Abstract:
Callus cells of 'Shamouti' (Citrus sinensis Osb.) capable of growing in the presence of 0.2 M NaCl were obtained by exposure of the cultured cells to a medium containing salt. The growth curve of the selected salt-tolerant line (R-10) in the presence of NaCl showed a prolonged lag period, slightly slower rate of increase in fresh weight and about 50% yield as compared with the situation in the absence of salt. However, non-selected cells (L-5) did not grow in the presence of 0.2 M NaCl. The increased tolerance for salt of the R-10 cell line was retained after four consecutive transfers in medium without salt. This stability indicates that during the selection procedure a true genetic variant was isolated. R-10 cells selected for tolerance towards NaCl were also tolerant to other sodium salts. © 1982.
