Assessment of Heavy Metals Tolerance in Leaves, Stems and Flowers of Stevia Rebaudiana plant

Stevia has become rather widespread over a wide range of climatic locations around the world and can apparently be successfully grown under different cultivation conditions. Heavy metal accumulation of Stevia extract is dependent on obtaining heavy metals from the soil and water. Heavy metals from p...
