“…Zheng et al [ 30 ] reported that a high light intensity (350 µmol∙m −2 ∙s −1 PPFD) increased the photosynthetic capacity of the mother plant and the primary runner plant of strawberry. Furthermore, CO 2 enrichment increased the photosynthetic rate of Gerbera jamesonii [ 31 ]. G. littoralis is a crop native to coastal dunes and grows in high-light natural environments.…”

This study aims to determine the effect of different CO2 concentrations and light intensities on the growth, photosynthetic rate, and bioactive compound content of Glehnia littoralis Fr. Schmidt ex Miquel in a closed-type plant production system (CPPS). The plants were transplanted into a deep floating technique system with recycling nutrient solution (EC 1.0 dS·m-1 and pH 6.5) and cultured for 96 days under a temperature of 20 ± 1 °C, a photoperiod of 12/12 h (light/dark), and RGB LEDs (red:green:blue = 7:1:2) in a CPPS. The experimental treatments were set to 500 or 1500 µmol∙mol−1 CO2 concentrations in combination with one of the three light intensities: 100, 200, or 300 µmol∙m−2∙s−1 photosynthetic photon flux density (PPFD). The petiole length of G. littoralis was the longest in the 500 µmol∙mol−1 CO2 concentration with the 100 µmol∙m−2∙s−1 PPFD. The fresh weight (FW) and dry weight (DW) of shoots and roots were the heaviest in the 300 µmol∙m−2∙s−1 PPFD regardless of the CO2 concentration. Higher CO2 concentrations and light intensities produced the greatest photosynthetic rates. However, the SPAD value was not significantly different between the treatments. Higher light intensities produced greater content per biomass of chlorogenic acid and total saponin, although the concentration per DW or FW was not significantly different between treatments. The first and second harvest yields were the greatest in the 300 µmol∙m−2∙s−1 PPFD, regardless of the CO2 concentration. These results show that the 300 µmol∙m−2∙s−1 PPFD enhanced the growth, photosynthetic rate, and bioactive compound accumulation of G. littoralis, regardless of the CO2 concentration in a CPPS.

“…Além disso, a camada de cera que recobre a epiderme é mínima ou inexistente, não constituindo uma proteção eficiente contra a desidratação. Para agravar o quadro, mudas micropropagadas podem ter conexões vasculares deficientes, o que contribui para reduzir o transporte de água no seu interior (ĎURKOVIČ;ČAŇOVÁ;PICHLER, 2009;XU et al, 2014).…”

“…Vários fatores estão envolvidos na morte ou sobrevivência das mudas durante a aclimatização, tais como o genótipo, estresse hídrico, alteração do metabolismo heterotrófico para autotrófico (anormalidades fisiológicas e estruturais, menor controle da perda de água), infecção por patógenos e o estresse pela alteração na radiação. O ambiente de cultivo in vitro pode afetar e conduzir a diferentes atividades enzimáticas, resultando em várias mudanças nos processos metabólicos da planta, afetando significativamente a aclimatização da muda (CHAKRABARTY;DATTA, 2008;ZHANG et al, 2009;XU et al, 2014).…”

Phalaenopsis, an epiphytic crassulacean acid metabolism (CAM) plant, requires moderate variations of day/night temperatures for flowering. In this study, changes in chlorophyll content, chlorophyll fluorescence, sugar components, titratable acidity and soluble protein content in Phalaenopsis leaves during flowering were observed. Comparative proteomic analysis of Phalaenopsis leaves in the vegetative and flowering phase was performed for the first time using iTRAQ (isobaric tags for relative and absolute quantification). A total of 126 proteins were differentially expressed in Phalaenopsis leaves. Analysis of potential functions revealed that the major categories of predicted function of the up-regulated proteins were protein destination (27 %), photosynthesis (15.9 %), primary metabolism (14.3 %) and defense (12.7 %) in the flowering phase, while the major categories of predicted function of the down-regulated proteins were protein destination (33.3 %), primary metabolism (20.6 %), transportation (14.3 %) and signal transduction (11.1 %). Proteome profile analysis indicated that the proteome changes were consistent with changes in sugar and protein metabolites. Some novel proteins were differentially expressed, most of which were identified as signaling proteins, including 14-3-3 proteins, fibrillin, rapid alkalinization factors (RALF), the Ras-related protein RABB1c, calreticulin and calmodulin. Histone, importin alpha, multidrug resistance proteins and the ABC transporters were also differentially expressed. These results provide insights into the mechanisms that regulate flowering in complex flowering plants.
