KATHIRESAN, K y RAJENDRAN, N. Growth of a mangrove (Rhizophora apiculata) seedlings as influenced by GA3 , light and salinity. Rev. biol. trop [online]. 2002, vol.50, n.2, pp.525-530. ISSN 0034-7744.
The growth performance of Rhizophora apiculata Blume (mangrove) seedlings in the presence and absence of exogenous gibberellic acid (GA3 ) under different combinations of salinity and light was analyzed. Root and shoot growth responses of 75-day old seedlings in liquid-culture, were measured. It was concluded that light exhibited a significant inhibitory effect on all the growth parameters-number of primary roots, primary root length, shoot elongation, number of leaves, total leaf area; and, the GA3 treatment singly or in combinations with light, showed a significant influence on the total leaf area and primary root length
