Plants do not have calendars, but they can respond to environmental changes some being temperature, day length, and light quality. As the seasons shift, temperature and sunlight drive the chemical production inside the plant leaves. These different chemicals trigger different growth responses.

What prompts flowering in most plants?
Researchers have known since the 1930s that the leaves of plants perceive the seasons by sensing the amount of daylight and, when the time is right, trigger flowering by sending some sort of signal to the shoot tip.
What signals a plant to flower?
In order for flowering to occur, there must be communication between the leaf, where light is absorbed, and the shoot apex, where flowering occurs. Plants have evolved a signaling pathway that involves activation of FLOWERING LOCUS T (FT), a protein whose expression is regulated by the gene, CONSTANS (CO).
How do plants signal?
Plant cells communicate to coordinate their activities in response to the changing conditions of light, dark, and temperature that guide the plant's cycle of growth, flowering, and fruiting. Plant cells also communicate to coordinate what goes on in their roots, stems, and leaves.
Plants: Flowers In Different Seasons
What triggers flowering in plants?
When the light goes down to 12 hours or less, the leaves start to manufacture a substance that triggers flowering, which gets transported to all over the plant. This substance is called florigenflorigenFlorigen (or flowering hormone) is the hypothesized hormone-like molecule responsible for controlling and/or triggering flowering in plants. Florigen is produced in the leaves, and acts in the shoot apical meristem of buds and growing tips. It is known to be graft-transmissible, and even functions between species.https://en.wikipedia.org › wiki › FlorigenFlorigen - Wikipedia or flowering hormone.
What stimulates flowering?
While all elements play a role in plant development and, subsequently, flower development, phosphorus is the element most responsible for stimulating stronger bud, fruit and flower development.
Do plants send electrical signals?
Scientists have known for decades that plants emit electrical signals to sense and respond to their environment.
Seasonal Effects On Plants And Animals
What triggers flowers to bloom?
Researchers have known since the 1930s that the leaves of plants perceive the seasons by sensing the amount of daylight and, when the time is right, trigger flowering by sending some sort of signal to the shoot tip.
How does a plant know when to flower?
The circadian clock regulates the timing of the specific photoreceptor for flowering. That is how plants sense differences in day length.” This system keeps plants from flowering when it's a poor time to reproduce, such as the dead of winter when days are short and nights are long.
How Do Flowers Bloom In The Spring?
Why do some plants bloom in winter?
Repressor proteins within plants keep the genes required to create a flower essentially switched off — until the winter, when the prolonged cold inhibits the expression of the proteins.
How do plants send signals?
So how do they do it? Plants communicatePlants communicatePlant communication encompasses communication using volatile organic compounds, electrical signaling, and common mycorrhizal networks between plants and a host of other organisms such as soil microbes, other plants (of the same or other species), animals, insects, and fungi.https://en.wikipedia.org › wiki › Plant_communicationPlant communication - Wikipedia through their roots by secreting tiny amounts of special chemicals into the soil all through the plant's root zone - what scientists call the rhizosphere. These chemicals, called root exudates, send signals to every other living thing in the root zone.
