In botany, phyllotaxis (from Ancient Greek φύλλον (phúllon) 'leaf' and τάξις (táxis) 'arrangement') [1] or phyllotaxy is the arrangement of leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. The basic arrangements of leaves on a stem are opposite and alternate (also known as spiral).

Son aquellas hojas que están dispuestas espacialmente sobre un eje (rama) en un solo plano y formando dos filas verticales; en las cuales las hojas pueden disponerse en forma alterna u opuesta.

Sep 11, 2017 · In this Primer I will give a broad overview of phyllotaxis, its emergence from the shoot apical meristem, how auxin and its transporter function as a ‘pattern generator’, and the role of tissue mechanics and computational modeling.

Filotaxia é o padrão de distribuição das folhas ao longo do caule das plantas. Informações sobre a filotaxia de uma espécie podem ser úteis na identificação de sua família botânica. [1] A distribuição das folhas pode apresentar as seguintes organizações básicas:

Phyllotaxis, the regular arrangement of leaves or flowers around a plant stem, is an example of developmental pattern formation and organogenesis. Phyllotaxis is characterized by the divergence angles between the organs, the most common angle being 137.5°, the golden angle.

Feb 7, 2021 · Phyllotaxis (phyllotaxy) is the arrangement of repeated plant organs. The word “phyllotaxis” itself was coined by Carl Friedrich Schimper (1830), a botanist and naturalist from Mannheim, Germany. It is a combination of two Greek …

Feb 27, 2019 · Here we propose a unified rule of phyllotaxis to explain both types of arrangement: the developed leaves form vertical rows along the stem. In the non-spiral arrangement, nascent to developed leaves always follow this rule, so that the number of leaf rows is kept constant irrespective of stem growth.

Jun 30, 2021 · Phyllotaxis, the regular arrangement of leaves or flowers around a plant stem, is an example of developmental pattern formation and organogenesis. Phyllotaxis is characterized …

En botánica, se llama filotaxis o filotaxia a la disposición de las hojas, brácteas, flores u otras estructuras vegetales repetitivas de forma regular, alrededor de un eje o centro, a menudo dispuestas según uno o varios sistemas de espirales o hélices.

Neste artigo, trazemos os principais tipos de filotaxia encontrados nas plantas vasculares, juntamente com uma breve descrição e imagens para a identificação dos mesmos. Entre os órgãos vegetativos das plantas vasculares, as folhas são as …
