Table 6. Cell sizes and volume of anther cells in T. controversa infected anthers. X-axis indicates the cell width, Y-axis cell length, and Z-axis cell depth of epidermis (EPI), endothecium (EN), secondary parietal cell (SPL), middle layer (ML), tapetum (TA), pollen mother cell (PMC), microspore (MP) and pollen grain (PG). Cell volume obtained by multiplication of X, Y and Z-axes. Asterisks* indicate statistically significant differences. (Student’s t-test :*P  ≤ 0.05, **P  ≤ 0.01). The values without Asterisks* indicated the statistically non-significant. ± showed the standard error. – indicated that cells not appeared.
