Effect of the parameters 𝛽 and 𝛽₀ from (2) on the fertilization kinetics for a constant value of 𝑆₀ (1,000/μL) and increasing values of 𝑂₀ (1, 2,…,6/μL). (b) Parametric values (𝛽=3.8×10⁻⁶; 𝛽₀=3.3×10⁻⁴ mm³·s⁻¹) from Vogel et al. [27]; at left and right, results of dividing by 4 the value of 𝛽 and multiplying by 4 the value of 𝛽₀, respectively.
