提高作物光合作用途径的研究现状

Progress to Improve Photosynthesis Methods of Crops

光合作用是重要的生物合成过程,也是栽培作物产量形成的基础。C3作物光呼吸高,光合速率低。如何提高光合效率,一直是植物学界研究的重大课题,对喷施亚硫酸氢钠、碳肥、钾营养、遗传改造等途径来提高C3作物光合作用的研究现状进行了综述,以期为提高C3作物光合作用研究提供参考。

Photosynthesis is an important biosynthetieal reaction and the base of yield. Photorespiration of C3 crops is high, but photosynthesis is low. How to improve photosynthesis is always an important task of botany research. Now research harvest was obtained. Effects of NaHSO3, CO2, potassium on photosynthesis of crops were discussed, and transformation of C3 crops＇ hereditary features was also discussed according to C4 pathway mechanism.
