摘要
通过定期采摘大果红山茶果实,分别测定了其横纵径、干重、油脂含量及脂肪酸含量,以了解其果实发育特性。结果表明:大果红山茶在果实发育早期茶果迅速膨大,直至7月下旬果实大小基本确定。果实干物质的积累总体上呈线性增长,其中茶籽干物质的积累在6月下旬至10月下旬进行。茶籽从7月下旬开始积累油脂,茶籽含油率呈直线增长,收获时可达29.72%。随着果实发育,茶籽油中各种脂肪酸的相对含量有所变化。其中含量不断增大的是油酸和硬脂酸,含量不断降低的主要有棕榈酸和亚油酸,总体上不饱和脂肪酸的含量不断增加,饱和脂肪酸的含量则相应下降。
In order to understand the development characteristics of the fruit of Cammellia magnocarpa, the fruits were periodically picked and the transverse and longitudinal diameter, dry weight, oil content and fatty acids content of the fruits were measured. The results showed that the fruit shape of C. magnocarpa expanded rapidly in the early period of fruit development, and the fruit size would no longer change after late July. The fruit dry matter kept basically linearly growing, and the seed dry matter accumulated from late June to late October. The seed oil accumulated from late July to late October as well. The seed oil content showed a linear growth and was up to 29.72% when it came to harvest. The content of various fatty acids in seed oil changed with fruit growing. The content of oleic acid and stearic acid increased while the content of palmitic acid and linoleic acid decreased. On the whole, the content of unsaturated fatty acids increased while the content of saturated fatty acids decreased accordingly.
