How does germination affect metabolic rate?
Seed germination is crucial stage in plant development and can be considered as a determinant for plant productivity. Seed imbibition triggered the activation of various metabolic processes such as synthesis of hydrolytic enzymes which resulted in hydrolysis of reserve food into simple available form for embryo uptake.
What is germination in microbiology laboratory?
Bacterial germination is the change of an endospore from its resting stage to an actively growing vegetative cell. This takes place when the external environment is favourable for growth by the provision of essential nutrients and water. Germination is divided into three stages: activation, germination and outgrowth.
What is germination function?
Germination is the process in which a plant or fungus emerges from a seed or spore and begins growth. Germination is the growth of an embryonic plant contained within a seed; it results in the formation of the seedling.
What is the mechanism of seed germination?
Seed germination is a complex physiological process that starts with the uptake of water by the quiescent dry seed and terminates with radicle protrusion through the seed covering layers; seed dormancy is an adaptive trait that blocks the germination of seeds under favorable environmental conditions.
What is germination give example?
Germination in plants is the process by which a dormant seed begins to sprout and grow into a seedling under the right growing conditions. In bacteria or fungi, germination is the process in which a spore begins to grow vegetative cells, and sporeling hyphae. Related forms: germinate (verb).
What is Endospore germination?
In chemical terms, endospore germination is a process that uses substrates (germinants and endospores) to accumulate a product (the vegetative cell) over time. Since germinants are not consumed, endospore germination can be analysed using mathematical models developed for enzyme kinetics [81], [82], [83].
What causes a seed to germinate?
All seeds need water, oxygen, and proper temperature in order to germinate. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo’s cells start to enlarge.
