The analysis of the chemical constitutes among sterns roots and leaves of Dracaena cochinchinenis, showed that there' s small amount loureirin A in their extracts, with 0.053mg/g, 0.058mg/g, 0.015mg/g respectively only. Therefore, the roots, stems and leaves of Dracaena cochinchinenis have too low contents of loureirins to be raw materials of dragon's blood.

分析剑叶龙血树根、茎、叶的成分，发现风干的剑叶龙血树根、茎、叶中没有龙血素B的存在，只含有少量的龙血素A，其含量在根、茎、叶中分别为：0.058mg/g，0.053mg/g，0.015mg/g，其含量远低于现行的龙血竭中龙血素A含量不低于2％的质检标准，因此剑叶龙血树的根、茎、叶不能直接用作生产龙血竭的原料。

So, endomycorrhiza was formed betweenD. candidum roots and strain AR-15. There were several nucleoli and nuclei in thecortical cells next to exodermis when a nucleus transfer across the cell wall wasobserved. Sometimes plant roots were damaged by strain AR-15. The microstructure of D.

真菌AR-18倾向于根生长，在根周围形成了一个包围圈，由根被细胞侵入外皮层通道细胞及其相邻的皮层细胞，然后向其他皮层细胞推进；真菌菌丝也可由皮层细胞侵入外皮层细胞。

Hairy roots were induced from tobacco leaves with Agrobacterium rhizogenes LBA1334 harboring agropin type PRil855 and binary vector PIG121HM carrying a kanamycin resistant gene nptll and GUS gene and the good hairy root clones were selected. The root with many root hairs and branches grew vigorously toward all the direction on MS medium without plant hormone and on kanamyain containing medium (km:30mg/L). The structure of the hairy root tip is different from that of ordinary root. Witch was not typical root cap maybe the main cause of losing the geotropism of hairy root. Plantlet regenerated from hairy root when cultured on Ms medium without plant hormone. The nicotine content of the hairy root was little higher than that in the natural roots.

本研究通过发根农杆菌工程菌LBA1334(含有野生型pRi1855质粒和pIG121HM双元载体质粒，编码NPTⅡ基因和GUS基因)转化烟草沙姆逊，获得了具有卡那霉素抗性烟草发状根，并筛选出良好的单克隆株系，该发状根具有典型的发状根特性(多根毛、多分支、在无激素培养基上快速生长)，通过根尖压片分析，烟草发状根不具备典型的根冠；发状根中烟碱含量1.61％稍高于与天然栽培品种母体根的含量(1.5％左右)，发状根向培养液中释放烟碱，释放量最多时占总烟碱量的81.1％；在无激素的培养基上获得了再生植株。

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
