This is because the ultraviolet radiation in the mountains is very strong, which destroys the chromosomes of plant cells and hinders the synthesis of nucleotides. Destroy the metabolic reaction of plant cells to varying degrees. In order to survive in harsh environmental conditions, alpine plants have developed a set of survival skills. In order to resist strong ultraviolet rays, it can produce a lot of carotenoids and anthocyanins, and can absorb a lot of ultraviolet rays to make plant cells live normally.
Because alpine plants can produce a lot of carotenoids and anthocyanins, while carotenoids can turn flowers into orange and yellow, anthocyanins can turn flowers into red, blue, purple and so on. Flowers have so much pigment that they produce beautiful flowers.
In addition, the temperature difference between day and night is large in alpine regions. When the temperature is high during the day, flowers fully carry out photosynthesis and synthesize more carbohydrates; At night, the temperature becomes lower, and the carbohydrates synthesized during the day are used to synthesize various pigments in addition to being consumed by breathing. With more pigment, the color will naturally be particularly bright.
