SOLBOAIMENT During the sucvey of 1956, three plants, snap beans, lima beans and Dlack-eyed peas Ver: 2.204 .% hs Beltsville Laboratory of the U. S. Department of Agriculture. The leaf, stalk, pod and fruit of each were anelyzed separately and the snap bean and black-eyed pea samples were The results on the plants are given in Table 13, while the soil. analysis is show in Table 1h, Normalizing the data to stalk = 1, the mean Strontium Unit values for leaf, fruit and pod become 0.85, 0.52, and 0.5h, respectively. The mean Sr-89/Sr-90 ratios are 1.9, 0.2, 0.7, and 1.4 for the leaf, fruit, stalk and pod. While such averaging may not be completely justified, it would lead to the following conclusions: He Ree eee sees aeaeAEs MIO Rami oe Co cere Hiermainte eet ER ee emta run in duplicate. 1. The high stalk activity may indicate uptake that is partially blocked from the rest of the plant. 2. The leaves show higher S.U. values than the pod and fruit, indicating some leaf retention 3. - The Sr-89 values indicate that the leaf and pod activity is younger than the fruit activity. | It is also of interest to note that the Sr-89 values indicate TERInieMe et that some of the top soil activity is younger than the bottom fraction. - 37 -
