“…Drier conditions favor floral induction in feijoa (Peña-Baracaldo & Cabezas-Gutiérrez, 2014) confirmed in plants of cv. Tibasosa (3 years old) where a deficit irrigation of only 25% for 406 d induced the highest number of flower buds compared to irrigation with 100, 75, 50 and 0% of water.…”

Climatic alterations affect the physiology, growth and production of the feijoa, a native plant to the higher zone between Brazil, Uruguay, Paraguay and Argentina. In Colombia, optimal growth temperatures are between 13 and 21°C (16°C). Very high temperatures (>32°C) affect pollination and fruit set, but low temperatures down to -4°C in adult plants do not cause significant damage. Thus, feijoa is a well-adapted plant to cold conditions since 3.04°C has been found as the base (minimum) temperature for the phase between flower bud and fruit set, while 1.76°C was measured as the base temperature for fruit development. The plant requires a minimum of 1000 hours of direct sunlight/year (optimum≥1500); the pyramidal form of the tree favors the entry of light into the crown organs. In the crown of a feijoa tree, trained with three branching levels of horizontal bent primary laterals, the outer middle quadrant produces the largest fruits, compared to those that grow in the upper quadrant. The reduced fruit growth is due to the excessive incidence of light (especially UV) and heat on these fruits on the periphery of the tree. In Colombia, altitudes between 1800 and 2700 meters above sea level (m a.s.l.) are adequate for growth and production of this fruit, while lower elevations favor the incidence of fruit flies. Precipitations between 700 and 1200 mm/year (max. 2000 mm) benefit the vegetative and reproductive performance of the tree, with an important drier season at the beginning of the reproductive season (flowering and fruit set). Due to the strength of its branches and the small, thick leaves, the tree is relatively wind resistant.

Esta investigación, surge a partir del inventario de los árboles que cubren el casco urbano de la ciudad, tanto en las orillas de los ríos Yanuncay y Tomebamba, como en 132 parques y en la Universidad del Azuay. El censo se llevó a cabo desde el año 2017 hasta el mes de febrero del 2023, por el Instituto de Estudios de Régimen Seccional del Ecuador (IERSE), conjuntamente con el Herbario Azuay (HA), Universidad del Azuay. Sin duda alguna, nos ha brindado luces para establecer cuantitativa y cualitativamente las dimensiones espacio-sociedad sobre la que nos encontramos actualmente y con ello considerar, de manera integral, la arborización urbana, desde sus beneficios ambientales y sociales, más allá de únicamente su uso recreativo o estético.

“…To advance in feijoa cultivation plant ecophysiology studies are necessary, including those relating to leaf area (LA) and pigment content (LP). These two traits are important in order to define the plasticity and adaptability of feijoa trees to distinct environments, such as agroforestry systems (Donazzolo et al, 2014) and under the effects of water stress (Baracaldo & Gutiérrez, 2014). In other species, LA and LP have been related to fertilization, rootstocks (Sachet et al, 2015), pest damage (Huang et al, 2014) and shading effects (Huang et al, 2015).…”

Leaf area (cm2 per leaf) and leaf pigment content are important traits that can be used to better understand a plants physiology. In this study, empirical non-destructive models for leaf area and leaf pigment based on the leaf dimensions, length (L) and width (W) in centimeters, and chlorophyll meter readings were developed for feijoa (Acca sellowiana). The experiment was carried out during January 2016 using five-year-old trees of 60 genotypes, grown under field conditions in the state of Paraná, Brazil. The proposed leaf area (LA) model was L A = 0 . 0022 L 3 + 0 . 1482 W 2 + 0 . 6159 L W + 0 . 1076 (R2 = 0.99). Three current leaf area models found in the literature were also assessed. All of the already created models were less accurate than the model proposed in this article. The proposed leaf pigment models were based on the Falker Chlorophyll Index for Chlorophyll a (A) and b (B), these were C h l a = 2 . 564 A + 13 . 098 B - 42 . 605 (R2 = 0.94), C h l b = 1 . 538 A + 3 . 287 B + 8 . 847 (R2 = 0.86) and C a r o t e n o i d s = 0 . 947 B + 8 . 943 (R2 = 0.88) expressed as µmol m-2 of leaf blade. In conclusion, the proposed models in this study were shown to be a reliable non-destructivel way of estimating A. sellowiana leaf area and leaf pigment.
