Effects of Spring Warming and Drought Events on the Autumn Growth of Larix kaempferi Seedlings

High temperatures and droughts following winter dormancy can negatively affect seedling growth mortality. An open-field experiment was conducted to study the mortality of Larix kaempferi seedlings in response spring warming drought treatments determine whether could regain their capability once were discontinued. In May 2020, 1-year-old exposed four treatments: control, warming-only, drought-only, combined drought. Drought treatment reduced height root collar diameter increased rate. The had highest rates, followed by drought, treatments. However, after cessation treatments, height, diameter, individual biomass because high rate relaxed competition among seedlings. This suggests that effects low on surviving may mitigate negative growth. Our demonstrates despite decreased during period, subjected temperature stress showed short-term levels compared a single stress.
