Mycoflora in Exhumed Seeds of Opuntia tomentosa and Its Possible Role in Seed Germination
Applied and Environmental Soil Science, Volume 2011, Issue 1, 2011., 2011 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 ...
