The effect of Na2SO4 salinity (sand culture) on root length, shoot length, total length (Height of Plant), root / shoot ratio, biomass (fresh and dry wt.) and chlorophylls, polyphenols and proline contents of a sodium loving plant Trianthema portulacastrum L. has been investigated. The plants were raised from seeds in acid free silica sand culture with Hoagland nutrient medium and treated with 0.0 (control), 100, 200 and 300mM Na2SO4 for two months. The plants exhibited better performance in growth and development under low salinity (100mM Na2SO4) level, 300mM salt concentration was slightly harmful. Amount of total chlorophylls, chl. at and chl. b, was significantly reduced under increasing salinity levels. Polyphenol level was increased with increasing salt level in the medium. Proline content was also significantly increased under increasing Na2SO4 salinity level. Trianthema portulacastrum L. appears to be moderately tolerant to Na2SO4 salinit.
