What is a acropetal succession?
Acropetal succession refers to the arrangement of flowers, where the older flowers are present at the base and younger flowers are present at the apex. In the centripetal succession, the younger flowers are present at the centre and older flowers are present towards the periphery.
What is called inflorescence?
inflorescence, in a flowering plant, a cluster of flowers on a branch or a system of branches. 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).
What is Hypanthodium inflorescence?
Hypanthodium inflorescence is best defined as a fleshy receptacle which leads to the formation of a hollow cavity featuring an apical opening known as the ostiole. The flowers develop towards the inner wall of the hollow cavity.
What is acropetal and Basipetal succession?
Acropetal order(modified form of racemose inflorescence)refers to the arrangement of flowers on the pedicel that the new flowers and buds are at the apex and the older flowers are at the base whereas vice-versa is for basipetal order which is a modified form of cymose inflorescence (i.e new flowers are at the bottom …
What is acropetal and centripetal succession?
Acropetal succession: It is a modified form of racemose inflorescence in which the older flowers are at the base and younger ones are at the apex. Centripetal succession: It is a modified form of racemose inflorescence in which the peripheral flowers mature first and then maturation proceeds towards the centre.
What is the role of inflorescence?
Inflorescences are complex structures with many functions. At anthesis they present the flowers in ways that allow for the transfer of pollen and optimization of the plant’s reproductive success. During flower and fruit development they provide nutrients to the developing flowers and fruits.
Why is inflorescence important?
Background: Inflorescences are complex structures with many functions. At anthesis they present the flowers in ways that allow for the transfer of pollen and optimization of the plant’s reproductive success. During flower and fruit development they provide nutrients to the developing flowers and fruits.
What is capitulum in biology?
capitulum An inflorescence that consists of closely packed flowers or florets which have no stalks and arise on a flattened axis, all at the same level. The capitulum is surrounded or subtended by an involucre of bracts giving it the appearance of a single flower. Capitula are typical of the Compositae.
What is acropetal and Basipetal order?
¿Cuál es el eje de la inflorescencia cimosa?
El eje de la inflorescencia presenta un crecimiento indefinido, y en las regiones laterales ocurre la producción de yemas florales, que abren progresivamente. En el caso de las cimosas todas las flores son terminales. Si observamos la apariencia de las inflorescencias cimosas nos pueden parecer bastante similares a las racimosas.
¿Cuál es la terminología de las inflorescencias?
Desde el año 1944, en una revisión realizado por Rickett (ver referencias), quedó claro que la terminología relacionada con las inflorescencias es confusa. Morfológicamente, una distinción principal entre las inflorescencias es la manera en que termina el eje. Esta clasificación tiene dos categorías o tipos: monotelas y politelas.
¿Por qué las inflorescencias tienen un aspecto compacto?
La mayoría de las inflorescencias presentan un aspecto compacto, ya que es normal que las regiones de los entrenudos no experimenten un alargamiento significativo durante el desarrollo. Aloe hereroensis. Generalmente estas mejoran el éxito reproductivo de la planta, si las comparamos con una única flor.
¿Qué son las hojas de las inflorescencias?
– Las hojas de ambas estructuras son diferentes. En las inflorescencias encontramos hojas muy heterogéneas, en términos del tamaño, la forma y la coloración. Estas hojas modificadas se denominan brácteas (mencionadas anteriormente), y son hojas que ayudan a proteger a las flores.
