Strengths and limitations of Bio∑TERM®, a thermal time calculator program
Temperature is one of the main determinants of plant growth. Growth simulation models based on base temperatures and thermal accumulation requirements for each species or crop are widely used to model their behavior at different latitudes. But the calculation of the thermal time necessary to complete certain growth phases requires as input the average daily temperatures of the period to be calculated and the base temperature (Tb) of the species, information that is sometimes difficult to obtain. The Bio∑TERM® program was designed with the objective of facilitating and simplifying the conversion of units from calendar time to thermal time and vice versa in Argentina. For this, it has two databases, one with average daily temperatures for the entire country for 50 years and another with base temperatures of different species and cultivars. Both databases allow quick and simple calculation, transforming calendar times in thermals for a wide set of species, and even for those that are not incorporated into it and the user knows their Tb, or transform a known thermal time into a calendar. The program proved to be very accurate, when real vs. calculated data were compared, for different time series of average temperatures, showing a high degree of adjustment when real data are not available. The Bio∑TERM® program tries to be a powerful tool and at the same time provide a simple solution both for researchers who wish to transmit or disseminate knowledge that is very difficult to apply in calendar time, as well as for advisors and producers who want to use said knowledge in a more friendly way.

La temperatura es uno de los principales factores que determinan el crecimiento y el desarrollo de las plantas. Los modelos de simulación de crecimiento a partir de las temperaturas bases (Tb) y los requerimientos de acumulaciones térmicas para cada especie o cultivo son muy utilizados para modelar el comportamiento de los mismos en diferentes latitudes. Sin embargo, el calcular el tiempo térmico necesario para cumplir determinadas fases de crecimiento requiere como insumos las temperaturas medias diarias del período a calcular y la temperatura base de la especie, una información que suele ser difícil de conseguir. El programa Bio∑TERM® fue pensado para facilitar la conversión de unidades de tiempo calendario a tiempo térmico y viceversa en toda la Argentina. Para ello, cuenta con dos bases de datos: una, de 50 años de temperaturas medias diarias de todo el país; y otra, de temperaturas bases de diferentes especies y cultivares. Ambas permiten transformar rápida y sencillamente los tiempos calendarios en térmicos para un amplio conjunto de especies, incluso para aquellas que no están incorporadas, pero para las que se conoce su Tb; también permite transformar un tiempo térmico conocido a tiempo calendario. El programa mostró ser muy preciso cuando se compararon datos reales vs. calculados para diferentes series temporales de temperaturas medias, y presentó un grado alto de ajuste cuando no se cuenta con datos reales. Bio∑TERM® intenta ser una herramienta potente y, a la vez, brindar una solución simple para los investigadores que deseen transmitir conocimientos que en tiempo calendario son complejos de aplicar, y para los asesores y productores que quieran usar dicho conocimiento de una manera más amigable.
