Abstract
Arbuscular Mycorrhizal fungal (AMF) is one of the important microbiota, which are involved in reciprocal relationship with more than 70% of plants. Till date, there are 255 AMF spores species which have been discovered with various functions. AMF colonization and spore density is depend on the AMF spore type and plant species as well the environmental circumstances. Some of the highlighted spore functions have recently been thoroughly researched. Nevertheless, the impact of some AMF spores on maize and clover growth and metabolomics have not been investigated. In order to explore the function of specific AMF spores on maize and clover, an experiment was conducted in Northwest A&F University, China. Four types of AMF spores i.e. Glomus etunicatum (Ge), Glomus Intraradices (GI), Glomus mosseae (Gm), Acaulospora denticulate (Ade) were applied on clover and maize. The result showed that Ge and Ade have significant effect on clover and maize growth. Both Ge and Ade increased clover and maize plant height by 21% , 18%, 26% and 19% respectively, also Ge and Ade enhanced the root length of clover and maize by 26%, 21%, 45% and 36% respectively. Furthermore, Ge and Ade significantly increased the chlorophyll content in both clover and maize. Besides, the metabolomics activities were found at higher under Ge followed by Ade addition in both plants. Soils inoculated with Ge and Ade had the greatest AMF colonization in clover and maize root. The results showed that all four AMF spores have a beneficial effect on clover and maize, although the Ge and Ade followed by Gi have a greater impact, which indicates that Ge and Ade could increase the plant growth of maize and clover by improving chlorophyll content and affecting metabolomics activities.
