ROLE OF DIFFERENT REVIVE ROOTING HORMONES FOR EX-VITRO ROOTING OF ADHATODA VASICA NEES. & BARLERIA PRIONITIS L.

Abstract

The plants propagated by seeds are highly heterozygous thus; variations in genetic characters are to be expected. In vegetative propagation, unlike generative method, superior traits or characters of mother plants with respect to yield oil quality and disease resistance are conserved in their progenies, hence the study was undertaken. Effect of the different growth regulators (revive rooting hormones-Rootex) (Rootex-a, b, c; Natural Agrotech Indore.) on rooting of halfwoody shoots of Adathoda vasica Nees. and Barleria prionitis L.  were studied. Without stimulation, rooting in these medicinal plants occurred but after 7 weeks and after stimulation rhizogenesis takes 2 to 3 weeks. Growth regulators, with the exception of the preparation Rootexc, showed a significantly stimulating effect on rhizogenesis, and effect of them declined in the order Rootex-a, Rootex-b and Rootex-c. The percentage of rooting in these medicinal plants Adathoda vasica Nees and Barleria prionitis L.  was higher in preparations of 30gm/50 ml DW(Distilled Water) than that in other preparations in both cases of Rootex-a and Rootex-b. Poor rooting was found in the case of Rootex-c in all types of preparations. Rhizogenesis also varies according to the age of the plants, cutting, substrate, and conditions of cultivation.
