Determinations were conducted on seed mass of Changlin series namely Changlin No 4, No 40, No 53 and No 166 of Camellia oleifera in plantation of Qiangyuan (higher elevation) and Qingtian (lower elevation) in 2016. It showed that single fruit mass of different cultivars at higher plantation was lower than that at lower one. Analysis on composition of oil fatty acid demonstrated that content of palmitic acid, stearic acid, oleic acid and linoleic acid in seeds of tested cultivars had no evident difference between elevation. Content of cis-11-eicosenoate in unsaturated fatty acids in fruit of different cultivars at higher plantation was higher than that at lower, except Changling No 53. The experiments concluded that elevation had negative correlation with fruit size and hundred-seed weight, but had no evident correlation with oil content and composition of fatty acid.%以长林系列4个油茶Camellia oleifera Abel.品种为材料,研究了浙江省庆元县(高海拔)和青田县(低海拔)不同海拔高度对其果实大小和茶籽油脂肪酸组成的影响.结果表明,4个长林系列油茶品种的单粒重高海拔均小于低海拔;4个品种茶籽的棕榈酸、硬脂酸、油酸、亚油酸含量不同海拔之间有一定的交叉变化,但不显著.棕榈酸含量,只有长林166号和长林4号低海拔比高海拔高,硬脂酸含量除长林166号,高海拔比低海拔高;饱和脂肪酸总量高海拔比低海拔高.亚油酸含量长林166号和长林40号高海拔比低海拔低,长林4号和长林53号高海拔比低海拔高;油酸含量4个品种基本上是高海拔比低海拔低,而棕榈油酸长林166号和长林4号高海拔比低海拔高.不饱和脂肪酸中顺-11-二十碳烯酸,除长林53号,其余品种都是高海拔比低海拔高.研究结果表明,海拔高度与油茶果实的大小及百粒重呈负相关,但对含油率和脂肪酸组成的影响不明显.
