Exogenous melatonin on photosynthesis and physiological characteristics in maize under drought stress.

BMC plant biology - 28 Jan 2026

Noor Hafeez, Sheng Kuang

Abstract excerpt

BACKGROUND: Drought stress severely limits maize production in Northwest China. Although melatonin is known to enhance plant stress tolerance, its specific mechanisms in maize have not been fully elucidated. To address this, we investigated whether melatonin improves drought tolerance using two contrasting maize genotypes: drought–tolerant (SD–609) and drought–sensitive (SD–902). A experiment was conducted under...
