Salinity effect on potato (Solanum tuberosum L.) micropropagation

Abstract

The effect of salinity on plantlets growth was determined under saline medium and non-saline at five cultivars of potato (Christian, Roclas, Marfona, Riviera, Tresor). Plantlets belonging to selected cultivars, were propagated through single nodal culture. To study the effect of salinity (NaCl) on the growth of single nodal explants, they were cultured on MS media with different concentrations of NaCl, including 0, 25, 50, 75 and 100 m mol l-1. Growth of single nodal explants on the media with NaCl indicated that all the characters differed significantly according to salinity levels. By increasing salinity level the values for all the parameters decreased.
