| description | Plant growth analysis has been widely used to study factors that influence plant growth. This analysis uses a set of quantitative methods that describe and analyze the growth of plants and their organs. It uses data from direct measurements (weight, area, volume) and quantifies and analyzes growth using indexes based on models defined by mathematical functions. This study conducted a functional growth analysis of diploid potato cultivars in Colombia. The functional growth analysis of diploid potato cultivars was carried out over three consecutive growing seasons in Medellín, Colombia. A randomized block design was used with two levels of fertilization and five repetitions. The first factor corresponded to the three potato cultivars, and the second factor was two fertilization levels: 260 and 778 kg of fertilizer per hectare. Samples were taken weekly, and each sample was an entire plant per experiment unit. The dry weight of each organ and the leaf area were measured. These measurements were used to calculate the relative growth rate, leaf area ratio, net assimilation rate, and specific leaf area. The development time was evaluated in accumulated degree-days with threshold temperatures of 2 and 29°C. The three cultivars recorded their highest net assimilation rate at 1,252 accumulated degree days (ADD), with values of 0.0002565, 0.0002021, and 0.0001778 g cm-2 ADD-1 in the ‘Latina’, ‘Guaneña’, and ‘Colombia’ cultivars, respectively. The Latina cultivar stood out in several physiological characteristics, including the fastest developing cultivar. ‘Latina’ also had the highest total dry mass accumulated in the cycle (271.05 g) and accumulated dry matter in tubers (237 g). |

El análisis del crecimiento de las plantas se ha utilizado ampliamente para estudiar los factores que influyen en el crecimiento. Este análisis comprende un conjunto de métodos cuantitativos que describen y analizan el crecimiento de plantas enteras y sus órganos. Utiliza datos de medidas directas (peso, área, volumen), lo que permite cuantificar y analizar el crecimiento, utilizando índices basados en modelos definidos por funciones matemáticas. Este estudio tuvo como objetivo realizar un análisis de crecimiento funcional de cultivares de papa diploides en Colombia. Se llevó a cabo un análisis funcional de crecimiento en tres variedades de papa diploides durante tres ciclos consecutivos en Medellín, Colombia. Se utilizó un diseño de bloques al azar, con dos niveles de fertilización y cinco repeticiones. El primer factor correspondió a las tres variedades de papa diploide y el segundo factor a dos niveles de fertilización: 260 y 778 kg de fertilizante por hectárea. Se tomaron muestras semanalmente y cada muestra correspondió a una planta completa por unidad experimental. Se midió el peso seco de cada órgano y área foliar que luego, se usaron para calcular la tasa relativa de crecimiento, la relación del área foliar, la tasa de asimilación neta y el área foliar específica. El tiempo de desarrollo se evaluó en grados día acumulados con temperaturas umbrales de 2 y 29°C. Las tres variedades registraron su mayor tasa de asimilación neta a los 1.252 grados día acumulados (GDA), con valores de 0.0002565, 0.0002021 y 0.0001778 g cm-2 GDA-1 para ‘Latina’, ‘Guaneña’ y ‘Colombia’, respectivamente. La variedad Latina se destacó en varias características fisiológicas, y además fue la variedad de desarrollo más rápido. ‘Latina’ también fue la que tuvo la mayor masa seca total acumulada en el ciclo (271.05 g) y mayor materia seca acumulada en tubérculos (237 g).
