“…In fruit trees, Ca directly affects fruit quality, softening, stability and shelf life, and low contents result in increased respiration and consequently affect fruit shelf life (Malavolta, 2006;Aular and Natale, 2013). Ca is also considered one of the most important nutrients for plants because it is associated with plant defense, and it may influence the growth, anatomy, morphology and chemical composition of crop species (Nagadze et al, 2014).…”

Cagaita (Eugenia dysenterica DC.) is a native fruit tree with high economical potential from the Brazilian Cerrado. However, little is known about the essential nutritional demands of its seedlings. To determine the nutrient demands of Cagaita, a greenhouse experiment was performed, in which plants were grown under hydroponic condition to assess the growth (length and diameter of stems, number of leaves, number of nodes, volume and length of roots, area of the leaf and crown and total dry weight of the leaves, stems and roots) and nutrient concentration (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn) at different time points after the plant were transferred into a nutrient solution. The seedling growth presented linear behavior until 180 days after transplantation. The total plant dry weight was 6.54 g after 180 days of transfer into the nutrient solution. The N content was positively correlated with the total dry weight and leaf area, whereas B was negatively correlated with the length of the stem and number of leaves. Macro and micronutrient concentrations presented the following order: N>Ca>K>P>Mg>S, Fe>Mn>B>Zn>Cu. A principal component analysis of the different sampling times provided important information used to define the growth variables.

“…It seems that correlation analysis could be used for tentative examination of these relations. As reported in the literature, calcium stimulates the biosynthesis of caffeic and chlorogenic acids in potato and increases the levels of enzymes involved in plant defence mechanisms [31]. It will thus be beneficial for potato growers to supplement the soil with calcium to reduce the maceration effect of pectolytic pathogens, since calcium improves tuber resistance against the pathogens.…”

Abstract:The purpose of this study was to show relationships among the levels of essential metals (zinc, iron, sodium, magnesium, calcium and potassium) and phenolic acids (caffeic, chlorogenic, ferulic, gallic, rosmarinic and syringic) in commercial herbs (lemon balm, thyme, rosemary, mint, sage and angelica) and spices (caraway, lovage, hyssop and oregano). In the herbs higher quantities of metals and phenolic compounds were found than in spices. All plants contained high levels of calcium, potassium and rosmarinic acid, but low levels of zinc and gallic acid. By using principal component and hierarchical cluster analyses several clusters were identified grouping samples originating from a plant of a particular botanical species. Multivariate analysis has also shown that the contents of phenolic acids had a stronger impact on the scattering of herbs and spices than the metals levels. Furthermore, statistically significant correlations were found between calcium and ferulic, gallic, rosmarinic and syringic acids as well as between zinc and sodium and caffeic acid. This suggests co-operate between these biologically active constituents in metabolic processes occurring in plants.

“…These indicated that PC-1 (Table 1) and PC-1 (Table 3) were related to the development of the vascular bundle of grafting union. The 7 main indicators of the 17 main indicators in PC-1 (Table 1) and PC-1 (Table 3) (41%) directly were related with calcium signal [POD (Erinle et al 2016), cellulose content (Lin et al 2016), chlorogenic acid content (Ngadze et al 2014), CDPK (Fu et al 2013), CHI , GST (Dulhunty et al 2001), and BRD (Zhou et al 2004)]. Therefore, after grafting, vascular bundle development at the scion may depend on biological responses in which intracellular calcium acts as a second messenger.…”

“…PGA is converted into phosphoenolpyruvate (PEP) with entering into second metabolism (Facchinelli and Weber 2011). Calcium can increase the second metabolism, to produce the chlorogenic acid (Ngadze et al 2014), such as cinnamic acid and coumaric acid (Clifford et al 2003). Cinnamic acid was dimerized to lignans (Heinonen et al 2001), and then reduced by PCBER to other secondary metabolites, such as phytoalexins and heartwood-protective substances (Min et al 2003).…”

Key message The anatomical and physiological signaling pathways associated with successful scion-rootstock union in nurse seedling grafting of Camellia oleifera propagation are illustrated. Abstract Grafting, the successful union between scion and rootstock, has practical and biological importance. Nurse seedling grafting, as those practiced for Camellia oleifera, often results in high cell division activity and affinity, and is usually associated with significant rootstock and scion anatomical structures changes. However, a comprehensive explanation of signaling pathways, and how they affect graft union development, is still largely unknown. The present study investigates the union formation process in C. oleifera nurse seedling grafts and determines that it consists of six stages, namely, isolation layer formation, rootstock callus differentiation, scion callus differentiation, callus proliferation and connection, cambium differentiation and connection, and conducting tissue differentiation and connection, extending over a period of 35 days. Principal components analyses of the observed changes in physiology and protein expression identified three main factors contributing to the union formation process: cell proliferation, cell differentiation, and vascular bundle development. Further analysis showed that the regulation of the union formation process can be divided into two signaling pathways, namely, calcium and MAPK, which occur during vascular bundle development and cell proliferation and differentiation, respectively.
