日本落叶松(Larix kaempferi(La-mb.)Carr.)种子园的优种选育工作是通过多种途径实现的,其中人工控制授粉及无性系的杂交是基本工作之一。我们于1982年、1984年、1986年三个年度中在种子园内对日本落叶松花的各发育时期的形态特征进行了观察。特别在1984年对日本落叶松40个无性系进行了全同胞子代测定(控制授粉),即 Larix kaempferi (Larix kaempferi (La-mb.) Carr.) The seed selection of elite breeding is achieved through a variety of ways, of which artificial control of pollination and clonal hybridization is one of the basic work. We observed the morphological characteristics of Japanese larch flower at various developmental stages in the seed orchards in 1982, 1984 and 1986. Especially in 1984, 40 clones of Larix kaempferi were tested for all-sibling progeny (control of pollination), ie
