Question

3. Write 2 ways in which new plants growing from dahlia roots is useful.​

Answer 1

Answer:

must maintain attachment to at least one "eye". The eye is the part of the tuber which will become the stem of the new plant; without an eye the tuber will not produce a plant.

Dahlias can be propagated from seeds, tubers, or cuttings. Seeds will produce varieties different from the parent plants, so propagation from seeds is used primarily to develop new cultivars.

The dahlia is a dicotyledon and, like other dicotyledon plants, features roots that are not dependent on a single, central root or taproot. The roots are so independent that you can reproduce a daughter plant by cutting away a portion of the roots of an adult plant in a process called division.

Answer 2

Answer:

Cuttings, seeds, and tubers can all be used to grow more dahlias.

Seed propagation is employed largely to create new cultivars since seeds will yield variants that differ from the parent plants.

Explanation:

Dahlia:

• Native to Mexico and Central America, dahlias are a genus of bushy, tuberous, herbaceous perennial plants.
• Its garden relatives, which belong to the dicotyledonous Compositae family, are the sunflower, daisy, chrysanthemum, and zinnia.

Propagation of plants:

• Asexual propagation is mostly accomplished through cuttings, layering, division, budding, and grafting.
• Cuttings entail rerooting a piece of the parent plant that has been cut off; layering entails rerooting and then severing a bit of the parent; and budding and grafting entail uniting two plant parts from different types.
