Abstract
The frequency and severity of drought events have increased with climate warming. This poses a significant threat to tree growth and survival worldwide. However, the underlying mechanism of tree growth responses to drought across diverse geographic regions and species remains inconclusive. Here, we used 2808 tree ring width chronologies of 32 species from 1951 to 2020 to examine the relationships between growth rates and resistance and recovery of trees in response to drought in the Northern Hemisphere. We found that trees with fast growth rates exhibited lower drought resistance but higher drought recovery compared to those with slow growth rates, which was further corroborated by the trade-off between resistance and recovery in response to variations in leaf photosynthetic traits. The difference in growth rates also well explained the large variability in the drought resistance and recovery for different geographic regions as well as for species from different clades and successional stages. Our study provides a conclusive and uniform perspective that tree growth rate regulates drought resistance and recovery, shedding light on the diverse strategies employed by tree species in response to drought stress in the Northern Hemisphere.
