• The amount of gibberellin-like substances in seed, pod, embryo and "endosperm" of Lupinus luteus in relation to their development was studied by means of the rice seedling test. The amount of gibberellin-like substances per seed increased remarkably at the first stage of development, when the growth of seed and pod was very slow, and attained its maximum at such an early stage as the dry weight of seed reached a value of only 10 per cent and that of pod 28 per cent of their respective maximum levels. Changes in amount of gibberellin-like substances present in the pod were very closely related to the changes in growth of pod. Gibberellin-like substances equivalent to 0.3 μg gibberellin A_3 per seed and 0.028 μg Per pod were found at the 20th day after anthesis, and no activity in mature seed and 0.09 μg Per pod at the 50th day. No activity was found in the embryo itself at all stages, indicating that the gibberellin-like substances in seed occur only in the "endosperm," i. e. in the tissues that will eventually form testa in fully ripened stage.
