Abstract
The effects of growth regulators on culture response of different pyrethrum (Chrysanthemum cinerariaefolium Vis.) genotypes were investigated. In the genotype Sb/66/107, the presence of 2,4-dichorophenoxyacetic acid (2,4-D) at 2 mgl−1 promoted growth of callus, whereas benzyladenine and 1-naphthaleneacetic acid had no effect. Callus growth was also affected by the 2,4-D, ranging from 0.5 mgl−1 for genotype Marwanga to 3.0 mgl−1 for Ks/75/336. Among the genotypes, shoots were regenerated from calluses of Sb/66/107, 4331, Marwanga, and MA/70/1013.
