Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Halophyte

Irwin A. Ungar mainly focuses on Halophyte, Botany, Salinity, Germination and Horticulture. His Halophyte research is multidisciplinary, incorporating elements of Perennial plant, Agronomy, Plant ecology and Chenopodiaceae. The Dry weight, Shoot and Transpiration research he does as part of his general Botany study is frequently linked to other disciplines of science, such as Extensin, therefore creating a link between diverse domains of science.

His Salinity research includes themes of Haloxylon and Atriplex. The various areas that Irwin A. Ungar examines in his Germination study include Puccinellia nuttalliana, Obligate, Salicornia europaea and Seedling. His research in Horticulture intersects with topics in Salinity stress and Soil salinity.

His most cited work include:

  • Halophyte seed germination (327 citations)
  • Ecophysiology of Vascular Halophytes (317 citations)
  • THE EFFECT OF SALINITY AND TEMPERATURE ON THE GERMINATION OF POLYMORPHIC SEEDS AND GROWTH OF ATRIPLEX TRIANGULARIS WILLD. (259 citations)

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

The scientist’s investigation covers issues in Botany, Halophyte, Salinity, Germination and Agronomy. His Botany research incorporates themes from Suaeda and Spergularia marina. His Salicornia europaea and Salicornia study in the realm of Halophyte connects with subjects such as Hordeum jubatum.

  • Salinity (58.20%)

What were the highlights of his more recent work (between 1996-2017)?

  • Botany (77.05%)
  • Salinity (58.20%)
  • Halophyte (62.30%)

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

His primary scientific interests are in Botany, Salinity, Halophyte, Germination and Horticulture. His Botany study is mostly concerned with Shoot, Dry weight, Osmotic pressure, Gibberellic acid and Perennial plant. His work carried out in the field of Salinity brings together such families of science as Atriplex, Chenopodiaceae and Salt marsh.

Irwin A. Ungar has researched Halophyte in several fields, including Haloxylon, Agronomy and Transpiration. His work on Dormancy and Seed dormancy as part of general Germination study is frequently linked to Distilled water, bridging the gap between disciplines. His work on Succulent plant and photoperiodism as part of general Horticulture research is often related to Temperature treatment and Bay, thus linking different fields of science.

Between 1996 and 2017, his most popular works were:

  • Effects of Salinity on Growth, Water Relations and Ion Accumulation of the Subtropical Perennial Halophyte, Atriplex griffithii var. stocksii (246 citations)
  • Effect of Salinity on Germination and Seedling Growth of two Atriplex species (Chenopodiaceae) (240 citations)
  • The effect of salinity on the growth, water status, and ion content of a leaf succulent perennial halophyte, Suaeda fruticosa (L.) Forssk (214 citations)

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

  • Botany
  • Ecology
  • Halophyte

His primary areas of investigation include Salinity, Halophyte, Botany, Horticulture and Germination. His Salinity research is multidisciplinary, incorporating perspectives in Atriplex, Perennial plant and Chenopodiaceae. His Halophyte study combines topics from a wide range of disciplines, such as Low marsh, Salt marsh, Agronomy and High marsh.

His Agronomy research integrates issues from Spergularia, Suaeda, Salicornia europaea and Spergularia marina. Botany and Suaeda fruticosa are commonly linked in his work. His study in the field of Succulent plant also crosses realms of Temperature treatment and Bay.
