Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Enzyme
  • Horticulture

Rob R. Walker spends much of his time researching Horticulture, Salinity, Chloride, Shoot and Botany. Rob R. Walker studies Horticulture, focusing on Rootstock in particular. His Rootstock research incorporates themes from Yield and Pruning.

His research integrates issues of Photosynthesis, Sodium and Turgor pressure in his study of Chloride. Rob R. Walker mostly deals with Transpiration in his studies of Botany. His research investigates the connection with Transpiration and areas like Xylem which intersect with concerns in Trifoliate orange.

His most cited work include:

  • Citrus and salinity (245 citations)
  • Evapotranspiration components from energy balance, sapflow and microlysimetry techniques for an irrigated vineyard in inland Australia (134 citations)
  • An Analysis of Photosynthetic Response to Salt Treatment in Vitis vinifera (110 citations)

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

Horticulture, Rootstock, Salinity, Botany and Agronomy are his primary areas of study. His Horticulture research incorporates elements of Photosynthesis, Sodium, Irrigation and Chloride. His work carried out in the field of Rootstock brings together such families of science as Wine, Transpiration, Potassium, Shoot and Soil salinity.

His work on Saline water as part of general Salinity study is frequently connected to Mathematics and Sodium adsorption ratio, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. The various areas that Rob R. Walker examines in his Botany study include Invertase and Sucrose. His Agronomy research incorporates themes from Vineyard and Vine.

He most often published in these fields:

  • Horticulture (69.12%)
  • Rootstock (52.94%)
  • Salinity (32.35%)

What were the highlights of his more recent work (between 2016-2021)?

  • Horticulture (69.12%)
  • Rootstock (52.94%)
  • Chloride (22.79%)

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

His primary areas of study are Horticulture, Rootstock, Chloride, Salt and Sodium. Rob R. Walker works mostly in the field of Horticulture, limiting it down to concerns involving Wine and, occasionally, Saline water. His Rootstock study combines topics in areas such as Quantitative trait locus, Cultivar and Allele.

In his research on the topic of Chloride, Abiotic component is strongly related with Salinity. His studies deal with areas such as Abscisic acid, Botany and Transpiration as well as Sodium. Rob R. Walker combines subjects such as Composition, Anthocyanin and Irrigation with his study of Yield.

Between 2016 and 2021, his most popular works were:

  • Functional differences in transport properties of natural HKT1;1 variants influence shoot Na+ exclusion in grapevine rootstocks. (31 citations)
  • Fast Phenomics in Vineyards: Development of GRover, the Grapevine Rover, and LiDAR for Assessing Grapevine Traits in the Field. (11 citations)
  • Effect of water deficits and season on berry development and composition of Cabernet Sauvignon (Vitis vinifera L.) grown in a hot climate (11 citations)

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

  • Botany
  • Enzyme
  • Horticulture

The scientist’s investigation covers issues in Shoot, Deficit irrigation, Locus, Allele and Quantitative trait locus. His Shoot study is concerned with the larger field of Botany. The study of Botany is intertwined with the study of Chloride in a number of ways.

Salinity, Abscisic acid, Transpiration, Sodium and Stomatal conductance are fields of study that overlap with his Deficit irrigation research. His Locus study frequently links to other fields, such as Gene expression. His Allele research is multidisciplinary, relying on both Rootstock, Hybrid, Transmembrane domain and Candidate gene.
