Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Gene
  • Biochemistry

The scientist’s investigation covers issues in Biochemistry, Botany, Horticulture, Agronomy and Abscisic acid. His work on Glutathione reductase, Catalase and Trehalose is typically connected to Osmoprotectant as part of general Biochemistry study, connecting several disciplines of science. His work on Pollen and Phaseolus as part of general Botany research is often related to Arsenic and Polluted soils, thus linking different fields of science.

His research in Pollen intersects with topics in Germination and Reproduction. His work in Horticulture is not limited to one particular discipline; it also encompasses Malondialdehyde. The Crop yield and Annual plant research he does as part of his general Agronomy study is frequently linked to other disciplines of science, such as Redox and Cellular homeostasis, therefore creating a link between diverse domains of science.

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

Agronomy, Horticulture, Botany, Pollen and Germination are his primary areas of study. His Agronomy research integrates issues from Photosynthesis and Abiotic component. Harsh Nayyar has researched Horticulture in several fields, including Malondialdehyde, Catalase and Stomatal conductance.

While the research belongs to areas of Catalase, he spends his time largely on the problem of Food science, intersecting his research to questions surrounding Superoxide dismutase, Glutathione reductase and Hydrogen peroxide. His Shoot study, which is part of a larger body of work in Botany, is frequently linked to Ascorbic acid, bridging the gap between disciplines. His research integrates issues of Sucrose-phosphate synthase and Annual plant in his study of Pollen.

He most often published in these fields:

  • Agronomy (38.71%)
  • Horticulture (34.68%)
  • Botany (27.42%)

What were the highlights of his more recent work (between 2018-2021)?

  • Horticulture (34.68%)
  • Abiotic stress (10.48%)
  • Pollen (18.55%)

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

Harsh Nayyar mainly investigates Horticulture, Abiotic stress, Pollen, Photosynthesis and Germination. His study in the field of Chlorophyll fluorescence is also linked to topics like Temperature stress. His Pollen study incorporates themes from Cultivar, Agronomy and Sterility.

His Agronomy research includes themes of Oxidative damage and Function. His Photosynthesis research is multidisciplinary, relying on both Chlorophyll, Nanomaterials, Carbon nanotube and Anatomy. His Germination research incorporates elements of Vascular tissue and Point of delivery.

Between 2018 and 2021, his most popular works were:

  • Drought and heat stress-related proteins: an update about their functional relevance in imparting stress tolerance in agricultural crops (31 citations)
  • Influence of drought and heat stress, applied independently or in combination during seed development, on qualitative and quantitative aspects of seeds of lentil (Lens culinaris Medikus) genotypes, differing in drought sensitivity. (26 citations)
  • GABA (γ-aminobutyric acid), as a thermo-protectant, to improve the reproductive function of heat-stressed mungbean plants (24 citations)

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

  • Botany
  • Gene
  • Ecology

Harsh Nayyar spends much of his time researching Horticulture, Germination, Osmolyte, Drought tolerance and Pollen. His Horticulture research incorporates themes from Starch, Microgametogenesis, Anther dehiscence, Tapetum and Sterility. The various areas that Harsh Nayyar examines in his Germination study include Photosynthesis, Chlorophyll fluorescence, Trehalose and Turgor pressure.

His Osmolyte study integrates concerns from other disciplines, such as Reactive oxygen species, Crop yield and Protein degradation. The concepts of his Pollen study are interwoven with issues in Genetic variability, Cultivar, Mediterranean climate and Point of delivery. Osmoprotectant is integrated with Abiotic component and Agronomy in his study.
