Abstract
Plants of peanut (Arachis hypogaea L.) were subjected to 7-d and 14-d waterlogging and sprayed with 10 and 100 mg 1-1 of gibberellic acid (GA3). Waterlogging decreased the leaf area (A), net photosynthetic rate (Pn), chlorophyll content (Chi) and temporarily the leaf water potential (Ψw) and increased stomatal diffusive resistance (rs) of both leaf surfaces. Application of GA3 increased A and Pn and significantly decreased the rs of both leaf surfaces but did not affect Ψw or Chl. Thus GA3 partially alleviated the effects of waterlogging on A, rs and Pn.
