norway spruce meaning in Chinese
【植物；植物学】挪威云杉 (Picea abies)。
Examples
- 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。 - Microarray analysis and plantlets regeneration of the transgenic norway spruce ( picea abies ) for low - content lignin norway spruce is one of the two most important forest tree species in europe and the preferred species for pulp manufacture
挪威云杉( piceaabies )是欧洲的主要用材树种，也是重要的造纸原料树种。其木材的主要成分除纤维素外，还有15 - 36的木质素。 - Furthermore the expressions of all the genes in a representative sample were examed by the recently developed method of hybridization to cdna arrays . this was intended to strengthen the theoretical background for the screening of norway spruce genotypes with low lignin content . the calli of the transformed sublines a78 - 3 , a78 - 4 , a78 - 5 and the untransformed control a95 : 88 : 22 were successfully induced to form mature embryos from which plantlets were established
以转基因亚系a78 - 3 、 a78 - 4 、 a78 - 5和未转基因对照a95 : 88 : 22的细胞愈伤组织为实验材料，以dkm和lp - m熟化培养基培养五周后，再以1 4sh萌发培养基培养四周，成功地诱导形成了胚胎，并再生成新的小植株，萌发成活率达到80 。 - Lignin composes about 15 ~ 36 % by dry weight in norway spruce wood and has to be removed in chemical pulping for the manufacture of high quality paper . a slight decrease of lignin in wood ' s is estimated to significantly reduce the consumption of environmentally harmful chemicals during chemical pulping
木质素的存在影响到纸浆和造纸的质量，所以在木材加工成纸浆的过程中，必须用大量的化学物质除去它，这样不但增加生产成本，而且在处理过程中会给环境造成很大的污染。
