Fig 2.

Time course of changes in longitudinal length (a), dry weight (b), starch content (c), and relative value of starch content (d) in developing INT3 in two high-yielding rice cultivars in 2014. Yellow and light blue circles indicate H193 and MOMI, respectively. Data in a and b-d are the mean ± SEs (n = 30) and (n = 3) of field-grown plants, respectively. Significance at the 0.05, 0.01 and 0.001 probability levels is indicated with *, **, and ***, respectively. Note that there were substantial varietal differences in terms of both starch content (c) and the timing of starch accumulation (d).
