Abstract EN
The funicular cover of the Opuntia tomentosa seed limits imbibition; germination occurs only when the funicle is weakened or the funicular valve is removed.
We investigated the role of fungi in funicular weakening and seed germination.
Seeds that had been either buried in one of two sites or stored in the laboratory were germinated with and without a valve.
Disinfected or nondisinfected seeds and their naked embryos were cultivated on agar or PDA.
None of the 11 identified fungal genera grew on the disinfected control seeds or the embryos.
The mycoflora present on disinfected and nondisinfected exhumed seeds suggest that the fungal colonization occurred in the soil and differed between the burial sites.
Exhumed seeds with and without a valve germinated in high percentages, whereas only the control seeds without a valve germinated.
Scanning electron micrographs showed that the hyphae penetrated, cracked, and eroded the funicular envelope of exhumed seeds.
