How are red leaves made?

In fact, the red leaves are closely related to the temperature. The main factors that affect the leaf reddening are meteorological factors and the content of plant growth hormone, among which meteorological factors including pre-illumination, temperature and summer precipitation play the most direct role in the change of leaf color, and the most critical factors are the average temperature, minimum temperature and daily variation range of temperature 10 day before the maple leaves turn red.

The kinds of pigments contained in plants are very complicated, including not only chlorophyll, lutein, carotene, but also some anthocyanins. When the temperature drops in autumn and the temperature difference between day and night increases, trees will decompose chlorophyll in leaves and redistribute the decomposed nutrients to trunk and roots for storage. The less chlorophyll, the higher the relative content of other pigments. In addition, the daily temperature difference is beneficial to the formation and accumulation of anthocyanins. At this time, anthocyanin will turn red when it meets acidic cell sap, so the leaves will turn red.

The temperature difference between day and night on the mountain is large, the photosynthesis of leaves is strong during the day, and there are many anthocyanins; The low temperature in the mountains at night makes chlorophyll disappear faster. Therefore, the red leaves on the mountain are red earlier and the colors are gorgeous. How to catch a red leaf?
