摘要

This study examined the potential of stress-tolerant phosphate-solubilizing bacteria (PSB) to enhance drought and salinity tolerance of Vicia faba (Faba bean) and Pisum sativum (Pea). The assessment focused on soil parameters, morphological, physiological, and biochemical responses of the host plants, to clarify the mechanisms underlying PSB-mediated stress reduction under extreme conditions. After screening, DNA sequence analysis of 16 S rRNA genes of five isolates revealed that they belong to Pseudomonas spp and Bacillus spp. The five PSB isolates that exhibit plant growth-promoting properties were used as a consortium in three different treatments BC1 (3 isolates), BC2 (3 isolates), and BC3 (5 isolates). The results show that, under drought and salt stress conditions, grain number per plant increased in BC3 inoculated seeds, followed by BC1 for both tested crops, compared to untreated plants. Moreover, BC3 is the best performing, showing the highest seed protein content (83.22% -156.57% for Faba Bean seeds and 53.3% − 172.64% for Pea) under all conditions compared to the control. The highest level of alkaline phosphatase activity (APA) was also determined in BC3 treatment with 22.23 µg pNP g− 1, and 22.62 µg pNP g− 1 for faba bean and pea, respectively, as compared to the control. Grain phosphorus content in BC3 treatment compared to the non-inoculated increased from 139.32% to 455.71% for Faba Bean seeds and from 91.32% to 490.44% for Pea seeds, respectively. These findings demonstrate how PSB strains may be used in sustainable agriculture, providing a viable way to raise crop yields in saline or arid soil.
