“…Since most species have not been tested for cold adaptations, absence of data does not necessarily indicate absence of traits. However, since cold climates arose after major radiations in seed plants, presence data (based on Krug, 1991; De la Rosa et al, 2000; Kawamata et al, 2002; Wilson et al, 2002; Karlson et al, 2004; Streck and Schuh, 2005; Lopez and Runkle, 2006; Fausey and Cameron, 2007; Kalberer et al, 2007; Mewes and Pank, 2007; Rohwer and Heins, 2007; Svendsen et al, 2007; Padhye and Cameron, 2008, 2009; Pietsch et al, 2009; Zlesak and Anderson, 2009; Biasi et al, 2010; Byard et al, 2010; Ghelardini et al, 2010; Kaymak and Guvenc, 2010; Kubota et al, 2010; Lenahan et al, 2010; Rantasen and Palonen, 2010; Caffarra et al, 2011; Cave et al, 2011; Charrier et al, 2011; Dogramaci et al, 2011; Lin et al, 2011; Adhikari et al, 2012; Andreini et al, 2012; Bilavcik et al, 2012; Diaz-Riquelme et al, 2012; Nishitani et al, 2012; Sanchez-Perez et al, 2012; Whitman and Runkle, 2012; Alessandro et al, 2013; Guzy-Wrobelska et al, 2013; Jones et al, 2013; Mojtahedi et al, 2013) indicates multiple origins of cold adaptive traits across the phylogeny.…”

Flowering plants initially diversified during the Mesozoic era at least 140 million years ago in regions of the world where temperate seasonal environments were not encountered. Since then several cooling events resulted in the contraction of warm and wet environments and the establishment of novel temperate zones in both hemispheres. In response, less than half of modern angiosperm families have members that evolved specific adaptations to cold seasonal climates, including cold acclimation, freezing tolerance, endodormancy, and vernalization responsiveness. Despite compelling evidence for multiple independent origins, the level of genetic constraint on the evolution of adaptations to seasonal cold is not well understood. However, the recent increase in molecular genetic studies examining the response of model and crop species to seasonal cold offers new insight into the evolutionary lability of these traits. This insight has major implications for our understanding of complex trait evolution, and the potential role of local adaptation in response to past and future climate change. In this review, we discuss the biochemical, morphological, and developmental basis of adaptations to seasonal cold, and synthesize recent literature on the genetic basis of these traits in a phylogenomic context. We find evidence for multiple genetic links between distinct physiological responses to cold, possibly reinforcing the coordinated expression of these traits. Furthermore, repeated recruitment of the same or similar ancestral pathways suggests that land plants might be somewhat pre-adapted to dealing with temperature stress, perhaps making inducible cold traits relatively easy to evolve.

“…Conversely, insufficient vernalization can result in incomplete or delayed flowering, which can cause considerable monetary losses to growers. In general, after the fulfilment of vernalization requirements, exposure to higher temperature is needed for the subsequent flowering [ 52 ].…”

“…E. Wimm. were −2.5 °C and 5–10 °C, respectively [ 53 ], while the complete flowering of Campanula ‘Birch Hybrid’ was achieved after a five-week vernalization treatment at 2.5–7.5 °C or after a nine-week treatment at 0–12.5 °C [ 52 ]. Therefore, the selection of appropriate inductive temperatures is important for commercial production of herbaceous perennials.…”

The scheduling of plant production is a critical aspect in modern floriculture since nowadays, sales are not oriented toward the recurring holidays as in the past, but always more toward impulse buying, implying a more diverse and constant demand on the market. This requires continuous production, often regulated by precise commercial agreements between growers and buyers, and between buyers and dealers, particularly in large-scale retail trade. In this scenario, diverse techniques to modulate the duration of the growing cycle, by hastening or slowing down plant growth and development, have been developed to match plant flowering to the market demand. Among the numerous approaches, the manipulation of climatic parameters in the growth environment is one of the most common in greenhouse floriculture. In this review, we summarize the physiological and biochemical bases underlying the main mechanisms of flowering, depending on the plant reaction to endogenous signals or environmental stimuli. In addition, the strategies based on the control of temperature (before or after planting) and light environment (as light intensity and spectrum, and the photoperiod) in the scheduling of flower and ornamental crop production are briefly described.

“…Vernalization has been defined as the acquisition or acceleration of the ability to flower by a chilling treatment. The period of vernalization has a quantitative effect on the flowering response until it is maximal, and therefore, increasing the period of vernalization progressively increases flowering up to a point (Lang, 1965;Padhye and Cameron, 2009). Insufficient vernalization can result in incomplete or delayed flowering (Padhye and Cameron, 2008).…”

Dianthus japonicus Thunb. (D. japonicus) is a biennial with promising floricultural traits, but its commercial appeal is limited by the long time between propagation and flowering. We assessed the effect of juvenile phase, vernalization, and photoperiod on flowering of D. japonicus. Plants were grown in a plug until they had acquired nine, 14, or 16 leaf pairs, and then exposed to a vernalization period of 0, 3, 6, or 12 weeks at 5°C. At the end of the vernalization period, plants were transferred to either long-day treatment or short-day treatment for 10 weeks. In D. japonicus, the numbers of new nodes and leaves were correlated with the vernalization period. Plant height was correlated with the number of leaf pairs. As the vernalization period lengthened, the plants produced more nodes and leaves regardless of their growth stage. The maximum plant height increase was over 24.7 cm in the plants that had 16 leaf pairs at 10 weeks after the start of the photoperiod treatment, regardless of the photoperiod. Plants with 14 or 16 leaf pairs and a vernalization period of 12 weeks flowered regardless of photoperiod treatment. None of the plants that had been vernalized for less than 12 weeks flowered or produced flower buds. We noted a significant difference in the flowering response among plants based on the number of leaf pairs and vernalization period. We conclude that D. japonicus plants must form 14 to 16 leaf pairs before they can respond to vernalization and require at least 12 weeks of vernalization before flowering. This species has a qualitative response to vernalization and is dayneutral.
