Mycoflora in Exhumed Seeds of Opuntia tomentosa and Its Possible Role in Seed Germination
Figure 6
Micrographs of Opuntia tomentosa seeds exhumed after 5 months of burial and laboratory storage for 2 years. (a) Deep degradation of the funicular flanks in seeds buried at the open site, (b) cracks in the hilum-micropylar region, (c) degraded and eroded funicular envelope exposing the vascular bundles. C: cracks, Ff: funicular flanks, Fg: funicular girdle, HMR: hilum-micropylar region, Vb: vascular bundles.
