Abstract
The sedimentaion of amyloplasts in tomato leaf petiole cells, when influenced by gravistimulation, gravistimulation and phytohormone epine, gravistimulation, and by an exogenous source of ethylene ethephon for a period of 0.25–24 h, was demonstrated. Ethephone significantly slowed down the sedimentation of amyloplasts serving as statolytes in cells, which correlates with its inhibitory effect on the formation of the gravitropic bending of the stem.
