The following points highlight the eight physiological effects of gibberellins. The effects are: 1. Seed Germination 2. Dormancy of Buds 3. Root Growth 4. Elongation of the Internodes 5. Bolting and Flowering 6. Parthenocarpy 7. Light Inhibited Stem Growth and 8. De novo Synthesis of the Enzyme-α-Amylase. Physiological Effect # 1. Seed Germination: Certain light sensitive seeds e.g., lettuce and [...]
Let us make an in-depth study of the mechanism of auxin action in plants. Auxin (IAA) causes wide range of physiological effects in plants. Some of these effects such as cell elongation in shoot occur in minutes in response to auxin while others such as abscission occur in days in response to auxin treatment. Among these, the most important physiological [...]
