NMR was used to study the collenchyma and parenchyma cell walls of celery.
NMR showed the differences between collenchyma and parenchyma cell walls.
Arabinan signals were more evident in the collenchyma spectrum.
Galactan showed a much stronger resonance in the parenchyma spectrum.
Non-esterified pectin has a greater role in cell–cell adhesion in collenchyma.
