Pedicel is also called flower handle.solitary flowerBranchlets bearing each flower in a stalk or inflorescence[1]。It supports the flowers and makes them locate in a certain space;At the same timestemA passage connected with flowers.
The length of flower stalks varies with plant species, and there are flowers without flower stalks.The pedicel is unbranched or branched, and the branched pedicel is called peduncle.
A twig that grows under each flower.On the one hand, it supports the flowers and makes them unfold in all directions;on the other handdrawNutrition, transporting various substances from stems to flowers.It is green, and different plants have different pedicels.
Pedicel is also calledPetioleIt is a flower bearing twig, which can spread flowers on prominent positions of branches;At the same time, it is also a short handle connecting the flower and the stem.The pedicel may be long or short, depending on different plant species, such as verticilliumBegonia(Malus halliana) has a long pedicel, whileQuince(Chaenomeles speciosa) has very short pedicels, and some plants have no pedicels.The pedicels are branched and unbranched.Branched pedicels are called peduncles, with a flower on the top.The structure of pedicel and stem are the same.

The pedicel and stem have the same structure.The periphery of pedicel is epidermis, and the basic tissue is in the epidermis, with vascular bundles distributed.The vascular bundles of dicotyledonous plants are mostly of infinite outer toughnessCircular arrangement。Monocotyledons are of limited external toughness, and they are scattered.The pith of pedicel is generally more developed than that of stem.The pedicels of some dicotyledons can also undergo temporary secondary growth.
The structure of inflorescence axis and total pedicel is similar to that of pedicel.[2]

The receptacle is the top part of the pedicel, which is generally slightly enlarged. Other parts of the flower are arranged on the top in a certain way, from outside to inside (or from bottom to top)calyx, corolla, stamen group and pistil group.
ReceptacleThe following part is calledPetiole。The flower stalk is the twig of each flower.On the one hand, it supports the flowers and makes them unfold in all directions;On the other hand, various substances are transported from stems to flowers.Different plants have different flower stalks, also called pedicels.
The pedicel is the total flower handle, and the pedicel is the short handle connecting the flower and the stem. That is, several small flowers of some plants grow on one total flower handle. This total flower handle is called the pedicel.Of course, some people call the flower handle pedicel.
Stems generally refer to the aboveground parts of plants, on which leaves or branches grow.The structure of pedicel and stem are the same.The difference is just the connection of flowers.Some pedicels can also branch, and the branched pedicel is called peduncle, so the pedicel is also jointed.
