Analysis of Leaf and Soil Nutrients, Microorganisms and Metabolome in the Growth Period of <i>Idesia polycarpa</i> Maxim

Abstract

Idesia polycarpa Maxim is an emerging oil plant species. Understanding its microecological characteristics and internal mechanisms can serve as a basis for field management and the screening and application of growth-promoting bacteria during the growth phase of young trees. This study used three-year-old young I. polycarpa to analyze the tree’s root morphology, soil, and leaf nutrient status variations from May to October. In addition, differences in the rhizosphere soil, leaf metabolites, and microorganisms were observed. The results showed that, from May to October, the total nitrogen (TN) in the soil significantly decreased, whereas the TN, total potassium (TK), and total phosphorus (TP) in the leaves differed (p p p Pedomicrobium sp., Talaromyces sp., Penicillium sp., and D-Mannitol 2.
