auxin

Auxin plays a key role in regulating wood formation through its effects on cambial activity and vascular tissue differentiation in plants: controlling the period of cambial activity, maintaining the morphology and arrange orientation of fusiform cells, regulating the differentiation of phloem and xylem.

生长素在形成层活动和维管组织分化中起着极其重要的调控作用，包括：控制形成层活动周期，维持纺锤状细胞的形态和排列方向，控制木质部和韧皮部的分化。
