Utilizing unmanned aerial vehicle (UAV) remote sensing, this study explored the applicability of an empirical crop water stress index (CWSI) based on canopy temperature and three-dimensional drought indices (TDDI) constructed from surface temperature (), air temperature () and five vegetation indices (VIs) for monitoring the moisture status of dryland crops. Three machine learning algorithms (random forest regression [RFR], support vector regression, and partial least squares regression) were used to compare the performance of the drought indices for vegetation moisture content (VMC) estimation in sorghum and maize. The main results of the study were as follows: (1) Comparative analysis of the drought indices revealed that --Normalized Difference Vegetation Index (TDDIn) and --Enhanced Vegetation Index (TDDIe) were more strongly correlated with VMC compared with the other indices. The indices exhibited varying sensitivities to VMC under different irrigation regimes; the strongest correlation observed was for the TDDIe index with maize under the fully irrigated treatment (=−0.93); (2) Regarding spatial and temporal characteristics, the TDDIn, TDDIe and CWSI indices showed minimal differences over the experimental period, with coefficients of variation were 0.25, 0.18 and 0.24, respectively. All three indices were capable of effectively characterizing the moisture distribution in dryland maize and sorghum crops, but the TDDI indices more accurately monitored the spatial distribution of crop moisture after a rainfall or irrigation event. (3) For prediction of the moisture content of single crops, RFR models based on TDDIn and TDDIe estimated VMC most accurately (0.7), and the TDDIn-based model predicted VMC with the highest accuracy when considering multiple-crop samples, with and RMSE of 0.62 and 14.26%, respectively.

Also, modulating source-sink relationships through crop management has been used to improve crop productivity. This study aims to investigate whether and how modifying leaf colour alters source-sink relationships and whether current crop cultivation practices remain applicable for leaf-colour modified genotypes. Periodically collected data of total biomass and nitrogen (N) accumulation in rice genotypes of four genetic backgrounds and their leaf-colour modified (greener or yellower) variants were analysed, using a recently established model method to quantify the source-sink (im)balance during grain filling. Among all leaf-colour variants, only one yellower-leaf variant showed higher source capacity than its normal genotype. This was associated with increased post-flowering N-uptake that prolonged functional leaf-N duration, and this increased post-flowering N-uptake was possible because of reduced pre-flowering N-uptake. The density experiment showed that current management practices (insufficient planting density accompanied with abundant N application) were unsuitable for the yellower-leaf genotype, ultimately limiting its yield potential. Leaf-colour modification affects source-sink relationships by regulating N trade-off between pre-flowering and post-flowering uptake, and N translocation between source and sink organs. To best exploit leaf-colour modification for an improved crop productivity, adjustments of crop management practices are required.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140070004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The correlation analysis between six root morphological traits revealed a strong positive correlation of TRL with RSA, RV with RSA and AvgD, whereas a significant negative correlation between TRL and AvgD. Subsequently, a genome-wide association study (GWAS) was performed using the root phenotypic data and genotypic data reported previously for 242 accessions using 56,010 single nucleotide polymorphisms (SNPs) from the CottonSNP80K array.

However, it can also exacerbate problems such as wheat floret degeneration, leading to reduced yields. Therefore, investigating wheat floret degeneration mechanisms under low nitrogen stress and identifying mitigation measures are conducive to achieving high yields and sustainable development. To investigate the physiological mechanism of low nitrogen stress affecting wheat floret degradation and whether exogenous brassinosteroids can alleviate this stress, three nitrogen application rates (N0, no nitrogen application; N1, 120 kg ha pure nitrogen; and N2, 240 kg ha pure nitrogen) and exogenous spraying experiments (N0CK, no nitrogen with water spraying; N0BR, no nitrogen with 24-epibrassinolide (an active brassinosteroids) spraying; and N1, 120 kg ha pure nitrogen with water spraying) were designed. The results indicated that low nitrogen stress induced a large amount of reactive oxygen species generation. Although wheat spikes synthesized flavonoids to combat oxidative stress, their energy metabolism (glycolysis and tricarboxylic acid cycle) and ascorbate-glutathione cycle were inhibited, keeping reactive oxygen levels elevated within the spike, inducing cell death and exacerbating floret degeneration. Furthermore, brassinosteroids played a role in regulating wheat floret degeneration under low-nitrogen stress. Exogenous foliar spraying of 24-epibrassinolide promoted energy metabolism and the ascorbate-glutathione cycle within the spike, enhancing energy charge and effectively mitigating a portion of reactive oxygen induced by low nitrogen stress, thereby alleviating floret degeneration caused by low nitrogen stress. In summary, low-nitrogen stress disrupts the redox homeostasis of wheat spikes, leading to floret degeneration. Brassinosteroids alleviate floret degeneration by improving the redox state of wheat spikes. This research provides theoretical support for balancing the contradiction between high yields and sustainable development and is beneficial for the application of low nitrogen in production.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140070172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the recognized importance of pectin methylesterification in seed germination, the specific mechanisms that govern this process remain unclear. In this study, we demonstrated that the overexpression of is associated with a decrease in PME activity and an increase in pectin methylesterification. This leads to the softening of the cell wall in seeds, which positively regulates cotton seed germination. AtPMEI19, the homologue in , plays a similar role in seed germination to GhPMEI53, indicating a conserved function and mechanism of PMEI in seed germination regulation. Further studies revealed that GhPMEI53 and AtPMEI19 directly contribute to promoting radicle protrusion and seed germination by inducing cell wall softening and reducing mechanical strength. Additionally, the pathways of ABA and GA in the transgenic materials underwent significant changes, suggesting that GhPMEI53/AtPMEI19-mediated pectin methylesterification serves as a regulatory signal for the related phytohormones involved in seed germination. In summary, GhPMEI53 and its homologs alter the mechanical properties of cell walls, influencing the mechanical resistance of the endosperm or testa. Moreover, they impact cellular phytohormone pathways (e.g., ABA, GA) to regulate seed germination.

