“…Known as naranjilla in Ecuador and as lulum in Peru, this crop from the Solanaceae family is grown in Colombia, Ecuador, Peru, Venezuela, Guatemala, Mexico, Costa Rica, Dominican Republic, and Panama. The plant produces a spherical fruit with a diameter that varies between 3 and 8 cm [ 4 ]. In the last years, the lulo fruit has raised considerable interest in the global market due to its organoleptic characteristics, pleasant aroma, and acidic and refreshing taste [ 5 ].…”

Lulo (Solanum quitoense Lam.) is a Colombian fruit that is mostly used in the preparation of homemade juice as well as natural remedy for hypertension. The aim of this study was to determine physicochemical and antioxidant properties (antioxidant capacity, total phenols, flavonoids and spermidine content, and polyphenolic compounds profile by liquid chromatography—mass spectrometry (LC-MS)) of the lulo fruit and its juice. Additionally, vacuum impregnation (VI) properties of the fruit and the effect of high homogenization pressure (50, 100, and 150 MPa) on the juice properties were studied. The results revealed a good availability and impregnation capacity of the pores in fruits with similar maturity index. The main differences observed between the juice and fruit derive from removing solids and bioactive components in the filtering operation. However, the effect of high-pressure homogenization (HPH) on particle size and bioactive compounds increases the antiradical capacity of the juice and the diversity in polyphenolics when increasing the homogenization pressure.

“…Foliar applications of nitrogen decreased the detrimental effect of waterlogging in the lulo (Flórez-Velasco et al 2015). Ramírez et al (2018) reported that the lulo plants respond to the photoperiod with respect to flowering. Messinger & Lauerer (2015) found under greenhouse conditions in Germany that, in plants under long day conditions (summer in Germany), the period between the flower bud appearance and fruit set becomes shorter, reducing the flowering period and time until harvest.…”

The high Andean areas present ecophysiological conditions suitable for the cultivation of many fruit species, especially of the Solanaceae family. The objective of this review is to present important ecophysiological information on four fruit trees grown in cold climates: Cape gooseberry, tree tomato, lulo, and sweet cucumber o pear melon. The cape gooseberry is a species well adapted to cold tropical climate, it is grown between 1,800 and 2,700m a.s.l., with temperatures of 13 to 16°C. It is highly adapted to high solar radiation and to the abrupt changes between the day and night temperatures. It requires a precipitation of 1,000 to 1,800mm year-1 uniformly distributed throughout the year, and is sensitive to water deficit but also to waterlogging and strong winds. The tree tomato, in Colombia, produces better from 1,800 to 2,600m a.s.l., with temperatures between 13 and 20°C, annual rainfall between 1,500 and 2,000mm, relative humidity around 80%, and solar brightness of 1,800 to 2,300 hours/year; it does not resist strong winds, water deficit or waterlogging. The lulo requires environments with high precipitation (1,000 to 2,800mm) and penumbra because it loses a lot of water through transpiration but waterlogging also affects it; it grows well in areas between 1,600 to 2,400m a.s.l. and 16 to 24°C, with photosynthesis rates up to of 34.03µmol CO2 m-2 s-1. The sweet cucumber is of growing interest in many exotic fruit markets, it grows at 900-2,800m a.s.l. with temperatures <25°C and responds well to air enrichment with CO2.

“…Its center of origin is located between the Colombian and Ecuadorian Andes (Heiser and Anderson, 1999;Lobo and Medina, 2000;Ramírez and Davenport, 2020;Ramírez 2021). Several authors, including to Ramírez et al (2018); Arias and Rendón (2014); Muñoz et al (2013);Paull and Duarte (2012) and Medina et al (2009), mention various factors that make lulo a promising fruittree with high productive potential, including a high genetic variability with related species in the Andean region, proper niches for planting, consumer acceptance of the fruit and agroindustrial potential.…”

Lulo (Solanum quitoense Lam.) is a fruit tree of Andean origin of national economic importance in Colombia, which constitutes an important source of employment for farmers and their families. Vascular and root wilt caused by the fungus Fusarium oxysporum is one of the most limiting diseases in the production of this species, causing low yields and considerable economic losses. As an effective control alternative for this pathogen, the identification of genotypes with resistance that can be used in breeding programs is being considered. The objective of this work was to evaluate the response of 22 lulo genotypes to the artificial inoculation of Fusarium oxysporum to identify possible sources of pathogen tolerance. F. oxysporum was inoculated on 22 genotypes of lulo plants following the method of wounded roots through artificial cutting. Distilled water inoculation and “La Selva” resistant lulo hybrid was used as control. The traits evaluated correspond to plant height, stem diameter, days to the onset of symptoms, incidence and severity. The fungus isolation was highly aggressive in S. quitoense and S. hirtum, with 96 and 84% severities, respectively. Five resistant genotypes were identified, namely 15C, 36B, HSF1, HSF10, and HSF36, which presented incidences and severities of 0% and can be considered for multi-environmental evaluation tests to determine their productive potential or they can be considered as parents for breeding programs of the species. Other genotypes, such as 15B and HSF15, showed average severities of 28 and 20%, respectively; however, thesetwo genotypes survived throughout the experiment, suggesting tolerance to the pathogen.
