Previous studies have shown that spring cold spells lead to shrivelled grains and poor grain filling. To explore the physiological mechanisms underlying these effects, two wheat cultivars, ‘Yannong 19’ (low temperature-tolerant) and ‘Wanmai 52’ (low temperature-sensitive), were used. Controlled low-temperature treatments were applied in artificial climate chambers using three temperature levels (2°C, 0°C, and −2°C) and two treatment durations (24 h and 48 h). This study evaluated the impact of low-temperature stress at the booting stage on grain yield, sucrose and starch accumulation, the activity and gene expression of starch-synthesizing enzymes, and the dynamics of dry matter accumulation and translocation. The results showed that low-temperature stress significantly decreased the number of grains per spike, thousand-grain weight, and grain starch content. Notably, these reductions were exacerbated with lower temperatures and longer exposure times. The activities of key starch-synthesizing enzymes, including invertase, starch phosphorylase 1, disproportionating enzyme 1, and ADP-glucose pyrophosphorylase, decreased progressively with decreasing treatment temperature and increasing stress duration. Meanwhile, the relative expression levels of starch synthesis–related genes in grains (<i>AGPase</i>, <i>GBSSI</i>, <i>SSSI</i>, <i>SSSII</i>, and <i>Pho1</i>) were significantly downregulated. After low-temperature stress, non-structural carbohydrate content in the stem sheaths decreased at heading but increased at maturity, indicating that the non-structural carbohydrate translocation amount, translocation rate, and its contribution to grain weight were reduced. Similarly, dry matter allocation and proportion in grains at maturity were significantly decreased. In summary, low-temperature stress during the booting stage suppresses starch synthesis initiation, starch accumulation and the translocation of assimilates to the grains, thereby significantly reducing wheat grain yield.</p>\u0000 </div>","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":"212 3","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147578124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This knowledge forms the basis for simulating and quantifying the impact of dry hot winds during the late growth stage on yield losses of wheat in northern China. Using potted wheat plants, we established four treatments at the flag leaf stage: ambient temperature with well-watered conditions (control, CK), elevated temperature (H), mild drought (D), and combined elevated temperature and drought (HD). After 25 days of treatment, gas exchange parameters, light response curves, and stomatal morphology of the flag leaves were measured. Stomatal conductance models were fitted, and differences in the parameters among treatments were analysed, with an attempt to identify the sources of variability in each parameter. The results showed that (1) the H treatment induced moderate stomatal closure (stomatal opening reduced by 20.1%), maintaining stable net photosynthetic rate (<i>A</i>_n) while improving CO₂ assimilation efficiency (16.4% decrease in intercellular CO₂ concentration), thereby forming an efficient water use strategy; (2) under D and HD treatments, the maximum net photosynthetic rate (<i>P</i>_max) decreased by 19.9%–25.5%. Additionally, the photosystem adapted to low-light conditions by downregulating the light saturation point (<i>I</i>_sat: 41.9%–42.5%) and light compensation point (<i>I</i>_c: 38.0%–51.6%); (3) Morphological parameters such as stomatal density and stomatal area remained stable, while stomatal aperture significantly decreased by 20.1%–37.8% under H, D, and HD treatments, and the theoretical maximum stomatal conductance (<i>g</i>_smax) significantly decreased by 17.6%–18.4%, revealing the rapid response characteristics of stomatal dynamic regulation; (4) The slope parameters (<i>m</i> and <i>g</i>₁) of the Ball-Berry and Medlyn models showed a significant positive correlation with stomatal aperture, with a significant decrease in parameters under the H treatment (41.1% and 32.7%), confirming that stomatal movement is the core regulatory factor for model parameters.

