摘要

为探讨湿地松家系苗期生长表现，以湖南省汨罗市桃林林场国家湿地松良种基地湿地松无性系种子园的36个半同胞家系子代苗为研究对象，在湖南省桃源县进行试验，对1年生苗木的苗高和地径生长进行测定与分析。结果表明，家系间苗木的苗高和地径生长差异显著，其中苗高生长大于对照且有极显著差异的有：0-1027、0-456、II-101、0-761、11-16、0-53、7-245、25号、11-13等9个家系；地径生长大于对照且有显著差异的有：25号、Ⅰ-10、0-464、Ⅱ-101、3-1、0-615、7-245、8-126等8个家系。

Abstract

In order to select superior families ofPinus elliottii , seedling height and basal diameter of 1-yearoldPinus elliottii of 36 half-sib families in fine variety base clonal seed orchard of the State-owned Taolin Forestry Station were studied in this paper. The results showed that: there were significant differences in seeding height and basal diameter. The optimal families in seedling height were 0-1027, 0-456, II-101, 0-761, 11-16, 0-53, 7-245, 25,
