“…The seed germination depends on the viability of the embryo and the breaking of dormancy generated by environmental conditions (Luna- Martínez et al, 2013). The PGPB can influence the latter case since the reduction in ethylene levels due to the ACC deaminase activity of bacteria in the seed increases germination, along with the production of IAA that stimulates cell division in order to promote the growth of the embryo (Glick et al, 2007;Jalili et al, 2009).…”

The capacity to solubilize phosphate and to produce indole compounds Indole Acetic Acid type, was evaluated in 15 strains isolated from castor bean lignocellulosic residues (Ricinus communis). To determine the solubilizing activity of phosphates a qualitative test by using Pikovskaya culture medium was employed and for the evaluation of the production of indole compounds (IAA) a Salkowsky colorimetric analysis technique was applied. Among the microorganisms tested, the Bacillus pumilus GIBI 206 demonstrated capacity to solubilize phosphates and Bacillus subtilis GIBI 200 showed of capacity to solubilize phosphates and to produce Indoleacetic Acid (IAA). To determine the effect of the Bacillus subtilis strain on germination and growth promotion, tomato seeds (Solanum lycopersicum 'Santa Clara') were inoculated; the inoculation of the seeds along with the microorganism revealed statistically significant differences, during the germination stage compared to the control treatment. Nevertheless, it revealed a positive influence on the development of tomato plants, originating a significant increase on the mass and length of its stem and root. The results of this research offer the possibility of using the Bacillus subtilis as a growth promoter in tomato seedlings and in the formulation of bio-products.

“…Salinity has been reported to affect many physiological processes such as seed germination, photosynthesis, respiration and metabolite accumulation, which negatively affects the growth and yield of legume plants by its inhibitory effect on biological nitrogen fixation, less supply of photosynthates to nodules (Bekki et al, 1987), reduced supply of respiratory substrates to bacteroids (Delgado et al, 1994) and modifications in the diffusion barrier of oxygen (Serraj et al, 1994). Moreover, during exposure of plants to salt stress conditions, enhanced synthesis of 1-aminocyclopropane-1-carboxylic acid (ACC) occurs (Jalill et al, 2009), which resulted in production of stress hormone ethylene (Arshad and Frankenberger, 2002).…”

Chickpea is a major legume crop grown in the semi-arid tropics and its yields are adversely affected by salinity. In this study, 55 rhizobacterial isolates obtained from the chickpea rhizosphere soil were screened for their salt tolerance. At 3% NaCl concentration, 41.8% rhizobacterial isolates formed colonies varying from 0.5-10 mm size and only 10.9 per cent isolates showed growth at 4% NaCl concentration. Significant growth on ACC supplemented medium plates was observed in 32.7% rhizobacterial isolates. Coinoculation studies with ACC + as well as ACC -Mesorhizobium and rhizobacterial isolates were made on chickpea under chillum jar conditions containing sloger's broth with salt (EC, 4dS/m) and without salt. Coinoculation of Mesorhizobium isolate MBD26 (ACC + ) and rhizobacterial isolate RHD18 (ACC + ) formed 59 nodules/plant and caused 112.9% increase in plant dry weight as compared to uninoculated control plants at 50 days of plant growth, whereas in the presence of salt, only 31.2% increase in plant dry weight was observed in comparison to uninoculated plants. At 80 days of plant growth, coinoculation of Mesorhizobium isolate MBD26 (ACC + ) with rhizobacterial isolate RHD18 (ACC + ) further increased the nodule number (78 nodules/plant) and 141.9% increase in shoot dry weight was observed as compared to uninoculated plants. Thus, it was concluded that coinoculation of ACC + Mesorhizobium and rhizobacterial isolates showed more stimulatory effect on nodulation and plant biomass under normal and salt amended treatments.

“…tion (Jalili et al, 2009;Xu et al, 2003). In addition to the use of traditional breeding and plant genetic engineering with production of transgenic plants (Mayak et al, 2004) and some agricultural engineering measures, such as leaching excess soluble salts from the upper to the lower layer of soil and ameliorating saline soils under cultivation (Qadir et al, 2000), the use of plant growth-promoting bacteria (PGPB) has proved useful in developing strategies to enhance plant growth in saline soils (Bacilio et al, 2004;Markus et al, 2004;Mayak et al, 2004).…”
