Research.com Recognitions

  • 2026 - Research.com Plant Science and Agronomy in Norway Leader Award
  • 2025 - Research.com Plant Science and Agronomy in Norway Leader Award

Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Horticulture

Olavi Junttila mostly deals with Botany, photoperiodism, Horticulture, Ecotype and Dormancy. Botany is closely attributed to Abscisic acid in his study. The study incorporates disciplines such as Gibberellin, Salix pentandra, Cold acclimation and Ecology in addition to photoperiodism.

His Horticulture research is multidisciplinary, relying on both Photosynthesis and Bilberry. His work in Ecotype tackles topics such as Hardiness which are related to areas like Climatic adaptation. Olavi Junttila has researched Dormancy in several fields, including Water stress, Meristem and Embryo.

His most cited work include:

  • Cold-Induced Freezing Tolerance in Arabidopsis (381 citations)
  • The dynamic nature of bud dormancy in trees: environmental control and molecular mechanisms. (327 citations)
  • Ectopic expression of oat phytochrome A in hybrid aspen changes critical daylength for growth and prevents cold acclimatization (258 citations)

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

His main research concerns Botany, photoperiodism, Horticulture, Gibberellin and Shoot. While the research belongs to areas of Botany, he spends his time largely on the problem of Abscisic acid, intersecting his research to questions surrounding Betulaceae. His photoperiodism study incorporates themes from Metabolite, Picea abies, Phytotron and Plant physiology.

In his study, Chlorophyll is strongly linked to Photosynthesis, which falls under the umbrella field of Horticulture. He works mostly in the field of Gibberellin, limiting it down to topics relating to Plant stem and, in certain cases, Pisum, as a part of the same area of interest. His study focuses on the intersection of Ecotype and fields such as Betula pendula with connections in the field of Climatic adaptation.

He most often published in these fields:

  • Botany (84.21%)
  • photoperiodism (44.08%)
  • Horticulture (36.84%)

What were the highlights of his more recent work (between 2005-2015)?

  • Botany (84.21%)
  • Horticulture (36.84%)
  • photoperiodism (44.08%)

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

Olavi Junttila spends much of his time researching Botany, Horticulture, photoperiodism, Dormancy and Agronomy. Botany and Northern latitude are two areas of study in which he engages in interdisciplinary research. The Horticulture study combines topics in areas such as Photosynthesis and Vaccinium myrtillus.

His research integrates issues of Gibberellin, Dry weight, Specific leaf area and Photosynthetic capacity in his study of photoperiodism. His studies in Dormancy integrate themes in fields like Ecology and Phenology. The various areas that Olavi Junttila examines in his Agronomy study include Axillary bud and Crown.

Between 2005 and 2015, his most popular works were:

  • The dynamic nature of bud dormancy in trees: environmental control and molecular mechanisms. (327 citations)
  • Climatic control of bud burst in young seedlings of nine provenances of Norway spruce. (84 citations)
  • Effects of temperature and photoperiod on yield and chemical composition of northern and southern clones of bilberry (Vaccinium myrtillus L.). (60 citations)

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

  • Botany
  • Ecology
  • Gene

The scientist’s investigation covers issues in Botany, photoperiodism, Picea abies, Dormancy and cDNA library. His work on Botany is being expanded to include thematically relevant topics such as Horticulture. His Horticulture research incorporates elements of Quinic acid and Bilberry.

His photoperiodism study frequently draws parallels with other fields, such as Gibberellin. His research in Dormancy intersects with topics in Ecology and Indeterminate growth. The concepts of his cDNA library study are interwoven with issues in Transcriptome and Candidate gene.
