Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Horticulture

Paul Hadley focuses on Botany, Horticulture, Agronomy, Dry weight and Sowing. His work on Anthocyanin, Light effect and photoperiodism is typically connected to Somatic embryogenesis as part of general Botany study, connecting several disciplines of science. His studies in Horticulture integrate themes in fields like Biomass, Desiccation and Irradiance.

His research in Agronomy tackles topics such as Carbon dioxide which are related to areas like Granule, Amylose and Starch. He usually deals with Dry weight and limits it to topics linked to Anthesis and Winter wheat, Grain yield, Maturity and Animal science. His research investigates the connection with Sowing and areas like Crop which intersect with concerns in Biomass.

His most cited work include:

  • Effect of High Temperature Stress at Anthesis on Grain Yield and Biomass of Field-grown Crops of Wheat (286 citations)
  • The duration and rate of grain growth, and harvest index, of wheat (Triticum aestivum L.) in response to temperature and CO2 (184 citations)
  • Growth and yield of winter wheat (Triticum aestivum) crops in response to CO2 and temperature (173 citations)

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

Horticulture, Agronomy, Botany, Sowing and photoperiodism are his primary areas of study. His Horticulture research is multidisciplinary, relying on both Photosynthesis and Crop. His Agronomy study integrates concerns from other disciplines, such as Biomass and Plant physiology.

His Botany study combines topics in areas such as Light intensity and Juvenile. His Sowing research incorporates themes from Canopy and Environmental factor. His research investigates the link between Dry weight and topics such as Carbon dioxide that cross with problems in Poaceae.

He most often published in these fields:

  • Horticulture (40.25%)
  • Agronomy (30.82%)
  • Botany (28.93%)

What were the highlights of his more recent work (between 2011-2021)?

  • Horticulture (40.25%)
  • Agronomy (30.82%)
  • Theobroma (7.55%)

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

The scientist’s investigation covers issues in Horticulture, Agronomy, Theobroma, Dry season and Climate change. His Horticulture study frequently involves adjacent topics like Botany. In general Botany, his work in Photosynthesis is often linked to Limiting linking many areas of study.

His Agronomy study incorporates themes from Sedum, Evapotranspiration and Stomatal conductance. His research investigates the connection between Theobroma and topics such as Gliricidia sepium that intersect with issues in Water content, Organic fertilizer, Soil water, Fertilizer and Field experiment. His work carried out in the field of Climate change brings together such families of science as Agroforestry, Primary production and Seasonality.

Between 2011 and 2021, his most popular works were:

  • Low relative humidity triggers RNA-directed de novo DNA methylation and suppression of genes controlling stomatal development (101 citations)
  • Transgenerational, Dynamic Methylation of Stomata Genes in Response to Low Relative Humidity (41 citations)
  • Relative importance of transpiration rate and leaf morphological traits for the regulation of leaf temperature (34 citations)

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

  • Botany
  • Ecology
  • Agriculture

Paul Hadley mainly investigates Epigenetics, Arabidopsis, DNA methylation, Methylation and Genetics. His Epigenetics research entails a greater understanding of Gene. The Mutant, Gene silencing and Locus research Paul Hadley does as part of his general Gene study is frequently linked to other disciplines of science, such as Inheritance Patterns and Penetrance, therefore creating a link between diverse domains of science.

His Arabidopsis thaliana research is multidisciplinary, incorporating perspectives in Abiotic stress and Drought tolerance.
