Effect of the Pesticide Endosulfan and Two Different Biostimulants on the Stress Responses of Phaseolus leptostachyus Plants Grown in a Saline Soil

Soil salinity and the indiscriminate use of agrochemicals has significantly reduced productivity ‘Chinampas’ agroecosystem in Mexico City. Crop improvement under these stressful conditions may be achieved by soil bioremediation. In this study, we checked effects organochlorine pesticide endosulfan bioremediation with Penicillium crustosum or a citric waste on growth Phaseolus leptostachyus plants saline from Chinampas area. Biochemical markers associated specific stress responses were also determined after one month different substrates. Plant was stimulated soil. Both biostimulants degree affecting plants, as shown increase photosynthetic pigments reduction proline, malondialdehyde (MDA), H2O2 contents, activation antioxidant systems. However, appeared to mitigate oxidative through mechanisms. Endosulfan contamination inhibited seed germination—which reverted control values presence biostimulants—and further decreased plant growth. No clear patterns variation biochemical observed combining biostimulants. any case, P. and/or is recommended improve germination plants.
