在木质部母细胞完全恢复活动之前，形成层纺锤状原始细胞的分裂和韧皮部细胞的分化已经开始。
Before xylem mother cells reactivated completely , the dividing fusiform cells in cambium and new phloem cells had appeared at the same time .

它们分别发育转化为维管形成层中的纺锤状原始细胞和射线原始细胞.结果表明：①掌叶木种群径级和高度结构呈纺锤状，为衰退型种群。
At the early stage of primary growth , there are two types of cells in the vascular meristems , one is longer and the other is shorter . All results indicate : ( 1 ) The structure of diameter and height shows spindle shape belonging to decline population .
