Description
Yuan-Jing Zhu and co-authors test whether a plant hormone spray can coax a prized rosewood into making its valuable heartwood faster. The tree, Dalbergia odorifera, is rare and endangered, and its fragrant heartwood forms slowly. Branches were treated with several growth regulators and related chemicals, including ethephon. After fourteen days the team checked how far the heartwood material extended, how blocked the vessels were, and how much of a key aromatic compound formed.
Ethephon won clearly: the treated zone stretched 15 centimetres, and the aromatic compound reached fifteen times the level of the weakest comparison group. Ethephon and hydrogen peroxide both spurred the tree's own ethylene production, and protein levels and enzyme activity rose after treatment. The study, published in 2023, presents ethephon as the strongest promoter that does not hinder the tree's growth.
