Muthulingam Muthukumaran

World News of Natural Sciences > 2022 > 40 > 13-25

Aluminum trivalent (Al3+), which commonly occurs on 40% of arable land, is highly phytotoxic to crop growth and yield in acidic soils. As one of the major pollutants in the atmosphere, this element reduces chlorophyll activity, CO2 assimilation, and photosynthesis. Rice is a staple food crop in India and Asian countries. A widely recognized metal toxicity of rice (Oryza sativa) includes soluble aluminum...
