Pant Prabhat raised in vitro and ex vitro. Treatment of 0.1% HgCI2 for 10 minutes on ex vitro grown seedling was recorded maximum survival of explant after 5 days of inoculation. Maximum callus induction in shortest time (33.43%) from in vitro grown seedlings and ex vitro grown seedlinR (28.42%) were observed in MS media containing NAA (1 mg 1-1 + 2,4-D (2 mg 1- ) + Kinetin (1 mg 1-1. Hypocotyl explant induced maximum callus in both types of explant irrespective of hormonal combinations.  aCultura de Tecido  aGoiaba  aPsidium Guajava  aRegulador de Crescimento1 aTIWARI, J.
