铅胁迫下不同茶树的生理响应及其亚细胞水平铅分布特性分析
Physiological Response and Subcellular Distribution in Different Tea Plants Under Pb Stress
摘要
Abstract
In order to analyze physiological response to Pb stress and Pb distribution characteristics in subcellula tissues of different tea plants,this paper did research taking Tieguanyin and Rougui as materials by pot planting method,so as to provide theoretical basis for studying toxicity mechanism of heavy metal to tea plants and for self-defense of tea plants.The results showed that activities of leaf blade superoxide dismutase (SOD),peroxidase (POD),catalase (CAT) declined with the increase of Pb concentration,and the tolerance of Rougui to Pb stress was higher than that of Tieguanyin.There was no significant differences between the total Pb contents in subcellula tissues of the 2 tea plants under the same concentration of Pb stress.In addition,Tieguanyin increased Pb2+ propertion in cytosol and organelles to reduce Pb2+ toxicity,while Rougui mainly improved binding ratio of Pb2+.Therefore,there was different detoxification patterns for different tea plants under Pb stress.关键词
