Fenología reproductiva de Stenocereus thurberi (Cactaceae) en una región de transición del norte de Sinaloa, México

Abstract: RESUMENLos patrones fenológicos, moldeados por las interacciones físicas y bióticas en hábitats marginales, pueden revelar características únicas para la permanencia de una población. La fenología de Stenocereus thurberi, una cactácea columnar del Desierto Sonorense, ha mostrado variación geográfica asociada con el clima y los polinizadores, pero no se conoce su comportamiento en ambientes más húmedos de su área de distribución. El objetivo de esta investigación es describir la dinámica reproductiva y la estru… Show more

“…Warren et al (2017) relate this common habit in several cacti with the efficiency of carbohydrate transport from the tissues that receive more solar radiation toward the reproductive tissues. The reproductive phenology pattern observed in E. acida is similar to those reported for other columnar cacti (Novoa et al, 2005;Bustamante and Búrquez, 2008;Santos et al, 2008;Salomón-Montijo et al, 2016). The flower bud phase was recorded during the whole sampling period (9 mo) between the end of autumn and beginning of summer (May to January), although more intensely toward the end of winter and beginning of spring after to autumn rainfall (Figure 4A).…”

“…However, the reproductive stages in this species are asynchronous, given that they present flower buds, flowers and fruits in the same season. A similar case occurs in the phenology of E. iquiquensis and E. acida, which is advantageous, since only a part of the reproductive structures would be affected in the event of adverse conditions (biological or climatic), ensuring the longterm reproductive success (Pimienta-Barrios & Nobel 1995, Pinto 2007, Salomón-Montijo et al 2016, Salvatierra 2020. Asynchrony also benefits the associated fauna, as it results in a permanent source of food.…”

“…Las variaciones en los patrones de floración y fructificación son atribuidas a factores físicos, principalmente la temperatura y disponibilidad de agua (Wang et al 2016). Las flores pueden ser fecundadas por un sistema de polinizadores diurnos y nocturnos integrado por murciélagos, abejas, aves e insectos cuya presencia determina la producción de frutos y semillas (Bustamante et al 2010, Franklin et al 2016, Salomón-Montijo et al 2016, Egert-Berg et al 2018, Goldshtein et al 2020, Aguilar-Romero et al 2022. Los frutos son bayas poliespermáticas de forma ovoide y semillas de color negro brillante (Turner et al 1995) con un promedio de 2000 semillas por fruto (Parker 1987).…”
