森林树种生物多样性的保护是当代全球关切的问题之一。要保存森林资源，也就要保存森林物种，更重要的是保存构成森林主体的树木。而要保存树种，首先要保存树种内性状的多样性，因为种内多样性消失是物种消失的先导。同名性状多样性，是决定或控制同名性状的等位基因决定的，? The conservation of forest tree biodiversity is one of the issues of contemporary global concern. The preservation of forest resources requires the preservation of forest species and, more importantly, the preservation of the trees that make up the body of the forest. To conserve species, we must first preserve the diversity of traits in the species, because disappearance of intraspecific diversity is the precursor to the disappearance of species. Diversity of traits of the same name, is to determine or control the characters of the same name determined by the allele?
