Examples
- An attractive objective in tree breeding is therefore to reduce the content of lignin
为此，开展木质素含量低的挪威云杉新品种的选育就成为一个迫切需要解决的问题。 - In comparison , the christmas tree in new york ' s rockefeller center is 71 feet tall and has 30 , 000 lights , although it is a real norwegian spruce
相比之下，纽约洛克非勒中心的圣诞树只有71英尺高，上面点缀着3万只灯泡，尽管那是一棵真正的挪威云杉。 - The decrease of lignin has to be achieved without interfering the stability of the tree , the efficiency of water and nutrient transport , and its resistance to pathogen
与绝大多数林木一样，挪威云杉的常规育种周期长达25年以上，而且常规选择育种容易受到自然条件和资源的限制。 - Such conditions would have been especially harsh for a tree adapted to temperate climes , such as the norway spruce , stradivari ' s favorite for making soundboards
这样的环境，对于像挪威云杉这类习惯温暖气候的植物来说，无疑是最严酷的考验，而挪威云杉正是史特拉底瓦里拿来制作共鸣板的不二选择。 - Recent developments in molecular biotechnology are making this possible . in the work described here , three transgenic sublines of embryogenic norway spruce calli : a78 - 3 , a78 - 4 and a78 - 5 were studied
随着分子生物学技术的发展，通过转基因技术有目的地培育出木质素含量低的挪威云杉新品种就成为可能。
