作者通过对两性花双优山葡萄果实氨基酸的研究，从试验得知：同一品种在不同地区栽培其氨基酸的总量及各种氨基酸量不同。但在各地方果实中氨基酸的分配基本规律是一致的：种子含量为最高，果皮其次，果肉最低。各部位氨基酸的大小值：种子为１０．４４５—８．４７５，果皮为６．４０７—２．８８２，果肉为４．６１８—２．５６４。 Through the study on the amino acids of the grape fruit of the both sexes, we know from the experiment that the total amount of amino acids cultivated by the same species in different regions and the amount of various amino acids are different. However, the distribution of amino acids in the fruits of all localities is consistent with the basic rules: the highest seed content, followed by the skin, the lowest pulp. The amino acid size of each site: the seed is 10.445-8.475, the pericarp is 6.407-2.882, the flesh is 4.618-2.564.
