Resumen
We evaluated the effect of cold storage and fire-related
cues on seed germination of Arctostaphylos pungens HBK (Mexican
Manzanita), a common shrub in poorly managed pine-oak forests
in Durango, Mexico. Because this shrub has a high density in previously
burnt forests, we investigated the effect that high temperatures,
smoke and charcoal might have on seed germination of this species.
Seeds were collected fresh from the shrubs. The highest germination
was 30% for seeds that had been cold stored, heat shocked, past
through smoke and watered with diluted charcoal.
