Fig. 4From: Effect of plant growth-promoting rhizobacterial treatment on growth and physiological characteristics of Triticum aestivum L. under salt stressA Germination percentage and B germination rate index of T. aestivum seedlings upon treatment with various rhizobacterial inoculants under salt stress. Control had no bacterial treatment. M1, co-cultures of PN89 + PnIHB; M2, co-cultures of PnIHB + PP7S; M3, co-culturing of PP7S + PN89; Mix, co-cultures of PN89 + PnIHB + PP7S. Error bars represent standard deviation (n = 3). Different superscripted letters for each NaCl concentration indicate significant difference among various bacterial cultures according to Duncan's test (p = 0.05)Back to article page
