植物的绿色叶是光合作用活性器官，其能够将吸收的太阳能储存在还原的有机化合物中。这些同化物代表了必须满足植物生长和发育需要的能量和化合物的库。虽然植物的干物质生产与净叶光合作用没有很好的相关性，但高产作物必须具有高光合速率，结合能量有效的暗呼吸和有利于收获的植物器官的同化物分配。因此，农业技术的目标是在各种环境条件下保持高的总光合能力，即高同化率和量子产量。提高光合作用的灵活性也是适应和修改叶片解剖和形态的指导原则，通常由合适的叶方向，林分几何形状和密度支持（第6章）。
The green leaves of plants are photosynthetically active organs which are able to store absorbed solar energy in reduced organic compounds. These assimilates represent the pool for both energy and compounds which have to meet the plant’s requirements for growth and development. Although the dry matter production of a plant does not correlate well with net leaf photosynthesis, high-yielding crops must have high photosynthetic rates combined with energetically efficient dark respiration and assimilate partitioning which favours the harvested plant organ. Agricultural techniques therefore aim to maintain high overall photosynthetic capacity, i.e. high assimilatory rates and quantum yields, under a variety of environmental conditions. Enhancing the flexibility of photosynthesis is also the guiding principle for adaptations and modifications in leaf anatomy and morphology, generally supported by suitable leaf orientation, stand geometry and density (Chapter 6).
