From: The development and geometry of shape change in Arabidopsis thalianacotyledon pavement cells

Age (DAG) Area (μm2) Perimeter (μm) Circularity Number of Skeleton Ends Growth Rate (%/hour)
2 (N = 41) 2169 ± 597 (1) 279 ± 66 (2) 0.35 ± 0.08 (3) 8 ± 2 (4)  
5 (N = 44) 3756 ± 1973 401 ± 175 0.30 ± 0.09 11 ± 4 1.02 ± 0.53(5)

  1. (1),(2),(3),(4) Mean ± SD
  2. (5) Mean ± SD, Growth rate from 2 DAG to 5 DAG
  3. (6) Growth rate from 5 DAG to 12 DAG
  4. (7) Growth rate from 12 DAG to 18 DAG
  5. The parameters of cell area, perimeter, circularity and number of skeleton ends are significantly different between 2 DAG and 5 DAG cells (t-test, p < 0.05). These parameters are significantly different between 5 DAG and 12 DAG cells as well (t-test, p < 0.05). These parameters are not significantly different between 12 DAG and 18 DAG cells.
