The plasticity differences of tumourous and non tumourous Nicotiana genotypes were studied on the growth response in vitro of primary explants of pith tissue extracted from plants of different age and submitted to different hormone treatments. The data obtained confirmed important differences in the homeostatic ability of the three analysed genotypes, the non tumourous stock being clearly more stable than the others. The lack of response of the non tumourous genotype is discussed in relation with other known differences between the tumourous and non tumourous type.
