Abstract

Heavy metals are creating big challenges for the scientific community because it creates many problems in which some of them are the absorption and translocation of water and minerals which is a basic need of any plant for normal growth and development. Hence to understand its severity a pot-based heavy metal study was carried out to investigate the deteriorative impact of HgCl2 and CdCl2 on morphological and yield-attributing traits in the Indian mustard variety T-59. To evaluate the impact of HgCl2 and CdCl2, plant height (cm), fresh and dry weight plant-1 (g), total leaf area Plant-1, LAI, CGR, and SPAD reading, the average length of siliqua, the number of siliqua plant-1 and seeds siliqua-1 were considered. The results of the current study indicated the gradual reduction in the growth of entire traits studies concerning the elevation of concentrations of both heavy metals ranging from 1.5 to 5.0 mM. Among the treatments, the highest reduction was detected in T4 of both heavy metals. The maximum % reduction was recorded at 30 DAS compared to 60 and 90 DAS in the entire set of traits while the comparative analysis among the heavy metal (HgCl2 and CdCl2) indicated that HgCl2 is more toxic compared to CdCl2 for the morphological traits of Indian mustard.

Conclusion

The findings of the present investigation are based on HgCl2 and CdCl2-inducedstress on morphological traits, growth analysis, and yield attributing characters in mustard. The findings of the results can be concluded as the concentrations of both the heavy metal increased, and a gradual reduction in the entire traits was detected. Thus, the growth was stunted and yield attributes were attempted limited growth. Additionally, it can also be concluded that the heavy metal HgCl2 was found to be more harmful than cadmium (CdCl2) in terms of its influence on growth and development. Further studies could focus on developing strategies to reduce the influence of heavy metal stress on crop growth and yield.
