摘　　要：通过比较广西北部的三江、东部的岑溪和南部的南宁3个栽培区,研究了岑软2号、岑软3号2个软枝油茶(Camellia oleifera)无性系果实表型性状的地理差异。结果表明:2个无性系果实的单果质量、果径、果高、果形指数、果皮厚度、鲜籽数、鲜籽质量、鲜出籽率或千克籽数存在一定差异,其中岑软2号的果径、鲜籽质量、鲜出籽率、千克籽数及岑软3号的果高、果皮厚度、果形指数、千克籽数的差异达到了极显著。总体上南宁与岑溪栽培区之间的差异较小,而三江与其它2个栽培区之间的差异较显著。不同栽培区之间果实颜色也存在差异,呈现出青色、青绿色、青黄色和青褐色4种不同的颜色。The geographic differences of fruit phenotypic characters of clones of Cenxi soft-branch No.2 and No.3 Camellia oleifera were studied by comparing three cultivation areas of Sanjiang, Cenxi and Nanning, which lie to the： north, east and south of Guangxi province. The results showed that single fruit weight, fruit diameter, fruit height, fruit shape index （weight/diameter）, peel thickness, fresh seed number, fresh seed weight, seed ratios of fresh fruit or seed number per kg were different to some extent. The fruit diameter, fresh seed weight, seed ratios of fresh fruit and seed number per kg between Cenxi soft-branch No. 2 and Cenxi soft-branch No. 3 showed extremely significant differences. On the whole, there were less differences between the cultivation areas of Nanning and Cenxi, but more between Sanjiang and the two others. The colors of fruits were different between different cultivation areas, which were cyan, turquoise, greenish yellow and greenish brown.
