Inherent trait differences explain wheat cultivar responses to climate factor interactions: New insights for more robust crop modelling

“…Responses to interacting factors will be crucial to correct and adjust crop growth modelling approaches. With few exceptions, studies of multifactorial interaction effects on more than one cultivar are lacking and urgently needed (Hansen et al., 2019). We found multiple three‐way interactions, which proves that a consideration of a single factor is an oversimplification of climatic responses and that source–sink controls are balanced to a very complex degree.…”

“…Numerous publications have explored the effects of elevated CO 2 , enhanced temperature or reduced watering (or drought) on crop physiology in a wide range of crops. Some of these studies have investigated the effects of two climatic factors in combination, but so far, very few studies have looked at the combined effects of all three of those or other climatic factors (Dieleman et al., 2012; Hansen, Hauggaard‐Nielsen, Launay, Rose, & Mikkelsen, 2019).…”

Genetic dissection of bread wheat diversity and identification of adaptive loci in response to elevated tropospheric ozone

“…Others reported chamber fumigation experiments, in which the wild ancestor of bread wheat, Aegilops tauschii , was described as ozone‐sensitive and synthetic hexaploid wheat was rather tolerant (Brewster, Hayes, & Fenner, 2019). In addition, different studies tested the ozone responses of a limited number (usually two) of wheat genotypes that were described as tolerant or sensitive (e.g., Feng et al, 2010; Feng, Pang, Kobayashi, Zhu, & Ort, 2011; Hansen, Hauggaard‐Nielsen, Launay, Rose, & Mikkelse, 2019), but it remains unclear how representative these varieties really were. By summarizing previously published open‐top chamber experiments, Pleijel, Broberg, and Uddling (2019) observed that North American wheat varieties were less sensitive to ozone than European or Asian ones, although this could be a result of experimental differences such as ozone exposure times.…”

Effects of Elevated Temperature and Ozone in Brassica juncea L.: Growth, Physiology, and ROS Accumulation

“…Although many researchers have recently reported the effects of elevated O 3 or temperatures on plants, the interactive effects of these are less studied. In the case of O 3 and elevated temperature, stomata can be important since O 3 enters the plant through the stomata and it has been suggested that elevated temperature may occur intensify O 3 stress due to relation between stomata and temperature [23]. Additionally, leaf mustard is cultivated not only in greenhouses as a crop, but also grown in open fields as one of forest plants where they can be exposed to increased temperatures and ozone levels at the same time.…”
