Determinants of legacy effects in pine trees – implications from an irrigation‐stop experiment

What is it about?

Tree responses to altered water availability range from immediate (e.g., stomatal regulation) to delayed for years (e.g., crown size adjustment). The underlying mechanisms of the so-called legacy effects are poorly understood so far. We explain why pine trees take four years of time to reduce their radial stem growth rates after being exposed to a water shortage.
