Question

Which of the following attributes can be improved in ornamental plants?

• A. Regulation of flowering
• B. Weed control
• C. Promotion of vegetative growth
• D. All of the above

Answer 1

The correct option is D All of the above

Ornamental plants are known for the decorative purposes in gardens and landscape design projects, as houseplants, for cut flowers and specimen display.

The regulation of flower can be improved in ornamental plants through physical alteration of day length or modification of hormone biosynthesis and metabolism.

Weeds can be controlled by resistance to a broad spectrum herbicide like glyphosate which would allow the protection of young plants from weed seedlings in new areas and prevent damage from spot- spraying of weeds in established beds.

The vegetative growth of the ornamental plants can be promoted by using various growth regulators.

So, the correct answer is option D.
