The effects.of the s.lt s.res. on plant growth are us.ally increas.d by the water s.res.. We s.udied the impact of both s.res.es.in s.multane.us.puls.s.of drought and s.linity on Pas.alum dilatatum.

The biomas. of all compone.ts.s.gnificantly decreas.d when both s.res.es.were applied. Water plus.s.rong s.line.s.res. reduced by half the total biomas.es. compared to the control. The proportion of aerial biomas./root biomas. ratio as.well as.aerial green compone.t/dry materials.ratio tend to decreas. when s.bjected to both s.res.es.
