摘要
赣皖乌头肥大直根的初生木质部为二原型，中央为木质部。在赣皖乌头根次生结构形成的过程中，先在次生韧皮部内产生分生组织，然后在初形成的次生木质部中产生异常形成层，分裂形成赣皖乌头根的异常结构。在异常结构形成的过程中，次生韧皮部内分生组织从多处向内凹陷，与异常形成层围成多圈，其中有一层细胞特化为内皮层，将原生中柱转变成裂生中柱。
The primary xylem of plump taproot of Aconitum finetianum is the diarch with xylem in the center.In the action of the secondary structure of the herb ,the meristem is first produced in the secondary phloem,then the anomalous cambium is produced in the secondary xylem forms a new and splits into anomalous structure.In the action of anomalous structure of the herb,the meristem in the secondary phloem sinks inwardly from many sites,and forms many rings with the anomalous cambium.One of these rings forms a special endodermis and the protostele turns into the schizogenous stele.
