Pollen Viability & Seed Set
Seed set in tomato as a result of pollination with pollen of varying quality.
Pollen viability measured on the Ampha Z32 before pollination: A = 31%, B = 3.5% and C = 0.3%. The size of fruits resulting from pollinations with these pollen samples (pictures), as well as the seed set (graph below) correlate with the pollen viability.
Other species show similar behavior, although each species has individual correlation patterns.
