The Role of Plant Growth Regulators in Horticulture

Dear Colleagues,

The Special Issue on "The Role of Plant Growth Regulators in Horticulture" delves into the intricate mechanisms by which plant growth regulators (PGRs) control the growth, development, and physiological processes of horticultural plants. PGRs, including hormones such as auxins, gibberellins, cytokinins, abscisic acid, and ethylene, play pivotal roles in regulating various aspects of plant growth and development, ranging from seed germination to fruit ripening.

This Special Issue provides a comprehensive platform for researchers, scientists, and practitioners to explore the multifaceted functions of PGRs in horticulture and their implications for crop improvement, yield optimization, and quality enhancement. Contributions cover a wide spectrum of topics, including the following:

1. Molecular mechanisms underlying the biosynthesis, signal transduction, and action of PGRs in horticultural plants.
2. The regulation of plant morphogenesis, including shoot and root growth, branching, and flowering, by PGRs.
3. Interactions between PGRs and environmental factors, such as light, temperature, and water availability, in shaping plant growth and development.
4. The applications of PGRs in horticultural practices, including plant tissue culture, crop production, propagation, and postharvest management.
5. The development and optimization of PGR-based strategies for crop protection, stress mitigation, and abiotic stress tolerance in horticultural plants.
6. Novel approaches and technologies for the synthesis, formulation, and delivery of PGRs to improve their efficacy and sustainability in horticultural systems.

By elucidating the intricate roles of PGRs in horticultural plant physiology and development, this Special Issue aims to advance our understanding of fundamental plant biology principles and practical applications in horticulture. Through interdisciplinary collaboration and knowledge exchange, researchers and practitioners can harness the potential of PGRs to optimize crop performance, enhance yield and quality, and promote sustainable practices in horticultural production systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Horticulturae is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
