In botany, an inflorescence is a group or cluster of flowers arranged on a plant's stem that is composed of a main branch or a system of branches. [1] An inflorescence is categorized on the basis of the arrangement of flowers on a main axis ( peduncle ) and by the timing of its flowering (determinate and indeterminate).
In reference to an inflorescence (a shoot specialised for bearing flowers, and bearing no leaves other than bracts), an indeterminate type (such as a raceme) is one in which the first flowers to develop and open are from the buds at the base, followed progressively by buds nearer to the growing tip. The growth of the shoot is not impeded by the ...
The meristem can be defined as the tissue or group of plant tissues that contain undifferentiated stem cells, which are capable of producing any type of cell tissue.Their maintenance and development, both in the vegetative meristem or the meristem of the inflorescence is controlled by genetic cell fate determination mechanisms.
In botany, infructescence (fruiting head) is defined as the ensemble of fruits derived from the ovaries of an inflorescence. It usually retains the size and structure of the inflorescence. [1] In some cases, infructescences are similar in appearance to simple fruits. These are called multiple fruits.
When plants begin flowering, the shoot apical meristem is transformed into an inflorescence meristem, which goes on to produce the floral meristem, which produces the sepals, petals, stamens, and carpels of the flower. In contrast to vegetative apical meristems and some efflorescence meristems, floral meristems cannot continue to grow indefinitely.
Multiple fruits are formed from the fused ovaries of multiple flowers or inflorescence. [1] An example of multiple fruits are the fig, mulberry, and the pineapple. [1] Simple fruits are formed from a single ovary and may contain one or many seeds. They can be either fleshy or dry.
When pollination is zoophilous flowers can be fragrant and attract large numbers of pollinator-collecting bees to congregate around the inflorescence and take advantage of this new and abundant source of pollen. After anthesis massive die-offs of all sister groves occur within three years of each other and can have devastating effects.
In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. [1] A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees.
