PGP potential of the microbial collection.

Percentage distribution of plant growth promoting activities and tolerance to abiotic stress among the isolates of the bacterial collection obtained from the different fractions of the pepper root system and the non-cultivated arid soil.
Auxin  =  auxin production; P Sol.  =  inorganic phosphate solubilization; EPS  =  exopolysaccharide release; Sid. = siderophores production; NH3  =  ammonia production; Prot.  =  protease activity; PEG = poly-ethylen-glycol.
