| 摘 要： | 经生长结实性状测试表明:①用于建园的72个双亲无性系3年生植株结实率为65%,结实株率达30.6%。无性系采穗亲本5年生结实率达90%,说明建园无性系幼龄初始结实性状是正常、良好的。②选自全国7省(区)种源子代林的优树无性系,在邵武地区的气候立地条件下,12年生的植株结实性状,除两广种源结实偏少、湖南种源结实稍多之外,其它各种源无性系结实良好。③选自福建省的优树无性系,无论是闽西南还是闽西北的结实性状均属良好。

| Abstract: | The seeding rates of the 72 parental clonal seedlings at age 3 for building the seed orchard was 65% for the total clonal seeds and 30.6% for individual trees.The seeding rate of scion-producing parents at age 5 was 90%.The seeding traits of the stock at early ages were normal.For the 12-year-old clones of elite first-generation trees from 7 provinces,which were cultivated in Shaowu,Fujian,their seeding performances were generally good except that those from Guangdong and Guangxi were a little less and that from Hunan slightly more.For the clones form Fujian,no matter from the southwest or northwest,their seed setting traits were fairly good. |
