Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Enzyme

His primary areas of study are Botany, Desiccation, Recalcitrant seed, Horticulture and Desiccation tolerance. Norman W. Pammenter has researched Botany in several fields, including Global biodiversity, Habitat and Ecosystem. The various areas that Norman W. Pammenter examines in his Desiccation study include Host, Dehydration and Water content.

Recalcitrant seed is a subfield of Germination that Norman W. Pammenter investigates. His work on Water stress as part of general Horticulture research is frequently linked to Stress, bridging the gap between disciplines. His studies in Desiccation tolerance integrate themes in fields like Agroforestry, Avicennia marina and Aesculus hippocastanum.

His most cited work include:

  • A review of recalcitrant seed physiology in relation to desiccation-tolerance mechanisms (343 citations)
  • A mathematical and statistical analysis of the curves illustrating vulnerability of xylem to cavitation. (336 citations)
  • From Avicennia to Zizania: seed recalcitrance in perspective. (220 citations)

What are the main themes of his work throughout his whole career to date?

The scientist’s investigation covers issues in Botany, Recalcitrant seed, Desiccation, Horticulture and Germination. His work carried out in the field of Botany brings together such families of science as Avicennia marina, Cryopreservation and Dehydration. Norman W. Pammenter works on Recalcitrant seed which deals in particular with Trichilia dregeana.

Norman W. Pammenter combines subjects such as Biochemistry, Germplasm and Radicle with his study of Desiccation. Norman W. Pammenter interconnects Eucalyptus, Photosynthesis and Respiration in the investigation of issues within Horticulture. The concepts of his Germination study are interwoven with issues in Ekebergia capensis, Meliaceae and Oxidative damage.

He most often published in these fields:

  • Botany (68.24%)
  • Recalcitrant seed (40.54%)
  • Desiccation (34.46%)

What were the highlights of his more recent work (between 2012-2021)?

  • Recalcitrant seed (40.54%)
  • Botany (68.24%)
  • Desiccation (34.46%)

In recent papers he was focusing on the following fields of study:

His main research concerns Recalcitrant seed, Botany, Desiccation, Horticulture and Cryopreservation. The study incorporates disciplines such as Desiccation tolerance, Dehydration and Germ plasm in addition to Recalcitrant seed. His Botany study combines topics in areas such as Cytoplasm and Embryo.

His study in Desiccation is interdisciplinary in nature, drawing from both Host, Plant diversity and Water content. The Cryopreservation study which covers Glycerol that intersects with Callus and Zygote. His biological study spans a wide range of topics, including Lipid peroxidation and Oxidative damage.

Between 2012 and 2021, his most popular works were:

  • Preservation of Recalcitrant Seeds (94 citations)
  • Implications of the lack of desiccation tolerance in recalcitrant seeds (60 citations)
  • Intracellular ice and cell survival in cryo-exposed embryonic axes of recalcitrant seeds of Acer saccharinum: an ultrastructural study of factors affecting cell and ice structures. (34 citations)

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. His work in the fields of Germination, such as Desiccation tolerance, overlaps with other areas such as Life span.
