摘　　要：对11个黑莓品种在南京地区的结实性状进行了调查，发现果实成熟期、产量、果实大小等方面差异很大，达到显著至极显著水平。‘Young’和‘Boysen’2品种为早熟品种，在5月20日前后开始成熟，‘Chester’为最晚熟品种，在6月20日前后才开始成熟；‘Chester’、‘Kiowa’和‘Hull’3品种果熟期超过40d，‘Young’和‘Boysen’2品种成熟期只有20d左右；产量最高的品种是‘Kiowa’，平均为8．94kg／株，最低的品种是‘Arapaho’和‘Young’，分别只有1．19kg／株和1．22kg／株，相差7倍以上，其他品种产量从3～7kg／株不等；果重方面，‘Kiowa’品种最为突出，平均达到12．67g，最大果达到了28．27g，远远高于其他品种，果重最小的品种是‘Young’，平均只有3．96g，其他品种平均果重在5～6g。The fruit characters of 11 blackberry cultivars in Nanjing were investigated in this study. The results showed that there were significant differences in frueteseenee, yield and fruit size among the euhivars. ‘ Young＇ and ‘ Boysen＇ were the early-ripening cultivars, and began to mature about in May 20.‘Chester＇ is the late-ripening eultivar and began to mature about in June 20. The period of fruit maturity of ‘ Chester＇ , ‘Kiowa＇ , ‘ Hull＇ were over 40 days, while only 20 days for ‘Young＇ and ‘Boysen＇. The yield of ‘Kiowa＇ was the highest and the average yield was 8, 94 kg/plant. But the yield of ‘Arapaho＇ and ‘Young＇ were the lowest, only 1.19 kg and 1.22 kg per plant, respectively. For the other euhivars, the yield arranged from 3 kg to 7 kg per plant. The average single fruit weight of ‘Kiowa＇ was 12.67 g, much greater than the other＇ s. ‘ Young＇ was the smallest eultivar in single fruit weight, the average weight was only 3.96 g, and for the other eulfivars, the average weight arranged from 5 to 6 g.
