Abstract

In this work, effects of PGPR, some natural plant extracts and certain antioxidants on incidence of root rot diseases and defensive enzymes of tomato under greenhouse conditions were studied. Results showed that disease severity of tomato in soil infected with F. solani and R. solani were reduced in S1 and S2in the soil incubated with PGPR compared with the soil not incubated
Total phenolic compounds (TPCs) levels in untreated samples are always lower than those reported in treated ones.
The sane trend was also recorded in the case of TFs. Chlorophylls concentration fluctuated as a result of infection and treatments. Effectiveness of studied plant extracts could be arranged in the following order: WE> OBE> MOE> CCE.
Three different defensive enzymes i.e. catalase, peroxidase and polyphenol oxidase showed that the treatments led to decreases in the levels of PPO activities compared with the untreated sample except propylgallate (PG).
The five organic substances have effective antioxidant and could be arranging it in the following order: PG > Na-Tannate >L-AA > SA >Na-Benzaoate. All these five substance are phenolic compounds and have antioxidant potentials
