    Effects of Chlorine-Based Fertilizers on Tomato Growth under Soilless Culture

    Fei Li1,2, Meili Ding1, Hui Yuan1, Siping Wang1, Bin Liang2,*

    Phyton-International Journal of Experimental Botany, Vol.94, No.1, pp. 243-250, 2025, DOI:10.32604/phyton.2025.059499 - 24 January 2025

    Abstract This study investigated the effects of chlorine-based fertilizers under varying nitrogen solution concentrations in a soilless culture system. The experiment included four nitrogen solution concentration levels, with nitrogen concentrations of 6 mmol/L (C1), 12 mmol/L (C2), 18 mmol/L (C3), and 24 mmol/L (C4). Each nutrient concentration level was further divided into four chloride ion treatments (R1, R2, R3, and R4), where 100%, 60%, 33%, and 0% of the NH4+ and K+ ions were derived from NH4Cl and KCl, respectively. The length, surface area and volume of root were significantly higher by 25.3%~136.9%, 40.1%~173.1%, 27.9%~178.0%, respectively, in the… More >

    Phyton-International Journal of Experimental Botany, Vol.93, No.12, pp. 3589-3616, 2024, DOI:10.32604/phyton.2024.057881 - 31 December 2024

    Abstract Drought stress (DS) and overuse of chemical fertilizers cause considerable losses in the agro-physiological as well as biochemical performance of plants. In this context, considerable effort will be required to replace chemical fertilizers (NPK) with biostimulants as an important approach to enhance the productivity and sustainability of agriculture. Here, we evaluated the effect of separating and/or combining arbuscular mycorrhizal fungi (AMF) with compost (C) in comparison to the use of NPK on the growth, physiological and biochemical of tomatoes under DS. The findings showed that DS significantly reduced the growth and physiological attributes of tomatoes.… More >

    Zhancai Zhan1, Penghang Ling1, Wugui Jiang1,*, Tao Chen1, Qinghua Qin2,3, Longhui Mao1

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.32, No.2, pp. 1-1, 2024, DOI:10.32604/icces.2024.011400

    Abstract In the intricate and multi-physical process of Laser Powder Bed Fusion (LPBF), the microstructure significantly influences the performance of the resulting components, particularly evident in the manufacturing of thin-walled structures. In this paper, a prediction model of microstructure evolution coupled with 3D cellular automaton (CA) and finite element (FE) method for thin-walled components of GH4169 fabricated by LPBF is established. In this model, the multi-layer and multi-track temperature field within the interest region of thin-walled parts is simulated by the FE method. Subsequently, the temperature history is transferred to the CA model for predicting the… More >

    The Integration of Water and Fertilizer Regulated Soil Nutrients and Enzyme Activities of Greenhouse Tomato (Solanum lycopersicum) by Moistube Irrigation

    Haijian Yang1, Mingzhi Zhang1,*, Na Xiao1, Yuan Li2

    Phyton-International Journal of Experimental Botany, Vol.93, No.11, pp. 2813-2836, 2024, DOI:10.32604/phyton.2024.057795 - 30 November 2024

    Abstract Moistube irrigation was driven by the gradient of water potential inside and outside the pipe wall, which has the advantages of continuous irrigation during the crop growth period. However, the response mechanism of soil nutrients and enzyme activities of greenhouse tomatoes under the integration of water and fertilizer by moistube irrigation is still unclear. In order to explore the changes in soil nutrients and enzyme activities of greenhouse tomatoes regulated by irrigation and fertilization in moistube irrigation greenhouse, a completely randomized experimental design was conducted to explore the effects of different irrigation amounts (I, controlling… More >

    Abstract Tomato (Solanum lycopersicum) is a perishable fruit because of its fast water loss and susceptibility to pathogens in the post-harvest stage, which leads to huge economic losses every year. In this study, firstly from 19 tomato cultivars, we screened out two cultivars, Riogrand and SalarF1, having long and short shelf-life spans, respectively. Secondly, shelf-life analysis was carried out for both cultivars at room temperature. Results exhibited that Riogrand showed higher firmness and less weight loss than SalarF1. The ethylene production was higher in SalarF1, compared with Riogrand during post-harvest storages. We performed transcriptomic analysis of both… More >

    Response of Bacterial Community and Enzyme Activity of Greenhouse Tomato under Different Irrigation Systems

