Dynamics of specific leaf weight (a, b) as function of developmental stage in 2019 and 2020, respectively. Each data point represents the mean ± SD (n = 3). Within the same panel, means not sharing a common letter indicate significant differences at P < 0.05. PS: peak squaring; FF: first flowering; FB: flowering and boll setting; FBO: first boll opening; MC0: no mepiquat chloride application; MC1: mepiquat chloride application; D1: plant density of 2.25 plants·m−2; D2: plant density of 4.5 plants·m−2; D3: plant density of 6.75 plants·m−2. The same as below
