The responses offour provenances of Acacia nilotica to salinity (0,75,150, and 225
mMNaCl) at the germination stagewere examined experimentally and compared with their
known salt tolerance at the seedling stage. There were significant differences in final
germination percentage and germination rate between salinity treatments and between
provenances. The provenance (Tunzini, Swaziland) which appeared more salt tolerant
during germinationwas notmost tolerant at the seedling stage.
