Table 3. Pollen viability in the wild-type (3037) and mutant (sd37) plants.

Pollen viability	3037	sd37
Stained pollen	95.4% NS	93.7%
In vitro germinated pollen	61.2% NS	58.5%

Data are shown as the mean ± SD (N = 100). Each of the parameters was compared between 3037 and sd37 using the Student's t-test.
