摘　　要：为了给黑莓品种的鉴定和栽培措施的制定提供科学依据,对11个黑莓品种在南京地区的生长情况进行了调查和分析。结果发现,黑莓功能叶片中叶绿素含量平均为(40.87±4.84)spad,同一品种在不同生长期其叶绿素含量比较稳定,而不同品种却存在着较大的差异。复叶大小平均为(1.51±0.25)dm2,品种间差异显著,其中Chester品种的最大,Triple Crown的最小,前者是后者的1.65倍。小叶数量和单株叶面积分别平均为(4 815±3 880)片和(7.65±5.94)m2,品种间差异极显著,其中Kiowa品种的叶片数量最多,其单株叶面积最大,单株叶面积平均为(22.92±6.72)m2,远远高于其它品种。枝蔓数量和年生长量分别平均为(26.32±10.92)支和(2.14±1.52)dm3,品种间差异也达到了极显著水平,枝蔓发生数量最多的品种也是Kiowa,最少的品种是Young,后者数量不到前者的1/4;Kiowa和Triple Crown这2个品种的枝蔓年生长量最大,Young品种的年生长量最小,前者是后者的10余倍。In order to provide a scientific basis for cultivar identification and cultivation of blackberry,growth performance of 11 blackberry cultivars in Nanjing was investigated and analyzed.The results showed that average content of chlorophyll in functional leaves was（40.87±4.84） spad,and chlorophyll content in a cultivar was stable at different growth period.But there were great differences between chlorophyll contents in 11 blackberry cultivars.Average size of compound leaves was（1.51±0.25） dm2,and the differences between cultivars were significant.The size of leave in Chester with the maximum value was 1.65 times that in Triple Crown with the minimum value.Average number of leaflets was（4 815±3 880）,average leaf area per plant was（7.65±5.94） m2,and the differences between cultivars were very significant.Leaf area per plant in Kiowa with the most leaflets was the biggest,up to（22.92±6.72） m2,which was far higher than that in the other cultivars.Number of branches and tendrils was（26.32±10.92）,annual increment was（2.14±1.52） dm3,and the differences between cultivars were very significant.The number of branches and tendrils of Young with the minimum value was not up to a quarter of that of Kiowa with the maximum value.The annual increments of Kiowa and Triple Crown with the maximum value were over 10 times than that of Young with the minimum value.
