Advantages of vivipary in Echinocactus platyacanthus , an endemic and protected Mexican cactus species

Stimulatory and inhibitory effects of light on Cereus repandus (Cactaceae) seed germination are strongly dependent on spectral quality

“…However, less is known for light-responsive cactus seeds about the spectral requirements for the trigger, which has implications for understanding of the importance of nurse plants, and shading, in the natural regeneration process in cacti (Ordoñez-Salanueva et al, 2015). This specific requirement for light might also serve to stop the seed from germinating within the developing fruit before endozoochorous dispersal (Flores et al, 2011), although this is not the case in all cacti as vivipary has been reported for at least 53 species (Cota-Sánchez, 2004; Cota-Sánchez et al, 2011; Aragón-Gastélum et al, 2017).…”

Germinación y crecimiento de Echinocactus platyacanthus Link & Otto (Cactaceae)

“…Los reportes sobre germinación para la especie E. platyacanthus, se basan mayormente en la aplicación de tratamientos pre-germinativos, por ejemplo, mediante el empleo de ácidos fuertes (Rosas López, 2002); (Navarro et al, 2014), por inoculación con Bacillus spp., Trichoderma spp., Glomus intraradices y Rizobacterias haloficas (Castillo Reyes et al, 2014), usando semillas provenientes de la defecación de ganado caprino (Baraza & Fernández-Osores, 2013), mediante ciclos de hidratación y deshidratación (Contreras Quiroz et al, 2016); o con el uso de semillas vivíparas (Aragón-Gastélum et al, 2017).…”
