The phenomenon of flowers opening before the usual time.. How and when does the plant know when to bloom?
Arab Weather - All plants are equipped with devices that can pick up signals from the environment that are translated into internal chemical processes called "stimulants" that ensure that the plant does not flower or germinate in the wrong season to ensure the right time for its continued survival. Through activation freezing (Vernalization), it is the need for a sudden cooling period for seeds and vegetative groups in order for flowering to occur, which means shortening the vegetative growth period and pushing plants to flower early. In addition to the hours of light and darkness during the day and seasons, which is the photoperiod (Photoperiodism) is an expression that means the length of daylight hours, which is a factor that can affect plants. The length of the photoperiod affects vital physiological processes in the plant such as flowers, yellowing and falling leaves, in addition to storing food in the plant.
The effect of light on plant flowering is explained by the fact that under the appropriate lighting conditions to which plants are exposed, the flowering hormone (Florigen) is formed in the plant, which is responsible for the plant’s transition from the vegetative growth stage to flowering.
But if we examine this period of winter, especially during the 2024/25 square year,
It was a period of more than three weeks during which the rains were withheld and the temperatures increased. The sky was also clear, which increased the hours of light. As a result, some plants were affected and suffered from “confusion or disturbance” in the enzyme balance system between the vegetative reproduction enzymes and the flowering enzymes. This caused some of these plants to flower at the wrong time.
And this year.
The phenomenon of some plants or flowers blooming before their natural time, such as almond trees and wild lupine flowers, was observed.
