Этефон, предшественник этилена, значительно замедлял осаждение амилопластов, выполняющих функцию статолитов в клетках, что коррелирует с его ингибирующим действием на формирование гравитропического изгиба стебля.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>растения томата (Solanum lycopersicum L.)</kwd><kwd>листья</kwd><kwd>гравитропизм</kwd><kwd>этилен</kwd><kwd>эпин</kwd><kwd>статоциты</kwd><kwd>статолиты</kwd><kwd>амилопласты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tomato (Solanum lycopersicum L.)</kwd><kwd>leaves</kwd><kwd>gravitropism</kwd><kwd>ethylene</kwd><kwd>epin</kwd><kwd>statocytes</kwd><kwd>statolites</kwd><kwd>amyloplasts</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Molecular mechanisms of gravity perception and signal transduction in plants / Y.
