板栗不同品种叶片的过氧化物酶活性存在着差异,矮化型品种的过氧化物酶活性明显高于一般品种。所测品种叶片的过氧化物酶活性均与冠径、树高、干周、新梢长度呈负相关。因此,可以把叶片过氧化物酶活性作为矮化型板栗品种早期预选的生化指标之一。 There were differences in the peroxidase activities of different chestnut varieties, and the peroxidase activity of dwarf varieties was significantly higher than that of common varieties. The activities of peroxidase in leaves of tested cultivars were negatively correlated with the crown diameter, tree height, dry week and shoot length. Therefore, leaf peroxidase activity could be used as one of the biochemical indicators of early pre-selection of dwarf chestnut varieties.
