The plant pathologist Kenkichi Sawada, working at the Imperial Research Institute at the Department of Agriculture in Taipei, Taiwan, was the first to suggest that the bakanae fungus provided the stimulus that caused the overgrowth symptoms in rice (Sawada ).This was later confirmed by his colleague Eiichi Kurosawa, who.
Gibberellins have almost no effect on the growth of roots. However, some inhibition of growth can occur at a higher concentration in a few plants. Elongation of the Internodes. Internodes elongation is the most pronounced effects of gibberellins on plant growth.
In many plants such as dwarf pea and maize, the genetic dwarfism can be overcome. Gibberellin definition is - any of several growth-regulating plant hormones that promote cell elongation and activity of the cambium, induce parthenocarpy, and stimulate synthesis of nucleic acids and proteins.

In this article we will discuss about: 1. History of Gibberellins 2. Bioassay of Gibberellins 3. Functions 4. Uses. History of Gibberellins: The effect of gibberellins had been known in Japan since early where certain rice plants were found to suffer from bakane or bakanae (foolish seedling) disease.
Sep 24, · Bioactive gibberellins (GAs) are diterpene phytohormones that modulate growth and development throughout the whole life cycle of the plant.
