1.试验分析了原产三个地区的二十八个大豆地方品种和原产杭州的三个地方品种在全国八个地区的地理播种试验,以及在杭州地区两个大豆品种的播种期试验所获得生化成分的资料。初步明确大豆系统发育和个体发育所经历的气候条件是决定大豆种子生化成分的主要因素。2.从分析原产三个地区二十八个的大豆地方品种的生化成分表明,凡原产于高纬度地区的品种,其蛋白质含量较低,油分含量较高,碘价亦较高;而原产于低纬度地区的品种,其生化成分则反之。由此可以认为,大豆生化成分的品种特性,是在不同气候条件下系统发育过程中所形成的遗传特性之一。3.从杭州原产的三个地方品种在全国八个地区的大豆地理播种试验的结果表明,同一品种,凡播种于高纬度地区的,其蛋白质含量较低,油分含量较高,碘价亦较高;而播种于低纬度地区的则有相反的趋势。可以推断,大豆个体发育过程中的生境条件也是影响大豆种子生化成分的主要因素。4.以两个大豆品种在杭州举行播种期试验的结果表明,播种较早的蛋白质含量较高,油分含量较低,碘价亦较低;而晚播的有相反的趋势。由此可以说明,栽培季节的气候变化也和地区性气候差异一样,能影响大豆生化成分的含量。5.研究气候条件和大豆生化成分的关系,并揭示其变化规律,对全国大豆生产的合理布局,具有
1. The experiment analyzed the seeding test of 28 soybean native breeds and 3 native Hangzhou breeds originating from three regions in the country in eight regions of China and the sowing date test of two soybean varieties in Hangzhou area Access to biochemical components of the information. It is the main factor to determine the biochemical composition of soybean seed that the climatic conditions experienced by the initial clarification of soybean system development and individual development. From the analysis of the biochemical composition of 28 local soybean varieties in three regions of origin, it indicates that the varieties with high protein content, high oil content and high iodine value, Originated in the low latitudes of the species, the biochemical composition is the opposite. Therefore, it can be considered that the variety characteristics of biochemical components of soybean are one of the genetic characteristics formed during the phylogeny under different climatic conditions. The results of sowing experiment of soybean from three local Hangzhou native cultivars in eight regions of China showed that the same variety, where sown at high latitudes, had lower protein content, higher oil content and iodine price Higher; and sowing in low latitudes there is the opposite trend. It can be inferred that the habitat conditions during the development of soybean are also the main factors affecting the biochemical composition of soybean seeds. The results of sowing date test of two soybean cultivars in Hangzhou showed that the earlier the sowing was, the higher the protein content, the lower the oil content and the lower the iodine value, while the late sowing had the opposite trend. This shows that the climate change in the cultivation season is also affected by regional climate differences and can affect the biochemical composition of soybean. 5. Study the relationship between climatic conditions and biochemical composition of soybeans, and reveal the law of change, the rational layout of the national soybean production, with
