What will happen to the seed when placed in the dark?

Seeds will not germinate so well in light as in darkness ; because light decomposes the carbonic acid gas, expels the oxygen, and fixes the carbon; thus hardening all the parts of the seed, and preventing vegetation.

Can seeds germinate in a dark room?

Yes, Most Seeds Thrive in Darkness While your seeds may look viable from the outside, they will sprout only when conditions are right or when they are exposed to the proper temperature and the right amount of air, moisture and light, says Harvest to Table.

Should seeds be kept in the dark?

All seeds should be stored in a cool, dry and dark place, preferably in an airtight container. It’s also best if the place of storage has a fairly stable temperature and does not fluctuate too much during certain times of the day.

Can a seed grow without sunlight?

Some seeds don’t need light to break through their seed casings and sprout. Most seeds germinate best with controlled amounts of UV generation, but there are seeds that germinate in the absence of light. Furthermore, there are plants that get enough just light in highly shady areas of a garden or even in darkness.

What seeds require darkness to germinate?

Some other popular types which prefer darkness for germination are:

• Calendula.
• Centaurea.
• Delphinium.
• Gazania.
• Nemesia.
• Primula sinensis.
• Schizanthus.

Why do seeds germinate in dark?

The light slows stem elongation through hormones that are sent down the stem from the tip of the stem. In the darkness, the hormones do not slow stem elongation. The seeds in the dark-grown condition rely upon the stored chemical energy within their cells (lipids, proteins, carbohydrates) to power their growth.

Do seeds need darkness to grow?

Both garden peas and marijuana seeds require darkness. Fewer seeds require darkness than those that require light. These seeds should be planted more deeply when they are planted or, if they are planted in a seed tray, the tray should be covered with something that will keep out the light until the seeds have sprouted.

What happens to the plants after the darkness?

After the darkness, the plants and mittened leaves were returned to light, and their progress was followed further. While the now un-mittened leaves continued to senesce, the fully-darkened plants remained green, and in fact ultimately senesced slower than plants that were kept in the light the whole time.

What happens when seeds germinate in the wrong place?

Sprouting at the wrong time or in the wrong place means certain death for the seedling. The seeds of some plants germinate only when triggered by specific light levels. Ambient light intensity changes with a seed’s depth beneath the soil and the degree of shade.

Why don’t the seeds in the cupboard sprout?

The seeds in the cupboard, away from the light, will not grow. Only the plants that received light will sprout. Why? Plants need light — they can’t survive without it. Light is a very important part of photosynthesis, the process plants use to convert carbon dioxide and water into food.
