Abstract:
The function and chemical makeup of the plants that make up heavy metals vary greatly. Due to their role as cofactors, ability to trigger enzyme reactions, ductility, conductivity, and cation stability, heavy metals are crucial for plants. The harmful effects of non-essential metals, such as Cd, Ni, As, Hg, and Pb, can be seen even at low concentrations. The release of heavy metals into the environment happens as a result of volcanic activity, rock weathering, home use, agriculture, medicine, and technological application. Heavy metal pollution exist due to industrial, domestic, agricultural, medicinal, technological application and events like weathering of rocks, volcanic application the released of heavy metal occurs in ecosystem. The present study was conducted to observe heavy metal i.e. cadmium toxicity on Prosopis cineraria. Cadmium is released mainly from nickel-Cadmium batteries, fossil fuel combustion, coating and plating cement production. Certain chemicals hormones were used in order overcome the heavy metal stress conditions from the plant. Prosopis cineraria is a desert plant. It usually grow better in dry places. Chemical hormones gallic acid and sodium nitroprusside were used to compensate the effect of cadmium on Prosopis cineraria. The trail of plant was set up in the Department of Botany, Islamia University Bahawalpur. The trial was set up for eight weeks. Plant seedlings grow well in that duration. Morphological and anatomical features of plant were observed to see the effect of sole heavy metal and its combination along with hormones on plant. It is observed in the study that the growth of plant under heavy metal stress is quite decreased in comparison with application of heavy metal along with hormones. Plant height, growth, number of leaves, nodes, and spines were shown reduced in application of sole metal upon. The heavy metal stress slightly got reduced when gallic acid was applied. Similar effect was seen with sodium nitroprusside along with metal. But the plant had shown great results when combine effect of hormones were applied along with metal. It means that hormones alleviate cadmium toxicity from Prosopis cineraria.
