Special Issue Information

Dear Colleagues,

The technology behind the production of horticultural crops in general and specifically vegetables, tuberous plants, herbs, and aromatic and medicinal plants, is of high interest due to these plants’ high economic and dietary value, their widespread cultivation and consumption across the globe, and the current challenges that they are facing due to climate change. In the development and application of modern cropping technologies, a deeper understanding of the physiology of the abovementioned crops and a more precise determination of their reaction to changing growth conditions are necessary. Modern technologies and cultivation techniques such as precision farming, smart and sustainable ΑΙ applications, and the use of beneficial microbial endophytes, hormones, biostimulants, and nanomaterials in both field and undercover cropping systems, as well as the use of artificial lighting in controlled horticulture (from greenhouses to vertical farming) significantly affect the production of propagating materials (e.g., in vitro propagation, transplant production, grafting), the development of plants, and the yield and quality of products. Technologies should therefore consider factors that influence plant physiology and, by extension, cultivation techniques, such as abiotic stress and the management of fertilization and irrigation water, with the ultimate aim of limiting cultivation inputs and enhancing sustainable production.

Chrysanthemum (Chrysanthemum morifolium Ramat.), a typical short-day plant (SDP), relies on photoperiod and light quality signals to regulate flowering and growth. Red light interruptions inhibit its flowering, whereas supplemental blue light can counteract this inhibitory effect. To investigate how “high-blue/low-red” mixed light (RBL) regulates chrysanthemum flowering and growth, we treated ‘Gaya Glory’ plants with 4 h of supplemental or night-interruptional RBL (S-RBL4 or NI-RBL4, 0 or 30 ± 3 μmol m−2 s−1 PPFD) under 10 h short-day and 13 h long-day conditions (SD10 and LD13; white light, WL; 300 ± 5 μmol m−2 s−1 PPFD), recorded as SD10, SD10 + S-RBL4, SD10 + NI-RBL4, LD13, LD13 + S-RBL4, and LD13 + NI-RBL4, respectively. Under SD10 conditions, S-RBL4 promoted flowering and enhanced nutritional quality, whereas NI-RBL4 suppressed flowering. Under LD13 conditions, both treatments alleviated flowering inhibition, with S-RBL4 exhibiting a more pronounced inductive effect. Chrysanthemums displayed superior vegetative growth and physiological metabolism under LD13 compared to SD10, as evidenced by higher photosynthetic efficiency, greater carbohydrate accumulation, and more robust stem development. Furthermore, S-RBL4 exerted a stronger regulatory influence than NI-RBL4 on photosynthetic traits, the activities of sugar metabolism-related enzymes, and gene expression. The photoperiodic flowering of chrysanthemum was coordinately regulated by the photoreceptor-mediated and sugar-induced pathways: CmCRY1 modulated the expression of florigenic genes (CmFTLs) and anti-florigenic gene (CmAFT) to transmit light signals, while S-RBL4 activated sucrose-responsive flowering genes CmFTL1/2 through enhanced photosynthesis and carbohydrate accumulation, thereby jointly regulating floral initiation. The anti-florigenic gene CmTFL1 exhibited dual functionality—its high expression inhibited flowering and promoted lateral branch and leaf growth, but only under sufficient sugar availability, indicating that carbohydrate status modulates its functional activity.
