BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Gibberellins are a group of phytohormones that regulate plant developmental processes such as seed germination, flowering, stem elongation, breaking dormancy, sex expression, and leaf/fruit senescence (Hedden and Phillips, 2000).

Detailed explanation-2: -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-3: -Gibberellins‐mediated control of seed dormancy release and germination. A high level of gibberellins (GA) is needed for the counteraction of ABA activity in seeds. GA promotes seed dormancy release and radical protrusion during seed germination.

Detailed explanation-4: -Gibberellins are tetracyclic diterpenoid hormones that stimulate aspects of plant development, such as root and shoot elongation, seed germination, flower transition, and fruit set and expansion (1).
