The beauty of nature lies in its four seasons, and flowers are plants that best represent season personality.

Spring is the first season of one year. At this time, the climate was warm and full of vitality. Most beautiful flowers choose to open in spring. What are the scientific principles behind this? Scientists have studied this interesting phenomenon.

Studies have found that during the process of evolution of millions of years, plants have formed a complex mechanism through evolution. They can integrate the analysis of endogenous signals and seasonal information, thereby regulating their gene expression and external forms, regulating the flowering time, so as to achieve the purpose of adapting to the environment.

Part of the reason most beautiful flowers bloom in spring is because the temperature is favorable. The more important reason is that some plants need long periods of sustained cold temperatures in the winter to flower in the spring.

The process by which plants bloom in the spring is called vernalization. For many plants, flowering at the wrong time of year would be a disaster. Some plants germinate in autumn and produce seedlings as soon as winter comes. If they bloom at this time, they will be difficult to pollinate because the weather is too cold. Even if the pollination is successful, the embryo is difficult to develop normally.

Another reason for flowers to bloom in spring is the gradual increase in daylight hours as spring approaches. The increase of sunshine time will make air temperature and ground temperature gradually increase, which is conducive to seed germination.

Many flowers are biologically programmed to bloom soon after germination, giving them plenty of time to accumulate nutrients for seeds and fruit in the following days.

Most plants living in nature can bloom, but some plants are not obvious when blooming. For common flowers, flowering is mainly to spread pollen. Their flowers are very bright, and most of them are accompanied by fragrance, which can attract insects to spread pollen to complete the purpose of fertilization.

Flowers play an important role in life, mainly in the following three aspects:

Flowers have important positions and functions in the construction of ecological environment. There are many types of flowers and widely used.For landscaping, flowers are important materials.

Flowers also have important positions and functions in people's cultural life. Flowers beautify people's lives, increase people's aesthetic taste, and improve people's cultural living standards. In daily activities, flowers have the role of improving relationships and promoting scientific and cultural exchanges.

In addition, the rich variety of flowers and the scientific secrets in them provide conditions for people to understand nature, to increase scientific knowledge, to conduct teaching and scientific research. Flowers also play an important role in economic production.
