高光效育种是近年来蓬勃发展的一个新的育种领域,它吸引了许多科学研究工作者。目前,高光效育种还处于探索阶段,对有些问题看法也不尽相同,现就一些材料综合如下:一、高光效育种的概念农作物制造积累的干物质中,有90%以上是通过光合作用合成的碳水化合物及其合成物质,无机成分只占10%。农作物产量与光合面积、光合时间、光合强度、产物消耗及产物分配等光合性能有密切关系。因此,不少人从育种角度出发,着眼于改善这几个方面。概括起来有两个途径:一是从作
High light efficiency breeding is a new field of breeding that has flourished in recent years, and it attracts many researchers. At present, the high light efficiency breeding is still in the exploratory stage, the views on some issues are not the same, and now some of the material is summarized as follows: First, the concept of high light efficiency breeding Crops accumulated dry matter accumulation, more than 90% are synthesized by photosynthesis Carbohydrates and their synthetic substances, inorganic ingredients only 10%. Crop yield and photosynthetic area, photosynthetic time, photosynthetic intensity, product consumption and product distribution and other photosynthetic properties are closely related. Therefore, many people from the breeding point of view, focusing on improving these aspects. To sum up there are two ways: First, from doing
