a
Aborted ovules were counted in the 10th to 12th siliques of the main inflorescence of the indicated genotype at a stage when the final silique size was reached.
b
Aborted pollen were counted after Alexander staining of released pollen from the denoted genotype. In this assay, aborted pollen grains stain green.
