Question

Gibberellins take part in:
A. Bolting of rosette plants
B. Replacing long day requirement
C. Overcoming genetic dwarfism
D. All the above

Answer 1

Hint: Gibberellins are plant hormones that help regulate growth and development. They also regulate the flowering, seed production, and sprouting of plants. They take part in ultraviolet radiation, gibberellin biosynthesis, and gibberellin regulation.

Complete step by step answer:
Gibberellin is a hormone found in plants that are involved in growth and development. It has many roles to play, but one of the most important is in helping young plants grow into mature adults by overcoming genetic limitations. The bolting of rosette plants refers to the tendency of these leafy plants to grow taller than they need to be, which can result in some difficulties with harvesting or shipping. Gibberellins help prevent this from happening by keeping the plant where it needs to be at any given time.
Gibberellin is a plant hormone that promotes stem development. Bolting is the fast extension of a rosette plant's stem. Long days or cold treatment are required for bolting. Under normal conditions, rosette plant bolting can be artificially induced by the use of gibberellic acid. As a result, it eliminates the need for a full day of bolting. It also aids in the elongation of internodes, allowing dwarf plants to overcome hereditary dwarfism.
Therefore, Option D is the right answer.

Note: Gibberellins are plant hormones that promote stem elongation and flowering under inductive conditions. Gibberellins are produced by the shoot apical meristem in response to day length, temperature, and moisture deficiencies. This relates to a time in the spring when new leaves have grown but it is still too cold for flowers to be set by sunlight. Some plants have a mutated gene that does not allow them to produce gibberellins naturally, so they need an external source of this hormone to flower and produce fruit and seeds.
