Abstract
Abstract On current season’s growth of sour cherry (Prunus cerasus, cv. Montmorency) injury induced by (2-chloroethyl)phosphonic acid (ethephon) occurred at and below the nodes in tissues adjacent to the 3 leaf traces supplying each leaf. In the secondary xylem close to the cambium, separation and breakdown of cell walls resulted in the formation of gum cavities; injury occurred also in cortical tissues adjacent to the leaf traces. In older portions of the branch more severe injury occurred where large gum cavities formed in the outer secondary xylem and in cortical tissues. Superficial swelling, cell proliferation and surface cracks occurred on the branches near the nodes accompanied by exudations of gum. Injury and cell wall dissolution may be related to cellulase activity stimulated by ethylene released from the break down of ethephon within the tissues.
