Comparisons on Seeds of Changlin Series of Camellia oleifera at Different Elevation

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.
