As expected, the biomass production of most of the 12 wild germplasm populations was low in comparison with the cultivar controls. However, key relationships between root structure and both plant persistence and plant production were identified, with plants having either an expansive or compact root system or a mixture of both. This study explored wild germplasm material and highlights the potential genetic variation available within germplasm collections. As this is one of a few publications that look at both below- and above-ground traits, it also highlights the benefits of finding the right balance between root systems.

The results showed that whole-growth-duration warming did not affect early rice yield but significantly decreased late rice yield, which was caused by the decreased grain weight that may be related to the reduced translocation of dry matter accumulated during the pre-heading phase under warming. Whole-growth-duration warming improved the milling quality of late rice but decreased that of early rice; however, the chalky rice rate and chalkiness degree were increased by 20.7% and 33.9% for early rice, and 37.6% and 51.6% for late rice under warming, respectively. We found that the crude protein content of milled rice was significantly increased by warming in both early and late rice, which would result in the deterioration of eating quality. Besides, compared with the control treatment, the setback of late rice was significantly reduced by 17.8% under warming, while that of early rice was not significantly affected by warming. These results suggest that the negative impacts of whole-growth-duration warming on grain quality varied between early rice and late rice to some extent.

The present study investigates spring frost tolerance in sets of bread wheat and barley accessions, with experiments conducted over a period of 2 years. In both species, the occurrence of spring frost during the flowering stage resulted in a reduction in grain yield, manifested as a decrease in the number of grains and a concomitant reduction in grain size. In barley, an additional association was observed between yield reduction and a decline in the number of tillers and heads following freezing. The detrimental effects of spring frost can be amplified when low temperatures are followed by drought. When water availability is not limited, plants begin to establish new heads, which in the case of wheat may partially compensate for decreasing yield. However, the practical impact of this effect may be limited by unequal maturity.

The experimental design included well-watered (WW 80% watering), drought stress (DS, 20% watering) salinity stress (SS, 0 control and 13 dS m⁻¹), boron toxicity (Na₂O₅B₂O₃.10H₂O, at different doses of 0 and 8 mg L⁻¹) and re-watering after a long-term period of drought stress (24 days). The well-irrigated (80% WW) treatment, which included all factors as a the non-stressed control treatment during the experiment was carried out with five replications. Morphological, physiological and biochemical analyses of plants were measured at four time points: at the 10th and 24th days after the onset of the drought stress period and after re-watering, at 2nd and 7th days following. The relative membrane permeability was increased and relative water content was decreased because drought and salinity stress limited water availability and caused an imbalance in the water status of the leaves and stem of the plant. Even though high levels of Na⁺ and Cl⁻ ions interfered with essential nutrient uptake under drought stress and boron application, Ca⁺² ion levels in the leaves significantly increased in the leaves of plants in areas treated with drought, salt, and boron after re-watering. Extended or intense drought and salinity conditions harmed the phloem and xylem tissue cells of the stem by changing cell size and density, which in turn disrupted biochemical processes, including the functioning of water channels under challenging circumstances. Particularly under conditions of salt and drought stress, the vascular bundles in the plant stem were observed to either shrink significantly or assume an irregular shape. Long-term drought reduced relative water content (RWC) values, resulting in plant dehydration and increased osmotic pressure (RMP) in leaf cells, further exacerbated by salinity and drought stress. The plant attempted to regain some of its characteristics in response to these severe stress conditions after re-watering. However, 24 days after the long dry period, even if watering was re-applied, the growth power of the plant was reduced due to the disturbance in membrane permeability as a result of excessive cell damage.</p>\u0000 </div>","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":"211 2","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666060","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}

Key enzymes, including α-amylase (<i>AMY1</i> and <i>AMY2</i>), hexokinase (<i>HXK1</i>) and sucrose-phosphate synthase (SPS), facilitate carbohydrate mobilisation during germination, fueling glycolysis, the tricarboxylic acid (TCA) cycle and the pentose phosphate pathway (PPP).

Using the entropy weighting method (EWM) and coefficient of variation method (CV), comprehensive growth indices, CGMI_EWM and CGMI_CV, were developed. These indices were correlated with 10 vegetation indices to select those with significant relevance. Subsequently, three machine learning methods—partial least squares (PLS), random forest (RF) and particle swarm optimisation-enhanced random forest (PSO-RF)—were utilised to construct models for inversely monitoring maize growth. The optimal model was determined through evaluative metrics, leading to the acquisition of spatial distribution information on maize growth within the study area. The results indicate that the CGMI_EWM derived from the entropy weight method shows a higher correlation than individual indices, significantly enhancing model precision over traditional single-index monitoring.

In Northeast China, a major grain-producing region, the Maize–Soybean rotation is crucial for sustainable agricultural development. However, previous studies have mainly focused on single crops and lacked attention to soil health and regional scale analysis. This study utilises the APSIM model to predict crop yields and soil organic carbon (SOC) under two Representative Concentration Pathways 4.5 and 8.5 (RCP4.5 and RCP8.5) future climate scenarios in different latitude regions of Northeast China. The result shows that climate change has significant spatial and temporal variations on crop yield and soil organic carbon storage in the Maize–Soybean rotation system. Compared to the baseline (1980–2010), maize yields change from −11.6 to 42.8 kg 10a⁻¹ (RCP4.5) and 7.1 to 39.8 kg 10a⁻¹ (RCP8.5), and soybean yields vary from −13.1 to 3.9 kg 10a⁻¹ (RCP4.5) and −16.2 to −5.6 kg 10a⁻¹ (RCP8.5). SOC increases slowly from 0 to 20 cm and decreases from 20 to 40 cm, resulting in a decrease of 21–334 kg ha⁻¹ 10a⁻¹ (RCP4.5) and 26–280 kg ha⁻¹ 10a⁻¹ (RCP8.5) in predicted future soil organic carbon storage. PLS-PM results show that future precipitation change has a negative impact on SOC accumulation, and temperature rise in the RCP8.5 scenario has a negative impact on SOC storage. SOC storage is positively correlated with crop yields, and the correlation is stronger under RCP8.5, which has a higher explanation for crop yields changes. Climate change significantly affects crop yields and SOC stocks in the Maize–Soybean rotation system of Northeastern China, especially during extreme weather.
