A Possible Ecological Relation Between Soil Disturbance, Light-Flash, and Seed Germination
Preview not available

Abstract

A connection is suggested between two well-known but hitherto unrelated phenomena: germination under field conditions of certain seeds following soil disturbance and germination in laboratory experiments of certain seeds following brief exposures to light. A light-flash mechanism for breaking dormancy is proposed as a possible adaptation aiding pioneer plants in exploitation of disturbed habitats.
