Hormonal Control of Senescence
Three approaches are currently used for the investigation of the hormonal control of senescence: 1) the assay of the effects on senescence of externally added growth regulators, 2) the measurement of hormonal concentration and/or sensitivity changes during senescence, and 3) the study of the mechanisms through which hormones affect some specific senescence sympton. Here, we mostly deal with the third approach in relation to the chloroplast breakdown symptom accompanying the senescence of the leaves of barley (Hordeum vulgare. L. cv. Hassan).
