Gas exchange characteristics and water relations in two cultivars of Hibiscus esculentus under waterlogging
Year: 2005
Type: article
Abstract: Thirty-day-old plants of two okra cultivars, Sabzpari and Chinese-red, were subjected for 30 d to normal watering or continuous flooding. Continuous flooding did not cause any adverse effect on shoot fresh and dry biomass. Leaf water potential and pressure potential of both cultivars increased significantly due to waterlogging, but there was a slight increase in leaf osmotic potential. Chlorophyll a and b contents decreased significantly and chlorophyll a/b ratio increased. Waterlogging caused a significant reduction in net photosynthetic rate, water use efficiency and intrinsic water use efficiency, but stomatal conductance and intercellular CO2/ambient CO2 ratio remained unchanged.
