Created a new term that is a child of vascular leaf initiation stage (PO:0001051):
vascular leaf primordium polarity determination stage (PO:0025572): A vascular leaf initiation stage (PO:0001051) during which the vascular leaf primordium (PO:0004725) develops an adaxial side (PO:0004726) and an abaxial side (PO:0004725).
Parent term:[plant-ontology-po-term-requests:#556]
Propose comment: The vascular leaf primordium adaxial side (PO:0004726) is the closest side to the meristem.
Revised definition based on POC Call 10-1-13:
A vascular leaf initiation stage (PO:0001051) during which the vascular leaf primordium (PO:0004725) develops an adaxial side (PO:0004726) and an abaxial side (PO:0004725).
Revised comment: The vascular leaf primordium adaxial side (PO:0004726) is the side proximal to the axis of the vegetative shoot apical meristem (PO:0020148), while abaxial side (PO:0004725) is the distal side.
