现代群体育种的原理表明,日本柳杉的授粉是由多数其他个体的花粉籍风力传播而授精的。由于种子园内同一无性系的繁殖体没有邻接现象,可以认为是随机杂交的。为了证实在随机杂交情况下日本柳杉花粉的授 The principle of modern group breeding shows that the pollination of Japanese cedar is inseminated by the wind of most other individuals. As the seed orchard within the same clonal propagules do not have the adjacent phenomenon, can be considered random hybridization. In order to confirm the cedar pollen given in the case of random hybridization
