第四、必须确实保护好鄂西秃杉基因的纯度。鄂西秃杉林受当地环境条件的影响已产生了独特的遗传特性。在尚未弄清楚它的生态条件要求和遗传特性之前,切不可轻易的使鄂西秃杉与其它地区秃杉遗传基因相互混杂。当前引种试验工作还刚刚开始,秃杉生态要求尚未搞清,在这种情况下,轻率的将其它地区的秃杉幼苗、种子引入鄂西秃杉 Fourth, we must really protect the purity of Taiwan’s Avianum flossus gene. The impact of local environmental conditions in Taiwan hippophae rhamnoides has produced unique genetic characteristics. Before it is clear about its ecological conditions and its genetic characteristics, it is not easy to mix the communis of Taiwan communis and other areas with the genetic elements of Taiwania flousiana. The current introduction of test work has just begun, the ecological requirements of Taiwania flousiana has not yet been clarified, in this case, the reckless will other areas of Taiwania seedlings, seeds introduced into Taiwan octopus fir
