摘 要：
为选出适宜湖北省发展的桤木优良地理种源/家系,对桦木科桤木属的15个桤木种源124个家系和江南桤木3个种源2个家系总计18个种源126个家系进行了育苗、造林对比试验,并对苗期生长及造林后的幼林生长进行了年度生长测定调查,通过6 a的观测数据分析,结果表明:桤木各种源、家系高生长迅速,远远优于江南桤木;桤木各种源之间高生长差异不显著,仅有四川剑阁种源家系间呈现出显著差异;有金堂盐井、金堂长乐、金堂淮口、盐亭、珙县等5个种源长势较优,适宜在湖北省推广发展.

摘 要：
This research conducted an assessment,in Hubei Province,of the suitability for popularization,of Alnus provenances/families;they include 15 provenances/124 families of Alnus cremastogyne and 3 provenances/2 families of Alnus trabeculosa.Comparison between their seedlings and saplings over a 6-year-long period indicates that Alnus cremastogyne grows far faster in height than Alnus trabeculosa;that there is no significant difference in height growth among provenances of Alnus cremastogyne except the families of Jiange provenance;and that five provenances including Jingtang and Gongxian grow well and are suitable for popularization in Hubei.
