摘要
Cadmium(Cd)toxicity in rice is a major concern for human health and the environment,as it can accumulate in rice grains when grown in Cd-contaminated soils.To mitigate the risk of Cd toxicity,it is crucial to cultivate rice varieties with low grain Cd accumulation.In the summers of 2021 and 2022,we conducted Cd analysis on two rice cultivars,Tianyouhuazhan(TYHZ)and Xiushui 14,grown in fields with varying Cd pollution levels.These cultivars were also subjected to hydroponic treatment with or without 1μmol/L Cd for 7 d to assess Cd accumulation,nitric oxide(NO)production。
