Oxidative Stress and Senescence in Oat Leaves
Senescence is always associated with determinate growth and leaves can not escape from this behavior. In some cases determinate growth in plants seems result from genetic determination but in other cases it is a consequence of the environmental control (Trippi and Brulfert, 1973 a, b). However, people through years looked for an internal factor responsible for senescence. This communication deals with the effect of O2 concentration on senescence in detached oat first-leaves.
