Physiological response mechanism of <i>Machilus faberi</i> Hemsl under drought stress and rewatering.

ABSTRACT: Drought stress is a predominant environmental challenge that significantly limits plant growth and survival, particularly affecting agricultural productivity and ecological stability in arid and semi-arid regions. This study aimed to elucidate the physiological responses of one-year-old Machilus faberi Hemsl seedlings to various degrees of drought stress, thereby aiding their cultivation and application in challenging environments. To simulate real-world drought conditions, four levels of drought stress were defined based on soil moisture content: control (80% soil moisture), mild drought (LD, 50-60% soil moisture), moderate drought (MD, 40-50% soil moisture), and severe drought (SD, 20-30% soil moisture). These thresholds were selected to represent a gradient from optimal water ava
