Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Carbon dioxide

William Armstrong mostly deals with Botany, Aerenchyma, Aerenchyma formation, Phragmites and Aeration. His Botany study incorporates themes from Oxygen transport and Soil water. William Armstrong conducted interdisciplinary study in his works that combined Aerenchyma and Rumex palustris.

William Armstrong focuses mostly in the field of Phragmites, narrowing it down to topics relating to Rhizome and, in certain cases, Sprouting. His Aeration research is multidisciplinary, incorporating perspectives in Physiological Adaptations and Soil waterlogging. As a member of one scientific family, he mostly works in the field of Photosynthesis, focusing on Carbon dioxide and, on occasion, Secondary thickening, Xylem and Environmental engineering.

His most cited work include:

  • Aeration in Higher Plants (1152 citations)
  • THE ANATOMICAL CHARACTERISTICS OF ROOTS AND PLANT RESPONSE TO SOIL FLOODING (639 citations)
  • Formation of Aerenchyma and the Processes of Plant Ventilation in Relation to Soil Flooding and Submergence (558 citations)

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

William Armstrong focuses on Botany, Shoot, Aeration, Phragmites and Aerenchyma. Botany is often connected to Horticulture in his work. In his research on the topic of Shoot, Oxidative phosphorylation is strongly related with Xylem.

The various areas that he examines in his Aeration study include Hypoxia and Convection. His Phragmites research incorporates elements of Oxygen transport, Cell wall, Static pressure and Callus. Menyanthes, Waterlogging and Agronomy is closely connected to Soil water in his research, which is encompassed under the umbrella topic of Aerenchyma.

He most often published in these fields:

  • Botany (75.49%)
  • Shoot (32.35%)
  • Aeration (26.47%)

What were the highlights of his more recent work (between 2006-2020)?

  • Botany (75.49%)
  • Respiration (26.47%)
  • Shoot (32.35%)

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

His primary scientific interests are in Botany, Respiration, Shoot, Aeration and Respiratory system. His Botany study integrates concerns from other disciplines, such as Biophysics and Phragmites. William Armstrong combines subjects such as Hypoxia, Stele and Anoxic waters with his study of Respiration.

His study explores the link between Shoot and topics such as Rhizome that cross with problems in Equisetum telmateia. His research investigates the connection between Aeration and topics such as Convection that intersect with problems in Chemical physics and Soil water. His Respiratory system research includes themes of Respirometry, Physiology and Respiration rate.

Between 2006 and 2020, his most popular works were:

  • Apoplastic barriers to radial oxygen loss and solute penetration: a chemical and functional comparison of the exodermis of two wetland species, Phragmites australis and Glyceria maxima (117 citations)
  • Plants and flooding stress. (65 citations)
  • Plants and flooding stress. (65 citations)

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

  • Botany
  • Ecology
  • Biochemistry

William Armstrong spends much of his time researching Botany, Shoot, Biophysics, Hypoxia and Plant physiology. He has researched Botany in several fields, including Fermentation and Respiratory system. His research integrates issues of Stele, Partial pressure and Cellular respiration in his study of Fermentation.

As a part of the same scientific study, William Armstrong usually deals with the Cell wall, concentrating on Exodermis and frequently concerns with Aerenchyma. The study incorporates disciplines such as Gibberellin, Plant stem and Photosynthesis in addition to Gibberellic acid. His work carried out in the field of Respiration rate brings together such families of science as Respirometer and Respirometry.
