ABSTRACT
Roselle (Hibiscus sabdariffa L.) is an important leafy vegetable in the country and used for medicinal and industrial purposes. Knowledge on physiological basis of salt tolerance in Hibiscus sabdariffa plant species is an essential pre-requisite not only for success of efforts aimed at selecting salt tolerant landraces, but also for perpetuation of their biodiversity as well as their sustainability. Effect of salinity stress using different concentrations (0.15%, 0.30% and 0.45%) of various salts (NaCl, Na2SO4, Na2CO3, NaCl+ Na2SO4, NaCl+ Na2CO3, Na2SO4+ Na2CO3, NaCl+ Na2SO4+ Na2CO3) was studied in three landraces (R.K.S.I, R.K.S.II and R.K.S.III) of Roselle (Hibiscus sabdariffa L.) at 30 and 90 days after sowing. Salinity stress effects on leaf area, stomatal index, stomatal frequency of the landraces were studied. Based on the present study, the roselle landrace R.K.S. I (Hibiscus sabdariffa L.) was found to be more salt tolerant than the other two landraces (R.K.S.II and R.K.S.III).
Key words: Salinity, Rosell, Leafarea, Stomatalindex, Stomatal frequency
