| description | Lulo (Solanum quitoense) is a promising Andean fruit tree that is highly valued in international markets because of its nutritional characteristics, flavor, aroma, and high content of vitamins A and C with antioxidant properties. However, certain sanitary problems, such as Fusarium oxysporum and soil nematodes, pose challenges to the competitiveness of lulo crops. Cultivating lulo plants grafted onto resistant patterns, such as S. hirtum, is a plausible solution to these sanitary issues; so, determining the behavior of grafted plants is relevant. In this study, the phenology and growth dynamics of grafted lulo plants were evaluated with functional analyses based on thermal time (degree days-DD). Completion of the vegetative phase of the lulo required 561 DD from planting to the onset of flower bud sprouting, 715 DD to reach anthesis, 801 DD for fruit set, and a cumulative total of 2,464 DD to reach fruit ripening. The functional analyses showed that Richards’s model fit the dynamics of the growth variables (height, leaf area index, crop growth index, total dry weight, leaf dry weight, and stem dry weight). Of the total plant dry biomass, 39.7% corresponded to the stems, 33.8% was from the fruits, 15.54% was from the leaves, 10.56% was from the roots, and 0.4% was from the flowers. The yield was not affected by the grafting process of lulo S. quitoense onto S. hirtum stocks; on the contrary, the crop population and productivity were maintained for a longer time. |

El lulo (Solanum quitoense) es un prometedor árbol frutal andino muy apreciado en los mercados internacionales por sus características nutricionales, su sabor y aroma, y su alto contenido de vitaminas A y C con propiedades antioxidantes. Sin embargo, ciertos problemas sanitarios, como Fusarium oxysporum y nematodos del suelo, plantean problemas para la competitividad del cultivo del lulo. Al respecto, el cultivo de plantas de lulo injertadas en patrones resistentes, como S. hirtum, es una solución plausible a estos problemas sanitarios y, por lo tanto, determinar el comportamiento de las plantas injertadas es una cuestión relevante. En este estudio se evaluó la fenología y la dinámica de crecimiento de las plantas de lulo injertadas mediante análisis funcionales basados en el tiempo térmico (grados día-DD). La finalización de la fase vegetativa del lulo requirió 561 DD desde la plantación hasta el inicio de la brotación del botón floral, 715 DD para alcanzar la antesis, 801 DD para el cuajado de los frutos y un total acumulado de 2.464 DD para alcanzar la maduración de los frutos. Los análisis funcionales mostraron que el modelo de Richards se ajustaba a la dinámica de las variables de crecimiento (altura, índice de superficie foliar, índice de crecimiento del cultivo, peso seco total, peso seco de la hoja y peso seco del tallo). Del total de la biomasa seca de la planta, el 39,7% correspondía a los tallos, el 33,8% a los frutos, el 15,54% a las hojas, el 10,56% a las raíces y el 0,4% a las flores. El rendimiento no se vio afectado por el proceso de injerto de lulo S. quitoense en S. hirtum; por el contrario, la población de los cultivos y su productividad se mantuvieron durante más tiempo.
