    Abstract The 3-dimensional (3D) modeling of crop canopies is fundamental for studying functional-structural plant models. Existing studies often fail to capture the structural characteristics of crop canopies, such as organ overlapping and resource competition. To address this issue, we propose a 3D maize modeling method based on computational intelligence. An initial 3D maize canopy is created using the t-distribution method to reflect characteristics of the plant architecture. The subsequent model considers the 3D phytomers of maize as intelligent agents. The aim is to maximize the ratio of sunlit leaf area, and by iteratively modifying the azimuth angle of the 3D phytomers, a 3D maize canopy model that maximizes light resource interception can be constructed. Additionally, the method incorporates a reflective approach to optimize the canopy and utilizes a mesh deformation technique for detecting and responding to leaf collisions within the canopy. Six canopy models of 2 varieties plus 3 planting densities was constructed for validation. The average

    Abstract The microphenotype plays a key role in bridging the gap between the genotype and the complex macro phenotype. In this article, we review the advances in data acquisition and the intelligent analysis of plant microphenotyping and present applications of microphenotyping in plant science over the past two decades. We then point out several challenges in this field and suggest that cross-scale image acquisition strategies, powerful artificial intelligence algorithms, advanced genetic analysis, and computational phenotyping need to be established and performed to better understand interactions among genotype, environment, and management. Microphenotyping has entered the era of Microphenotyping 3.0 and will largely advance functional genomics and plant science.

    Abstract Brassinolides (BRs) are naturally-occurring phytohormones, which are essentially important to improve the crop adoptive capacity to various stresses. Spray volume (SV) and agrochemical application methods are associated with chemical deposition and field efficiency. The objective of this study was to compare the possible effects of 28-Homobrassinolide (HBL) dosages 18, 22, and 30 mg a.i. ha⁻¹ for unmanned aerial vehicle (UAV) sprayers (15 L ha⁻¹ and 30 L ha⁻¹) and 22 mg a.i. ha⁻¹ for Knapsack manual sprayers (KMS) (450 L ha⁻¹) at maize silking stage on droplets deposition distribution, photosynthetic parameters, grain filling process and yield. The results showed that the droplet deposition of UAV (15, 30 L ha⁻¹) was 47.04%, 8.89% higher than KMS. However, the UAV sprayer had a poor droplet deposition distribution. HBL significantly increased the photosynthetic parameters, grain filling rate, and yield. A UAV spray volume of 15 L ha⁻¹ with 22 mg a.i. ha⁻¹ significantly increased grains yield by 4.16–5.64%, 7.5–12.09% compared to KMS and CK in both years. Considering the high efficiency of the UAV sprayer and better effects of HBL on final yield, spraying 22~30 mg a.i. ha⁻¹ with UAV spray volume 15 L ha⁻¹ at the silking stage could be a better strategy.

    Abstract Real-time monitoring of canopy chlorophyll content is significant in understanding crop growth status and guiding precision agricultural management. Remote sensing methods have demonstrated great potential in this regard. However, the spatiotemporal heterogeneity of chlorophyll content within crop canopies poses challenges to the accuracy and stability of remote sensing estimation models. Hence, this study aimed to develop a novel method for estimating canopy chlorophyll content (represented by SPAD values) in maize (

    Abstract Two aerobic, Gram-staining-positive, rod-shaped, endospore-forming, thermophilic bacterial strains, designated FJAT-47801ᵀ and FJAT-47835, were isolated from the sediment collected from Zhangjiang Estuary Mangrove National Nature Reserve in Fujian Province, China. Growth was observed at 25–55 °C (optimum, 50 °C) and pH 7.0–9.0 (optimum, pH 7.0), with up to 4.0% (w/v) NaCl (optimum, without NaCl). Strains FJAT-47801ᵀ and FJAT-47835 showed the highest 16S rRNA gene sequence similarity to Bacillus oleivorans (98.5%). The 16S rRNA gene sequence similarity between FJAT-47801ᵀ and FJAT-47835 was 99.9% indicating they were the same species. Phylogenetic (based on 16S rRNA gene sequences) and phylogenomic (based on 120 conserved bacterial single-copy genes) trees showed that strains FJAT-47801ᵀ and FJAT-47835 should be affiliated to the genus Bacillus. The of menaquinone of strain FJAT-47801ᵀ was MK-7. The major fatty acids of strain FJAT-47801ᵀ were iso-C₁₅:₀, anteiso-C₁₅:₀, iso-C₁₇:₀, and C₁₆:₀. The major polar lipids strain FJAT-47801ᵀ were phosphatidylethanolamine (PE), diphosphatidylglycerol (DPG), and phosphatidylglycerol (PG). The genomic DNA G+C content of strain FJAT-47801ᵀ was 39.3%. The average nucleotide identity (84.3%) and the digital DNA–DNA hybridization value (28.1%) between strain FJAT-47801ᵀ and B. oleivorans CCTCC AB 2013353ᵀ were below the cut-off level for species delineation. Based on the above results, strain FJAT-47801ᵀ represents a novel species of the genus Bacillus, for which the name Bacillus litorisediminis sp. nov., is proposed. The type strain is FJAT-47801ᵀ (=GDMCC 1.2712ᵀ = JCM 34875ᵀ).

