Factors affecting the rooting response of plants to growth regulator application


, : Factors affecting the rooting response of plants to growth regulator application. Acta Horticulturae (34): 93-105

Factors which influence the response of cuttings to treatment with root-promoting auxins are reviewed, with particular reference to the efficient entry of auxin into hardwood cuttings.
