Germination Response of Legume Seeds Subjected to Moist and Dry Heat

Abstract

Prescribed burning is used in southeastern USA to promote growth of leguminous plants which produce seed important as quail food. These seed are characterized by a hard seed coat and the ability to remain dormant but viable for a long time. This study was conducted to determine the effect of heat on germination of seed from several of these legume species. Seeds of 18 species and two varieties were subjected to moist and dry heat treatment. Moist heat increased germination in eight species and two varieties, and dry heat increased germination in seven species and two varieties.
