Or they should, anyway. While leaves will always change color as the amount of sunlight wanes, several weather conditions can affect how brilliant they become. High heat or drought can rob leaves of their brilliance, or make leaves drop early. Insufficient rain in September can also hurt peak color.
We hypothesized that if green leaves have a significantly higher rate of photosynthesis (consumption of CO 2) than yellow leaves, because green leaves contain more green chlorophyll a and chlorophyll b photosynthetic pigments than yellow leaves, then the color of the leaves affects the rate of photosynthesis.
