我国主要红花油茶果的经济性状研究

为系统研究我国主要红花油茶果的品种品质,选取德兴、腾冲、广宁3种红花油茶果为原料,测定果皮厚度、果直径、内壳厚度、籽直径、单果重、鲜出籽率、鲜出仁率、籽含油率和仁含油率9项主要经济性状指标,采用方差分析、变异性分析、相关性分析、回归分析和主成分分析5种统计学方法进行数据处理.结果表明,3种红花油茶果实的各经济性状指标差异极显著,其中,德兴红花油茶与腾冲红花油茶只有内壳厚度与籽直径差异显著,但与广宁红花油茶所有指标都差异显著,而腾冲红花油茶与广宁红花油茶则只有内壳厚度与籽直径差异不显著;3种红花油茶的鲜出仁率与鲜出籽率呈极显著线性正相关,3个品种中出籽出仁率最高的是腾冲红花油茶,出油率最高的是德兴红花油茶.

Research on economic traits of main Camellia chekiangoleosa Hu in China

Camellia chekiangoleosa Hu from Dexing, Tengchong and Guangning were selected as materials to study systematically qualities of main C. chekiangoleosa Hu in China. 9 main economic trait indexes, including pericarp thickness, fruit diameter, inner shell thickness, seed diameter, fruit weight, fresh seed yield, fresh kenel yield, seed oil content and kenel oil content were determined. ANOVA, variability analysis, correlation analysis regression analysis and principal component analysis were used to process the tested data. According to the results, highly significant differences of every index among cultivars were found. Notable diversities of inner shell thickness and seed diameter existed between Dexing and Tengchong, while all indexes of Dexing and Guangning differed remarkably. For C. chekiangoleosa Hu of Tengchong and Guangning, differences of inner shell thickness and seed diameter were inapparent only. Significantly positive correlation was found between fresh seed and kenel yield. The highest fresh seed and kenel yields were found in Tengchong, however, fruits of Dexing had the highest oil content.
