The majority of mature fruit are located usually on the basal portion of the lowest branches, and results of Middleton and Harvey (55) in- dicate that there is a tendency for immature fruit and "pops" (fruits with aborted embryoes) to occur farther out on the branches. Roots The peanut plant has a well-developed tap-root system, similar to that of beans or peas, with numerous lateral branches extending a con- siderable distance in the soil. Several workers (17, 58, 63, 68, 88,) have made a careful study of the root system. The soft, fleshy, fragile roots col- lapse and dry quickly when removed from the soil. This tends to give the impression that the root system of the peanut is relatively Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Arant, F.
