Pectic substances in tomatoes as related to whole-fruit firmness, and inheritance

Pectic substances in tomatoes as related to whole-fruit firmness, and inheritance

Proceedings American Society Hort Science 89: 528-531

The tomato varieties Tecumseh and Eastern States 24 differ significantly in pectic content of the fruit. Dominant genes are responsible for low pectic levels, and their principle effect is on the protopectin fraction. Pectic substances are correlated with whole-fruit firmness. Protoptectin contributes more to firmness than the water soluble pectic fractions.
