The cabbage inflorescence, which appears in the plant's second year of growth, features white or yellow flowers, each with four perpendicularly arranged petals. Cabbage seedlings have a thin taproot and cordate (heart-shaped) cotyledons. The first leaves produced are ovate (egg-shaped) with a lobed petiole.
In biology, the BBCH-scale for leafy vegetables forming heads describes the phenological development of leafy vegetables forming heads, such as cabbage, chinese cabbage, lettuce and endive, using the BBCH-scale. The phenological growth stages and BBCH-identification keys of leafy vegetables forming heads are:
Brassicaceae (/ ˌ b r æ s ɪ ˈ k eɪ s iː ˌ iː,-s i ˌ aɪ /) or (the older) Cruciferae (/ k r uː ˈ s ɪ f ər i /) [2] is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs.
Brassica oleracea is a plant species from the family Brassicaceae that includes many common cultivars used as vegetables, such as cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, Savoy cabbage, kohlrabi, and gai lan. It was most likely first brought into cultivation in the Eastern Mediterranean region.
In botany, an umbel is an inflorescence that consists of a number of short flower stalks (called pedicels) that spread from a common point, somewhat like umbrella ribs.The word was coined in botanical usage in the 1590s, from Latin umbella "parasol, sunshade". [1]
An inflorescence, in a flowering plant, is a group or cluster of flowers arranged on a 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]
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.
With larger Fibonacci pairs, the pattern becomes complex and non-repeating. This tends to occur with a basal configuration. Examples can be found in composite flowers and seed heads. The most famous example is the sunflower head. This phyllotactic pattern creates an optical effect of criss-crossing spirals.
