摘　　要：研究了橄榄不同材料的多酚氧化酶(PPO)活性,比较了AC和PVP等附加物质对橄榄PPO作用的影响。结果表明:橄榄芽的PPO活性比较高,与对比材料茶叶新梢相比,其PPO活性要高出2-5倍;AC和PVP的配合使用对抑制橄榄材料的褐变有协同作用。本试验结果为组织培养中橄榄外植体材料的选用以及抑制褐变物质的选择提供了依据。In this experiment, the activity of polyphenoloxidase （PPO） in different materials was studied in Chinese olive （Canariurn alburn）. The results showed that the activity of polyphenoloxidase in buds was 2 - 5 times higher than that in new shoots of tea plant for comparison; there was coordinated function between AC and PVP to control browning of explants, which provided a new way to select explants of C. album in tissue culture and substances of controlling browning.
