“…Also it is reported that inoculated seeds with PGPR showed high antioxidant enzyme activities against water and salt stress (Wang et al 2012). Heidari and Golpayegani (2012) reported that PGPR application increased the proline, chlorophyll and water content of basil (Ociumum basilicum L.) under water stress conditions. Proline has a function of osmotic adjustment in plants, but it also protects enzymes and membranes against oxidative stress (Agarwal & Pandey 2004).…”

“…Proline has a function of osmotic adjustment in plants, but it also protects enzymes and membranes against oxidative stress (Agarwal & Pandey 2004). A higher level of proline was observed in PGPR-treated plants subjected to drought stress (Heidari & Golpayegani 2012). El-Zieny et al (2001) indicated that the application of bio fertilizers such as Azotobacter improves leaf area and plant growth.…”

In order to study antioxidant status and physiological responses of wheat to cycocel (CCC) and bio fertilizers application under water limitation condition, a factorial experiment was conducted based on randomized complete block design with three replications in 2015. Treatments included water limitation in three levels [normal irrigation (I 1 ) as control; moderate water limitation (I 2 ) or irrigation withholding at 50% of heading stage; severe water limitation (I 3 ) or irrigation withholding at 50% of booting stage]; four bio fertilizer levels [(no bio fertilizer (F 0 ), seed inoculation by Azotobacter chrocoocum strain 5 (F 1 ), Pseudomonas putida strain 186 (F 2 ), Azotobacter + Pseudomonas (F 3 ))] and four CCC levels [(without CCC as control (C 0 ), application of 400 (C 1 ), 800 (C 2 ) and 1200 (C 3 ) mg/l)]. The results showed that water limitation decreased the chlorophyll-a, chlorophyll-b, total chlorophyll, carotenoid, stomata conductance, leaf area index (LAI) and relative water content of wheat, but activity of catalase (CAT), peroxidase (POD), polyphenol oxidase (PPO) enzymes and proline content were increased. Similar results were observed in CAT, POD and PPO activities due to bio fertilizers and CCC application. Besides the water limitation effects, CCC-treated plants displayed a significant decrease in stomata conductance and LAI. Generally, it was concluded that the application of bio fertilizers and CCC can be a proper tool for increasing wheat yield under water limitation. ARTICLE HISTORY

“…In strawberry plants regulated deficit irrigation technique is generally associated with reduction in fruit size and yield; (Liu et al, 2007). Despite this fact, other attributes, related to fruit quality increased (Terry et al, 2007;Heiadari, Golpayegani, 2012).…”

This study was conducted during 2011 and 2012 to evaluate the effect of 1-aminocyclopropane-1-carboxylate (ACC) deaminase-containing, N 2 -fixing and P-solubilizing bacteria on the yield and morpho-physiological parameters of strawberry. A total of 8 applications at the trial set, with four water regimes were randomly distributed into the pots. The diminishing water supply caused a gradual decrease in the plant growth,

“…Not many studies have focused on the effect of PGPR on the accumulation of antioxidants and pigments, while most of those that have been reported looked at the use of PGPR strains to alleviate the effect of abiotic stress. Heidari and Golpayegani (2012) demonstrated that the application of rhizobacteria improved the antioxidant and photosynthetic pigments of basil plants under water stress and Han and Lee (2005) showed that PGPR increased the chlorophyll content and decreased enzyme activity in plants under salinity stress.…”

Inherent Quality and Safety of Watercress Grown in a Floating System Using <i>Bacillus subtilis</i>

The aim of this work was to study the effect of substrate disinfection and application of plant growthpromoting rhizobacteria (Bacillus subtilis) on the yield, quality and safety of watercress grown in a floating system. Substrate disinfection had a positive effect on plant development because it increased the shoot antioxidant capacity and general plant growth and decreased the colony-forming units of molds. In turn, inoculation with B. subtilis increased the antioxidant capacity but decreased the chlorophyll a, chlorophyll b, and carotenoid contents and did not affect the rest of the parameters measured. In conclusion, our results showed that the effects of substrate disinfection were more pronounced than those obtained by B. subtilis inoculation, suggesting that it would be more convenient to reserve the use of plant growth-promoting rhizobacteria for other conditions, such as abiotic stress.
