Abstract
The growth of groundnuts during the pre-flowering stage was varied by shading treatments that influenced subsequent growth and development by varying the establishment of the reproductive sink. Depending on the extent of the decrease in early growth the duration, or rate, of the pod initiation process was varied. Although reproductive growth was influenced by early growth, this was favored at the expense of vegetative growth. Defoliation was inversely related to the reproductive sink established, indicating that the plant may experience N shortages in the same way as soybeans. The loss of mass from the stems was also greatest in the crop with the largest reproductive sink, indicating that the crop may utilize stored assimilates to meet shortages if they occur. The crop studied was, in normal circumstances, unable to grow all the pods initiated to full size.
