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.

The tree peony holds significant historical, cultural, and practical value. P. ostii is extensively cultivated in China, where it represents the primary oil-producing variety of tree peonies. However, the current nutrient supplementation system for P. ostii lacks an empirical basis, resulting in frequent wastage of nutrients during daily production. In this study, varying ratios and quantities of nitrogen, phosphorus, and potassium were administered to P. ostii at distinct phases of its annual growth cycle, specifically during the bud sprouting, post-flowering, and dormancy periods. The results showed that during the bud sprouting period, the plants treated with a high nitrogen and potassium ratio (a high N&K ratio, N–P–K = 35%–20%–35%) had better flowering traits than those treated with a high phosphorus ratio (a high P ratio, N–P–K = 20%–35%–20%). Under the standard application amount, plants treated with a high N&K ratio outperformed those treated with a high P ratio in terms of flowering duration, net photosynthetic rate, and flowering biomass, with increases of 20.9%, 10.7%, and 32.9%, respectively. During the post-flowering period, all plants died when treated with 1.5 × standard amounts of the above ratios. At this period, the all-high ratio with N–P–K = 45%–45%–45% resulted in a 70.4% increase in fruit set, a 43.8% increase in seed number, and a 153.8% increase in biomass compared with the high N&K ratio. During the dormancy period, nutrient supplementation with the standard amount of P led to higher increases in ground diameter and biomass. Therefore, in subsequent tree peony production, particular attention should be paid to nutrient supplementation during the post-flowering period to prevent excessive fertilizer application and safeguard the plants’ normal growth and development.

Ornamental plant growing is carried out in relatively small areas compared to other agricultural production areas, but the use of basic inputs such as water and fertilizer is intensive. Quality in cyclamen and for other similar ornamental plants is related to the amount and quality of the flowers. Irrigation and fertilization are very effective applications of these parameters. This study was conducted in Türkiye to detect the effects of different irrigation programs and nitrogen doses on Cyclamen persicum Mill. in 2023–2024. There were 12 treatments in total. Three different irrigation programs were used. When 20% (I1), 40% (I2), and 60% (I3) of the available water holding capacity (AWHC) in the mixed soil were used, the irrigation water was applied in each irrigation until the available soil water reached the field capacity. There were four nitrogen doses for each irrigation program: N0: 0, N1: 10 kg N da−1, N2: 20 kg N da−1, and N3: 30 kg N da−1. All the parameters were affected negatively by water stress. The 20 kg da−1 nitrogen doses increased the number of flowers. Increasing water stress levels negatively affected the Pn. The zero nitrogen dose treatments (N0) provided the lowest average Pn with 7.53 μmol m−2 s−1. The I1 (frequency irrigation) irrigation program and N3 nitrogen dose can be applied together to obtain the best vegetative growth. As another option to obtain the most generative growth, the I1 (frequency irrigation) irrigation program and the N2 nitrogen dose can be applied together. Full article

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
