Effects of water stress and partial soil-drying on senescence of sunflower plants

Wongareonwanakij, Sathaporn. January 1995 (has links) (PDF)
Bibliography: leaves 98-123. This thesis investigates the symptoms of leaf senescence in response to plant shoot water stress and demonstrates the effect of a non-hydraulic root signal in the senescence response of mature leaves of sunflower. The alleviation of the leaf soluble protein loss rate by excision of the root system in drying soil indicates that this signal originates in roots in dry soil and acts to promote protein loss.
