Viviparous hypocotyls of Rhizophora mucronata were treated with ascorbic acid, KCl, KMNO4 and MgCl2 for 24, 48 and 72 hours at different concentrations. The chemicals enhanced initiation and elongation of roots. There was a maximum increase of 62% in number of primary roots, 255% in number of secondary roots in the seedlings treated with ascorbic acid and MgCL2 respectively. Also, a maximum increase of 85% in average root length and 48% in maximum root length were recorded with KMNO4 treatment. Hence, the chemicals have been suggested for efficient rooting of Rhizophora seedlings.
