Question

Inflorescence in Solanaceae is:
A. Racemose
B. Cymose
C. Hypanthodium
D. Verticillaster

Answer 1

Hint:- This is a type of inflorescence flowering shoot in which, on the top of the flower stalk, the first-formed flower emerges from the growing area. Therefore, at the tip, no new flower buds can be developed and other flowers are formed from the lateral buds below

Complete step-by-step solution:- The inflorescence of the Solanaceae family species has usually been known as a cyme. Cymose in-florescences are usually characterised by unique growth in which the inflorescence meristem ends up in a floral bud, followed by the next floral meristem developing on the previous flower's flank. On a single side of the peduncle, the helicoid cyme produces floral buds, while the scorpioid cyme alternately produces floral buds on opposite sides of the peduncle.

Hence, Option B i.e.,Cymose is the right answer.

Additional Information:-
A raceme inflorescence does not end in a flower, unlike a cyme, but the inflorescence meristem remains indeterminate, and floral meristems are produced on the flank of the inflorescence meristem in a monopodial way. The earliest study identifying tomato inflorescences as cymose was based on unaided eye observation. Other studies have shown that the climate and (or) the genotype play an important role in deciding the composition of the cymose or racemose inflorescence.

Other than cymose and racemose, there are other types of inflorescence as well:
Hypanthodium: A cup-shaped structure with a cavity that has both male and female flowers and a narrow apical opening is created by the main axis.
Cyathium: Here, the cup-shaped structure is created from the bracts' involvement. The single female flower, which is surrounded by multiple stalked male flowers, is present in the centre.
Verticillaster: This inflorescence type is characteristic of opposite-leaved plants. It has two clusters of sessile flowers that grow from the leaves' two opposite axils. Each cluster has an arrangement of dichasal cymes.

Note:- Four major forms of cymose inflorescence exist:
- Monochasial cyme
- Dichasial cyme
- Polychasial cyme
- Cymose capitulum
