本研究揭示了杉木雌、雄球花和叶片的PER(过氧化物酶)同工酶在不同时期、产地、林分、个体及无性分株水平上的遗传变异规律.探讨了亲本PER酶谱点位和相对含量与子代生长的性状相关,提出了应用亲本PER酶谱变异,预测个体或群体F_1代生长表现的方法(简称“PG”法).
This study revealed the genetic variation of PER (peroxidase) isozymes in the female, male Chinese flower and leaves of Cunninghamia lanceolata at different stages, producing areas, stand, individual and clonal ramets. Point and relative content were correlated with the growth traits of progeny. A method of predicting the growth performance of individuals or groups of F1 progenies by using PER variation of parents (PG method) was proposed.
