“…It should be noted that this conversion of acids into sugars is essential for quality (flavor and aroma) and nutritional value in fruits (VALLARINO; OSORIO, 2019). The TA presented significant differences between 1-MCP doses at 4 °C (2.57) and 16 °C (2.24), as reported by Álvarez-Herrera et al (2022), who stated that 1-MCP influences the metabolism of carbohydrates and organic acids. This confirmed that, when feijoa fruits are refrigerated, organic acids degrade at a lower rate than when fruits are stored in the environment.…”

Feijoa is a promising crop in Colombia with high export potential. However, its postharvest shelf-life is short since it is a climacteric fruit with high respiration rates and susceptibility to fruit flies. Techniques such as refrigeration and the use of 1-methylcyclopropene (1-MCP) increase the post-harvest period and prolong fruit quality. The objective of this research was to evaluate the effect of different storage temperatures and 1-MCP doses on postharvest feijoa fruits. A completely randomized design with a 2x4 factorial arrangement was used, where the first factor was temperature (4 and 16 °C), and the second factor was the 1-MCP dose (0, 30, 60 and 90 µg L-1), for a total of eight treatments. The treatments at 4 °C presented lower values for mass loss and respiratory rate, while luminosity, chromaticity, soluble solids and antioxidant activity showed the highest values. The lowest 1-MCP doses at 4 °C had the highest values of titratable acidity and endocarp tone; on the contrary, the highest doses at 4 and 16 °C presented the highest values of phenolic compounds. The refrigerated feijoa fruits had a shelf-life between 36 and 42 days, while those stored at 16 °C only had commercial quality for 14 days, highlighting the importance of cold storage.

“…Indeed, the highest N concentration was obtained in roots of plants under T1 containing the lowest compost content (40%), which may be attributed to a possible better balance between NO 3 − and NH 4 + in the substrate mixture for these tissues (Table 1). This species positively responds to increasing N applications, applied to both the soil and the leaves [6]. Conversely, all other macronutrients in roots were higher in plants under T3, which contained 80% compost.…”

“…Moreover, research on its cultivation is still in its infancy [5]. In fact, the lulo-growing industry has developed as a result of initiatives taken by the growers themselves, without significant scientific support in terms of research, technology and innovation [6]. Therefore, there is a big need for carrying out research aimed at overcoming some technical limitations that currently limit its expansion and competitiveness, including Horticulturae 2022, 8, 1200 2 of 13 studies on the effect of substrates on germination and production of healthy seedlings in containers under greenhouse or nursery conditions.…”

Organic Substrates Differentially Affect Growth and Macronutrient Concentrations of Lulo (Solanum quitoense Lam.) Seedlings

We tested the effect of varying percentages (v/v) of peatmoss and compost (60/40, T1; 40/60, T2; and 20/80, T3) on growth and macronutrient concentration of lulo (Solanum quitoense Lam.) seedlings in a completely randomized experiment with ten replicates under greenhouse conditions. Lulo seedlings displayed higher plant height and stem diameter when grown in T1 and T2, as compared to T3. In root tissues, N concentration was higher in plants grown in T1, and the same trend was observed in leaves, though differences were not significant in the latter. All other nutrient concentrations analyzed in root tissues were higher in plants under T3. These results are directly related to a higher biomass production in roots as compared to shoots (52.5% higher) found in T3. In leaf tissues, however, significant increases in plants exposed to T3 were only evident for Ca and S concentrations (i.e., 10.6 and 2.6 g kg−1 DBW). Considering dry biomass weight (DBW), lulo plants exhibited a significant and positive correlation between shoot (ShDBW) and total dry biomass (TDBW), whereas low and negative correlations were observed between root DBW and ShDBW. Therefore, a peatmoss/compost ratio of 0.66 (40/60, T2) results in a better plant growth performance, ensuring a good plant nutrient status for lulo seedlings.

“…Likewise, Ref. [72] found that, by removing Mg from the nutrient solution, the height of the lulo plants decreased significantly and possibly lacked Mn, Mo y Cu.…”

Plant Height and Stem Diameter of Solanum quitoense Lamarck Improved with Applications of AMF and Biostimulants

et al. 2023

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.
