摘    要:对二倍体玫瑰香与加倍后形成的四倍体变异品系的5种器官,分别测定了过氧化物酶活性、多酚氧化酶活性和酚类物质含量。试验结果表明,二倍体玫瑰香品种加倍形成四倍体后,雄蕊、雌蕊和成叶的过氧化物酶活性均极显著降低;雄蕊和雌蕊的多酚氧化酶活性、酚类物质含量也极显著地降低,但成叶和叶柄的多酚氧化酶活性、酚类物质含量却极显著地升高,上述3种生化指标在茎尖上均未表现出差异

关 键 词:玫瑰香葡萄  二倍体  四倍体  生化指标

Abstract:The activities of peroxidase (POD) and polyphenol oxidase (PPO) and the content of five organs in grape (cv.Muscat Hamburg) were examined. It showed that:After diploid plants reduplicated into tetraploid ones,the POD activities in stamen, pistil and mature leaves,the PPO activities and the content of phenolic compounds in stamen and pistil significantly decreased,but PPO activities and the content of phenolic compounds in mature leaves and leafstalks notably increased.There were no differences of three biochemical indexes at stem tip.
Keywords:muscat  Hamburg  grape  diploid  tetraploid  biochemical  index
