Q. Bakane disease leads to the discovery of which phytohormone (PGR)?

NTA AbhyasNTA Abhyas 2020Plant Growth and Development

Solution:

Phytohormone is plant hormones that are responsible for the growth and development of the plants. Some of them include gibberellic acid (GA), auxins, abscisic acid (ABA), cytokinins(CK), etc. Bakane disease also called the foolish seedling disease of rice, affects the rice plants, and is caused by the fungi Gibberella fujikuroi. The phytohormone, Gibberellins were first isolated from these fungi which caused the foolish seedling disease of rice plants and thus Bakane's disease led to the discovery of the plant hormone gibberellic acid (GA).
