Factors Influencing Adventitious Root Production in Cuttings of Griselinia littoralis and Griselinia lucida

Griselinia littoralis roots quickly and vigorously from cuttingsof seedlings and mature plants and also forms roots on detachedleaves. Cuttings root in the dark but leaves must be present.In contrast G. lucida roots vigorously only from cuttings takenfrom seedlings. Light is essential for root formation on oldermaterial. Detached leaves will not root. Although callus formationat the cut base commonly occurs in both species it is not directlyassociated with root formation.
