Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Horticulture
  • Photosynthesis

His scientific interests lie mostly in Agronomy, Veraison, Horticulture, Ripening and Transpiration. His Agronomy study combines topics from a wide range of disciplines, such as Rootstock and Canopy. His biological study deals with issues like Shoot, which deal with fields such as Irrigation.

His Horticulture study focuses on Cultivar in particular. Markus Keller works mostly in the field of Ripening, limiting it down to topics relating to Berry and, in certain cases, Compensation point. His Transpiration research focuses on Xylem and how it relates to Root pressure.

His most cited work include:

  • The Science of Grapevines: Anatomy and Physiology (234 citations)
  • Managing grapevines to optimise fruit development in a challenging environment: a climate change primer for viticulturists (208 citations)
  • Deficit Irrigation and Vine Mineral Nutrition (144 citations)

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

The scientist’s investigation covers issues in Horticulture, Botany, Berry, Ripening and Xylem. In his research on the topic of Horticulture, Canopy is strongly related with Agronomy. His Berry research incorporates themes from Rootstock, Anthocyanin, Wine, Titratable acid and Sugar.

The Ripening study combines topics in areas such as Compensation point, Osmotic pressure and Brix. His Xylem research is multidisciplinary, incorporating elements of Phloem and Transpiration, Root pressure. His studies examine the connections between Yield and genetics, as well as such issues in Vine, with regards to Pruning.

He most often published in these fields:

  • Horticulture (55.14%)
  • Botany (30.84%)
  • Berry (28.04%)

What were the highlights of his more recent work (between 2017-2021)?

  • Horticulture (55.14%)
  • Vitis vinifera (10.28%)
  • Berry (28.04%)

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

Markus Keller mostly deals with Horticulture, Vitis vinifera, Berry, Cultivar and Vineyard. He combines subjects such as Vascular tissue, Phenology and Acclimatization with his study of Horticulture. Berry is closely attributed to Ripening in his study.

His study looks at the intersection of Vineyard and topics like Canopy with Crop, Pruning, Vine and Yield. Markus Keller works mostly in the field of Shoot, limiting it down to concerns involving Xylem and, occasionally, Liana. The concepts of his Sugar study are interwoven with issues in Wine, Anthocyanin, Titratable acid and Veraison.

Between 2017 and 2021, his most popular works were:

  • Grapevine leafroll disease alters leaf physiology but has little effect on plant cold hardiness (9 citations)
  • Interactive effects of high temperature and water deficit on Malbec grapevines (8 citations)
  • Spatial suitability assessment for vineyard site selection based on fuzzy logic (8 citations)

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

  • Botany
  • Horticulture
  • Photosynthesis

His primary scientific interests are in Horticulture, Cultivar, Stomatal conductance, Photosynthesis and Vitis vinifera. His Horticulture study frequently draws connections between related disciplines such as Transpiration. His biological study spans a wide range of topics, including photoperiodism, Bud growth and Phenology.

Markus Keller interconnects Vascular tissue, Cold acclimation, Growing season and Cane in the investigation of issues within Stomatal conductance. His research in Photosynthesis intersects with topics in Sugar, Vegetative reproduction and Greenhouse. His studies deal with areas such as Hardiness, Acclimatization, Crop yield and Temperate climate as well as Vitis vinifera.
