High-temperature Disruption of Guard Cells of Vicia faba: EFFECT ON STOMATAL APERTURE 1
AUTOR(ES)
Rogers, Cynthia
RESUMO
Increased variability in stomatal aperture at high temperatures can be attributed, in part, to the differential sensitivity of guard cells to thermal damage. Individual stomata become increasingly open at higher temperatures until guard cells are lethally damaged; at that temperature, apertures decrease. The extent of irreversible damage causing closure was estimated by K+ uptake, neutral red accumulation, and visual scoring of chloroplasts.
