Study Notes
Plant Growth Regulators
- Hormones, vitamins, and other chemicals are broadly classified as plant growth regulators.
Promoters of Plant Growth
- Auxins are responsible for promoting activities like cell division and flowering.
Discovery of Phototropism
- Charles Darwin and his son Francis Darwin discovered the influence causing the bending of coleoptile towards a light source, known as phototropism.
Discovery of Gibberelins
- The foolish seedling disease in rice seedlings, which is a fungal disease, led to the discovery of Gibberelins.
Functions of Abscisic Acid
- Abscisic acid plays an important role in responses to wounds and stress, and regulates dormancy and abscission.
