In botany, apedicel is a stalk that attaches a singleflower to theinflorescence. Such inflorescences are described aspedicellate. The stalk at the base of a leaf is called apetiole.
Pedicel refers to a structure connecting a single flower to its inflorescence.[1] In the absence of a pedicel, the flowers are described assessile. Pedicel is also applied to the stem of theinfructescence. The word "pedicel" is derived from the Latinpediculus, meaning "little foot".[2] The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called apeduncle.[3] A pedicel may be associated with abract or bracts.[4]In fruit-bearing plants such as pears (Pyrus species), differences in pedicel length, diameter, and tissue composition influence fruit size, firmness, and sugar content.[5]
In Halloween types ofpumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".[6]
