Data from: Associations between developmental stability, canalization and phenotypic plasticity in plants with temporally heterogeneous environmental experience

We subjected eight plant species to a first round of alternating
inundation and drought vs. constantly moderate water treatments and a
second round of water conditions. Fluctuating asymmetry (FA), intra- and
inter-individual variations (CVintra and CVinter), and plasticity in
traits were measured and correlations between variables were calculated
for each species. Early temporally heterogeneous experience
decreased the leaf size of half of the species, but had complex effects on
leaf fluctuating asymmetry (FA) and inter-individual variation (CVinter)
in traits immediately or in late conditions, with little effects on
intra-individual variation (CVintra). There were several positive
correlations between FA and CVinter, while there were correlations between
CVinter and plasticity in early treatments, but negative ones in late
treatments.

本研究以8种植物为试验材料，设置两组处理：第一组施以周期性淹水与干旱交替的水分胁迫，第二组维持持续适度的水分管理；随后对所有供试材料开展第二轮水分条件处理。本研究测定了各物种的波动不对称性（Fluctuating asymmetry, FA）、个体内变异系数（CVintra）、个体间变异系数（CVinter）以及性状可塑性，并计算了各物种内各变量间的相关系数。
早期的异质性水分经历会使半数物种的叶面积减小，但该经历对叶部波动不对称性（FA）与性状个体间变异（CVinter）的影响较为复杂，其效应可在处理初期或后期显现，而对个体内变异系数（CVintra）几乎无作用。
FA与CVinter间存在多组正相关关系；CVinter与早期处理下的性状可塑性存在相关关系，但在处理后期则表现为负相关关系。
