Fennel grooved. Fennel is widely cultivated, both in its native range and elsewhere, for its edible, strongly flavored leaves and fruits. Its aniseed flavor comes from anethole, an aromatic compound also found in anise and star anise, and its taste and aroma are similar to theirs, though usually not as strong. Florence fennel ("Foeniculum vulgare" Azoricum Group; syn. "F. vulgare" var. "azoricum") is a cultivar group with inflated leaf bases which form a bulb-like structure. It is of cultivated origin, and has a mild anise-like flavor, but is sweeter and more aromatic. Florence fennel plants are smaller than the wild type.
Flavour (particle physics) the eigenvalues of the various charge operators are conserved. Absolutely conserved flavour quantum numbers are: In some theories, the individual baryon and lepton number conservation can be violated, if the difference between them () is conserved (see chiral anomaly). All other flavour quantum numbers are violated by the electroweak interactions. Strong interactions conserve all flavours. If there are two or more particles which have identical interactions, then they may be interchanged without affecting the physics. Any (complex) linear combination of these two particles give the same physics, as long as the combinations are orthogonal, or perpendicular, to each other. In
