杨树茎高-直径多阶段生长的QTL定位分析
QTL mapping analysis for multi-stage height-diameter growth of Populus
[目的]探究杨树生长过程中在不同阶段之间过渡的发育遗传程序,结合树木生长过程中性状间的相互作用关系,对茎高-直径复合性状进行QTL定位,深入解析控制复合性状阶段生长及过渡的遗传结构,对森林培育以及改善林木生产具有重要意义。[方法]本研究以64个全同胞杨树群体及其父母本为实验材料,获取茎高和直径1-24年的动态生长数据,利用Lotka-Volterra(LV)微分方程组描述幼年期两个性状的相互作用,2个logistic函数分别描述成年期生长发育,建…查看全部>>
[Objective]The purpose of this study was to explore the developmental genetic program of the transition between different stages in the process of poplar growth.Combined with the interaction relationship between traits growth,QTL mapping was carried out on the composite traits of height and diameter to analyze genetic structure of multi-stage growth and transition,which is of great significance for the forest cultivation and improvement of forest production.…查看全部>>
