interfascicular cambium

1

As the vascular cambium was initiated , the interfascicular cambium was formed on the adaxial side of secondary phloem produced by the cambium . phloem developed well ;

但是当维管形成层形成时，束间形成层在初生乳管的近轴一侧产生，因而随着次生形成层的活动，初生乳管被定位于次生韧皮部远轴一侧。

With the progressive development of stem , the activity of vascular cambium began . The fascicular cambium differentiated into secondary xylem and secondary phloem , while the interfascicular cambium only differentiated into wide ray of parenchyma tissue .

随着茎的继续发育，维管形成层开始活动，由束中形成层产生次生韧皮部和次生木质部分子；而束间形成层仅产生薄壁细胞组成宽的射线。
