作物产量来源于光合作用,提高光合作用效率是增加作物产量的有效途径。自然界植物的光合效率有很大差异,一般认为 C_4植物比 C_3植物的光合效率高,光呼吸强度低,Co_2补偿点低,有利于积累干物质。同时,C_3植物的不同品种或同一品种不同个体之间在这方面也不同程度的存在着差异。从上述基本事实出发,近几年我们利用 C_3、C_4植物同室效应筛选法,
Crop yield comes from photosynthesis, improve photosynthesis efficiency is an effective way to increase crop yield. The photosynthetic efficiency of plants in nature is very different. C_4 plants are generally considered to have higher photosynthetic efficiency, lower photorespiration intensity and lower Co2 compensation point than C_3 plants, which is good for the accumulation of dry matter. In the meantime, different varieties of C_3 plants or different individuals of the same variety differ in this respect to some extent. Starting from the above basic facts, in recent years we use C_3, C_4 plants with room effect screening method,
