Effect of Cork Flour Supplementation on the Growth Indices and Rhizosphere Bacterial Communities of Quercus variabilis Seedlings

Substrate and rhizosphere microorganisms are key factors affecting seedling growth; however, the effects of substrates bacteria on growth Quercus variabilis not completely understood. Here, Q. seedlings were grown in with without cork flour, as follows: H substrate (charcoal soil/cork flour/perlite, 1:1:2), S (cork 1:1), control (CK) soil/perlite, 3:2). High-throughput sequencing qPCR used to investigate these growth, physiological indices, bacterial communities. Root shoot weights significantly higher than those CK. Moreover, was conducive chlorophyll synthesis leaves, transpiration rate intercellular CO2 concentration leaves The number 16S rRNA copies greater case for As well, richness Thus, cork-flour-supplemented beneficial development, abundance diversity, nitrogen phosphorus metabolism-promoting microbial taxa.
