Special Issue Information

Dear Colleagues,

Many environmental pressures are applied to plants that lower and restrict the yield and quality of crops, which is much more severe for ornamental plants for their marketability. Ornamental plants experience various environmental stresses naturally and artificially in the production process.  

Drought, salt, extremely high or low temperatures (cold or heat), and light oxidative stress are representative abiotic stressors that frequently interact and cause cellular and functional damage. It is common for plants to experience abiotic stresses in the production environment, even in environmentally controlled greenhouses. This state causes complicated reactions in plants, reduces crop output, and is getting worse due to climate change. The ability of a plant to compartmentalize ions, create suitable solutes, synthesize particular proteins and metabolites, and trigger transcriptional factors are all associated with the process of tolerance.

This Special Issue prioritizes morphological, physiological, and molecular insights into plant tolerance responses to abiotic stress.

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.

This study investigates the phenotypic diversity of spring-flowering Crocus species native to Serbia by analyzing their morphological traits and flower color variations. Detailed phenotypic characterization was performed on seven species: C. alexandri, C. chrysanthus, C. heuffelianus, C. randjeloviciorum, C. rujanensis, C. variegatus, and C. weldenii. The study examines how morphological parameters of tested species diverged from average values during a hot and dry winter, resulting in smaller plants, earlier and shorter flowering periods, and reduced flower size, regardless of species. Hierarchical clustering based on morphological traits grouped the species into three clusters: the first cluster included C. alexandri, C. chrysanthus, C. rujanensis, and C. weldenii, characterized by the highest number of leaves and the lowest number of flowers; the second consisted of C. randjeloviciorum, distinguished by shorter plant height and the greatest number of flowers; and the third cluster comprised C. heuffelianus and C. variegatus, notable for the tallest plants, widest corms and leaves, and longest perigon segments. Grouping based on petal color components (L*, a*, b*, chroma, and hue) formed five distinct clusters, demonstrating differences in flower color. These findings are valuable for taxonomic classification, conservation measures, and breeding programs, which ultimately support the conservation of biodiversity and the promotion of ornamental plant cultivation. Flower color in particular has proven to be a reliable species indicator, as it remains constant despite the year and/or habitat. The use of a colorimeter can speed up the identification of species in the field and provides researchers and conservationists with a practical tool. Full article
