Oxidative stress, leaf photosynthetic capacity and dry matter content in young mangrove plant Rhizophora mucronata Lam. under prolonged submergence and soil water stress.

ABSTRACT: Young plants of Rhizophora mucronata Lam. were tested for oxidative stress, photosynthetic capacity and dry matter accumulation under two abiotic stress conditions; prolonged submergence and soil water stress. The experiment of prolonged submergence was performed in field conditions with two treatment levels; 50% inundation (control) and 100% inundation levels. The experiment of soil water stress was conducted in a plant-house with four treatment levels, 100% water holding capacity (WHC) (control), 50% WHC, 25% WHC and high salinity (> 35 psu). The experimentation period was 18 months. According to the results, antioxidant activity was increased in the 100% inundation level in field conditions and in the 25% WHC, 50% WHC and high salinity levels in plant-house conditions. However, d
