Summary, etc Hevea brasiliensis Muell, Arg is major source of natural rubber and is propageted vegetatively by budgrafting throughout the rubber producing countries. But stock-scion interactions existing in the budgrafting plants results in considerable intraclonal variability in growth and yield. Rootstocks could be avoided by air-layering and thus obtain homogeneous plants, but there was a wide variation in the rooting response of different clones (0-95;). Two auxins, viz, IBA and NAA at five concentrations, viz 0, 100, 250, 500 and 1000 ppm and Rootex ( a commercial formulation of IBA in powder form) were tried to evaluate the effects of these hormones or rooting in air-layers of three promising clones of Hevea brasiliensis. There was an appriciable increase in the percent of rooting as well as mean number of roots per layer with the application of these hormones. Percent of rooting and mean number of roots per layer were dependent on the concentration was different in different clones studied. 250 ppm IBA was found to be optimum for two clones, RRIM 600 and GT1, which were somewhat medium rooting. But a higher concentration of 500 ppm IBA was needed for optimum for rooting in a hard-to-root clone like RRII 105. Irrespective of the clones studied, a very high concentration of 1000 ppm IBA or NAA was inhibitory to rooting.
