Salinity amelioration and plant growth promotion by Paenibacillus castaneae in tomato

Abstract:

The present study stated that salt-tolerant plant-associated Paenibacillus castaneae. enhance plant tolerance to salinity. The treatment using P. castaneae strain presented noticeable but varying effects on plant growth under and often displayed a significant increase in germination percentage, root and shoot length, and other growth parameters of tomatoes compared to those in the non-inoculated control.
The physiological responses viz., proline, relative water content and chloprphyll showed were increased as compared with the control treatment better growth promotion significantly by the application of P.castaneae in the saline environment. The strategy against oxidative damage by increasing antioxidant enzyme activities under high salinity stress. These results suggest that salt-induced oxidative stress in tomatoes is generally counteracted by enzymatic defense systems stimulated under harsh conditions. The field experiment was conducted with the laboratory results obtained in this P. Castaneda along with Azospirillum and phosphobacteria was studied on tomato cultivars under field conditions. The field study results confirmed that 75% recommended N + 75% recommended P + Azospirillum + Phosphobacteria + Paenibacillus strain exhibited grateful results in improving tomato plant growth and yield under salinity stress.
