Abstract: Vegetative propagation of Streblus asper an important medicinal plant, was studied for efficient rooting using different concentrations of auxins and  non auxinic Boric acid. Semi hard wood cuttings of   0.9 - 1.2 cm diameter from mature plants were collected and treated for 24 hours in liquid formulations of 50 ppm, 100 ppm and 200 ppm concentrations of IBA, IAA, NAA and 50 ppm, 150 ppm, 250 ppm and 350 ppm of  Boric acid individually and in combination. Results of the study revealed significant effect (p<0.05) of IBA and B combination on rooting and survival percentage and found that  50 ppm  and 10 ppm  IBA with 250 ppm of Boric acid induced highest  root number and length and significant  steckling capacity with high number of shoots than the other treatments and control. The study explores the scope of clonal propagation of S. asper by mature stem cuttings thus providing material for conservation of a selected clone.
