Special Issue Information

Dear Colleagues,

Global ornamental production is in search of new, innovative trends and niches that will aid in an increase in product sales. In this Special Issue (SI), we aim to record the most recent and innovative practices in propagation, irrigation, fertilization, PGR application, substrate mixtures, plant protection, sustainable and eco-friendly production, biotechnology, postharvest handling, and quality of endemic plants. Scientific research on new species from the endemic flora, with a potential ornamental value, will contribute to the development of new products for the floriculture sector. Manuscripts for this SI may focus on, but not be limited to, the following eight major topics: (1) propagation (e.g., in-vitro, stem cuttings, seeds, and bulbs); (2) innovative cultivation practices and techniques (e.g., irrigation, fertilization, pest and disease management, environmental control, and PGR treatments); (3) sustainable and eco-friendly cultivation practices (e.g., CO2 footprint and life cycle assessments); (4) introduction of new species and varieties (i.e. taxonomy, molecular markers, genotype selection etc.); (5) biochemical profiles (e.g., antioxidant potential, volatile compounds, terpenes, and phenols); (6) postharvest handling and quality (e.g., postharvest treatments and packaging); (7) trade, sales, logistics, and the economic importance of new plant species and cut flowers; and (8) case studies in gardening.

Salvia tomentosa is a perennial sage of the maquis vegetation, strongly aromatic, with medicinal and ornamental value. Aiming to facilitate the promotion of the species in the floriculture sector, its micropropagation was studied in terms of the effect of explant origin and medium plant growth regulators on in vitro cultures establishment, shoot proliferation and rooting. Shoot tip or single node explants excised from either in vitro grown seedlings or greenhouse plants grown from cuttings of mature plants were cultured on MS medium supplemented with 6-benzyladenine (BA) at concentrations 0.0–3.2 mg L−1 in combination with 0.0, 0.01 and 0.1 mg L−1 1-naphthaleneacetic acid (NAA). Infections were the biggest problem for establishing cultures from greenhouse plants, while explants from in vitro seedlings showed hyperhydricity, especially the nodal ones. In the multiplication stage, high BA concentrations reduced explant response to produce shoots as well as the length of shoots produced, and although they increased shoot number per responding explant, a large number of shoots were hyperhydrated especially in explants of seedling origin. In general, the highest multiplication indexes, relevant to normal shoots, were given by the hormone-free medium or one with low BA concentration, and by shoot tip explants originated from greenhouse adult plants. The highest rooting rates (70–78%) were achieved either at full or half strength hormone-free or with 0.1 mg L−1 indole-3-butyric acid (IBA) medium. Increasing IBA resulted in an increase in root number, but a decrease in rooting rate and root length. Ex vitro acclimatization was highly successful (92–96%) in peat-perlite (1:1 v/v) substrate. The micropropagation protocol developed will contribute to the promotion of S. tomentosa in the floriculture and pharmaceutical industry and will be a tool for breeding programs targeting high value products.

The development of inter-row wildflower meadows in vineyards could restore and preserve biodiversity as well as enhance the local rural landscape character. Herein, the prospect of inter-row development of a wildflower meadow from spontaneous vegetation growing within a table grape ‘Sultanina’ vineyard was studied for two years through the effect of different intensities of harvest on the meadow composition, arthropod presence, and grape vine produce. Three harvest treatments (constant, periodic, and none) were examined. The growth (height and area of groundcover) and number of plants per species that composed the inter-row wildflower meadow as well as the insects found within it and on the grape vine plants were recorded. At maturity, the main quantitative (yield/vine) and qualitative characteristics (soluble solids, pH, and total titratable acidity) of the grapes were evaluated. Results showed that both the quantitative and qualitative characteristics of the grape vines did not differ between treatments. The inter-row vineyard meadow composition that constituted of 21 herbaceous species did not differ between the periodic- and no-harvest treatments. Insect pests hosted within the meadow did not pose a threat to ‘Sultanina’ grapes, although thrips within the inter-row meadow showed a preference for Convolvulus arvensis. The overall results suggest the application of either a periodic- or no-harvest on the spontaneous vegetation of a Mediterranean ‘Sultanina’ vineyard over two years and constitutes the development of inter-row wildflower meadows from spontaneous vegetations as an appealing and promising sustainable vineyard floor management practice for permanent use that needs to be further researched.

