A study on the standardisation of pre-sowing hardening techniques in Acacia nilotica indicated that soaking of acid scarified seeds in water for 90 hrs. followed by 3 hrs. of shade drying was optimum for seed hardening. Hardened seeds performed better recording higher germination and vigour under a low WHC of 30% than under a high WHC of 50%.
