Fig. 4From: No evidence of flowering synchronization upon floral volatiles for a short lived annual plant species: revisiting an appealing hypothesisDescribes the relationship between the number of open flowers and time that results in a sigmoid curve. The three parameters describe the upper asymptote (Asym, blue), the x-intercept of the inflection point (xmid, red) and the steepness (scal, grey) of the sigmoid curveBack to article page
