Assessment of Pb and Ni stress on the physiology and growth of Rosa indica L

Abstract

Heavy metal pollution in the environment is a growing concern with far-reaching consequences for ecosystems and human health. This study provides an overview of the effects of heavy metal stress on aromatic plants, emphasizing physiological responses and
potential implications. It focuses on Pb and Ni, two prevalent and toxic heavy metals. Aromatic plants, known for their diverse secondary metabolites, play a pivotal role in various industries, including pharmaceuticals, perfumery and culinary applications. The
plant selected for this study was Rosa indica (common Indian rose). It was grown in controlled (without heavy metals) as well as contaminated soil (Ni and Pb treated). Aromatic plants are known for their ability to accumulate heavy metals within their tissues, but these heavy metals also have negative impact on plants physiology and their biomass production. The research showed that different Ni doses had less negative impact on plant height and biomass compared to different Pb doses.
