Figure 2.

Average cumulative germinations of experiment 2. Figure shows cumulative germination rates of wasabi seeds after conditioning in treatment solution: MQ (milli-Q water), MQ-KNaCl (milli-Q water containing K⁺, Na⁺, and Cl⁻), MQ-CaNaCl (milli-Q water containing Ca²⁺, Na⁺, and Cl⁻), BONB-KNaCl (bulk oxygen nanobubble solution containing K⁺, Na⁺, and Cl⁻), and BONB-CaNaCl (bulk oxygen nanobubble solution containing Ca²⁺, Na⁺, and Cl⁻). Error bars indicate standard errors. Data points without error bars indicate no standard error.
