BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Gibberellins are also involved in bolting, the rapid elongation of a floral stalk that occurs naturally in many plants, like cabbage, when they initiate flowering. These plants are biennials and show vegetative growth in first year and reproductive growth (flowering) in second year.

Detailed explanation-2: -The best-known gibberellin is gibberellic acid. Compounds such as vitamin E and helminthosporol also have gibberellin-like activity. Gibberellins have striking growth-promoting effects. They speed the elongation of dwarf varieties to normal sizes and promote flowering, stem and root elongation, and growth of fruit.

Detailed explanation-3: -It is concluded that gibberellic acid applied to dwarfs accelerates not exclusively the longitudinal growth of plants but also promotes their transition to the next developmental phases.

Detailed explanation-4: -Auxin and cytokinin are critical growth hormones in plant development and are naturally present within the plant at variable concentrations throughout the season.