In this study, 24 grain soybean varieties from low-latitude regions (22-31°N) were introduced to the high-latitude northwestern Loess Plateau (39°N) between 2018 and 2019. The growth phenotypes were observed, and their forage productivity potential was assessed. All varieties displayed delayed flowering following cross-latitude introduction, with the vegetative growth phase of some varieties even exceeding their entire growth duration at their origin. Rapid dry matter accumulation rates were indicative of growth adaptation performance and formed the basis for soybean forage yield. Varieties from the tropical south China region exhibited significant yield advantages, with dry matter yields of 8.97-14.68 t ha and crude protein yields of 1.44-2.51 t ha. Varieties HX3 and GX7, originating from this region, demonstrated optimal growth adaptability and productivity in the cross-latitude environment, achieving the highest dry matter yields of 14.68 and 13.86 t ha, respectively. As a result, HX3 and GX7 are recommended for local farming systems to provide high-quality forage.

To assess the effect of tilling and fertilization practices in the wheat-maize cropping systems, we carried out a three-year field experiment designed to quantify the carbon footprint (CF), and energy efficiency of the cropping systems in the North China Plain. As the study parameters, we used four tillage practices (no tillage (NT), conventional tillage (CT), rotary tillage (RT) and subsoiling rotary tillage (SRT)), and two fertilizer regimes (inorganic fertilizer (IF), and hybrid fertilizer with organic and inorganic components (HF)). Our results indicated that the most prominent energy inputs and greenhouse gas (GHG) emissions could be ascribed to the use of fertilizers and fuel consumption. Assuming the same fertilization regime, ranking the tillage patterns with respect to the value of the crop yield, the profit, the CF, the energy use efficiency (EUE) or the energy productivity (EP) for either wheat or maize always gave the following result: SRT>RT>CT>NT. For the same tillage, the energy consumption associated with HF was higher than IF, but its GHG emissions and CF were lower while the yield and profit were better. In terms of the overall performance, tilling is more beneficial than NT, and reduced tillage (RT and SRT) are more beneficial than CT. The fertilization regime with the best overall performance was HF. Combining SRT with HF has significant potential for reducing CF and increasing EUE, improving the sustainability. Adopting measures promoting these optimizations can help overcome the challenges posed by lack of food security, energy crises and ecological stress.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140056857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we conducted experiments using different sowing dates, that is, conventional sowing date 1 (CS1), CS2 (10 d later than CS1), DS1 (30 d later than CS1), and DS2 (30 d later than CS2), and three rice varieties, i.e., “Yixiangyou 2115,” “Fyou 498,” and “Chuanyou 6203.” This experiment was conducted at four sites in the Sichuan basin in 2018 and 2019 to evaluate the influence of DS on the pasting properties of rice, which are a proxy for eating and cooking quality (ECQ). In DS1 and DS2, rice had a significantly greater amylose content (AC) but a lower protein content (PC), peak viscosity (PKV), cool paste viscosity (CPV), and hot paste viscosity (HPV) than in CS1 and CS2. Moreover, with the exception of CS2 and DS1 in 2018, DS1 and DS2 led to a 2.15–11.19% reduction in breakdown viscosity (BDV) and a 23.46–108.47% increase in setback viscosity (SBV). However, the influence of DS on rice pasting properties varied by study site and rice variety. In 2019, DS1 and DS2 led to a BDV reduction of 2.35–9.33, 2.61–8.61, 10.03–17.78, and 2.06–8.93%, and a SBV increase of 2.32–60.93, 63.74–144.24, 55.46–91.63, and -8.28–65.37% at the Dayi, Anzhou, Nanbu, and Shehong, respectively. DS resulted in a greater decrease in PKV, HPV, CPV, and BDV and a greater increase in the AC and SBV for Yixiangyou 2115 than for Chuanyou 6203 and Fyou 498. Correlation analysis indicated that PKV and HPV were significantly and positively related to the mean, maximum, and minimum temperatures after heading. These temperatures have to be greater than 25.9, 31.2, and 22.3℃ to increase the relative BDV and decrease the relative SBV of rice, thereby enhancing ECQ. In conclusion, DS might contribute to a significant deterioration in ECQ in machine-transplanted rice in the Sichuan basin. A mean temperature above 25.9℃ after heading is required to improve the ECQ of rice.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140057081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
