The lulo plant (Solanum quitoense Lamarck) is native to South America. In Mexico, this species shows potential for the conversion of agroecosystems. It is used as food and pharmaceutical sources for metabolites. However, there are few papers related to how this species can grow under conditions outside of the Andean countries (Bolivia, Colombia, Ecuador, and Peru). The objective of this research was to evaluate the development of lulo under cloud forest conditions and the effect of inoculating the plant with mycorrhizae (Funneliformis mosseae (T. H. Nicolson and Gerd.) C. Walker and A. Schüssler, and Entrophospora colombiana Spain and N. C. Schenck) and diammonium phosphate (DAP: NPK 18-46-00) fertilization. The plant growth, leaf area, mycorrhizal colonization, and leaf mineral content were evaluated from transplant to fruit formation. The experiment was conducted under field conditions in volcanic soils (clayey Vertisol) in a cloud forest. The inoculation of E. colombiana was 86.19% of the colonization, and the content of N, K, Ca, Mg, Mn, Cu, Zn, and Fe in the leaves was the higher in these plants. The highest P content was obtained from the DAP treatment and the height of the plant was 11.8% and 12.5% in the treatments using DAP and E. colombiana, respectively. The plant growth was significantly higher in the plants inoculated with E. colombiana followed by DAP. The plants inoculated with F. mosseae registered lower values than the control. Lulo plants grow in the climate and soils of volcanic origin of the cloud forest. The results showed that AMF colonization was beneficial and outperformed the native strains. The results are new for the introduced lulo plants in Mexico and can help reduce the learning path for commercial cultivation.

“…Stomatal conductance (gs) was measured in both experiments at the end of each irrigation period (30,40,50,and 60 DAT) on the second fully expanded leaf from the upper part of the canopy using a steady-state porometer (SC-1; Decagon Devices Inc., Pullman, WA). Total plant transpiration (E) was estimated only for the experiment in pots on the same dates as gs using the gravimetric technique described by Díaz-Leguizamón et al (2016), which consists of measuring the difference in the weight of plants in their pots every 24 h.…”

Water deficit is one of the main abiotic stressors in crop production. The development of strategies to improve plant tolerance to water deficits has gained importance. Biochar application can be considered an alternative to mitigate abiotic stress. The use of coffee pulp to produce biochar could be a novel strategy for improving drought tolerance in coffee crops. Coffer plants cv. ‘Castillo’ were grown in pots or PVC pipes filled with silt loam soil in two separate experiments to evaluate the effect of coffee pulp biochar application on physiological responses under water deficit conditions. Four different biochar doses (0, 4, 8, and 16 t · ha-1) were used. A water deficit was imposed through progressive reduction irrigation (25%, 50%, 75%, and 90% of water lost via evapotranspiration). The leaf gas exchange, maximum quantum yield of PSII (Fv/Fm), biomass, and water status were measured. Reduced irrigation negatively affected the Fv/Fm, leaf gas exchange, biomass, and water status. Biochar (8 t ha-1) increased photosynthesis in both well-irrigated plants (6 µmol m-2 s-1) and with reduced irrigation (3.5 µmol m-2 s-1) compared to 0 t ha-1 biochar (reduced irrigation: 1.8 µmol m-2 s-1 and well irrigated: 3.9 µmol m-2 s-1). In conclusion, 8 t ha-1 biochar can be a recommended practice for coffee production, not only to capture carbon and reintroduce it to the soil, but also to alleviate the effects of moderate water deficit. In future investigations, biochar application can be evaluated as an alternative to soil management or coffee plant nutrition, and its interaction with drought stress scenarios.

“…This trend could be due to the biological activity of algae extracts, which are especially attractive as a natural source of bioactive molecules that promote plant growth (Khan et al, 2009). When Díaz-Leguizamón et al, (2016) compared foliar and substrate applications of algae extracts (Ascophyllum nodosum) to Solanum quitoense, foliar application was the most effective, obtaining a greater number of leaves and foliar area. The generation of the number of leaves with both applications of seaweed via foliar and substrate can be due to its composition, consisting of organic matter and NPK in the available forms, which led to the optimal nutritional status of E. grandiflorum plants (Yagoub et al, 2012).…”

Background. The use of liquid algae extract as a biostimulant when applied to leaves or roots, improves crop development and consequently yield, since by stimulating natural processes they benefit from the use of nutrients and increases resistance to conditions of biotic and / or abiotic stress. Objective. This investigation evaluated the response of two varieties of Eustoma grandiflorum to foliar and root application of algae extracts, grown in pots under nursery conditions. Methodology. Macroalgae extract was applied in a foliar way (20 mL spray) and directly to the substrate (50 mL), while drinking water was applied as the control. Results. The parameters obtained indicate that the foliar application has noticeably effects on var. Rosie for the variables root length, number of shoots, and number of leaves; while for var. Florida, the variables total plant length and number of shoots obtained greater significance. The method of application via substrate generates positive effects on the total length and stem length for var. Rosie, although the variables with the greatest noticeably were obtained from var. Florida for root length, number of leaves, and flower diameter. Implications. The low doses of the algae extracts, application form and the handling of cultural tasks during the growth of E. grandiflorum, contribute to a better absorption and/or efficiency of the fertilizers in the crop. Conclusion. The application of algae extracts favors the production of E. grandiflorum under nursery conditions, making their use a viable option to minimize the application of conventional fertilizers, thereby attenuating the effects on the environment.EFECTO DEL EXTRACTO LÍQUIDO DE ALGAS MARINAS EN EL CRECIMIENTO EN MACETA DE Eustoma grandiflorum (Raf.) Shinners).Antecedentes. El uso de extracto liquido de algas como bioestimulante cuando se aplican a las hojas o en las raices, mejora el desarrollo del cultivo y consecuentemente el rendimiento, ya que mediante la estimulación de procesos naturales benefician el aprovechamiento de nutrientes e incrementa la resistencia a condiciones de estrés biótico y/o abiótico. Objetivo. Esta investigación evaluó la respuesta de dos variedades de Eustoma grandiflorum a la aplicación foliar y radicular de extractos de algas, cultivadas en macetas en condiciones de vivero. Metodologia. El extracto de macroalgas se aplicó de forma foliar (20 mL) y directamente al sustrato (50 mL), mientras que el agua potable se aplicó como control. Resultados. Los parametros obtenidos indican que la aplicación foliar tiene efectos notables sobre la var. Rosie para las variables longitud de la raíz, número de brotes y número de hojas; mientras que para la var. Florida, las variables longitud total de la planta y número de brotes obtuvieron mayor importancia. El método de aplicación a través del sustrato genera efectos positivos sobre la longitud total y la longitud del tallo para las var. Rosie, aunque las variables con mayor notoriedad se obtuvieron de var. Florida para la longitud de la raíz, el número de hojas y el diámetro de la flor. Conclusión. La aplicación de extractos de algas favorece la producción de E. grandiflorum en condiciones de vivero, lo que hace que su uso sea una opción viable para minimizar la aplicación de fertilizantes convencionales, atenuando así los efectos sobre el medio ambiente.
