SALINITY INDUCED CHANGES IN SOME GROWTH AND PHYSICO-CHEMICAL ASPECTS OF TWO SOYBEAN [GLYCINE MAX (L.) MERR.] GENOTYPES ALI KAMAL, M. SALEEM QURESHI, M. YASIN ASHRAF AND M. HUSSAIN Abstract: Effect of salt stress on plant biomass production
and some biochemical parameters of two soybean [Glycine max (L.)
Merr.] genotypes were investigated under three NaCl salinity levels
(control and 3.0, 4.5 and 6.5 dsm-1). Salinity induced a
marked reduction in plant height and plant biomass production in both
genotypes. Chlorophyll a, chlorophyll b and total chlorophyll increased
with increase in levels of salinity. A marked increase in sodium (Na+)
and chloride (Cl-) contents were observed in response to
salinity, whereas potassium (K+) and nitrogen contents of
salt stressed plants were lower than that of controls. Genotypes did
not differ significantly regarding all the parameters studied. Deptartment of Botany, University of Agriculture, Faisalabad, Pakistan. |
