While experimentation, why do you think it is difficult to assign any affect seen to any single hormone?

Solution
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.
