Question

Disadvantages of using artificial plant growth regulators

Answer 1

Answer:

Disadvantage of artificial plant hormones :

Plants are continuously exposed to a myriad of external signals such as fluctuating nutrients availability, drought, heat,/cold, high salinity, or pathogen/pest attacks that can severely affect their development, growth, and fertility.

Answer 2

Disadvantages of artificial plants growth:

• Plants are continuously exposed to a myriad of external signals such as fluctuating nutrients availability, drought, heat/ cold, high salinity or pathogen/pest attacks that can severely affect their development, growth, and fertility.
• Hormones are produced naturally by plants, while plant growth regulators are applied to plants by humans.
• Plant hormones and growth regulator are chemical that affects:

                                Flowering

                                Aging

                                Root growth

                                Distortion and killing of organs

                                Prevention or promotion of stem elongation

• Very small concentrations of these substances produces major growth changes.
• The increased ethylene in leaf tissue in the fall is part of the reason leaves fall off trees.
• High concertation ABA in guard cells during periods of drought stress probably play a role in stomatal closure.
