摘  要：
2014年,根据千年桐的单株结果数、单株产果量、树体大小和树形、果实聚集度等表型指标,在湘南地区筛选出30株初选优树。2015年,以千年桐的鲜果单果重、鲜果出籽率、干籽出仁率和干仁出油率等为评价指标,以此4项指标的均值、标准差和极差建立了千年桐优树种实品质综合评价体系,从中筛选出19株种实品质优良的优树,其中:一级优树4株,4项指标的测定均值分别为58.61g,29.37%,60.29%,61.18%,分别为30株初选优树的109.51%,100.86%,118.56%,127.64%;二级优树9株,4项指标的测定均值分别为54.88 g,29.80%,54.69%,51.39%,分别为30株初选优树的102.35%,102.34%,107.55%,107.22%;三级优树6株,4项指标的测定均值分别为58.88g,28.05%,49.23%,47.12%,分别为30株初选优树的109.81%,96.33%,96.81%,98.31%。此研究为湘南地区千年桐优良种质资源选择提供了技术方法 ,也为千年桐优良无性系的繁育打下了良好的基础。

摘  要：
30 optional trees were selected out by using the visual method,a comprehensive evaluation system was established based on fresh fruits weight,seed rate in fresh fruit,kernel rate in dry seed and oil rate in dry kernel. Furthermore,based on the evaluation system,19 superior trees were selected out from the 30 shortlisted trees. In the superior trees,mean value of the four indexes of the four trees at Grade Ⅰwere 58. 61 g,29. 37 %,60. 29 %,61. 18 %,respectively which were 109. 51 %,100. 86 %,118. 56 % and127. 64 % of the optional trees. Mean value of the four indexes of the nine trees at Grade Ⅱ were 54. 88 g,29. 80 %,54. 69 % and 51. 39 % respectively,which were 102. 35 %,102. 34 %,107. 55 % and 107. 22 %of the optional trees. Mean value of the four indexes of the six trees at Grade Ⅲ were 58. 88 g,28. 05 %,49. 23 % and 47. 12 %,respectively,which were 109. 81 %,96. 33 %,96. 81 % and 98. 31 %. In conclusion,the comprehensive evaluation system was a scientific way for superior tree selection of A. montana in the south of Hunan.
