	MICROPROPAGATION AND CALLOGENESIS OF A RECALCITRANT SPECIES RICINUS COMMUNIS SHAGUFTA NAZ^1, FOZIA TABASSUM, SUMERA JAVAD¹, SAIQA ILYAS^1, FARAH ASLAM¹ NEELMA MUNIR¹AND AAMIR ALI² Abstract:* The present study deals with the micrpropagation and callogenesis of Ricinus communis, a medicinally important but recalcitrant plant species. Different media were evaluated for the micropropagation and callus induction from different explants of the plant. The best response was obtained on MS medium supplemented with 18µm TDZ, where percentage of multiple shoot formation was 90%. The callus induction from cotyledonary leaves were tested using different media, the best response (90%) was obtained on MS medium supplemented with 2.5mg/l BAP + 0.5mg/l NAA where whitish brown friable callus with maximum proliferation was produced. ¹Department of Biotechnology& Microbiology, Lahore College for Women University, Lahore, Pakistan²Department of Biological Sciences, University of Sargodha, Sargodha, Pakistan^*Corresponding author E-mail: drsnaz31@hotmail.com