The system integrates rotor-based airflow sensors, real-time data acquisition and feedback-controlled actuators to simulate and modulate UAV-induced airflow under three regimes: Limited airflow (LA), natural airflow (NA) and UAV-induced airflow (UA). Computational fluid dynamics (CFD) simulations validated the aerodynamic performance and uniformity of airflow distribution, while field experiments quantified microclimatic parameters (temperature, wind speed and turbulence intensity), photosynthetic activity, nitrogen dynamics and yield components at key phenological stages and time intervals (9:00 AM, 12:00 PM, 3:00 PM). Results demonstrate that the IMAMS effectively stabilised root-zone and canopy temperatures, reducing diurnal temperature fluctuations by 33% and 48%, respectively, and enhanced turbulence intensity in the phyllosphere (0.355–0.390), promoting gas exchange and increasing photosynthetic efficiency by 18%. These microclimate improvements facilitated enhanced nitrogen assimilation and translocation, resulting in a grain yield of 43.2 g plant⁻¹, representing a 91% and 23% increase over LA and NA treatments, respectively, and improving the harvest index to 37.24%.

Polyamines (PAs) are low molecular weight defensive molecules with a prominent role in abiotic stress reactions. This study investigated the role of polyamines in the adaptive response of <i>Ae.b.</i> 382 to PEG-induced osmotic stress by investigating the effects of exogenous polyamines and their biosynthesis inhibitors on root architecture, polyamine levels and related gene expression profiles. The two-day-long 33 mM PEG treatment induced strong physiological changes, resulting in alterations in root robusticity. The simultaneous application of PA inhibitors strongly reduced root fresh weight (FW), length and surface, disrupting the process of adaptive thickening. However, additions of exogenous spermidine, spermine or a combined PA mix were able to counteract the negative effects of the inhibitors or activate defensive measures. The results on polyamine content and gene expressional profiling confirmed our hypothesis that polyamines are one of the key compounds in drought stress adaptation responses of <i>Ae.b.</i> 382.

The experiment was conducted in a greenhouse using a dry-down and rewatering protocol, followed by validation under field conditions across two growing seasons, 2023 and 2024. Eight lines were grown in a greenhouse where pots were sealed to prevent evaporation, and plants were allowed to gradually transpire the full amount of water in each pot before being re-watered. The fraction of transpirable soil water (FTSW) and normalised transpiration rate (NTR) were monitored using a gravimetric method for all lines. Physiological parameters including stomatal conductance, transpiration rate, and quantum yield of fluorescence (ΦPSII) were recorded. Flower numbers and wilting scores were recorded daily, and pod numbers were assessed at harvest. Significant genotypic variation was observed in response to water-deficit stress. PI506862 and PI423926 exhibited a strong stress adaptive response of early stomatal closure with high FTSW thresholds of 0.65 and 0.69, respectively, lower wilting scores, and rapid transpiration and ΦPSII activity during the rewatering recovery phase. PI506862 had high flower retention and pod setting during the recovery phase in greenhouse (17 pods/plant) and field trials (up to 146–193 pods/plant). In contrast, PI567638 had the lowest FTSW threshold (0.43), highest wilting scores, and poor recovery (4 out of 5 plants did not survive the dry-down phase) and failed to produce pods after rewatering.

We discovered that 5-ALA unexpectedly accelerated plant wilting and mortality.

To address this challenge, we developed a standardised PhotoBiology Station (PBS) for studies on the complexities of plant–light interactions under field conditions. The station features five levels of shade and three replicates arranged in a randomised block design. The black shade nets linearly and significantly reduced the photosynthetically active radiation across shade levels. Spectral analysis revealed a consistent reduction in photon irradiance across the blue, green, red and far-red spectral bands, with a decrease in the blue/green ratio while maintaining a stable red/far-red ratio. Microclimatic conditions, including temperature and relative humidity, were also affected. Soybean seedlings exhibited typical shade-avoidance responses, such as increased stem height, coupled with reduced stem diameter. Multivariate analyses indicated that the blue light band acts as a signal that triggers plant responses to shade under the black shade net. These findings validate PBS as an effective platform for studying shading effects and plant–light interactions under open-air conditions and overcome critical methodological challenges, such as pseudoreplication.
