Aspects of Crop and Physiology of Feijoa (Acca sellowiana [Berg] Burret). A Review
Feijoa is a fruit tree with great potential for human consumption, cultivated between 1,800 and 2,700 m.a.s.l. in Colombia. It is well adapted to cold temperatures, resisting temperatures <0 °C for a short time, while temperatures >32 °C affect its flowering. It has base temperatures f...

| description | Feijoa is a fruit tree with great potential for human consumption, cultivated between 1,800 and 2,700 m.a.s.l. in Colombia. It is well adapted to cold temperatures, resisting temperatures <0 °C for a short time, while temperatures >32 °C affect its flowering. It has base temperatures for its state from flower bud to anthesis with 2.89 °C, from anthesis to fruit set with 3.04 °C and from fruit set to harvest 1.76 °C. The tree thrives well in in alluvial soils, deep and rich in organic matter ones. In the tree pruning, the cone formation with three levels of horizontal bent branches and the elimination of suckers are important, thus promoting flowering and longevity of the tree. In the few physiological studies, a low photosynthetic rate (on average between 4 and 6 μmol CO2 m-2 s-1) was found, with high energy demand during flowering, while the transpiration rate of the crown increases with irradiance, temperature and the decrease in relative humidity, showing a greater number of leaf stomata in the upper layer of the crown (91/mm2), compared to the lower layer (78/mm2). The beginning of the reproductive stage is favored by dry conditions, as well as potassium fertilization with 0.5% KH2PO4. In Colombia, fruits of greater caliber and higher productions are achieved through cross-pollination by blackbirds (Turdus fuscater). The fruit needs about 120 to 150 days to develop and there are productions between 30 and 40 kg/tree (≥20 t ha-1). The green color of the fruit in all its stages makes it difficult to determine its maturity state. |

La feijoa es un frutal con gran potencial para el consumo humano, que se cultiva entre los 1800 y 2700 msnm en Colombia. Está bien adaptada a temperaturas bajas, resistiendo por corto tiempo temperaturas <0 °C, mientras que temperaturas >32 °C afectan su floración. La temperatura base para botón floral a antesis es 2,89 °C, de antesis a cuajamiento del fruto es de 3,04 °C y del cuajamiento del fruto a cosecha, 1,76 °C. El árbol crece muy bien en suelos aluviales, profundos y ricos en materia orgánica. En la poda del árbol es importante la formación en cono con tres niveles de ramas agobiadas y la eliminación de los chupones, para fomentar así la floración y la longevidad del árbol. En los pocos estudios fisiológicos se encontró una tasa fotosintética baja (en promedio entre 4 y 6 μmol CO2 m-2 s-1), con gran demanda energética durante la floración, mientras la transpiración aumenta con la irradiancia, la temperatura y la disminución de la humedad relativa, mostrando un mayor número de estomas foliares en el estrato superior de la copa (91/mm2), comparado con el inferior (78/mm2). El inicio de la etapa reproductiva está favorecida por las condiciones más secas y por la fertilización con KH2PO4 al 0.5 %. En Colombia, frutos de mayor calibre y producciones más altas se logran a través de la polinización por la mirla negra (Turdus fuscater). El fruto necesita entre 120 y 150 días para desarrollarse y se presentan producciones entre 30 y 40 kg/árbol (≥20 t ha-1). El color verde del fruto en todos sus estados dificulta la determinación del grado de madurez.
