Abstract

Changes in day (maximum temperature, T-MAX) and night temperature (minimum temperature, T-MIN) in the preseason (e.g., winter and spring) may have opposite effects on early phenophases (e.g., leafing and flowering) due to changing requirements of chilling accumulations (CAC) and heating accumulations (HAC), which could cause advance, delay or no change in early phenophases. However, their relative effects on phenology are largely unexplored, especially on the Tibetan Plateau. Here, observations were performed using a warming and cooling experiment in situ through reciprocal transplantation (2008-2010) on the Tibetan Plateau. We found that winter minimum temperature (T-MIN) warming significantly delayed mean early phenophases by 8.60 d/degrees C, but winter maximum temperature (T-MAX) warming advanced them by 12.06 d/degrees C across six common species. Thus, winter mean temperature warming resulted in a net advance of 3.46 d/degrees C in early phenophases. In contrast, winter T-MIN cooling, on average, significantly advanced early phenophases by 5.12 d/degrees C, but winter T-MAX cooling delayed them by 7.40 d/degrees C across six common species, resulting in a net delay of 2.28 d/degrees C for winter mean temperature cooling. The opposing effects of T-MAX and T-MIN warming on the early phenophases may be mainly caused by decreased CAC due to T-MIN warming (5.29 times greater than T-MAX) and increased HAC due to T-MAX warming (3.25 times greater than T-MIN), and similar processes apply to T-MAX and T-MIN cooling. Therefore, our study provides another insight into why some plant phenophases remain unchanged or delayed under climate change.
