2、论依据。【方法】对黑荆试验林全部林木进行每木检尺,采用GB2615-1981栲胶原料与产品榆验方法(皮粉法)测定其单宁含量和纯度,分析黑荆家系单宁产量、树皮干重、树高、胸径和材积等生长性状间的差异及其相关性。【结果】黑荆家系间树高变幅较小,差异不显著(P>O.05);家系间的材积及树皮干重在0.1水平下差异显著;胸径及单宁产量在各家系间差异显著(P3、树皮干重、树高、胸径、材积等生长性状间存在中度或高度正相关。以单株单宁产量为主要选择指标,单株材积为辅助选择指标,共选出8个优良黑荆家系可用于生产,入选家系的平均单宁产量及平均材积分别比参试家系总平均值高39.07%和30.72%。【结论】在黑荆育种进程中可同时考虑对生长性状和单宁产量进行改良。关键词:黑荆树;单宁产量;生长性状;半同胞家系;家系选择中图分类号:$722.5文献标志码:A文章编号:2095一1191(2015)10—1862—051h1●●n●●●n●1rrellmlnarVscreenlngoIACa4、cJameaI?nsJJlamilywithhightanninyieldLIJuanl,JIANGYi”,CHENYun—feng2,LIUXiao-weil,WANGYon91,DENGYu-hua2(1GuangxiForestryResearchInstitute,Nanning530002,China;2GuangxiHuangmianForestFarm,Luzhai,Guangxi545600,China)Abstract:【Objective】ThefineAcaciameamsiifamilieswi5、thhigh-yieldtanninwerescreened,inordertoprovidetheoreticalbasisforgeneticimprovementandvarietybreedingofAcaciameamsiiforextractingtannin.【Method】Thegrowthvolumeandbarkthicknessof47haft—sibA.meamsiifamiliestreeweremeasuredinGuangxiHuangmianforestfarm.Andtheconten6、tandpurityoftanninweredeterminedbyGB2615—1981testingmethodoftanninextractrawmateri—alsandproducts(hidepowdermethod).Thenthedifiereneesandcon'elationsamongdifferentgrowthtraitsviz.,tanninyield,dryweightofbark,treeheight,DBH,timbervolumeandSOonwereanalyzed.【Result7、】Theresultsshowedthata—mongA.meamsiifamilies,therewerenonsignificantdifierencesintreeheight(P>0.05),thereweresignificantdifferencesifltimbervolumeanddryweightofbarkat0.1level.thereweresignificantdifferenees(P<0.05)orextremelysignificantdiffereneesinDBH.tannincon8、tentandyield(P<0.01).ComparedwithtreeheightandDBH,thevariationcoeffieientofdryweightofbarkandtanninyieldwasmorethan63.00%.SOmoregeneticvariationsexistedindryweightof1
