In his most recent research, the most cited papers focused on:

  • Botany
  • Ecology
  • Enzyme

His scientific interests lie mostly in Botany, Recalcitrant seed, Desiccation, Cryopreservation and Horticulture. Norman W. Pammenter combines topics linked to Embryo with his work on Botany. The various areas that he examines in his Recalcitrant seed study include Host, Plant diversity and Germ plasm.

In general Desiccation study, his work on Trichilia dregeana often relates to the realm of Relative species abundance, thereby connecting several areas of interest. His Horticulture research includes elements of Eucalyptus, Permanent wilting point and Stomatal density.
