摘 要:
香樟(Cinnamomum camphora Presl),樟科(Lauraceae)樟属(Cinnamomum Trew)的优良速生阔叶树种,且材质珍贵,广泛用于城镇的园林绿化和山区造林。1996年中国林科院亚热带林业研究所在浙江的长乐林场开始对香樟的观赏价值和工业油用价值进行了研究,收集了全国各地的200多个种源和家系,建立了种源试验示范林,筛选出部分四季叶相变化较大和芳香油含量较高的种源和家系,迫切需要对这些选育出的优良品种进行大规模繁殖。长期以来香樟都采用播种繁殖,但是樟树品种复杂,且种子繁殖变异多,会产生子代分离现象,并且等待母树结实所需周期较长,导致在生产中存在一些困难。为确保优良遗传性状的稳定,很有必要对香樟的无性繁殖进行较为系统的试验研究。[第一段]

Abstract:
By investigating the key survival and indexes, the resuhs showed : ( 1 ) the stage of the seeding has the most important effective. The survival rate of the cuttings was the highest by using 1-year-old cuttings. The older the cuttings, the lower the survival rate. (2) There was no obviously rules by using ABT. (3) By comparing the results of covering with black & white plastic velum and no covering, the white one is considered better than the two others. In practice work, the type of A1 B1 C2 was better. The concentration of ABT could be reduced, but the time of soaking should be prolonged.[著者文摘]
