高光效育种是一个新的研究领域,目前仍处在探索性阶段,但进展较快,前途宽广。高光效育种的理论依据是,农作物的干物质中,无机成分约占10％,其余90％是依靠光合作用生成的碳水化合物及其合成物质。因此,旺盛的光合作用系统,是提高作物产量的生理基础。光合作用系统的强弱和制造物质的多少,在品种间、物种间有很大差异,通过杂交、重 High light efficiency breeding is a new research field, which is still in exploratory stage at present, but its progress is rapid and its future is broad. The theoretical basis of high light efficiency breeding is that the dry matter of crops contains about 10% inorganic components and the remaining 90% are carbohydrates and their synthetic materials that are generated by photosynthesis. Therefore, a vigorous photosynthesis system is the physiological basis for increasing crop yields. The strength of photosynthesis system and the amount of manufacturing substances, in the species, there are great differences between species, by hybridization, heavy
