文摘

A new system of morphotypes of fertile long shoots in the genus Pinus is proposed.

Six morphotypes of fertile long shoots in Pinus form more than one node per year.

All 120 species of Pinus are classified according to long shoot morphotypes.

Long shoots in juvenile individuals of Pinus form less clear-cut or transitional forms.
