Effects of Soil Temperature during Fire on Seed Survival in Florida Sand Pine Scrub

Table 7

Number of petri dishes from which Eriogonum floridanum (Polygonaceae) and Garberia heterophylla (Asteraceae) seeds germinated after being exposed to 100^∘C or 25^∘C 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 (^∘C)	Number of petri dishes^(a)(𝑛=4)
Eriogonum	25	4
	100	0^(b)
Garberia	25	4
	100	0^(b)

(a)Each petri dish contained 20 seeds.
(b)Fisher exact test showed a reduction in germination (𝑃=.0143).
