Salinity reduced root dry matter significantly and reduction was 68%
in salt sensitive cultivar and 26% in salt tolerant cultivar at 80 mM NaCl
compared to the control treatment (Table 1). Application of K2SO4 to saline
growth medium improved root dry matter in salt sensitive cultivar by 216%
at 2.5 mM K and 222% at 5 mM K compared with the salt treated plants
without addition of K. In salt tolerant cultivar, added K2SO4 also improved
