Effects of ethephon on heartwood formation and related physiological indices of Dalbergia odorifera T. Chen.

ABSTRACT:

Introduction

Dalbergia odorifera T. Chen, known as fragrant rosewood, is a rare and endangered tree species. Studies have shown that plant growth regulators can effectively promote heartwood formation. This study aimed to investigate the effects of ethephon (ETH) on heartwood formation and the influence of ethephon and hydrogen peroxide (H₂O₂) on the physiological characteristics in D. odorifera.

Methods

D. odorifera branches underwent treatment with 2.5% plant growth regulators, including ETH, jasmonic acid (JA), salicylic acid (SA), abscisic acid (ABA), H₂O₂, and inhibitors such as ascorbic acid (AsA) to inhibit H₂O₂ synthesis, and (S) -trans 2-amino-4 - (2-aminoethoxy) -3-butene (AVG) t
