Difference between the Physiological Effects of Gibberellic Acid and Abscisic Acid – Comparison Table

Compare effects of GA and ABA

Gibberellic Acid (GA) vs Abscisic Acid (ABA)
(Difference between the Physiological Effects of Gibberellic acid and Abscisic Acid in Plants)

Gibberellin (Gibberellic Acid) and Abscisic Acid (ABA) are two important plant hormones. Plant Hormones also called ‘Phytohormones’ or ‘Plant Growth Substances’, are signaling molecules produced in very minute quantities in the plants that have immense physiological and metabolic effects. They regulate the growth and development of plants.

The present post discusses the Difference between the Physiological effects of Gibberellin (Gibberellic Acid) and Abscisic Acid (ABA) in plants with a Comparison Table.

Gibberellic Acid: Gibberellic acid or gibberellin, abbreviated as GA, is a major phytohormone produced by some plants and microbes (fungi) which promote the growth and cell elongation. Gibberellic acid was first identified in Japan as a metabolic by-product of a plant pathogenic fungus called Gibberella fujikuroi. The infection of rice plants with this fungi cause a disease called ‘bakane’ meaning ‘foolish seedlings’. The diseased plants will grow much taller than the normal and they eventually die because they are not sturdy enough to support their own weight. The excessive elongation of the internodes in these infected plants was found be to be due to the effect of Gibberellic acid produced by the pathogen.

Difference between Flower and Vegetative Shoot (Comparison Table )

Flower vs Vegetative Shoot

Flower vs Vegetative Branch
(Difference between Flower and Reproductive Shoot)

The flower is the reproductive structure formed in the plant group Angiosperms or Magnoliophyta, commonly called as the ‘Flowering Plants’. The flower is a ‘modified branch’ or axis developed from a ‘determinate’ apical meristem. The term ‘determinate’ indicates the absence of further growth of the apical meristem after the production of flowers. Even though the flower is a modified shoot, the morphological and anatomical features of a flower and a vegetative branch show many differences. The present post discusses the Difference between a Flower and a Vegetative Branch with a Comparison Table.
