Special Issue Information

Dear Colleagues,

Ornamental plant cultivation and breeding is one of the most advanced cultivation methods in horticulture, which is spread worldwide and represents a significant economic income. Furthermore, ornamental plants are used in different shapes and forms, like indoor (cut flowers, potted houseplants) and outdoor plants (bedding flowers, ornamental shrubs and trees). In recent years, an increased demand for ornamental plants had been recorded on the market, and, because of this, horticulturists are working on the intensive cultivation, propagation, and breeding of new hybrids. Cultivating and breeding new varieties can be sometimes quite a challenging fact for horticulturists, since a lot of information about them is unclear and, most importantly, they need to cope with climate change, the rising demand for plants that can withstand urban environments, extreme weather conditions, or even water scarcity, and in addition to all of this, their most important attribute is to decorate the place where they are used. Therefore, horticulturists are constantly researching and experimenting to develop plants that are visually appealing and resilient to various environmental stressors. Additionally, collaborations with botanists and geneticists have become increasingly important in creating new hybrids that meet the demands of modern landscaping and gardening practices.

The present Special Issue aims to present advanced studies on new methods and innovations of cultivating, propagating, and breeding ornamentals plants and their uses in landscaping design.

We welcome original and review articles for this Special Issue.

We look forward to receiving your contributions.

Effects of Soil–Sand Mixtures on Alchemilla mollis and Geranium psilostemon: A Multi-Criteria Performance Analysis Under Low-Altitude Conditions Using PROMETHEE

The selection of suitable growing media plays a vital role in the successful adaptation of high-altitude plant species to lowland urban landscapes. This study assessed the morphological and physiological performance of two native perennial species, Alchemilla mollis and Geranium psilostemon, under low-altitude conditions using three different soil–sand (mil) mixtures: TA (50% soil–50% sand), TB (75% soil–25% sand), and TC (100% soil). Over a 17-month period, key plant growth parameters—including height, canopy diameter, leaf number, and chlorophyll concentration—were systematically monitored. Additionally, soil samples were analyzed before and after cultivation to determine pH, total nitrogen, organic matter, organic carbon, phosphorus, and electrical conductivity levels. To evaluate overall performance, the PROMETHEE multi-criteria decision-making (MCDM) method was applied, incorporating 11 criteria spanning plant development, soil quality, and economic considerations. Results revealed that the TC medium offered the most favorable outcomes for both species, particularly in terms of chlorophyll content and biomass accumulation. Conversely, the TB medium supported higher retention of nitrogen and organic matter. While A. mollis exhibited greater resilience under suboptimal conditions, G. psilostemon demonstrated rapid development under favorable settings. These findings underscore the potential of native perennial species in sustainable landscape design and validate the use of MCDM approaches in optimizing plant–soil interactions in horticultural applications.

Sapindus delavayi is a drought-resistant tree species endemic to the dry–hot valleys of Southwestern China and is of great significance for soil and water conservation and ecological restoration. In this study, we sequenced the transcriptome of its leaves using the Illumina HiSeq 4000 platform and obtained 96.12 Gb of high-quality data (Q20 = 98.68%, Q30 = 95.62%), which were de novo assembled to obtain 89,228 unigenes (N50 = 1538 bp), of which 63,005 (70.61%) were successfully annotated to at least one database (NR, NT, SwissProt, KOG, KEGG, GO, Pfam). Overall, 53.96% of the unigenes in the S. delavayi leaves were annotated to Acer yangbiense, which belongs to the same family as S. delavayi. A total of 42,870 CDSs and 21,488 SSR loci were detected, with the highest mononucleotide repeat rate at 42.72% of the total number. Drought stress experiments identified 669–1203 differentially expressed genes (DEGs). Through our research, the first high-quality transcriptome database of S. delavayi has been constructed and its drought-resistance-related gene features have been analyzed, laying an important foundation for future functional gene mining, molecular marker development, molecular diversity studies, molecular breeding, and ecological adaptation research.

Understory flowering plants often face limitations in pollinator availability. This necessitates an investigation of pollination mechanisms and reproductive traits to understand their survival strategies. Floral syndromes, which are critical determinants of plant–pollinator coevolution, significantly impact the reproductive success and diversification dynamics of angiosperms. The genus Impatiens is known for its remarkable floral diversity and varied pollination systems and it is also serves as an exemplary model for examining plant–pollinator interactions. Therefore, this study was performed to elucidate the pollination characteristics and breeding systems of three sympatric species, Impatiens davidii, Impatiens jinggangensis, and Impatiens commelinoides. The results indicated all the Impatiens species exhibited similar individual flower longevity (4–5 days). However, I. commelinoides and I. jinggangensis peaked in July-August, whereas I. davidii primarily flowered in August-September. These species shared a self-compatible breeding system that requires pollinators for facultative outcrossing, with bumblebees (Bombus) and polyester bees (Amegilla) identified as the primary pollinators. The presence of wing petals had a significant impact on fruit set in both I. davidii and I. commelinoides. The three Impatiens species demonstrated notable interspecific differences in their floral scent profiles, accompanied by distinct variations in floral morphology and scent characteristics. These differences collectively represent pollination strategies and life-history tactics that highlight pronounced interspecific divergence. The variation in pollination strategies is attributed to the synergistic interaction between floral morphology and scent chemistry. Thus, these findings offer valuable insights for the investigation of forest understory plant conservation, resource utilization, and co-evolutionary relationships with primary pollinators.
