Question: Do our seeds have a light requirement for germination?
Hypothesis: my seeds grow wear out in darkness than in light over 14 days.
Predictions: If my seeds do not require light, then the germination serving for the seeds siced in the light and dark should be the same.
crack: window sile for sun light
Dark cupboard
Room temperature
Apparatus: 2 containers
200 mustard seed
100 mustard seeds
water system (200 ml)
Fertilized blur and ground tend soil
Method: mix the fertilized soil and the garden soil.
Divide the sand by making equal squ ares to plant each seed.
Place 100 mustard seeds in one container and 1 mustard seed in each square.
Water both the seeds once a week.
Results:
light
Dark
Discussion:
Seeds will not germinate so well in light as in darkness; because light decomposes the light speedic acid gas, expels the oxygen, and fixes the carbon; thus hardening all the parts of the seed, and preventing ve loweration.
Seeds sown as soon as they are gathered, generally vegetate, at the latest, in the ensuing spring; but when they are first change out they will frequently lie a whole division in the soil without vegetating. Many seeds, when buried beyond a certain depth, lose their vegetative powers; others, as clover, retain them, and when brought up to the surface, will germinate, after having been buried for many years. The conditions which are necessity for the germination of seeds are heat, moisture, and atmospheric air; and the reverse of these are the most favorable for conveying seeds to a distance. After such(prenominal) experience it has been found, that seeds packed loosely in coarse opinion poll bags, and hung to the ceiling of the cabin of a ship, where they are perfectly dry and cool, will retain their vegetative powers much better...If you want to get a full essay, order it on our website: Ordercustompaper.com
