摘　　要：采用人工HF熏气法,研究HF对金华佛手(Citrusmedicavar.sarcodactylisSwingle)叶中丙二醛(MDA)含量、电导率、超氧化物歧化酶(SOD)、过氧化物酶(POD)及纤维素酶活性、乙烯释放速率的影响。结果表明,HF熏气使佛手叶中MDA含量、电导率持续上升,SOD活性先大幅度下降后稍有回升,POD、纤维素酶活性持续上升,乙烯释放速率先上升后下降。Using the method of artificial fumigation with hydrogen fluoride ( HF ), the effects of fluoride on fingered citron were researched. Some physiologica l and biochemical characters were determined, including the electric conductivit y, malondiadehyde (MDA) content, superoxide dismutase (SOD) activity, peroxidase (POD) activity, cellulase activity, the rate of ethylene production in the leave s of the fingered citron (Citrus medica var. sarcodactylis Swingle). The resul ts showed that in the treated leaf with HF fumigation,electric conductivity and MDA content increased, POD and cellulase activities increased, SOD activity dec reased at beginning and increased thereafter,while, the rate of ethylene releas e went up at first, and decreased at last.
