounting for 45.57 %;P.calleryana Decne was chief rootstock,accounting for 52.56 %;Pericarp color was green and brown and Zaomeisu,Chuxialv,5-18 and other varieties had few fruit rust and small fruit dot.Mean value and varying range of fruit shape index,fruit weight,flesh firmness,stone cell content per 100 g fresh weight,soluble solids content,soluble sugar content,titrable acidity,the ratio of soluble sugar content to titrable acidity were 0.462 g /0.020-1.479 g,0.90 /0.78-1.04,264.5 g /128.0-660.0 g,2.80 kg/cm2 /1.72-5.09 kg/cm2,0.259g /0.055-0.965 g,11.54 % /8.46 %-13.61 %,7.6 %/5.86 %-10.06 %,0.14% /0.09%-0.27%,58.14/26.7-100.6,respectively.Then the distribution of characters was analyzed and excellent varieties were screened out.
