摘要
本文研究结果表明,大豆蛋白质及脂肪含量高低,除受品种本身内在遗传基因控制外,还受生态区域环境因素(如地理纬度、海拔高度等)的影响。凡是环境条件有利于蛋白质形成,籽粒蛋白质含量高时,脂肪含量则相应减少;反之,环境条件有利于脂肪形成,脂肪含量增加时,蛋白质含量相应减少。 根据研究结果,初步将中国大豆品质生态区域划分为五大区,即:1.东北大豆生态区;2.黄淮海流域大豆生态区;3.长江流域大豆生态区;4.南方秋、春大豆生态区;5.西北干旱大豆生态区。
The effects of ecogeographic environments on chemical composition of soybean seeds were studied. It was shown that the protein content and oil content were not only controlled by their genetic facfors but also affected by ecogeographic enviroment and conditions (such as latitutes and altitutes) under which they were grown percent protein of soybean seed increased when the enviromental conditions were favorable to its accumulation, but oil content decreased. In contrary, if the enviroments were suitable to oil synthesis its percentage would be enhanced while protein content could be reduced.Based on the present results, soybean production area in China could be classified into following five ecological regions concerning protein and oil compositon in soybean seed 1. Northeast China eco-region , 2. Huang, Huai and Hai River Valleys eco - region, 3. Yangtze River Valley eco-region, 4. Southern Autumn and Spring sowing eco-region and 5. Northwest Drought eco-region.
