Abstract:
To exploring the accumulation and absorption of cadmium (Cd) in Chinese cabbage，atomic absorption spectrophotometry and the Noninvasive Microtest Technology (NMT) were carried out using 26 Chinese cabbage cultivars.This study had initially screened the Chinese cabbage cultivar with the low-Cd accumulation and absorption.The results indicated that the Cd content in the leaves of Chinese cabbage ZBX was higher，while the JL-75 was lower.The root of ZBX with higher Cd accumulation showed a stronger ability of Cd absorption；and the root of the JL-75 with lower Cd accumulation showed weaker ability to absorb Cd2+，indicating that the NMT results of Cd2+ absorption were consistent with the Cd accumulation levels in Chinese cabbages.Linear regression analysis showed that，during the absorption processes in different Chinese cabbages，the absorption rate did not increase with time，and the time points was different when the flow rate reached a stable value.It was suggested that this result could also be the reason of the difference of the Cd absorption ability in Chinese cabbages.This study was significant for further exploring the mechanism of the Cd absorptionin Chinese cabbage and the Cd accumulation in the leaves.
