An unfamiliar class of electrical events with rapid rise and slow decay has been identified in tomato (Lycopersicon esculentum Mill.) plants impaled by metal electrodes. Rise-times of these extracellularly detected events can be 200 µs or less, while fall-times can require hundreds of milliseconds. In excised tomato shoots, these events are associated with the imposition of water stress. The hypothesized origin of these events is the fracture of water columns in the xylem and the triboelectrification that occurs as the ends of the columns snap apart.

Respiration in the light, dark respiration, and leaf water status were monitored once a day in leaves of woody plants as seedlings dried during 7- to 10-day periods. Light respiration was estimated from an electrical analogue model of the response of net photosynthesis to ambient CO2 concentration and also by the rate of CO2 evolution into CO2-free air. Respiration in the light was found to increase with water stress in four dry-habitat species and to decrease with stress in four wet-habitat species. Dark respiration changes could not account for the different trends observed. When light respiration in dry-habitat plants under water stress was temporarily inhibited, net photosynthesis during recovery from water stress was reduced compared with controls for at least a week. This may indicate a protective role of light respiration in these plants when under water stress.
