Etiología de las pudriciones en el tallo de Hylocereus costaricensis, provocadas por Enterobacter hormaechei, en Costa Rica

Abstract: En el 2011 se realizó una investigación para identificar el agente causal de las pudriciones presentes en los tallos de Hylocereus costaricensis en Costa Rica. En época lluviosa, la sintomatología asociada a estas enfermedades correspondió a pequeñas pudriciones amarillentas que por lo general iniciaron del borde del cladodio y se extendieron hacia adentro del mismo, hasta que se descompuso todo el tallo. Durante la época seca, se observaron manchas circulares anaranjadas que posteriormente se tornaron de colo… Show more

“…Currently, there are conflicting reports regarding the pathogens responsible for stem rot in China. Several fungi, including Enterbacter sp., Bipolaris cactivora, Neoscytalidium dimidiatum, Fusarium semitectum, F. oxysporum, and F. moniliforme are speculated to be the major contributors [8,[14][15][16]. Establishing pathogen identification is essential for effective disease management for both farmers and plant caretakers.…”

“…The main consumption of Hylocereus is as fresh fruit, but the flowers and tender shoots are also consumed as fresh vegetables and its potential for cultivation is expanding due to strong demand in the industrial, food technology and pharmaceutical areas. Within the industrial market, various authors (Esquivel & Araya, 2012;Woo et al, 2011;Wong & Siow, 2015), pointed out the importance of pitahayas for their betalains, especially betanins as a natural food colorant, and pectin as a good quality thickener, as well as a colorant in the cosmetology industry (Le Bellec, 2004;Retana-Sanchez et al, 2019). Al-Alwani et al, 2017, replaced the use of silicon with pitahaya dye to fabricate solar cells and to generate a low-cost and environmentally-friendly sensitizer.…”

“…atroseptica (hoy Pectobaterium atrosepticum, Gardan et al, 2003) en tubérculos de papa (Herrera & González, 1977) mientras que, en el año 1979, se identificó E. chrysanthemi en el cultivo de piña como causante de BSR (Chinchilla et al, 1979). Recientemente, se identificó la bacteria Enterobacter hormaechei como posible agente causal de la pudrición blanda en los tallos de pitahaya (Hylocereus costaricensis) (Sánchez et al, 2019). No obstante, en ninguno de estos estudios se han realizado análisis moleculares detallados de los agentes causales con el fin de confirmar su identificación.…”
