Fig. 2 Percent germination of CF₄-treated and untreated control seeds of radish (Raphanus sativus) and two cultivars of pea (Pisum sativum cv. Little Marvel, P. sativum cv. Alaska). Control seeds were under vacuum pressure for 24 h. Treatment main effects were significant (P = 0.009) for radish on Day 1 and for pea cv. Little Marvel (P = 0.03) on Day 3. All other treatment effects were not significant at P < 0.05
