Plantlets were regenerated from a selected salt-tolerant cell line of Shamouti orange (Citrus sinensis L. Osbeck). Embryogenesis was carried out both in the presence and absence of NaCl, yielding green and white globular embryos, respectively. Greening could be induced subsequently and normal heart shape embryo development was obtained. Plantlet formation required exposure to kinetin prior to the introduction of the root-inducing hormone naphthalene acetic acid. This system differs from the designed protocol for plant regeneration from the salt-sensitive, i.e., unselected callus. It is concluded that NaCl interferes with the regeneration process, with embryogenesis and/or embryo development into plantlets. Its presence during callus growth probably changes the balance of the phytohormones which is later manifested in plant regeneration. Citrus salt-tolerant callus yields salt-tolerant embryos. Salt-tolerant calli derived from regenerated plantlets indicate acquisition of salt tolerance on the whole plant level. © 1989 Springer-Verlag.
