Other claims from this paper (4)
- Observation Cultivated leaves visually resembled early leaves of the wild subspecies.
- Observation Early nodal leaf development was similar between the subspecies.
- Observation Very young leaves at later nodes were more similar between subspecies than to early node leaves within plants.
- Mechanism Later mature leaf shapes masked early similarity because of subsequent allometric growth differences.
