Fig. 1. Dynamics of silk exsertion in apical and subapical ears of Asgrow 740 as influenced by plant population density. Symbols are the number of exposed silks per ear and lines are corresponding monomolecular functions fit to the data. Parameters SN, b, to and duration in Eq. [4] to predict silk emergence from subapical ears of P3925 were generated from these curves (see Table 1). Vertical lines are standard errors for five plants. Plants grown at 16 plants m-2 did not produce a second ear.
