BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Gibberellins stimulate germination of seeds. Gibberellins break the stored food by stimulating the production of enzymes during germination and end seed dormancy.

Detailed explanation-2: -The transition from dormancy to germination in seeds is a key physiological process during the lifecycle of plants. Abscisic acid (ABA) is the sole plant hormone known to maintain seed dormancy; it acts through a gene expression network involving the transcription factor ABSCISIC ACID INSENSITIVE 3 (ABI3).

Detailed explanation-3: -GA is required to break seed dormancy leading to its germination. Seed germination is a complex process, controlled by both physical and internal regulating factors. GA plays very important role in controlling and promoting germination in cereal grains and other crop species.

Detailed explanation-4: -Ethylene breaks the seed and bud dormancy and initiates seed germination.

Detailed explanation-5: -Abscisic acid is one of the major plant hormones involved in many aspects of plant growth and developmental processes including seed dormancy and germination.
