Abstract
Abstract The effects of vesicular‐arbuscular mycorrhizas (VAM) on the growth of Zea mays L. cv.s ‘PX610’ and ‘W415’, and Z. mays × robusta cv. ‘Yates Golden Cross Bantam’ (sweetcorn) were compared. Among the three cultivars there were highly significant differences in responsiveness to VAM as well as in root dry weight/total dry weight ratios, lamina P concentrations, and growth rate. In the absence of P, PX610 outgrew the other two cultivars and was well infected, but it failed to respond to VAM. In the non‐mycorrhizal state the superiority of PX610 over the other cultivars was attributed to its superior ability to produce roots and its low lamina P concentrations. VAM depressed the root dry weight/total dry weight ratio of PX610 but not of sweetcorn or W415.
