Effects of Growth Promoters and Inhibitors on Cambium Activity and Formation of Reaction Wood . — The cambium activity of horizontal bent apicotyls of Aesculus hippocastanum can be stimulated by auxins (2,4‐D) or kinetin applied artificially. The effect of kinetin was equal on the upper and lower side of the stem. Applied in high concentration to the upper side 2,4‐D acted as inhibitor of cell division on this side but as promoter on the lower side. TIBA was active at the spot of application only. The formation of reaction wood was influenced remarkably by auxins but only slightly by TIBA or kinetin. The results are discussed in term of the theory of growth substances of Went and Cholodny.
