摘要：

Growth and survival of 10 strains of Rhizobium meliloti Dang. from Pakistan and Nepal were evaluated for their survival under drought in vials filled with sterile soil maintained at -0.03, -1.0 and -1.5 MPa. Rhizobia in the soil-filled vials were enumerated at 0, 4, 8, 14, 21 and 28 days after inoculation. The highest numbers of rhizobia per g of soil were observed at -0.03 MPa followed by soil maintained at -1.0 and -1.5 MPa. Strains UL 136 and UL 222 survived the best under drought and should be considered for commercial inoculant production in Pakistan. (C) 1997 Academic Press Limited.
