उत्तर
Plant hormones often work in combination. Some plant hormones may have antagonistic effects, while others may have augmentative effects. It is almost impossible to pinpoint any single hormone for a particular effect in a plant part. Moreover, plant hormones bring out their effect in coordination with various extrinsic factors. Hence, it is difficult to assign any effect seen to any kind of hormone.
