Iron Chlorin E6 enhances drought resilience in <i>Camellia oleifera</i> Abel.

ABSTRACT: This study investigates the effects of Iron Chlorin E6 (ICE6) on the physiological and biochemical responses of Camellia oleifera plants under both normal and drought stress conditions. Varying concentrations of ICE6 (0 µg/L, 20 µg/L, 40 µg/L and 80 µg/L) were applied to C. oleifera plants to assess physiological parameters, including photosynthetic rate, chlorophyll content (SPAD, Soil Plant Analysis Development chlorophyll meter), antioxidant enzyme activity, proline content (Pro), soluble sugars (SS), soluble proteins (SP), abscisic acid (ABA) levels and gene expression. Under well-watered conditions, 80 µg/L ICE6 significantly enhanced net photosynthetic rate (Pn) and SPAD values by 113.73% and 11.57%, respectively, compared to the control, while promoting indole-3-acetic
