湖南山茶属植物种质资源调查、收集和利用的研究

调查研究表明:湖南山茶属植物种质资源极为丰富,种类由原来的29种,增加到现在的52种,特有种由原来的4种,增加到12种,发现了湖南白山茶、小红花茶和假长果连芯茶3新种和变色小红花茶1变种。山茶属植物较为集中地分布于湖南南部和西南部,向东西扩散而逐渐减少;我们对41种进行了果实性状、种子含油率、油脂理化性质、油脂脂肪酸组成及其规律等分析,其结果表明:山茶属植物油脂含量丰富、质好,无污染,耐贮藏,是理想的食用和工业用油,具有较高经济利用价值。首次发现山茶属植物油脂中含有廿二碳烯酸。

INVESTIGATION COLLECTION AND UTILIZATION OF CAMELLIA GERMPLASM RESOURCES IN HUNAN

Investigations have indicated that germplasm resources in Camellia are very rich. The species have increased from 29 to 52, the characteristic species increased from 4 to 12, in which 3 new taxa and 1 variety have been discovered. The characteristics of fruits, oil content of seeds, physicchemical properties of fats and oils in 41 Camellia species have been analyzed. The results have shown that the oils and fats of Camellia are very rich in content, which have good quality, pollutionless excellent storage properties as well as higher economic value both in human daily life and machinery. Docosa-enoic acid discovered in fats and oils of Camellia plants is first reported in our paper.
