The taproot develops from the radicle of the seed. Only young trees have main roots and real root necks. The vegetative propagation of trees comes from adventitious buds on the mother stem, such as cutting propagation of grapes and figs, low-rootstock layering propagation of apples, high-pressure propagation of litchi and longan, stolons of strawberries, etc. Or adventitious buds from the mother root, such as jujube, pomegranate, cherry, etc.

Rooting: Roots that occur in fixed parts of plants, including main roots and lateral roots.

Adventitious roots: Roots produced by stems, leaves, old roots and hypocotyls, and their occurrence positions are not fixed.

When seeds germinate, radicle is the first root to break through the seed coat and grow downwards, which is called main root and the earliest root in plants. When the main root grows to a certain length, many lateral roots are produced from the inside at a certain position, which is called lateral roots.
