近年来,在研究进一步提高作物产量的过程中,“源”与“库”何者是产量的主要限制因素的问题,引起了国内外许多研究者的兴趣。但不论是“源”的供应或是“库”的建造,都主要靠叶片为主的同化器官所制造的光合产物。叶的形态及机能的变化是整个植株极其复杂的生理活动的反映。它不仅受品种固有特性所制约,而且受栽培条件的影响。Evans等曾收集了世界各
In recent years, the issue of “source” and “reservoir” as major limiting factors in the production of crops in the process of further improving crop yields has aroused the interest of many researchers both at home and abroad. But whether it is the supply of “source” or the construction of “stock”, photosynthetic products are mainly made of leaf-based assimilating organs. Changes in leaf morphology and function are a reflection of the extremely complex physiological activities of the entire plant. It is not only restricted by the inherent characteristics of cultivars, but also affected by the cultivation conditions. Evans and others have collected the world
