• Primary phloem phloem derived from the procambium in the young plant
  初生韧皮部：指幼嫩植物中来源于原形成层的韧皮部。
• Protophloem the first - formed primary phloem , differentiated from the procambium in the region just behind the meristem
  原生韧皮部：最早形成的初生韧皮部，由位于分生组织中的原形成层分化而来。
• We have observed the following characteristics of anatomical structure and development : ( 1 ) the primary roots belong to archetype and the lateral roots occur in the position toward the xylem of the vascular cylinder ; ( 2 ) the root endodermis consists of thicken casparian strips , and there are from two lo four layers parenchyma cells near the pericycle ; ( 3 ) the pith and resins canals are absent in the toots ; ( 4 ) secondary structure occurs in the root hair zone , and vascular cambium is formed from the parenchyma cells between the primary xylem and primary phloem ; ( 5 ) tanning materials are abundant in pericycle cells and phelloderm cells ; ( 6 ) sclereids are found in secondary phloem , and rays are rather rich in secondary xylem
  结果表明：气生不定根具有以下结构特征和发育特点： ( 1 )根为二原型，侧根正对着木质部发生； ( 2 )幼根内皮层细胞具凯氏带加厚，维管柱内紧挨中柱鞘内侧具有2 ~ 4层大型薄壁细胞； ( 2 )根中无髓和树脂道； ( 4 )次生结构发生于根毛区，维管形成层由初生木质部和初生韧皮部之间的薄壁细胞转化形成； ( 5 )中柱鞘和栓内层细胞富含单宁类物质； ( 6 )次生韧皮部有石细胞，次生木质部射线发达。
• More anthraquinone compounds was distributed in pith ray cells and the tissues of mature stem suchas bundle sheaths in large - scale vascular bundle , primary phloem and primary xylem than that in young stem . [ conclusion ] the distribution of anthraquinone compounds in the stem was of multilocus
  结果随着茎的不断成熟，在茎的表皮、近表皮的1 ~ 2层皮层细胞及较内部皮层中，不同程度地增加贮藏和积累了一定数量的蒽醌类化合物，成为茎外部贮藏和积累蒽醌共化合物的主要结构部位成热茎大型维管束的维管束鞘、初生韧皮部、初生木质部等组织和髓射线细胞分布了比幼茎多的蒽醌类化合物。
