Description

The interaction of BCB and gibberellin was investigated in potato, wheat, and kidney bean (long variety) plants. In the potato, 250 ml of 10-2 or 10-3 M BCB solution was soaked into the soil in a 1/5000 are Wagner's pot, and gibberellin solution at a concentration of 10, 1, or 0.1 p.p.m was sprayed three times. As a result, BCB inhibited the stem elongation and gibberellin accelerated it, and an antagonism between BCB and gibberellin was observed. In the wheat, 250 ml of 1/2×10-2 or 10-3 M BCB solution and gibberellin at a concentration of 10 or 1 p.p.m. were applied in the same way as the dosage for potato plants. BCB shortened the leaf length and increased the number of tillers, but gibberellin elongated the leaf and did not increase the number of tillers, and an antagonism between both chemicals was observed. In the kidney bean, 180 ml of 10-2, 1/2×10-2, or 10-3 M BCB solution was soaked into the soil in a 7 inches clay pot, and gibberellin at a concentration of 10, 1, or 0.1 p.p.m. was sprayed two times. As a result, the stems treated with 10-2M BCB failed to elongate, and gibberellin removed the inhibition by BCB.
