Abstract

Salt and pH tolerance ofRhizobium strains specific forSesbania cannabina Pers., sannhemp (Crotalaria juncea L.) and soybean [Glycine max (L) Merr.] have been studied. The salt effect appeared to be ion-specific. Chlorides were more toxic than sulphates of Na, K and Mg. MgSo4 has a stimulatory effect at lower than 1.0%. 0.2–0.8% NaHCO3 was lethal for all the strains.S. cannabina was most salt (3.0%) and alkali (pH 10.0) resistant. Both salt-resistant and salt-sensitive strains were present in the case of sannhemp and soybean. pH 10.0 was not inhibitory for any strain but the strains were sensitive to acidity (pH 3.5–4.0).
