| description | Guava, because of its ability to grow in tropical and subtropical climates, has been introduced to some 60 low-latitude countries. It is adapted to a temperature range between 15 and 30°C. Outside this range, the effect of lower or higher temperatures reduces fruit set, while night temperatures of 5 to 7°C stop growth. Additionally, low temperatures hinder production, causing flowers to fall or increasing the fruit development cycle, up to 220 days. When estimating the cardinal temperatures of development, the minimum threshold temperature was 10.9°C, the optimum temperature was 17.3°C, and the maximum threshold temperature was 51.2°C. The guava tree adapts well to altitudes between 0 and 2,000 m a.s.l. in Colombia; however, there is a high genotype×environment interaction for production and quality characteristics in fruits with respect to the orchard elevation. Radiation >2,000 µmol photons m-2 s-1 decreased the fruit ascorbic acid content. An important ecophysiological factor in guava is water, and crops require between 1,000 to 2,000 mm year-1. It withstands waterlogging for several days, but excess precipitation and atmospheric humidity decrease fruit quality considerably. However, this tree is classified as moderately drought-tolerant to stress from water deficits, affecting flowering and fruit set. It is also moderately tolerant to salinity, depending on the variety, supporting electrical conductivities up to 1.5-1.8 dS m-1. Generally, guava can be cultivated in a wide range of tropical and subtropical areas, where it is preferred because of its high nutritional and medicinal contents and its aptitude for transport and handling. |

La guayaba, debido a su habilidad de crecer en climas tropicales y subtropicales, ha sido introducida en unos 60 países de las latitudes bajas. Se adapta a rangos de temperatura entre los 15 y 30°C. Fuera de este rango, el efecto de temperaturas inferiores o superiores reducen, en primer lugar, el cuajamiento de los frutos, y temperaturas nocturnas de 5 a 7°C detienen el crecimiento. Adicionalmente, las temperaturas bajas dificultan la producción generando caída de flores o aumentando el ciclo de desarrollo del fruto hasta unos 220 días. En una estimación de las temperaturas cardinales de desarrollo se encontraron como temperatura umbral mínima 10,9°C, temperatura óptima 17,3°C y temperatura umbral máxima 51,2°C. El árbol de guayaba se adapta bien a altitudes entre 0 y 2.000 msnm en Colombia; sin embargo, existe alta interacción genotipo (variedad)×ambiente referente a las características de producción y calidad del fruto con respecto a la elevación del sitio. Radiaciones >2.000 µmol fotones m-2 s-1 disminuyeron el contenido del ácido ascórbico en el fruto. Un factor ecofisiológico importante en la guayaba es el agua ya que los cultivos exigen entre unos 1.000 a 2.000 mm año-1. Soportan el anegamiento de varios días; pero mucha precipitación y humedad atmosférica disminuyen la calidad del fruto considerablemente. No obstante, este árbol está clasificado como moderadamente tolerante a la sequía, el estrés por déficit hídrico afecta la floración y el cuajamiento de los frutos. Es también moderadamente tolerante a la salinidad, dependiendo de la variedad, con conductividades eléctricas hasta máximo 1,5-1,8 dS m-1. En general, se puede concluir que la guayaba se puede cultivar en una amplia gama de áreas tropicales y subtropicales donde es preferida por su alto contenido nutricional y medicinal y su aptitud para el transporte y manejo.
