Abstract<\/strong><\/p>\n

This research was conducted to study the effect of four bacterial strains (PGPR): Pseudomonas chlororaphis<\/em> MA342, Serratia<\/em> plymuthica HRO-C48, Bacillussubtillis<\/em> B2g and B<\/em>. subtillis<\/em> FZB27 to improve the growth of tomato plants in the greenhouse. Bacterial strains were applied to the seeds in a concentration of (1010<\/sup> cfu\/ml), of each bacterial strain. The results showed the treatment with bacteria improved peroxidase enzyme activity at a rate of (2.15-6.35) % after 78 days of treatment compared with non-treated control (0.002) n mol, and a rate of (60.71- 232.14) % after 94 days compared with non-treated control (0.056) n mol. The treatment with bacteria increased the height of plant at a rate of (1-21.37)% compared with non-treated control (57.83) cm, and increased fresh weight of foliage at a rate of (9.25-122.56)% compared with non-treated control (317)g, while it increased dry weight of foliage at a rate of (3.89- 61.98)% compared with non-treated control (111.33)g, and increased fresh root weight at a rate of (22.39-310.48)% compared with non-treated control (22.33)g, and increased root dry weight at a rate of (9.09- 33.27)% compared with non-treated control (5.5)g, and increased number of fruits at a rate of (7.73-54.73)% compared with non-treated control (8.66 fruit), and increased weight of fruits at a rate of (5.69-60.33)% compared with non-treated control (105.33)g . The strain B27 had the highest values of the studied traits.<\/p>\n
