“…Flowering periodicity, productivity, and market quality do not depend exclusively on thermal stimuli; additional criteria are necessary to promote anthesis signalling pathways. These criteria include age, bulb size, and weight, all affecting the flowering capability, with critical parameters differing between taxa, species, and cultivars [23,31,36]. The dynamic metabolic processes associated with shoot apical meristematic transition activity during bulb dormancy necessitate energy, water transfer and delivery.…”

“…Storage temperatures up to 25 • C promoted healthy vegetative development, inflorescence maturity and flower bud opening in Watsonia corms [35]. Storage significantly impacted the flower diameter and number of days before flowering in Hippeastrum [36] and accelerated flowering in Eucomis species [37]. Other Amaryllidaceae genera that flourish in hot, dry summer areas and respond to warm storage techniques include Narcissus species, Nerine flexuosa, and N. sarniensis [38].…”

Amaryllis belladonna is an autumn-flowering bulbous geophyte endemic to the Western Cape, South Africa. The species’ erratic flowering disposition and brief flowering period upon maturity limit its economic productivity and competitiveness within the traditional genera of cut flowers and potted plants. However, it can be an attractive, eco-friendly, seasonal addition to the specialty floriculture market. A 10-month study evaluated the effects of a warm storage period on A. belladonna bulbs’ flowering yield, flowering time, quality characteristics, and foliage growth. The experiment comprised dormant flower-sized bulbs randomly assigned to one of six storage regimes of either a 0- (no storage control), 4-, 6-, 8-, 10-, or 12-week interval periods at a continuous warm temperature of 23 ± 1 °C before planting into pots between mid-November 2021 and mid-February 2022 in the greenhouse. The results showed that flowering production (64.3% flowering after the 12-week storage), flowering time (anthesis occurring 9 days after the 10- and 12-week storage), and quality attributes (number of florets in the inflorescence, scape diameter, inflorescence fullness ratio, and pot longevity) of A. belladonna scapes were significantly impacted by warm bulb storage, but not foliage growth. Irrespective of bulb storage, inflorescence abortion occurred. An extended bulb storage did not advance the flowering time despite a greater harvest and shorter cultivation periods after planting. This study established that a cumulative temperature range during bulb dormancy is crucial for supporting the A. belladonna inflorescence maturity’s energetic demands and the opening of floret buds. Bulbs should be stored at elevated temperatures for at least 8–10 weeks to attain the best floret-quality attributes and longevity. However, for an economical and sustainable greenhouse and specialty cut flower production, 12-week warm bulb storage is recommended to achieve the optimal anthesis in the shortest interval for this seasonal single-harvest species after planting.

In this study, we investigated the photosystem II photochemical efficiency (variable to maximum fluorescence ratio, F v /F m ), vegetative growth, and productivity of radish (Raphanus sativus var. hortensis) grown under different day/night temperatures (14/8°C, 19/13°C, 24/18°C, 29/23°C, and 34/28°C). Radish seed germination rates corresponding to Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) stage 09 occurred readily at temperatures higher than 24/18°C, whereas hypocotyls elongated rapidly to cause abnormal root curving above 29/23°C. Shoots and roots grew well at 30 days after sowing (DAS). Leaves developed rapidly at temperatures above 24/18°C, reaching BBCH stage 19 at 30 DAS, during which leaf number and area increased, whereas roots showed better development at temperatures below 24/18°C, taking ~70 days for 70% of roots to attain BBCH stage 47 at 24/18°C. Root growth rates were highest at 24/18°C, with root diameters reaching ≥ 10 cm within 80 DAS at 24/18°C. At 85 DAS, high-quality roots, i.e., thick and long with no internal browning, were produced at 24/18°C. F v /F m was high at temperatures below 24/18°C, and absorption flux per cross-section (ABS/CS m ), trapped energy flux per cross section (TR o /CS m ), and electron transport per cross section (ET o /CS m ) were high at 19/13°C and 24/18°C. These findings indicate that radish plants grew well and without temperature stress at 19/13°C and 24/18°C. However, the optimal day/night temperature for producing high-quality radish roots of marketable size and weight is 24/18°C.

Background Cultivated Hippeastrum × hybridum is a popular ornamental plant with large and colorful flowers, long flowering duration, and high commercial value. As its main ornamental feature, its flower color is related to the anthocyanin content in the tepals. However, the molecular regulatory mechanisms of anthocyanin biosynthesis in H. × hybridum have not yet been elucidated. Results In the present study, 12 cDNA libraries of four stages of H.× hybridum ‘Royal Velvet’ tepal development were used for RNA-seq, obtaining 79.83 gigabases (GB) of clean data. The data were assembled into 148,453 unigenes, and 11,262 differentially expressed genes were identified. Forty key enzymes participating in anthocyanin biosynthesis were investigated, and the results showed that most of the anthocyanin structural genes were expressed at low levels in S1 and were markedly upregulated in S2 and S3. The expression profiles of 12 selected genes were verified by qRT-PCR. Furthermore, the R2R3-MYB transcription factor (TF), HpMYB1, involved in the regulation of anthocyanin biosynthesis was identified by sequence, expression pattern, and subcellular localization analyses. Its overexpression in tobacco significantly increased the anthocyanin levels in various tissues and activated anthocyanin-related genes. Conclusions Using RNA-seq technology, we successfully identified a potential R2R3-MYB gene, HpMYB1, that regulates anthocyanin biosynthesis in H.× hybridum ‘Royal Velvet’. Our findings provide basic transcript information and valuable transcriptome data for further identification of key genes involved in anthocyanin biosynthesis and can be applied in the artificial breeding of new H. × hybridum cultivars with enhanced ornamental value.
