摘要
对中国1598份野生大豆和1595份栽培大豆的脂肪含量进行了比较分析,发现野生大豆的脂肪含量为9.94％,明显低于栽培大豆的(19.05％)。对来自中国不同纬度的174份不同进化类型大豆进行了脂肪酸组成分析,发现随着大豆进化程度的提高,亚麻酸、棕榈酸含量逐渐降低,油酸含量逐渐增加。探索了日照长度,昼夜温度对大豆脂肪酸形成与积累的影响。发现了一批特异基因型。
The fat content of 1598 wild soybeans (G. soja) from different regions of China was 9.94% on thd average and lower significantly than that of 1595 cultivated soybeans (G. max), which was averaged19. 05%. The results of fatty acid composition of 174 wild, semi- wild (G. gracilis) and cultivated soybeans showed that the linolenic and palmitic acid con- tent decreased, while the oleic acid content increased as the soybean evoluted from wild to cultivated type. The effect of photoperiod and day and night temperature on fatty acid com- position was analyzed. Some special genotypes, such as the linolenic content as high as 23. 12%, the linoleic acid content as high as 61. 24%, the oleic acid content as high as 51.55%, and the palmitic acid content as high as 15.49, were discovered in Chinese wild soybean germplasm.
