【摘要】 富士苹果不同品系在宁夏已引种多年 ,很受人们的喜爱。本文采用聚丙烯酰胺凝胶电泳 ,研究了宁夏引种的富士苹果 ,共 6个品系的过氧化物酶同工酶谱的数量和活性相对含量 ,结果表明 :在不同的品系间 ,不同营养器官间 ,酶带的数量、级别、活性相对含量都存在着较为明显的差异 ,各品系有着独特的过氧化物酶同工酶谱 ,这些都是基因引起的遗传变异 ,非环境所致。该研究对于富士苹果不同品系更进一步地深入研究 ,丰富果树遗传育种科学进展 ,指导果树生产等都具有一定的参考价值和现实的启示意义更多还原

【Abstract】 Some strains of apple Fuji have been introduced into Ningxia for many years, which has been liked by people The paper reported the study on the quantity and relative content of activity of peroxidase isozyme in six strains of the apple The result showed that it had an obviouse different in quantity, class and relative content of the isozyme belt between different nutrient-organs of the strains Each strain existes some special peroxidase isozyme belts The genetic variation was caused by genes, not by environment The research subject studied many strains of apple that increased the content of genetics and breeding science on fruit tree It provided a reference for the production of fruit trees更多还原
