Question

What is the vegetative propagule in dahlia??️️​

Answer 1

Sugarcane is propagated by stem cuttings known as aerial stems. ... These stems form a new plant when get detached from the parent plant. The vegetative propagation of dahlia is done by tuberous roots. Tuberous roots have abundant storage of reserved food material.

Answer 2

Answer:

PROPAGATION of. DAHLIA

Explanation:

Dahlia plants can be easily propagated in several ways: division of root system, cuttings, and from seed. Division of the root system and cuttings have the advantage of reliably reproducing the same flower that had been produced by the parent plant.

Propagation From Seed:

Dahlias hybridize readily; flowers of hybrids can be radically different from the flowers produced by the parent plants. So propagation from seed can result in unexpected results when it comes time for blooms. Easy hybridization has a positive aspect: a wide variety of flower forms and colors can be produced by dahlia plants, and new varieties are constantly being developed. Dahlia hybridizers work tirelessly (not to mention their plants) to develop some really spectacular flowers - great new varieties are introduced every year. The negative aspect of easy hybridization is that seeds will not relaibly produce flowers similar to the parent plant. In some cases exciting new flower varieties will result. But in most cases the flowers will not be as spectacular as the parent plant. So if you want the excitement of growing brand new varieties - plant seed, you will get interesting if not spectacular results. But if you want to know what kinds of blooms you'll be getting, it's best to propagate by division or cuttings.

Propagation by Division of Root System:

During the growing season a number of "tubers" will develop in the soil surrounding a dahlia's stems; the tubers are a part of the plant's root system. The tubers can be separated from the root system and re-planted to produce new plants the following season. The plants which emerge from the tubers will be "clones" of the parent plant - not hybrids. So they will produce flowers that are identical to the flowers of the parent plant. For the most part the plants grown at the farm come from tubers or cuttings - because there's just not a lot of room to experiment with hybrids here. (but if we had a spare acre or two there'd be some hybridizing going on)
