Abstract—The plant could adapt to heavy metal conditions in soil I. INTRODUCTION
to some extent. To study the adaptation process of rice plants
In recent years, heavy metal pollution of ecosystem is an

increasingly important environmental problem. In heavy metal
soil on metabolism of rice (Oryza sativa L.) roots were
polluted soil, plant growth monly inhibited. Rice (Oryza
investigated by soil pot experiments at tillering, booting and
sativa L.) plant is one of the world's major grain crops. For
