What Are The Conditions Necessary For Germination Of Seed?

For germination to take place the seed must be viable or living and should have sufficient food for its germination. The following environmental conditions must exist. First is moisture or water, second is air r oxygen and third is suitable temperature.

Through micropyle, the seed absorbs water, which swells it, causing the seed coat to burst. This helps the root to emerge out of seed. Water absorbed by the germinating seed help to activate the enzymes to digest the food of seed, which is made available to the growing embryo. It also helps to elongate hypocotyl and epicotyl, to grow it.

Air is necessary for seed germination because oxidative metabolism usually takes over soon after a plant embryo starts to grow; most seeds require oxygen for germination. So, air is very important for germination as it contains about 21 percent of oxygen, which is used during respiration.

As far as temperature is concerned, germination of seeds occurs over a wide temperature range between 5 to 30 °C. Suitable temperature is necessary for the enzymes to function properly. During early germination of seeds, the vital metabolization of food reserves stored in the embryo cotyledons or the endosperm is mediated by hormones, which in some cases are gibberellin.

Water, oxygen and a suitable temperature

Water/ Moisture, Air (oxygen), warmth, sunlight is not needed for no chlorophyll is present in the seeds (chlorophyll is only found in leaves). All these conditions will ensure the seed gets the stored food inside. (:

Seeds, in order to germinate, should always be moist or wet. Some seeds need to be with another seed in order to get the germination process active. Put it in a warm place; not in the sun. If you forget to water the seeds, they will dry and eventually die.

It will need the amount of sunlight,food and water.
