In order to explore the toxicity of Cd to rice seedling growth, including the longest root , root length, the influence of different plant physiological traits of two rice cultivars ——Aijiaozhenuo (2) Bayuebai were studied with roots exposed to different Cd concentration in hydroponic culture. The results show :(1) Cd stress significantly inhibited the growth of Aijiaozhenuo (2) and Bayuebai rice root . When Cd was less than or equal to 0.5mg/L, it had little effect on the growth on rice root of Aijiaozhenuo (2), but significantly inhibited the growth of rice root of Bayuebai .When the Cd is greater than 0.5mg/L, the resistance of Aijiaozhenuo (2) to Cd is better than Bayuebai.(2) the rice seedlings of Bayuebai grow slowly under Cd stress, and the rice seedlings in Bayuebai grow weaker than Aijiaozhenuo (2).
