Characteristics of NaCl-Tolerant Calli and Somaclones of Tomato
The genetic basis for NaCl tolerance in the tomato has been proved (Rush and Epstein 1976, 1981). Salt tolerance mechanisms are thought to be cell-based and do not depend on whole plant organization in Lycopersicon (Tal et al. 1978, Tal and Katz 1980, Taleinsk-Gertel et al. 1983). Different mechanisms for NaCl tolerance have been described: salt exclusion (Jia-Ping et al. 1981), osmotic regulation (Orton 1980) or organic synthesis (Rush and Epstein 1976). The objective of this work is to describe the characteristics of NaCl-tolerant morphogenetic calli and isolated somaclones of three tomato land races from the Canary Islands.
