The etymology from inflorescence takes us to the Latin word inflorescens, in turn derived from inflorescĕre (which can be translated as “Cover yourself with flowers” ). The concept is used in the field of botany to refer to the arrangement of flowers in a plant .
Remember that one plant It is an autotrophic living being that has no locomotive capacity. The flowers On the other hand, they are buds composed of colored leaves: they are reproductive structures that produce seeds.
The inflorescence is the distribution of flowers on the tip of a stem or on the branches. There are inflorescences of a single flower (called unifloras inflorescences ) and others with two or more flowers (the pluriflora inflorescences ).
In the case of uniflora inflorescences, they can be axillary inflorescences or of terminal inflorescences . Pluriflora inflorescences differ between simple and the composed (according to the existence, or not, of a axis common) and between cimosas or closed (which have definite growth) and clustered or open (of indefinite growth).
While simple inflorescences can be described as a common axis that has uniflora branches when the main axis has lateral plurifloras. According to the form and the developing from this axis, we can distinguish between the clusters and the cimosas. The two types can consist of elementary inflorescences such as a cluster that groups other clusters or a spike with several spikes (in this case we talk about homogeneous inflorescence ).
If, instead, they are made up of elements of a different nature, we can distinguish two groups: if they are of the same type, they are called heterogeneous inflorescences ; in the opposite case, they are called mixed inflorescences . When the pluriflora looks like one flower , as in the chapter of the compounds, they are known as pseudo.
Returning to clusters or open, it is a type of inflorescence in which the meristems of the tips of the axes do not alter their activity along their increase . In addition, all its flowers grow on its sides and its spine develops indefinitely. In the case of cystic inflorescenics, on the other hand, flower production consumes the apical meristems of the axes.
The special inflorescences , on the other hand, are rare. In this type of inflorescence, the branching of the floral axis does not show a Pattern particular.
In short, the inflorescence can be understood as a system which has a main axis called spine , which usually leads bracts (special feature sheets); flowers arise in the armpits of the bracts. The spine, in turn, is linked to the stem of the plant through the peduncle ; a pedicel Meanwhile, hold each flower.
There are certain well-defined differences between the inflorescences and the remaining part of the vegetative stem, among which we can highlight the following:
* its growth is limited and its life ends when it has been able to reproduce, while the vegetative stem grows unlimitedly;
* usually the yolks Inflorescence is transformed into branches, which is why it is very common to exhibit complex ramifications. The buds of the vegetative stem, however, do not undergo any change;
* There are differences between its leaves, both in its color, its shape and size. The name they receive is bracts, mentioned above, and have the function of protecting the reproductive branches;
* he weather that it takes the inflorescence to complete its branching is much less;
* Inflorescences have elements such as branches or stems with leaves that give flowers in their armpits. The stem is called the axis of the inflorescence, and can give rise to other axes.
