Question

Gibberellic acid induces flowering in
a) Some plants only
b) Long day plants under short day conditions
c) Short day plants under long day conditions
d) Day neutral plants

Answer 1

Gibberellins are plant chemicals that regulate a variety of formative processes such as stem stretching, germination, torpidity, flowering, flower-improvement, and leaf and natural product senescence. GAs is one of the most well-known plant chemicals.

Complete answer:
Gibberellins (GAs) work not only to promote the development of plant organs, but also to accelerate stage progression during development. Their contribution to bloom initiation in difficult days (LD) and biennial plants is grounded, and there is growing knowledge into the components by which botanical enlistment is accomplished.
Biosynthesized geranyl diphenyls are diterpene plant chemicals, a typical $C_{20}$ precursor for diterpenoid, which control and improve various parts of development, including seed germination, stem extension, blooming, biogenic product progression and quality guidelines on the aleurone layer. These gibberellic acids come from higher plants and organisms, but also from microorganisms.
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 treatment 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.

Note:
Gibberellin is a chemical present in seeds, young leaves, and roots of plants. Gibberella fujikuroi is a chemical-producing parasite in the phylum Ascomycota that causes rice plants to grow excessively and yield ineffectively.
