Effects of Fertilizers Containing Calcium and/or Magnesium on the Growth, Development of Plants and the Quality of Tomato Fruits in the Western Highlands of Cameroon

Effects of Calcium and Magnesium Fertilization on Antioxidant Activities during Cassava Postharvest Physiological Deterioration

“…This is consistent with the report of Aghofack-Nguemezi and Tatchago (2010), who also observed a shelf life prolongation of red-ripe tomatoes (Solanum lycopersicum L.) as well as a ripening delay in mature green tomatoes fertilized with Ca 2+ and Mg 2+ . In fact, it is well established that the Ca ion can delay ripening and senescence by stabilizing the cell membrane and increasing the rigidification of monolayers (Aghofack-Nguemezi and Tatchago, 2010). Furthermore, the severity and incidence of potato tuber rot was minimized by the application of Ca 2+ during potato growth (Mantsebo et al, 2014).…”

“…Furthermore, the severity and incidence of potato tuber rot was minimized by the application of Ca 2+ during potato growth (Mantsebo et al, 2014). The Mg ion affects electrostatic cross-linking between membrane components to a lesser extent than the Ca ion (Leshem, 1991;Aghofack-Nguemezi and Tatchago, 2010).…”

“…It has been suggested that the application of Ca 2+ or Mg 2+ in the soil may increase the uptake of these minerals differentially in each genotype. This effect was noted where the application of Ca 2+ and Mg 2+ fertilizers, either in the soil or on the aerial part of tomato plants, led to an augmentation of Ca concentration in the fruits (Aghofack-Nguemezi and Tatchago, 2010). In SC5, the application of Mg 2+ fertilizers enhanced Ca 2+ and Mg 2+ contents.…”

“…Plants under low Mg 2+ supply are not only very sensitive to high light intensity and heat stress but easily become chlorotic and necrotic, probably due to extensive production of ROS (Hermans et al, 2010;Kobayashi et al, 2013). In plants, when the intracellular Ca 2+ concentration is submicromolar, the concentration of closely related divalent Mg 2+ is millimolar (Aghofack-Nguemezi and Tatchago, 2010). It has been observed that the regulation of root hair development under different Mg levels was Ca-signaling-dependent (Niu et al, 2014).…”

Lipid Production, Oxidative Status, Antioxidant Enzymes and Photosynthetic Efficiency of Coccomyxa chodatii SAG 216-2 in Response to Calcium Oxide Nanoparticles

“…Such accumulation of Ca on C. chodatii could be linked to various growth and regulatory mechanisms induced by CaO NPs. Calcium plays a major role in the plant development such as increasing chlorophyll synthesis, signal transduction, pathogenic resistance, and stress tolerance [41]. In this regard, the use of CaO NPs has a positive effect on increasing the growth parameters of C. chodatii in terms of optical density, growth productivity, and dry mass acquisition in a concentration-dependent manner.…”
