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 木質素的存在影響到紙漿和造紙的質量,所以在木材加工成紙漿的過程中,必須用大量的化學物質除去它,這樣不但增加生產成本,而且在處理過程中會給環境造成很大的污染。 |

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 以轉基因亞系a78 - 3 、 a78 - 4 、 a78 - 5和未轉基因對照a95 : 88 : 22的細胞愈傷組織為實驗材料,以dkm和lp - m熟化培養基培養五周后,再以1 4sh萌發培養基培養四周,成功地誘導形成了胚胎,并再生成新的小植株,萌發成活率達到80 。 |

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 )是歐洲的主要用材樹種,也是重要的造紙原料樹種。其木材的主要成分除纖維素外,還有15 - 36的木質素。 |

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 隨著分子生物學技術的發展,通過轉基因技術有目的地培育出木質素含量低的挪威云杉新品種就成為可能。 |

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 這樣的環境,對于像挪威云杉這類習慣溫暖氣候的植物來說,無疑是最嚴酷的考驗,而挪威云杉正是史特拉底瓦里拿來制作共鳴板的不二選擇。 |
