Table 7: Number of petri dishes from which Eriogonum floridanum (Polygonaceae) and Garberia heterophylla (Asteraceae) seeds germinated after being exposed to 100 or 25 for 5 minutes. Germination trials were conducted from December 8–17, 1993, and from December 14, 1995 to January 2, 1996 for Eriogonum and Garberia, respectively.

Seed species Temperature () Number of petri dishes(a) Eriogonum 25 4 100 0(b) Garberia 25 4 100 0(b)

Each petri dish contained 20 seeds. Fisher exact test showed a reduction in germination .
