The Synergistic Effect for Pseudomonas Fluorescens and Salicylic Acid in Chlorophyll A, B and Carotene Content of Wheat Plant (Triticum Aestivum L.)
Main Article Content
Abstract
The aim to study the effect of salicylic acid at level (50-100 and150 ppm) and pseudomonas fluorescens at (105-106-107 c.f.u./ml )on chlorophyll a, b and carotene for two varieties (Abu-graib ,Abaa 99)of Triticum aestivum L. The results indicates the significant effect of pseudomonas fluorescens and salicylic acid at the combination concentration P. fluorescens (106c.f.u./ml) (FP2) + SA concentration of (100 ppm) (SA2) ) for variety (Abu-graib) was more impact than (Abaa 99) on the physiological aspect like chlorophyll a, b , and carotene content (2.832 , 0.963 , 0.969) mg/g fresh weight respectively while the value of control was (2.113, 0.612, 0.618)mg/g respectively. on other hand the results showed that the use of salicylic acid and pseudomonas fluorescens induced better as compared with the sole application of SA or pseudomonas fluorescens.
