Question 4: When did the five-pointed maple leaves turn red? Acer truncatum, also known as Acer truncatum, is a small deciduous tree of Aceraceae. Like maple leaves, the color change in autumn is closely related to the temperature and sunshine of that year:
The maple leaf supervision and research center in Vermont, USA, studied the effect of autumn temperature on the discoloration of maple leaves. There are many reasons why maple leaves turn red. However, temperature, sunshine and night temperature are one of the reasons. Maple leaves turn red because the temperature is low at night in autumn, and the high temperature and strong sunshine during the day may change the above factors (high temperature and warmth at night).
In autumn, affected by the shorter sunshine time, the chlorophyll content in plants decreased and the anthocyanin content increased, and the leaves were yellow and orange, and then gradually turned red.
Researcher Abby? Vandenbergh said that this study will focus on anthocyanins contained in plants. Researchers will study whether the cold temperature at night is one of the reasons for the discoloration of maple leaves.
The United States is using it as an intuitive sign to study global climate change, and this observation can also judge that your place is warm autumn this year.

"There is a lot of rain in summer, which is very beneficial to the growth of red leaves."
