title: Effects of element complexes containing Fe, Zn and Mn on artificial morel's biological characteristics and soil bacterial community structures.
abstract: This study described the effects of elements (including Fe, Zn, Mn and their complexes) on the following factors in artificial morel cultivation: the characteristics of mycelia and sclerotia, soil bacterial community structures, yields and contents of microelements. The results indicated that the groups containing Mn significantly promoted mycelia growth rates, and all the experimental groups resulted in higher yields than the control (P<0.01), although their mycelia and sclerotia did not show obvious differences. It was also found that Proteobacteria, Chloroflexi, Bacteroides, Firmicutes, Actinobacteria, Acidobacteria and Nitrospirae were the dominated bacterial phyla. The Zn·Fe group had an unexpectedly high proportion (75.49%) of Proteobacteria during the primordial differentiation stage, while Pseudomonas also occupied a high proportion (5.52%) in this group. These results suggested that different trace elements clearly affected morel yields and soil bacterial community structures, particularly due to the high proportions of Pseudomonas during the primordial differentiation stage.
