The effect of culture temperature on the morphogenetic response of Arachis hypogaea was studied. Cotyledons were cultivated on MS medium supplemented with 110 pM 6-benzyladenine. Leaf explants were cultivated in the presence of the same growth regulator at 22 ~tM. Cuhures were incubated at temperatures of 25, 28, and 35 + 5 ° C. Both direct organogenesis from cotyledons and development of organogenic calluses from leaves showed optimal rates at 35 + 5 ° C. The highest frequency of elongation of buds into shoots from leaf-derived calluses occurred in the presence of 5 ~M AgNO~. At the best culture temperature, an average of 95% of shoots formed roots on growth-regulator-free MS medium. Plants were successfully transferred to soil, showing normal phenotypes.
