Data from: Repeated Mild Summer Drought in Crataegus monogyna Jacq. Provokes Compensation Growth in the Following Year

Data are from the common shrub Crataegus monogyna that experienced two summer droughts, each followed by rewatering. The experimental design consisted of a common garden with potted saplings from a local Belgian, a Swedish and a Spanish-Pyrenean provenance. We quantified the effects on growth and leaf phenology, focusing on the legacies in the year following the droughts. Responses were influenced by the severity of the drought and by its timing.本数据集的实验材料为普通灌木单籽山楂（Crataegus monogyna），该植株先后经历两次夏季干旱胁迫，每次干旱胁迫后均开展复水处理。实验采用同质园试验（common garden）设计，所用盆栽实生苗的种源分别来自比利时本土种群、瑞典种群以及西班牙-比利牛斯山种群。本研究量化了干旱胁迫对植株生长与叶片物候的影响，并重点关注了干旱事件在次年产生的遗留效应。植株的响应特征受干旱胁迫强度及其发生时机的共同调控。
