“…In addition, all the treatments increased the Mg content, making it possible to postulate that the duckweed extract, exerting a beneficial effect on this nutrient acquisition, activated the enzyme ribulose 1,5-bisphosphate carboxylase/oxygenase and stimulated the chlorophyll content [67]. Chloroplasts contain 35% of Mg, and of this, about 25% is bound to the pigment [68]. The effect on Ca was more modest than those found for the other elements mentioned; only the higher duckweed concentration increased its content (Table 2).…”

Biostimulant Effects of an Aqueous Extract of Duckweed (Lemna minor L.) on Physiological and Biochemical Traits in the Olive Tree

Biostimulants are becoming increasingly popular in agriculture for their ability to induce beneficial effects in crops, paving the way towards the identification of new materials with biostimulant potential. This study evaluated the potential of different concentrations of an aqueous extract (0.25%, 0.50%, and 1.00%, dry weight/water volume, respectively) obtained from duckweed (Lemna minor L.) to stimulate olive plants. Leaf net photosynthesis (Pn), leaf transpiration rate (E), stomatal conductance (gs), sub-stomatal CO2 concentration (Ci), chlorophyll content and other plant growth parameters were investigated. As a result, the extract improved Pn, gs, Ci, chlorophyll content and plant biomass production (leaf fresh and dry weight). Furthermore, the duckweed extract generally increased the uptake of nitrogen (N), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe) and zinc (Zn), while it did not influence the content of sodium (Na), manganese (Mn) and copper (Cu). The untargeted metabolomic profiling of the extract revealed the presence of signalling compounds (including phytohormones), phenolics and glutathione. Such broad diversity of bioactives may support the stimulatory potential observed in olive. In summary, this study revealed for the first time that duckweed could be seen as a promising species to obtain extracts with biostimulant properties in olive trees.

“…El Mg es muy importante en procesos metabólicos y reacciones bioquímicas en las plantas, como la formación de clorofila, por eso, el aporte adecuado de este nutriente es de fundamental importancia en el cultivo de la papa y la producción de tubérculos (Barroso et al, 2021). Estos investigadores instalaron dos experimentos (I y II) simultáneos en un invernadero.…”

“…A deficit of these nutrients leads to less translocation of photoassimilates to the tubers, low mechanical resistance, low specific gravity, and multiple physiological disorders, such as hollow heart Schabow & Palta, 2019). In contrast, doses higher than the optimum can lead to negative effects due to excess of other nutrients, loss of fertilizer, and cost overruns (Wang et al, 2018;Barroso et al, 2021).…”

Critical dilution curves for calcium, magnesium, and sulfur in potato (Solanum tuberosum L. Group Andigenum) cultivars Diacol Capiro and Pastusa Suprema

2022

Diagnostic tools must be developed to optimize the management of calcium (Ca), magnesium (Mg), and sulfur (S) in potato crops. This research aimed to develop the critical dilution curves for Ca, Mg, and S in potato (Solanum tuberosum L. Group Andigenum), establishing harvest indices and characterizing the nutrient relationships. Four field experiments were established in two growth cycles in the localities of Facatativá (high fertility soils) and Chocontá (low fertility soils) in Colombia. Two cultivars (Diacol Capiro and Pastusa Suprema) and two levels of fertilization (0 and 100% of macro and micronutrients) were evaluated. The dry biomass and Ca, Mg, and S concentration in tubers and aerial parts were measured from the formation of main stems until tuber maturation; this information was used to calculate the critical concentrations (Cac, Mgc, Sc), harvest indices, and nutrient correlations. The critical curves established were for Capiro: Cac = 1.7326W-0.2956, Mgc = 0.7191W-0.2803, Sc = 0.6461W-0.3904 and for Suprema: Cac = 1.523W-0.2559, Mgc = 0.6507W-0.236, Sc = 0.7669W-0.3932. Critical levels were established for five phenological stages. Capiro had a higher accumulation of Ca, Mg, and S in the tubers independently of locality, while Suprema had better performance in Chocontá. The accumulation of mineral nutrients in the tubers followed the order Ca<Mg<S. Capiro was a genotype with greater Ca-Mg-S uptake and better adaptation to locations. The Cac, Mgc and Sc curves provided a tool to carry out the nutritional diagnoses at critical stages of development and they are the first ones reported for potato of Group Andigenum.
