Tomato accessions PI 128644  (Lycopersicon peruvianum  var.  dentatum  Mill.) and PI 406966  (Lycopersicon esculentum  Mill.) were identified in preliminary screening trials as being relatively nonresistant and resistant to 120 hr of flooding, respectively. Many adventitious roots (AR) developed on the lower stems of flooded PI 406966 seedlings, while few formed on flooded PI 128644 plants. Root formation by flooded PI 406966 seedlings depended on  de novo  initiation rather than emergence of preformed initials. Hypocotyl porosity of PI 406966 plants increased from between 3% and 6% to 8% by 36 and 72 hr of flooding, respectively. Porosity of PI 128644 hypocotyls was unchanged by 72 hr of inundation. Flooding did not affect the secondary root porosity of either accession. The limited capacity of PI 128644 seedlings to develop AR and aerenchyma was not related to an inability to synthesize 1-aminocyclopropane-l.carboxylic acid or ethylene in response to hypoxia. Chemical name used: 1-aminocyclopropane-1-carboxylic acid (ACC).