In the context of sustainable utilisation of valuable but neglected plant resources, a multifaceted study is presented herein for Greek native genotypes of elderberry (Sambucus nigra L., Caprifoliaceae), a species with an appreciated pharmaceutical and nutritional value. At the first phase, fresh plant materials (leaves, softwood cuttings) were collected from nine geographically separated genotypes originating from wild-growing Greek native germplasm of S. nigra. The leaf samples were genetically authenticated using DNA barcoding (ITS2). The next phase included the development of an asexual propagation protocol via cuttings which included screening of the collected genotypes in terms of propagation success, and further experimentation over a two-year period on a prioritised genotype. The propagation results highlighted the importance of external application of indole-3-butyric acid (IBA) rooting hormone at levels of 2000–4000 ppm, which consistently presented high rooting rates (100%) of summer softwood, leafy cuttings of apical or sub-apical type. At the same time, rooting quality in terms of root number and length as well as early plant growth after rooting, were improved by external hormone application resulting in high rates of plant survival. This study reports first-time data on multifaceted assessment of Greek native S. nigra genotypes on molecular authentication and asexual propagation, thus ultimately setting the basis for domestication and sustainable utilization of this species.

Wild phytogenetic resources are threatened by overexploitation. This pressure on species and natural ecosystems can be alleviated in part by recruiting and domesticating wild-growing species under pilot cultivation with tailor-made fertilization schemes. This study focused on the pilot cultivation of Origanum microphyllum—a critically endangered local endemic plant of Crete, Greece—investigating the effect of conventional and integrated nutrient management (ΙΝΜ) fertilizers by foliar or root application and biostimulant. Above-ground biomass together with leaf chlorophyll fluorescence and color (SPAD meter, DA meter, Chroma Meter) were determined. Leaf chlorophyll, antioxidant compound (carotenoids, phenols, flavonoids), and nutrient contents were also assessed. The results showed that fertilization did not significantly affect plant growth and leaf nutrient content. Root fertilization was associated with greener leaves compared to foliar. The same trend was generally evident for antioxidant compound content. The small size of leaves may have impeded the efficiency of the foliar application. In conclusion, root application of conventional or INM fertilizers seems more suitable to promote visual quality and herbal antioxidant profile of O. microphyllum, than the foliar one. Full article

Aiming to obtain Salvia hybrids with ornamental value and high drought resistance, for xeriscaping, crossbreeding was made with Greek Salvia species. S. fruticosa and S. officinalis when used as seed parent were successfully crossed with S. pomifera ssp. pomifera, S. ringens and S. tomentosa, while when used as pollen parent it only succeeded between S. fruticosa and S. tomentosa. The growth of S. fruticosa and the four hybrids, S. officinalis × S. pomifera, S. officinalis × S. tomentosa, S. officinalis × S. ringens and S. fruticosa × S. ringens, selected for their ornamental traits, was evaluated under limited irrigation and modification of the substrate with attapulgite clay. The hybrids S. officinalis × S. ringens and S. officinalis × S. tomentosa developed a compact plant shape and most lateral shoots, desirable characteristics for potted plants and xeriscaping. All hybrids, especially S. officinalis × S. pomifera and S. officinalis × S. tomentosa, survived water stress better than S. fruticosa. Modification of the substrate with attapulgite, under limited irrigation, caused a decrease in the above ground/root biomass ratio in some hybrids and in S. fruticosa increased the dry weight of the root indicating increased drought resistance.
