In most species that produce a determinate inflorescence in this way, all of the flower buds are formed before the first ones begin to open, and all open more or less at the same time. In some species with determinate inflorescences however, the terminal flower blooms first, which stops the elongation of the main axis, but side buds develop ...
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 and by the timing of its flowering (determinate and indeterminate). [2]
Arranged on a conical surface (like a snail shell); used to describe inflorescence s in which the bud s are arranged in an almost helical manner on the outside of a long, tapering, conical rachis. bract A modified leaf associated with a flower or inflorescence and differing in shape, size, or color from other leaves (and without an axillary bud ...
ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
In mathematics, the determinant is a scalar-valued function of the entries of a square matrix.The determinant of a matrix A is commonly denoted det(A), det A, or | A |.Its value characterizes some properties of the matrix and the linear map represented, on a given basis, by the matrix.
This type of inflorescence is called spikelet. The flowers can be hermaphrodites or unisexuals and present a rudimentary perianth of 2 or 3 pieces, the lodiculae or glumellulae. These lodicules are the organs that, when they become turgid, determine the opening of the antecio or floral box during flowering, allowing the feathery stigmas and the ...
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.
The bicolor unit consists of an ordered inflorescence with determinate cymose structures. The inflorescence can branch off the main axis, creating separate orders of the flowers, with the main axis developing first. Bracts on the peduncle subtend axillary buds that become these lateral stalks. One bract within this whorl is a sterile bract.
