Why is it an advantage that most seeds go through a stage of dormancy before germination?
Seed dormancy is the failure of a viable seed to germinate under otherwise favorable conditions. Dormancy allows seed dispersal, reducing intraspecies competition and increasing colonization. Dormancy helps seedlings to avoid harsh seasonal or unpredictable environmental conditions.
What is the advantage of seed dormancy?
In temperate zones, the dormancy of seeds helps the plants to tide over severe cold which may be injurious for their vegetative and reproductive growth. In tropical regions, the dormancy of seeds resulting from their impermeable seed coats ensures good chances of survival during water stress.
What is dormancy explain what’s happening in germinating seeds that’s causing them to have a higher rate of respiration than dormant seeds?
The seed will use those calories to survive during dormancy and to germinate. To fulfill the high-energy needs of a germinating seedling, cellular respiration increases as a seed emerges from dormancy and begins germinating. However, seeds respire at a lower rate throughout dormancy.
What conditions do most seeds need to germinate?
We know that seeds need optimal amounts of water, oxygen, temperature, and light to germinate.
Will a damaged seed grow?
Broken seeds can be added to the compost bin or planted around growing vegetables and flowers. They won’t sprout, but they will add nutrients to the soil as they decay.
Do seedlings need direct sunlight?
Most seeds will not germinate without sunlight and will perform best with 12 to 16 hours each day. Indoors, place seed containers in a sunny, south-facing window and give the container a quarter turn each day to prevent the seedlings from overreaching toward the light and developing weak, elongated stems.
At what point do you transplant seedlings to bigger pots?
6 to 8 weeks
How big should seedlings be before potting on?
The general rule of thumb is that when a seedling has three to four true leaves, it’s large enough to plant out in the garden (after it has been hardened off). When you plant a seed, the first leaves to emerge are the cotyledons. These leaves will look different from leaves that will grow later.
How big should seedlings be before thinning?
about 3 to 4 inches
What happens if you transplant seedlings too early?
Timing is important when it comes to transplanting: transplant too early in spring and your plants may succumb to frost, transplant too late and your plants may get baked in the sun (and the opposite is true in autumn). In any case, it’s important to pay attention to local weather conditions.
Will my plant recover from transplant shock?
While there is no sure-fire way to cure plant transplant shock, there are things you can do to minimize the transplant shock in plants. Wait patiently – Sometimes a plant just needs a few days to recover from transplant shock. Give it some time and care for it as you normally would and it may come back on its own.
How long does it take for a wilted plant to recover?
If it’s lack of water, it might recover after 2–3 days, unless it has dried out, which make it unrecoverable. If it is overwatering, it might recover after several weeks, as the plant took that much time to regrow damaged/wilted parts. However if it is overwatered and rotten, then it is a goner for sure.
Should you water right after repotting?
Water heavily, drench them, right after you repot. The water on the surface will evaporate relatively quickly, but moisture will still be trapped in the deeper soil… so that’s where the roots will do. You’ll be encouraging deep, healthy roots that anchor the plant AND provide it more access to water and nutrients.
Is it normal for plants to wilt after transplanting?
Damaged Roots During Transplanting It is quite normal for such a plant to show wilting right after being moved. It is quite common for people to water far too much after transplanting in order to try and fix the problem. Too much water does not help the problem.
