The response of wheat crops to elevated CO2 (eCO2 ) was measured and modelled with the Australian Grains Free-Air CO2 Enrichment experiment, located at Horsham, Australia. Treatments included CO2 by water, N and temperature. The location represents a semi-arid environment with a seasonal VPD of around 0.5 kPa. Over 3 years, the observed mean biomass at anthesis and grain yield ranged from 4200 ...
The plant hormone auxin is a vital component for plant reproduction as it regulates the development of both male and female reproductive organs, including ovules and gynoecia. Furthermore, auxin plays important roles in the development and growth of seeds and fruits. Auxin responses can be detected in ovules shortly after fertilization, and it has been suggested that this accumulation is a prer...
The frequency of heat events is likely to increase due global climate change, posing an increasing risk wheat production. To optimize crop management strategies for coping with future climates, it crucial quantify the high-temperature occurrence during cropping seasons. Here, sixty-six years (1955~2020) meteorological data reproductive growth were collected from six stations in Huaibei Plain An...
In 2022, a field experiment was conducted to investigate the efficacy of fungicide programs on Fusarium head blight (FHB) and deoxynivalenol (DON) levels. Fungicide treatments were evaluated in plots hard red winter wheat cultivar ‘KanMark’ inoculated with graminearum Parsons, KS. Treatments consisted single application Prosaro, Caramba, Miravis Ace, Prosaro Pro, or Sphaerex at early anthesis (...
Optimum rice population densities and the response of rice yield and yield components to population densities and planting pattern are important factors helping rice producers and researchers to achieve maximum productivity. For this reason, a randomized complete block design experiment was conducted during the summer of 1995 at Isfahan University of Technology Research Farm located at Lavark, ...
Identification of genes for yield components, plant height (PH), and yield-related physiological traits and tightly linked molecular markers is of great importance in marker-assisted selection (MAS) in wheat breeding. In the present study, 246 F8 RILs derived from the cross of Zhou 8425B/Chinese Spring were genotyped using the high-density Illumina iSelect 90K single nucleotide polymorphism (SN...
Deoxynivalenol (DON) concentrations in mature wheat grain are usually correlated with symptoms produced by Gibberella zeae infection. However, there have been numerous observations of unacceptably high DON in asymptomatic crops, which can lead to lower-than-expected milling reductions in DON. We conducted a field experiment with winter wheat to examine the effect of infection timing and postant...
We aimed to optimize field border length in the Huang-Huai-Hai Plain of China (HPC) reduce soil inorganic nitrogen residues and increase absorption utilization by wheat plants using a traditional irrigation system. In two-year experiment (2017–2019) conducted HPC, four lengths were tested: 20 m (L20), 30 (L30), 40 (L40), 50 (L50). Supplementary was implemented during jointing anthesis stages, c...
