许多试验证明,作物的物质生产,受光合作用部位(源)和消费、贮藏其产物的部位(库)的能力的相互关系所制约,而且无论哪一方都限制另一方的潜在能力。同时,源和库的关系是复杂的,做为光合产物输送途径的维管束,它影响、限制着输送速度,而且,按其联系状态,特定的源和库可形成一个源——库系统。我们曾经指出,马铃薯之所以是生产性能
Numerous experiments have demonstrated that the material production of crops is governed by the interrelationship between the photosynthetic site (source) and the ability to consume, store the product’s locus (pool), and wherever the other side limits the potential capacity of the other. At the same time, the relationship between the source and the reservoir is complex, acting as a bundle of photosynthetic transport pathways that influence and limit the rate of transport and, depending on the state of contact, the particular source and sink can form a source-sink system. We have pointed out that the reason why potatoes are productive
