In viviparous hypocotyls ofRhizophora apiculata Blume the triacontanol treatment enhanced the growth of root and shoot (number of primary and secondary roots, length of roots, shoot height and biomass) protein and energy contents of leaves and roots,in vivo nitrate reductase activity, contents of chlorophylls and carotenoids in leaves as well as the amount of chlorophylls present in photosystems 1 and 2 and in the light harvesting complex of chloroplasts. These promotory effects were recorded at 40 and 80 mg m-3 triacontanol, but they decreased with increasing growth regulator concentration.
