NFFc, number of fertile florets in the central spikelet; NIFc, number of initiated florets in the central spikelet; FSc, floret survival in the central spikelet; RFIc, rate of floret initiation in the central spikelet; DFIc, duration of floret initiation in the central spikelet. * For RFIc, R2 of all regressions from which slopes were calculated were greater than or equal to 0.72.
