Abstract:
An Fe efficient (Arachis hypogaea L. cv. 71–234) and an Fe inefficient (cv. Tainan 9) peanut cultivar were subjected to four inoculation treatments (NH4NO3 without inoculation, NC 92, TAL 1000 and a mixture of these two Bradvrhizobiurn sp. (Arachis) strains with THA 205) and grown under Fe stress conditions in complete nutrient solution including 0.2 mM NH4NO3 and 0.012 mM FeEDDHA at pH 8. 6 maintained by addition of 5 mM NaHCO3 and solid CaCO3. During the first four weeks, cv. 71–234 grew better than cv. Tainan 9 in all inoculation treatments but by eight weeks these differences had largely disappeared. By contrast, inoculation treatments had no effects on shoot and root dry matter at four weeks but large effects at eight weeks when plants inoculated with NC 92 alone or in a mixture had similar or more. © 1988, Taylor & Francis Group, LLC.
