Analysis on morphology and content of nutrient components of Actinidia polygama fruit

Morphology of Actinidiapolygama （Sieb. et Zucc.） Maxim. fruit, contents of Vc, total sugar, reducing sugar and total acids, and contents of Zn, Ca, Fe, K, Mg, P and Se in its peeled fruit were determined. The results show that its fruit appears oral, the top has a beak with an average length of 39.38 mm, long and short diameters of 14.78 and 13.60 mm at the maximum cross section, respectively. Weight of per fruit is small only with a value of 5.52 g. Contents of Vc, total sugar and reducing sugar are 0. 82,384.60 and 102.90 g · kg-1 , respectively, content of total acids is 2.24%. Contents of P, Ca, K and Mg are 0.31,0.44, 2.82 and 0.26 mg· g-1 , respectively, while those of Fe, Zn and Se are 8.83, 3.45 and O. 10 μg · g-l, respectively. It is suggested that A. polygama fruit appears gorgeous color, and riches in Vc and mineral elements, so it is a kind of wild fruit with edible and ornamental values.
