Question

______________is used to speed up the malting process in the brewing industry.

• A. NAA
• B. GA3
• C. Kinetin
• D. Abscisic acid

Answer 1

The correct option is B GA3

Malting is the process in which barley or wheat or sorghum are soaked in water, allowed to germinate. GA3 is used to speed up the malting or the seed germination process in the brewing industry. GA3 was one of the first gibberellins discovered.

NAA stands for 1-naphthalene acetic acid is a synthetic auxin. Auxins are plant growth promoters. They initiate root formation in stem cuttings, promotes flowering and promotes natural detachment of old leaves and fruits termed as abscission.

Kinetin belongs to the cytokinin group. Cytokinin is a plant growth promoter. They are found in the regions of rapid cell division e.g in root apices. It helps in cytokinesis, i.e the division of the cytoplasm of a parent cell into 2 daughter cells.

Abscisic acid is a plant growth inhibitor. It inhibits the development and maturation of seed along with other growth-related activities. It promotes closure of stomata.
