Overview

What is he best known for?

The fields of study he is best known for:

Botany
Ecology
Enzyme

The scientist’s investigation covers issues in Botany, Phytotoxicity, Agronomy, Allelopathy and Weed. His study in Essential oil and Photosynthesis falls under the purview of Botany. His biological study spans a wide range of topics, including Eucalyptus and Myrtaceae.

His Phytotoxicity study combines topics in areas such as Bioherbicide, Dry weight and Citronellal. His study on Dry weight also encompasses disciplines like

Plant physiology that intertwine with fields like Oxidative stress and Antioxidant,
Lipid peroxidation most often made with reference to Glutathione,
Food science which intersects with area such as Malondialdehyde. Harminder Pal Singh combines subjects such as Parthenium and Shoot with his study of Parthenium hysterophorus.

His most cited work include:

Eucalyptus essential oil as a natural pesticide (513 citations)

Horticulture (15.64%)
Shoot (13.97%)

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

Harminder Pal Singh mainly investigates Internal medicine, Horticulture, Shoot, Inflammatory bowel disease and Gastroenterology. His Horticulture research is multidisciplinary, incorporating perspectives in Essential oil, Antioxidant and Oryza sativa. His Essential oil study integrates concerns from other disciplines, such as Avena fatua and Wilting.

Harminder Pal Singh does research in Antioxidant, focusing on Superoxide dismutase specifically. Harminder Pal Singh interconnects Peroxidase, Transpiration, Cultivar and Seedling in the investigation of issues within Shoot. The Phytotoxicity study combines topics in areas such as Asteraceae, Crop, Nuclear chemistry, Allelopathy and Reactive oxygen species.

Between 2018 and 2021, his most popular works were:

AGA Clinical Practice Guidelines on the Management of Moderate to Severe Ulcerative Colitis. (40 citations)
Chemical profiling, cytotoxicity and phytotoxicity of foliar volatiles of Hyptis suaveolens. (16 citations)
Insights into the tolerance and phytoremediation potential of Coronopus didymus L. (Sm) grown under zinc stress (14 citations)

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

Botany
Ecology
Enzyme

Horticulture, Essential oil, Shoot, Oryza sativa and Cultivar are his primary areas of study. The study incorporates disciplines such as Coleoptile, Malondialdehyde, Superoxide dismutase, Antioxidant and Piperitone in addition to Horticulture. His Superoxide dismutase study incorporates themes from Lipid peroxidation, Alkali soil, Red rice and Catalase.

His Antioxidant research is mostly focused on the topic Glutathione reductase. His work carried out in the field of Essential oil brings together such families of science as Avena fatua, Germination, Wilting, Echinochloa and Phytotoxicity. As a member of one scientific family, Harminder Pal Singh mostly works in the field of Oryza sativa, focusing on Panicle and, on occasion, Transplantation, Seedling, Upland rice and Anthocyanin.
