三叶木通果实生物学特性及营养成分的研究

STUDIES ON BIOLOGICAL CHARACTERISTICS AND NUTRIENTS OF FRUIT IN THREE-LEAF AKEBIA

本文报道了陕西省野生三叶木通果实的生物学特性及营养成分。三叶木通座果率低。落果高峰在5月下旬,以短缩枝结果为主;果实纵横径生长呈双S曲线,食用部分是发达胎座;果实类型有紫红皮和黄褐皮,或随圆形和卵圆形。成熟果实富含矿物质,可溶性糖主要是果糖,有机酸主要是乳酸,蛋白质氨基酸主要是谷氨酸、天门冬氨酸、赖氨酸和亮氨酸。脂肪酸主要是油酸和亚油酸。种子脂肪酸主要是油酸。果实可食率低。

This paper reports biological characteristics and nutrients in fruit of wild Three-leaf Akebia (Akebia trifotiata Koidz.) in Shaanxi province. The percentage of fertile fruit is low. Heavy fruit-falling occurres in late May. Fruiting is mainly in spur. Fruit shows a double signoid growth curve from blossom falling to maturity in length 'and width. Developed trophosperm is edible. Mature fruit is rich in minerals. The main sugar is levulose, the main organic acid is milk acid; the amino acids decomposed from protein are glutamic acid, aspartic acid, lysin and ieucine; the fatty acids from fat are oleic acid and linoleic acid. Seed fatty acid is mainly oleic acid. The percentage of esculent part of fruit is low.
