Here are the conditions that must be met for a seed to develop into a seedling, and then into a mature plant:
Moisture
Without mentioning water, seed germination cannot be discussed. Keep in mind that water absorption is the first stage of any seed’s development.
Some seeds need to absorb a lot of water in order to start germination because they are rather dry. Water assists seed germination by assisting with the following:
- It facilitates nutrition transport.
- It gives the embryo dissolved oxygen.
- It facilitates the cotyledons’ release from the seed coat.
- It supports metabolic processes inside the seedling.
Luz
Depending on the type of plant, light may be just as essential to its survival as darkness is to others.
Some plants won’t sprout until light shines on them because light acts as an external trigger for the germination process in seeds.
Temperatura
A seed needs a temperature of between 25 e 30 °C to germinate. While some seeds need considerably less heat than this to germinate, some need much more. The ideal temperature range, no entanto, is between 5 e 40 ° c.
Since some plants are grown from seeds that are put outside and allowed to germinate on their own, temperature also affects the time it takes for some seeds to sprout.
Air/Oxygen
Oxygen is necessary for metabolism, energy production, and seed germination. They must first engage in aerobic respiration before they finally manufacture their own nutrients.
The importance of oxygen also affects how some seeds are placed; some seeds don’t grow well when buried too deeply in the soil.
