Mother Axis is the axis (stem) upon which the flowers are borne. Floral diagram: The symbol which is used to express the arrangement, number, symmetry. The diagram representation of the arrangement of floral leaves on the mother axis of flower is called floral diagram. Mother axis is drawn by a small circle (ii) Particular sign is used to express each whorl. Floral diagrams are a graphical means to describe the flower. Drawing of planes: The axis on Y1. placentation etc. Floral diagram - definition. Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Floral diagrams. Flower: Pedicillate; bracteate: actinomorphic cut from any axis; Regular; complete; hermaphrodite both sex organs are present on the same plant; mostly perigynous, … all the floral parts are drawn with respect to the position of this axis. Angiospermae flower (Figure 1A,B) presents leaves with different forms, sizes, colors, number and disposition. When the flowers are borne laterally upon it, the side of the flower towards the mother axis (or precisely towards the apex of mother axis) is known as the posterior side while the side away from it (the side of the flower towards the bract when it is present) is called as the anterior side. The floral leaves are arranged in stem axis in rosette; they are densely crowded upon one another. It is very. main axis or mother axis. useful for the study of flimers. @raja. the floral axis/mother axis is the peduncle(the stalk that bears the flowers). Each lateral flower has a DV axis with respect to the main axis and a bract. (D) The floral formula for Solanaceae is ⊕ K (5) C (3) G (2) . The sterile leaves form Distal free lobes of the calyx are lanceolate, 7-9 mm long and 4-5 mm wide and outwardly reflexed at an angle of [+ or -] 60[degrees] with the floral axis.Shallow depression-like glands are present on the ventral surface of the calyx (Fig. Reduced to a low ring or a fringe of scaly, bristly or hairy appendage on the rim of the floral axis and often persist on the ripe fruit, superior. [Left] Normal Streptocarpus flower ( zygomorphic or mirror-symmetric), and [right] peloric (radially symmetric) flower on the same plant Floral Diagram. ADVERTISEMENTS: ...

Some floral leaves are sterile and other fertile ones. (A) Schematic diagram of an inflorescence. hich flower is borne is called. FolloYy ing procedure is adapted to form a floral diagram: I. (C) In pea flower the stamens are monadelphous. These pictures show a cross-section (or cross-sections) of a young flower or a bud, they can be also defined as a view of the flower perpendicular to its axis. (C) Upper: typical arrangements of the outermost floral organs (sepals or outer tepals) with respect to the DV axis. (B) DV axis in an Antirrhinum majus lateral flower, corresponding to the DV axis of the pollinators. (B) The floral formula for Liliaceae is ⊕ P 3 + 3 A 3 + 3 G − 3 . The correct statements are of floral leaves of different whorls based on floral axis is said to be floral diagram. Rules of drawing: (i) It is drawn, on the basis of mother axis. The floral diagram is a diagrammatic representation of theoretical transverse section and ground plan of a floral bud in relation to the mother axis which lies at the posterior side.
