Abstract
Rooting in stem cuttings of two species of Aconitum collected from alpine area of Tungnath (Garhwal Himalaya, 3600 m altitude) was studied at two altitudes (3600 & 2576 m). In A. balfourii rooting took place at both the altitudes, whereas in A. heterophyllum rooting did not take place at any of the altitudes even after auxin treatment. Low altitude favoured rooting and elongation of roots. The higher concentration of auxins were more effective in inducing the rooting in A. balfourii at higher altitude.
