Overview

What is she best known for?

The fields of study she is best known for:

  • Botany
  • Horticulture
  • Irrigation

Her scientific interests lie mostly in Irrigation, Deficit irrigation, Agronomy, Horticulture and Mathematics. Her work carried out in the field of Irrigation brings together such families of science as Vineyard and Ripening, Botany, Olea. Joan Girona usually deals with Botany and limits it to topics linked to Soil water and Leaf water.

The concepts of her Deficit irrigation study are interwoven with issues in DNS root zone and Olive trees. In general Agronomy, her work in Crop, Cultivar and Water conservation is often linked to Composition linking many areas of study. Her work on Vegetative reproduction, Prunus and Fruit development as part of general Horticulture study is frequently linked to Chemistry, bridging the gap between disciplines.

Her most cited work include:

  • Mapping crop water stress index in a ‘Pinot-noir’ vineyard: comparing ground measurements with thermal remote sensing imagery from an unmanned aerial vehicle (182 citations)
  • The use of midday leaf water potential for scheduling deficit irrigation in vineyards (156 citations)
  • Sensitivity of Continuous and Discrete Plant and Soil Water Status Monitoring in Peach Trees Subjected to Deficit Irrigation (147 citations)

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

Her primary areas of investigation include Irrigation, Horticulture, Deficit irrigation, Agronomy and Botany. Her Irrigation study combines topics in areas such as Canopy, Yield and Crop. Her research in the fields of PEAR, Prunus and Fruit development overlaps with other disciplines such as Stage ii.

She has included themes like Cultivar, Postharvest, Soil water, Irrigation scheduling and Evapotranspiration in her Deficit irrigation study. Her studies in Agronomy integrate themes in fields like Fruit tree and Titratable acid. Her work in the fields of Leaf water, Pruning and Trunk overlaps with other areas such as Tree and Chemistry.

She most often published in these fields:

  • Irrigation (73.26%)
  • Horticulture (58.14%)
  • Deficit irrigation (50.00%)

What were the highlights of her more recent work (between 2013-2020)?

  • Irrigation (73.26%)
  • Horticulture (58.14%)
  • Canopy (17.44%)

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

Joan Girona focuses on Irrigation, Horticulture, Canopy, Phenology and Deficit irrigation. She does research in Irrigation, focusing on Crop water stress index specifically. Horticulture and Mathematics are two areas of study in which Joan Girona engages in interdisciplinary work.

She has researched Canopy in several fields, including Lysimeter, Agronomy, Crop coefficient and Transpiration. Her research in Phenology intersects with topics in Ripening, Growing season and Vitis vinifera. As part of one scientific family, Joan Girona deals mainly with the area of Yield, narrowing it down to issues related to the Titratable acid, and often Dry matter.

Between 2013 and 2020, her most popular works were:

  • Mapping crop water stress index in a ‘Pinot-noir’ vineyard: comparing ground measurements with thermal remote sensing imagery from an unmanned aerial vehicle (182 citations)
  • Seasonal evolution of crop water stress index in grapevine varieties determined with high-resolution remote sensing thermal imagery (59 citations)
  • Airborne Thermal Imagery to Detect the Seasonal Evolution of Crop Water Status in Peach, Nectarine and Saturn Peach Orchards (47 citations)

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

  • Botany
  • Horticulture
  • Irrigation

Her main research concerns Irrigation, Canopy, Spatial variability, Vineyard and Irrigation scheduling. Her Irrigation research is multidisciplinary, incorporating elements of Fruit tree, Horticulture, Lysimeter and Phenology. Joan Girona specializes in Horticulture, namely Postharvest.

Her Lysimeter research integrates issues from Botany, PEAR, Crop coefficient and Transpiration. Her study in Vineyard is interdisciplinary in nature, drawing from both Water stress and Crop water stress index. Her research investigates the connection with Irrigation scheduling and areas like Agricultural engineering which intersect with concerns in Water balance, Deficit irrigation and Irrigation in viticulture.
