Germany has experienced a temperature increase of about 1.7 °C over 136 years (1881-2017) and the beginning of flowering date has advanced by about 17 days on average. In China, the temperature has increased by about 2 °C over 45 years (1963-2008), and the beginning of flowering date has advanced by about 9 days on average. Due to the large differences in the amount of data and recording time between the two countries, it is not possible to concretely conclude whether plants begin to flower is more sensitive to temperature changes in Germany or in China. However, it can still be concluded that temperature is an important factor in determining flowering time. In general, phenology is a very suitable tool for the study of effects of climate change, and climate change can also lead to a more detailed study of phenology. Overall, after evaluating the slopes of the same species in China and Germany, there was a surprising similarity of the slopes. And that it is surprising as well that all reliable datasets showed a tendency towards a shift of flowering in spring to an earlier DOY.}, language = {en} }
