通过对成林及未知性别的幼株过氧化物同工酶谱的分析表明，酶谱从阴极到阳极均可分为３个区．成株雌雄株间的性别差异明显而稳定地反映在Ｂ区和Ｃ区；未知性别的幼株分为Ｃ区具有谱带和不具谱带两种酶谱类型，且与成株的酶谱有密切的相关性．可以认为，过氧化物同工酶可以作为构树早期性别鉴定的指标，用于幼株的早期性别鉴定．酶活性在性别间也有不同，表现为雌株高于雄株，与酶带数量及强度基本一致．
The analysis of peroxidase isoenzymes of young plantlets with unknown and unknown genotypes showed that the enzyme spectrum can be divided into three regions from cathode to anode. The sex differences between adult and male plants were clearly and stably reflected in the B and C zones. There were two zymogram types with and without bands in the unidentified young plants, which were closely related to the zymogram of adult plants Relevance. It can be considered that peroxidase isozymes can be used as an indicator of the early identification of the tree structure for early identification of young plants. Enzymatic activity is also different between the sexes, showing that the female plant is higher than the male plant, and the quantity and intensity of the enzyme band are basically the same.
