摘要：

Woody cuttings from three ungrafted rootstocks, with decreasing resistance to lime-induced chlorosis (V. berlandieri x V. rupestris 140 Ru; V. berlandieri x V. riparia SO 4; V. riparia x V. rupestris 101-14), were potted in unsterile calcareous soil with Pseudomonas fluorescens cells and Glomus mosseae inoculum to test the effects of these organisms on some physiological parameters involved in chlorosis occurrence. The most significant findings are: (i) P. fluorescens and G. mosseae treatments increase ferrous iron and chlorophyll leaf content in the rootstock more susceptible to lime-induced chlorosis (101-14); (ii) increased mycorrhizal colonization, over the control, enhances N, P, Mn and Cu concentration in leaf fresh matter.
