Salinity is an obstacle to global agriculture, as it affects plant growth and development. Chitosan (CTS) has been suggested a regulator alleviate environmental stresses. In this study, the morphological biochemical responses of chitosan application (75 mg L−1) on maize seedling under salt stress (150 mM) were conducted with hydroponic experiment. The results exhibited that CTS effectively recovered salt-inhibited biomass accumulation root architecture by increasing chlorophyll content photosynthetic assimilation reducing sodium in shoots roots 25.42% 5.12% compared NaCl treatment. Moreover, salt-induced oxidative was alleviated activities antioxidant enzymes superoxide dismutase, catalase, ascorbate peroxidase, peroxidase ascorbate. Correlation analysis partial least squares (PLS) revealed morphology play key roles for seedlings response stress. Based these results, recommended effective approach enhance tolerance

Abstract Background Soil salt stress is a problem in the world, which turns into one of main limiting factors hindering maize production. Salinity significantly affects root physiological processes plants. There are few studies, however, that analyses response to terms development anatomy and respiration. Results We found leaf relative water content, photosynthetic characteristics, catalase activity exhibited decrease treatments. However, treatments caused superoxide dismutase activity, peroxidase malondialdehyde Na + uptake translocation rate be higher than control The detrimental effect on YY7 variety was more pronounced JNY658. Under stress, number cortical aerenchyma salt-tolerant JNY658 plants control, as well larger cell size lower file number, all help maintain biomass. total respiration two varieties exposed treatment, while alternate oxidative higher, significant. roots net K efflux rates were those where strength from remarkable. increase reduced toxicity helped its ion balance. Conclusion These results demonstrated incur relatively low metabolic cost required establish aerenchyma, rate, it also increased thereby counteracting damage growth. In addition, surface decreased, rest plant constrained level accumulation leaves under thus preempting salt-stress induced impediments formation shoot
