资源简介：
38 temperate maize varieties (hybrids, open-pollinated varieties and landraces) were grown in pots in an automated phenotyping facility. After an initial growth period (37 days after sowing), half of the plants of each variety were subjected to drought stress by withholding irrigation, while the other half remained under well-watered conditions (av. -60 hPa). The experiment was sampled (64 DAS) when the last drought-stressed plant had reduced its transpiration rate by at least 50%. We determined soil water contents at sampling, rhizosheath mass and aggregation, chemical and isotopic composition of rhizosheath soil, extracellular enzyme activities within the rhizosheath and root colonization by arbuscular mycorrhiza.
