In crop plants, the physiological basis of dry matter production is dependent on the source-sink concept, where the source is the potential capacity for photosynthesis and the sink is the potential capacity to utilize the photosynthetic products. If the sink issmall, the yield cannot be high; and even if the sink is large, the yield cannot be high if the source capacity is limited. Several crop plants including rice and wheat have shown changes in source and sink, during the course of domestication and evolution into modern cultivars. The modern plant type concept is essentially a blend of improved source and sink where the leaf (source) is short and erectofile to capture greater solar radiation and the sink is expanded by increased grain number and size and by profuse tillering...
