“…For one thing, temperature elevation can increase the activity of photosynthetic, enzymes, and carbonic anhydrase, which likely caused the increases in ramet number in our experiment (Olesen and Madsen 2000). For another thing, excessive elevated temperature caused a highly significant decrease in the abscisic content and an increase in the gibberellic acid hormones, which led to a decrease in tillering capacity (Morales‐Coronado et al 2019). Moreover, higher temperatures significantly reduced the clonal reproductive traits under salt stress.…”

In a scenario of climate change and intensive land-use change, the issue of salt marsh degradation caused by global warming and soil salinization is becoming more serious. A climate chamber experiment was conducted to examine the responses of tuber sprouting and seedling growth of Schoenoplectus nipponicus to variations in the temperature regimes (20/10, 25/15, 30/20 and 35/25°C; 12-h light/dark 12-h photoperiod) and different salt concentrations (0, 50, 75, and 100 mmol/L salinity). Results showed that the final sprouting percentage decreased with the increase in salinity and increased with the rising temperature. Salinity lower than 50 mmol/L was the most favorable for tuber sprouting. Under high salinity (75 and 100 mmol/L salinity), the inhibition of tuber sprouting at 20/10°C was greater than other temperature regimes. Along the temperature gradients, both plant height and leaf N content increased, and root length decreased under non-saline-alkali conditions, while plant height, leaf N content, and root length declined significantly under salt stress (50, 75, and 100 mmol/L salinity). With the increase in temperature, the production of tubers under the control treatments was enhanced significantly, but that under salt stress declined significantly. Under 0 mmol/L salinity, the accumulation of biomass in various organs increased with rising temperature. Biomass accumulation increased first and then declined for plants grown under salt stress, with a peak value of 25/15°C. Root: shoot ratio was reduced significantly under the combination of high salt stress (75 and 100 mmol/L salinity) and high temperatures (30/20°C and 35/25°C). Our study will contribute to a better understanding of the influence of climate warming and increasing serious human disturbances on this important wetland species.

“…In the studied area, tillering occurred from January until March. This phenological stage is critical in determining the final yield, and durum wheat requires an ever‐increasing temperature to continue its phenological progression (Al‐Karaki, 2012; Morales‐Coronado et al., 2019). Therefore, the yield may reduce if increased and decreased temperatures are observed during the crop growing period.…”

According to climate change projections, global temperatures would increase by 2°C by 2070, and agriculture is expected to be among the most affected sectors, particularly intensive field crops like cereals. Therefore, researchers need to investigate the most cost‐effective agricultural strategies that can prevent production losses and ensure global food security. This study aimed to identify the limiting factors of durum wheat (Triticum turgidum L. subsp. Durum (Desf.) Husn.) yield production under Mediterranean conditions. Durum wheat yield data of over 5 years (2017–2022), from a 30‐year rainfed long‐term experiment conducted in the ‘Pasquale Rosati’ experimental farm of the Polytechnic University of Marche in Agugliano, Italy (43°32’ N, 13°22′ E, 100 a.s.l.) on Calcaric Gleyic Cambisols with a silt‐clay texture, were analysed and compared with the recorded thermo‐pluviometric trend. The field trial included two soil managements (no tillage vs. conventional tillage) and three Nitrogen (N) fertilization levels (0, 90, and 180 kg N ha−1). The most important driver for durum wheat production was N fertilization. However, in the absence of N fertilization, no tillage showed a higher yield (+1.2 t ha−1) than conventional tillage due to the accumulation of organic matter in the soil. When wheat was fertilized with 90 kg N ha−1, no tillage resulted in 25% yield more than conventional tillage (+1.2 t ha−1), but this occurred only when the increase in temperatures was constant from January until harvest (this happened in 3 of 5 years of monitoring). The non‐constant increase in temperature from January to wheat harvest may hamper crop phenological development and reduce the potential yield. The highest fertilization rate (180 Kg N ha−1) resulted in the highest wheat yields regardless of soil management and thermo‐pluviometric trends (5.78 t ha−1). After N fertilization and soil management, the minimum and maximum temperature in February and the maximum temperature in April were crucial for durum wheat production under Mediterranean condition. When there is non‐constant increase in temperature from January to wheat harvest no‐tillage should be preferred over conventional tillage because wheat yields did not reduce under no tillage. Thus, agricultural policies that support the switch from conventional tillage to no‐tillage management should be promoted to enable food security in Mediterranean environments.

“…The same phenomenon occurs with the appearance and development of stripe rust, leaf rust, and spot blotch of wheat in the two valleys [11,12]. Several studies that have been carried out using the data provided by weather stations [9,13,14], have demonstrated that the fluctuation of the temperature and the humidity between sites of the Yaqui and Mayo Valleys induce differences in yield of crops, and have influence upon the presence and incidence of pests and diseases in the different areas of the valleys. Plants present distinctive elements by the effect of climate, whether they are adverse or beneficial to their growth and development, as well as for their exposure or protection from those climatic factors.…”

The influence of climate upon a plant disease is a consequence of the causal agent and its interaction with the host plant. Plants present distinctive elements by the effect of climate, whether they are adverse or beneficial to their growth and development, as well as for their exposure or protection from those climatic factors. The objective of this work was to analyze the influence of temperature and relative humidity in relation to commercial wheat fields which presented leaf rust in different areas of the southern region of the state of Sonora, Mexico, during the crop seasons 2017-2018, 2018-2019, and 2019-2020. Weather data were recorded from 23 weather stations that belong to the automated weather station network of the state of Sonora which comprise the Yaqui and Mayo Valleys. A Voronoi diagram was constructed to delimit the region which corresponded to each weather station, and so to locate each of the commercial wheat fields with leaf rust incidence, in order to analyze the weeks in which disease incidence was high. A “t student test” of independent samples was performed in order to compare the weather variables (average, maximum and minimum temperature, as well as relative humidity) during the three crop seasons, from the weather stations where commercial wheat fields were detected with the presence of leaf rust, with respect to those where the disease was not present. Relative humidity was the main key factor for the presence of leaf rust, since it is the variable where the mean of groups with and without the presence of leaf rust, showed statistical significant difference in each crop season, unlike the average and the minimum temperature which showed difference only during the 2017-2018 crop season, and the maximum temperature during 2019-2020.
