Germinación de semillas de Magnolia pugana (Magnoliaceae), especie endémica y en peligro de extinción del occidente de México

Abstract: <p><em>Magnolia pugana</em> es una especie endémica y en peligro de extinción localizada en el occidente de México, que se distribuye en bosques de galería en las barrancas del sur de Zacatecas y centro-norte de Jalisco. El objetivo de este trabajo fue conocer la viabilidad de las semillas e identificar los tratamientos para romper la latencia de semillas de esta especie. Se colectaron semillas de cuatro localidades, tres en Jalisco (Centro Universitario de Ciencias Biológicas y Agropecuarias… Show more

“…The viability is 80% for M. iltisiana, this result agrees with what was found in [77] where they obtained 80% of viable seeds in M. schiedeana. While the seeds of M. pugana registered 67% [76]. Reference [75] reported that in species of the same genus from southern North America it has an average of 50% viability, similar results are found in M. vallartensis and M. pacifica with 50% and 53% respectively (Figure 10).…”

“…Magnolia seeds have viability percentages ranging from 50-100% [74,75]. Different studies have shown a low percentage of germination because they can present different types of dormancy (including physical, chemical, mechanical, physiological and morphological) [76]. To eliminate dormancy and increase the percentage of germination and produce the greatest number of Magnolia seedlings, different pre-germination procedures have been applied [77][78][79][80].…”

“…Área de estudio: La zona de estudio comprende dos localidades en el municipio de Zapopan, Jalisco, México. La primera es una plantación en el Centro Universitario de Ciencias Biológicas y Agropecuarias (CUCBA) con coordenadas 20°44'53.6" -103°30'52.2" W, a una altitud de 1 659 msnm, la cual contiene 25 individuos adultos de Magnolia pugana que fueron plantados como brinzales en 1985, provenientes de semillas recolectadas de una población silvestre ubicada en las inmediaciones del poblado de San Lorenzo (8 km al Oeste del pueblo de Santa Lucia, Zapopan, Jalisco) (Jacobo-Pereira, Romo-Campos, & Flores, 2016). Los suelos predominantes son de tipo Regosol eútrico, los cuales se caracterizan por su pobre contenido en materia orgánica y una textura arenosa (Ibarra, Ruiz, González, & Flores, 2007).…”
