Study Notes
- Meristematic cells are rich in protoplasm, have cell walls that are primary in nature and have large conspicuous nuclei
- Auxin was isolated from tip of coleoptiles of oat seedlings by F.W. Went
- Bakane disease of rice seedlings is caused by the fungus Gibberella fujikuroi
- Gibberellin is sprayed on young conifers to hasten maturity and early seed production
- Ethylene is used to initiate flowering and for synchronising fruit set in pineapple
- Growth measurement parameters include fresh weight, dry weight and surface area, but not cell type
- Spraying sugarcane crop with gibberellins increases the length of the stem, increasing the yield by as much as 20 tonnes per acre
- Gibberellin is not present naturally in plants
- Breaking bud and seed dormancy is not a function of ethylene
- Plants follow different pathways responding to the environment to form different kinds of structures, a process called plasticity
- Gibberellins cause fruits like apples to elongate and improve their shape
- 2, 4-D is a synthetic auxin
- ABA increases the tolerance of plants to various kinds of stresses
- GA3 is used to speed up the malting process in the brewing industry
