The growth process of garlic bolt is that after flower bud differentiation, the growth cone elongates and develops into the embryonic form of garlic bolt. When the anchor is about 1 cm high, it is called "umbilical anchor". When the tip of the involucre is exposed from the outlet of the terminal leaf, it is called "exposing the cap" or "shaking the tassel"; When the expanded part of involucre is exposed from the leaf mouth, it is called "exobract" or "outlet"; When the young garlic shoots bend to one side, it is called "hook", which is the appropriate time for the young garlic shoots to be harvested.