    Abstract Drought stress caused by insufficient irrigation or precipitation impairs agricultural production worldwide. In this study, a two-year field experiment was conducted to investigate the effect of coronatine (COR), a functional analog of jasmonic acid (JA), on maize drought resistance. The experiment included two water treatments (rainfed and irrigation), four COR concentrations (mock, 0 μmol L⁻¹; A1, 0.1 μmol L⁻¹; A2, 1 μmol L⁻¹; A3, 10 μmol L⁻¹) and two maize genotypes (Fumin 985 (FM985), a drought-resistant cultivar and Xianyu 335 (XY335), a drought-sensitive cultivar). Spraying 1 μmol L⁻¹ COR at seedling stage increased surface root density and size, including root dry matter by 12.6%, projected root area by 19.0%, average root density by 51.9%, and thus root bleeding sap by 28.2% under drought conditions. COR application also increased leaf area and SPAD values, a result attributed to improvement of the root system and increases in abscisic acid (ABA), JA, and salicylic acid (SA) contents. The improvement of leaves and roots laid the foundation for increasing plant height and dry matter accumulation. COR application reduced anthesis and silking interval, increasing kernel number per ear. COR treatment at 1 μmol L⁻¹ increased the yield of XY335 and FM985 by 7.9% and 11.0%, respectively. Correlation and path analysis showed that grain yields were correlated with root dry weight and projected root area, increasing maize drought resistance mainly via leaf area index and dry matter accumulation. Overall, COR increased maize drought resistance mainly by increasing root dry weight and root area, with 1 μmol L⁻¹ COR as an optimal concentration.

    Abstract Maize (Zea mays L.) lodging is an important factor limiting its yield increase worldwide. EDAH (containing 27% ethephon and 3% DA-6) is commonly used to decrease lodging. There is an urgent need to select efficient application methods of agrochemical for better spray deposition. In our research, an unmanned aerial vehicle (UAV) (15 L ha⁻¹ and 30 L ha⁻¹) with EDAH dosages of 72 and 90 g a.i. ha⁻¹, and electric knapsack sprayers (EKS) (450 L ha⁻¹) with dosages of 90 g a.i. ha⁻¹ were used to compare the droplet deposition distribution, uniformity and maize growth. According to our research, EDAH applied by UAV had a higher droplet deposition rate than EKS; EKS had a higher droplet coverage rate, deposition density, droplet distribution uniformity. At the same dosage of EDAH, the UAV had a better effect on controlling maize growth than EKS, and almost equal effects were detected when the dosage applied by the UAVs was decreased by 20%. Considering the lodging occurrence and yield, we recommend that the dosage of EDAH applied by UAVs should be 72 g a.i. ha⁻¹ when there is weak lodging and 90 g a.i. ha⁻¹ when there is heavy lodging, with a spray volume of 15 L ha⁻¹.

    Abstract Brassinolides are plant-specific Polyhydroxylated steroid hormones that play a vital role in plant growth regulation and actively participate in inducing various stress tolerance. Our objective was to investigate the influence of 28-Homobrassinolide (HBR) dosages and compare the droplet deposition of unmanned aerial spraying system (UASS) with electric air-pressure knapsack (EAP) sprayer over the wheat field. Three HBR dosages (19, 24, 30 mg a. i. ha⁻¹) with spray volume (SV) of 15, 30 L ha⁻¹ were applied by UASS, and HBR dosage of 24 mg a. i. ha⁻¹ with a spray volume of 450 L ha⁻¹ was applied by EAP. The droplet deposition of UASS 15 L ha⁻¹ was 15.51 %, 33.57 % higher than UASS 30 L ha⁻¹ and EAP. While spray distribution uniformity in both UASS spray volumes was less than EAP. HBR (24, 30 a. i. mg ha⁻¹) significantly increased the photosynthetic traits, which led to a hastened grain filling rate and increased biomass of reproductive plant organs, yield, and yield components. HBR dosage of 24 mg a. i. ha⁻¹ with a spray volume of 15 L ha⁻¹ significantly increased grain yield by 17.94 %, 16.31 % than CK and 12.13 %, 15.31 % than EAP in two years, respectively. It is concluded that the application of HBR 24 ∼ 30 mg a. i. ha⁻¹ with UASS 15 L ha⁻¹ at the wheat anthesis stage could be an effective approach to improve the wheat yield.
