Description: The effects of mechanical wounding on laticifer differentiation in Hevea brasiliensis were investigated by using the young stems in epicormic shoots.Light wounding by scraping to break the epidermal cells of young stem,usually caused the formation of a line of secondary laticifers in the area roughly equal to that of the wound.More lalicifers formed in a larger area in response to heavier wounding,such as that caused by deep scraping to remove part of cortex tissues of young stem or by cutting its bark into xylem.The first laticifers induced by scraping and cutting were visible as early as 6 days after wounding.The induction of laticifer differentiation by wounding in young stem was enhanced by the application ofjasmonic acid and linolenic acid,whereas induction was hindered to different degrees by the application of diethyldilhiocarbamic acid and nordihydroguaiaretic acid,which are inhibitors of jasmonate biosynthesis.Together with other evidence,these observations indicate that laticifer differentiation upon wounding is mediated by jasmonates.The involvement of jasmonates in wound morphogenesis is discussed.
