(a) Boxplot of the stages of development of the most advanced floret (F1) in central spikelets at the onset of floret death for different experimental conditions (experiments and treatments). The horizontal line within each box is the median, and the bottom and top of each box represent the 25th and 75th percentiles, respectively. Crosses correspond to the mean. The whiskers represent the 10th and 90th percentiles, respectively and the values outside this range are individual outliers (closed circles). (b and c) Relationships between the average (b) and the standard deviation (c) of the scores of floret F1 in central spikelets at the onset of floret death in each environmental condition analysed and yield achieved by the crop in those conditions (as indicator of resource availability). Environmental conditions were (i) high- and low-nitrogen levels in the microcrops (closed and open symbols, respectively) under irrigated (circles) or rainfed conditions (triangles), and (ii) high- or low-inputs (closed and open squares, respectively) in the field experiments.
