摘要
在杜仲优树无性系试验测定林中 ,对 4 0个杜仲优树无性系的有效成分含量和生长量进行了测定 ,并分别进行了 Fuzzy一级综合评判 ,然后以有效成分为首选指标并结合生长量指标进行了 Fuzzy二级综合评判 ,对二级综合评判排序前 1 1位的优树无性系的抗性指标进行了测定。通过研究建立了以成分含量为首选指标、结合生长量指标。
In this paper,the active component contents and growth increment indicators of forty selected Eucommia colones which located in experimentally determining forestry were determined and analysed by the first class of the integrated discrimination of Fuzzy.Using the active compoenent contents as the first indicator and combining growth increment,the second integrated discrimination of Fuzzy was carried out.And the resistant indicators of the first eleven fine colones of the second Fuzzy ranking were measured.Based on results,the indicator system of fine Eucommia colones selection was first established.
