Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Horticulture
  • Agriculture

The scientist’s investigation covers issues in Horticulture, Stomatal conductance, Irrigation, Evapotranspiration and Agronomy. Horticulture is closely attributed to Botany in his study. His Stomatal conductance research focuses on subjects like Anthesis, which are linked to Soil water.

His Irrigation research includes elements of Lysimeter and Growing season. His study in Lysimeter is interdisciplinary in nature, drawing from both Water use, Vine, Canopy and Crop coefficient. Many of his research projects under Agronomy are closely connected to Irrigation in viticulture with Irrigation in viticulture, tying the diverse disciplines of science together.

His most cited work include:

  • Biology of the grapevine. (553 citations)
  • Grapevine water use and the crop coefficient are linear functions of the shaded area measured beneath the canopy (221 citations)
  • Correlations among Predawn Leaf, Midday Leaf, and Midday Stem Water Potential and their Correlations with other Measures of Soil and Plant Water Status in Vitis vinifera (220 citations)

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

His primary areas of investigation include Horticulture, Agronomy, Irrigation, Botany and Evapotranspiration. His Horticulture research incorporates themes from Canopy and Stomatal conductance. His study in the field of Anthesis also crosses realms of Root nodule.

As part of his studies on Irrigation, Larry E. Williams frequently links adjacent subjects like Growing season. His Botany study incorporates themes from Cyanamide and Fumigation. Larry E. Williams has included themes like Veraison, Water use, Soil water, Lysimeter and Drip irrigation in his Evapotranspiration study.

He most often published in these fields:

  • Horticulture (59.77%)
  • Agronomy (34.48%)
  • Irrigation (33.33%)

What were the highlights of his more recent work (between 2015-2021)?

  • Horticulture (59.77%)
  • San Joaquin (5.75%)
  • Vine (19.54%)

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

His scientific interests lie mostly in Horticulture, San Joaquin, Vine, Growing season and Cultivar. His work deals with themes such as Cyanamide, Canopy and Irrigation, which intersect with Horticulture. His Irrigation study integrates concerns from other disciplines, such as Leaf water, Wine grape and Vitis vinifera.

While the research belongs to areas of San Joaquin, he spends his time largely on the problem of Crop coefficient, intersecting his research to questions surrounding Lysimeter. His Vine research is multidisciplinary, incorporating elements of Fresh weight, Berry and Crop evapotranspiration. In his study, Vineyard is inextricably linked to Stomatal conductance, which falls within the broad field of Evapotranspiration.

Between 2015 and 2021, his most popular works were:

  • A continuum of stomatal responses to water deficits among 17 wine grape cultivars (Vitis vinifera). (10 citations)
  • Dry Matter Accumulation and Nitrogen and Potassium Partitioning in the Roots and Trunk of Field-Grown Thompson Seedless Grapevines (4 citations)
  • Measured and estimated water use and crop coefficients of grapevines trained to overhead trellis systems in California’s San Joaquin Valley (4 citations)

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

  • Botany
  • Horticulture
  • Agriculture

His main research concerns Horticulture, Vine, Growing season, Irrigation and Remote sensing. In most of his Horticulture studies, his work intersects topics such as Crop coefficient. His Vine study combines topics from a wide range of disciplines, such as Shoot, Dry matter, Agronomy, Root system and Anthesis.

The study incorporates disciplines such as Canopy, San Joaquin, Lysimeter, Evapotranspiration and Trellis in addition to Growing season. His Irrigation research integrates issues from Cultivar, Wine grape, Stomatal conductance, Leaf water and Vitis vinifera. His Remote sensing research focuses on Multispectral image in particular.
