Question

Gibberellic acid induces flowering:

• A. in some gymnospermic plants only
• B. in long day plants under short day conditions
• C. in short day plants under long day conditions
• D. in day-neutral plants under dark conditions

Answer 1

The Correct Option is B

When long day plants are grown under short day conditions, the gibberellins are produced in insufficient quantities and flowering does not occur. However, if the plant is transferred to long day conditions, or gibberellin solution is applied to leaves, flowering occurs.

Answer 2

Gibberellins (GAs) not only enhance plant organ growth but also speed up stage advancement throughout development. Their role to bloom initiation in difficult days (LD) and biennial plants is established, and there is an emerging understanding of the components involved in botanical enlisting.
Geranyl biphenyls are biosynthesized diterpene plant compounds, a common C20 precursor for diterpenoid, that govern and improve different aspects of development, such as seed germination, stem extension, flowering, biogenic product progression, and quality guidelines on the aleurone layer. These gibberellic acids are produced by higher plants and creatures, as well as microbes.
Gibberellic acid is a plant chemical that aids in stem development. Darting refers to rapid blooming with cell division and cell lengthening. Long days or cold treatments are required for shooting. Under normal conditions, the use of gibberellic corrosives can cause blooming. Under short-day conditions, it induces flowering in short-day plants.
Hence, the correct answer is option B-Long day plants under short-day conditions.

 

Answer 3

When long-day plants are cultivated in short-day circumstances, gibberellins are generated insufficiently, and blooming does not occur. Flowering happens when the plant is moved to extended day circumstances or a gibberellin solution is administered to the leaves.
