Abstract
Abstract One-month-old seedlings of 20 entries of tomato ( Lycopersicon esculentum Mill.) were subjected to flooding for 3 days, or drenched with ethanol or (2-chloroethyl)phosphonic acid (ethephon) solution. Flooding reduced stem growth and leaf chlorophyll content of thelower leaves and promoted epinastic curvature of leaf petiole and adventitious roots. Application of ethephon elicited a response similar to that of flooding. No prominent morphological and physiological changes were observed from ethanol application. Flooded plants show increases in their endogenous free proline pool, which can be reduced by the withdrawal of flooding. Flooded L-123 plants, the most tolerant entry, accumulated the least free proline among three entries tested. Proline level appeared to indicate the intensity of oxygen deficiency during soil flooding by reflecting oxygen supply, and could serve as in indicator in relating plant injury to flooded conditions. The tolerance of L-123 to soil flooding, at least in part, depends on its ability to transport oxygen from the aerial part to the root.
