TL;DR: In this paper, 15 wheat growth models of a larger MME were improved through re-parameterization and/or incorporating or modifying heat stress effects on phenology, leaf growth and senescence, biomass growth, and grain number and size using detailed field experimental data from the USDA Hot Serial Cereal experiment (calibration data set).

TL;DR: In this article, the authors show that the hyphal lengths of arbuscular mycorrhizal fungi (AMF) increased strongly with a threefold increase in the dry treatment, and the concentrations of one fraction (easily extractable glomalin, EEG) of the AMF-produced protein Glomalin were also increased.

TL;DR: In this article, the authors evaluated the performance of two spring wheat crops, grown in a well-watered, subsurface drip-irrigated field under ambient (about 370 mmol mol 1 during daytime) and enriched (200mmol mol 1 above ambient) CO2 concentrations during 1995-1996 and 1996-1997 in Free-Air CO2 Enrichment (FACE) experiments in central Arizona.

TL;DR: In this paper, the effects of elevated CO 2 concentration and drought on plant water relations of wheat (Triticum aestivum L.) have been investigated in a 2-yr study, where a spring wheat (cv. Yecora Rojo) crop was exposed to ambient (Control: 370 μmol mol -1 ) and free-air CO 2 enrichment under ample (Wet), and reduced (Dry), water supplies.

TL;DR: In this article, the authors evaluate whether simulation of Tc improves the ability of crop models to simulate heat stress impacts on wheat under irrigated conditions and find that using Tc to account for heat stress effects did improve simulations compared to using only Tair to a relatively minor extent, but the models that additionally use Tc on various other processes as well did not have better yield simulations.
