However, in some cases, it has been found the exudate causes the growth of certain endophytic bacteria, whose function is unknown. In them there is only one kind of scales, bracts polleniferous (carrying the pollen ), have millions of pollen grains.Corymb is a type of inflorescence open racemosa or racemose in which the axis is short and the pedicel of the flowers are long and out at different heights of the shaft. Typically, it is poorly developed, so that libraries stand widely, in some angiosperms primitive, all the yarn may be more or less connective foliaceus and can reach a great development, so widely separated libraries . The length of each floral pedicel is such that all the flowers of the corymb open at the same level.In plants, gymnosperms and non-flowering plants there are no real fruit, although in the case of pines, many people take the cones and fruit. In some cases the connective appendages presents a variety of ways that have systematic importance (eg in the Melastomataceae ).Some species based on a heterogeneous inflorescences corymb, for example a corymb of chapters in Achillea .
The term colter ????a comes from the Greek (tail) and the ending-ether as in ureter.The female cones are called cones on the pines and other Pinaceae (family Pinaceae ), but may have other names and appearance in different conifers, so called glbulas in the cypresses , and arcstidas in the junipers and the junipers , members of the Cupressaceae family ( Cupressaceae ). In the pines in Mediterranean climates or semiarid, fire causes that process, encouraging the repopulation after the fire.Cone (Conus) is the Latin name that was used to designate what in Spanish is called pineapple. The sporangiophores are peltate (with stand), non-photosynthetic. Its position favors the dispersion of pollen in conifers is transported by wind ( anemophily ).The axis of the strobilus may be green or not green, and never branched.After fertilization, they form seeds ( pine nuts ). Examples of species with inflorescences are corymb pear ( Pyrus ) and cherry ( Prunus ). As the eggs are not enclosed in an ovary, the seeds are not hosted in a fruit. The bodies which are connate histological continuity exists, ie tissues that form such bodies are also fused.
They lack vascular bundles . These eggs are not enclosed in an ovary (Greek; gimnos = naked sperma = seed).. For example, leaves joined at their bases opposite the filaments of the anthers or members of the cup or corolla may be free (ie, Ultrasonic Processing Manufacturers separated from each other) or connate (ie, joined together).The male cones are always much smaller than the female, and are grouped around the ends of branches on the end of the year growing shoots.In Botany , are said connate bodies are more or less united.The colleters can be of various types:Standard or Type S : hair-like clavate;dendroide or type D : looking branched, andpenicilado or type B : brush-like.In Equisetum strobili at the end of the fertile branches. Each scale bears one to several eggs, depending on species. These are interpreted as megasporofilos (leaves bearing megaspores) and seminal primordia they appear, that after pollination and subsequent fertilization , must become seeds. for example.
They act as additional protective zone with meristematic tissues.In Botany, is called colter to a secretory multicellular structure, comprising a core surrounded by a parenchymatous or two layers of epidermal cells, cells taken from the outer layer a columnar arrangement (palisade). Many prefer to restrict the use of the term to the original meaning, or at least to the biological group of conifers (division Pinophyta ), though also including male structures. In the case of Equisetum fertile leaves are called "sporangiophores", and usually not llamrselo strobilus cone as in conifers. With the maturing of pineapple tectrices bracts (usually the only visible in the cone closed) should be deployed, what they do sometimes abruptly, causing violent solution and seed dispersal., in the scales that cover the buds overwintering of the species of the genus Aesculus (horse chestnut), in stipules of some Rubiaceae , on the edges or the limbo leaf in the bracts , bracteoles , calyx and corolla flowers of other angiosperms .
The female cones are formed by a central axis which many spirally placed scales.In the pines and genders coming seminfera Flake can come off with the seed, acting as a wing that favors a dispersion anemocorous .In botany , called connective tissue portion of the sterile anther situated between the libraries , integral with them and holds them together. They usually take emergency aspect (trichomes), narrowed basally (with clavate appearance), often in groups or tufts located in different parts of some plants, p.Conifers are gymnosperms that produce seeds in cone-shaped structures. In this broader sense cone is synonymous with strobilus , a term generally preferred in the scientific literature. Sporangiophores are shaped pulvinus young and then take a hexagonal shape (given surface) because the mechanical force exerted between them. Are arranged around the axis of helical shape and initially tightened thick scales, called bracts tectrices (carriers), on each of which are located one or several bracts seminiferous. To do this, the product of secretion, mucilage , as well as polysaccharides , proteins containing various protective enzyme action, such as chitinases , -1 ,3-glucanase and polyphenol oxidases , which can damage the chemical components of microorganisms attackers.In Botany a cone or strobilus is a structure based on a terminal shaft, around which are deployed reproductive leaves with a generally helical.
