Abstract
Abstract A pot experiment was conducted to evaluate the response to vesicular‐arbuscular mycorrhizal (VAM) infection of two species of Cassia and Gliricidia sepium in an oxisol with two levels of soil P. At P level optimum for VAM activity, comparable levels of VAM infection were observed on the roots of the test species. However, the species reacted differently to VAM infection. Hence, VAM inoculation significantly stimulated dry matter accumulation in C. spectabilis and G. sepium, but had no positive influence on this variable in C. reticulata. These differences were not explainable in terms of tissue P status, because P uptake was significantly enhanced by inoculation in all the species tested. At the higher soil P level, roots of all species were colonized by the inoculum, but colonization level in C. reticulata and G. sepium was reduced. Nevertheless, only C. spectabilis benefitted from the presence VAM endophytes at this level of soil P. The results underline the significance of ascertaining the mycorrhizal requirements of host species before reliable VAM inoculation recommendation could be made.
