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) baryon number . They also all carry weak isospin, . The positive- quarks (up, charm, and top quarks) are called "up-type quarks" and negative- quarks (down, strange, and bottom quarks) are called "down-type quarks". Each doublet of up and down type quarks constitutes one generation of quarks. For all the quark flavour quantum numbers listed below, the convention is that the flavour charge and the electric charge of a quark have the same sign. Thus any flavour carried by a charged meson has the same sign as its charge. Quarks have the following flavour quantum numbers: These five quantum numbers,
