Phosphorus-solubilizing fungi improve growth and P nutrition in sorghum at variable salinity levels.

ABSTRACT:

Background

Salt-tolerant phosphorus solubilizing fungi (PSF) play a pivotal role in plant growth promotion and P-nutrition in saline agro-ecoregions. Isolation and characterization of salt-tolerant fungi with P-solubilizing potential and plant growth promotion of sorghum at different salinity levels were conducted.

Results

The best PSFs with inherent salt-tolerance were identified as Penicillium oxalicum (PO), Talaromyces islandicus 1 (Tal1), Talaromyces islandicus 2 (Tal2), Penicillium canescens (PC), and Penicillium setosum (PS). The PO demonstrated the highest salt-tolerance at 2% NaCl concentration. The P and Zn solubilization, ammonia, HCN, siderophore and IAA production were 1.1-10.5 times greater for the PO. The ascorbic and butyric acids were the most abundant organi
