Impact of Pink Pigmented Facultative Methylotroph and PGRs on Water Status, Photosynthesis, Proline and NR Activity in Tomato under Drought

Comparative Analysis of two Methylobacterium spp. for Mitigating Moisture Stress Induced by PEG in Early Growth Stages of Tomato

“…Treated seeds of M. thiocyanatum showed earlier germinated percentage at 0 bar without PEG (42.7%) with other treatments showed decline in germination percentage given in table 1. Similar results of improved seed germination and also plant growth promotion on tomato under drought condition was reported by Chandrasekaran et al, (2017). demonstrated the PGP Methylobacterium containing ACC deaminase in the roots of canola (Brassica campestris) and there by reduced the concentration of ACC and ethylene level due to the activity of bacterial ACCd (ACC deaminase).…”

“…treated rice plants showed more catalase activity than control under drought stress. Impact of PPFM enhanced the catalase activity on tomato under drought condition (Chandrasekaran et al, 2017). The catalase activity increased in crops resulted from the foliar application of PPFM (Sivakumar et al, 2017).…”

“…Impact of PPFM enhanced the catalase activity on tomato under drought condition (Chandrasekaran et al, 2017). The catalase activity increased in crops resulted from the foliar application of PPFM (Sivakumar et al, 2017). The treated M. aminovorans (0.11min -1 g -1 leaf tissue) and M. thiocyanatum (0.16 min -1 g -1 leaf tissue) peroxidase values were reduced as compared to un-inoculated control (1.24 min -1 g -1 leaf tissue) given in table 3.The results were in accordance with the finding of showed that the inoculation of Methylobacterium sp., significantly enhanced the peroxidase enzymes on groundnut.…”

Impact of Pink-pigmented Facultative Methylotroph on Physiological, Growth Analytical Traits And Yield of Tomato (solanum Lycopersicum) Under Drought Condition

“…The positive effect of PPFM on leaf water potential can probably be associated with synthesis of compatible osmolytes like proline. Foliar application of PPFM (2%) increased the proline content by 11.34 percent in tomato [5]. Plant growth regulators like benzyl adenine and brassinolide significantly increased leaf water potential in soybean under water deficit condition [11].…”

“…The work [4] reported that the PPFM was found superior in improving stress tolerant index and catalase enzyme activity which can protect the plant under abiotic stress condition. Foliar spray of PPFM was found to superior in improving relative water content ultimately improve the drought tolerant capacity in tomato [5]. The group of scientists [6] suggested that the foliar spray of salicylic acid improves drought tolerant capacity of chick pea under drought condition.…”