    Abstract The micro-sprinkler irrigation mulched (MSM) has been suggested as a novel water-saving approach in controlled environment agriculture. However, the effects of microbial community structure and enzyme activity in the rhizosphere soil on crop growth under MSM remain unclear. This study conducted a randomized experimental design using greenhouse tomatoes to investigate changes in bacterial community structure and enzyme activity in rhizosphere soil under different irrigation frequencies (F) and amounts (I) of MSM. The findings revealed that with the increase of F or I, The total count of soil bacteria in tomatoes first rose and then fell… More >

    Zhengfeng Lai, Dongmei Lian, Shaoping Zhang, Yudong Ju, Bizhen Lin, Yunfa Yao, Songhai Wu, Jianji Hong, Zhou Li*

    Phyton-International Journal of Experimental Botany, Vol.93, No.6, pp. 1143-1158, 2024, DOI:10.32604/phyton.2024.051207 - 27 June 2024

    Abstract The cytokinin oxidase/dehydrogenase (CKX) enzyme is essential for controlling the fluctuating levels of endogenous cytokinin (CK) and has a significant impact on different aspects of plant growth and development. Nonetheless, there is limited knowledge about CKX genes in tomato (Solanum lycopersicum L.). Here we performed genome-wide identification and analysis of nine SlCKX family members in tomatoes using bioinformatics tools. The results revealed that nine SlCKX genes were unevenly distributed on five chromosomes (Chr.1, Chr.4, Chr.8, Chr.10, and Chr.12). The amino acid length, isoelectric points, and molecular weight of the nine SlCKX proteins ranged from 453 to 553, 5.77… More >

    Phyton-International Journal of Experimental Botany, Vol.93, No.6, pp. 1311-1323, 2024, DOI:10.32604/phyton.2024.049535 - 27 June 2024

    Abstract From economic and nutritional points of view, tomato is, historically, considered one of the most important crops. Without significant yield reduction, most commercial cultivars of tomato crops are sensitive to moderate levels of salinity. However, high levels of salt stress can negatively affect the yield and quality of tomato fruits. Therefore, this study was conducted to evaluate the yield and fruit quality of three tomato cultivars (Forester, Ghandowra-F1, and Feisty-Red) cultivated hydroponically, under three different levels of nutrient solution salinity. Evaluation of tomato fruits was performed based on quantity (number and weight of fruits, and… More >

    Ankita Gangwar1, Vijaypal Singh Dhaka1, Geeta Rani2,*, Shrey Khandelwal1, Ester Zumpano3,4, Eugenio Vocaturo3,4

    CMC-Computers, Materials & Continua, Vol.79, No.1, pp. 117-142, 2024, DOI:10.32604/cmc.2024.048119 - 25 April 2024

    Abstract A consumption of 46.9 million tons of processed tomatoes was reported in 2022 which is merely 20% of the total consumption. An increase of 3.3% in consumption is predicted from 2024 to 2032. Tomatoes are also rich in iron, potassium, antioxidant lycopene, vitamins A, C and K which are important for preventing cancer, and maintaining blood pressure and glucose levels. Thus, tomatoes are globally important due to their widespread usage and nutritional value. To face the high demand for tomatoes, it is mandatory to investigate the causes of crop loss and minimize them. Diseases are… More >

    Naeem Ullah1, Javed Ali Khan2,*, Sultan Almakdi3, Mohammed S. Alshehri3, Mimonah Al Qathrady4, Eman Abdullah Aldakheel5,*, Doaa Sami Khafaga5

    CMC-Computers, Materials & Continua, Vol.77, No.3, pp. 3969-3992, 2023, DOI:10.32604/cmc.2023.041819 - 26 December 2023

    Abstract Tomato leaf diseases significantly impact crop production, necessitating early detection for sustainable farming. Deep Learning (DL) has recently shown excellent results in identifying and classifying tomato leaf diseases. However, current DL methods often require substantial computational resources, hindering their application on resource-constrained devices. We propose the Deep Tomato Detection Network (DTomatoDNet), a lightweight DL-based framework comprising 19 learnable layers for efficient tomato leaf disease classification to overcome this. The Convn kernels used in the proposed (DTomatoDNet) framework is 1 × 1, which reduces the number of parameters and helps in more detailed and descriptive feature extraction for… More >
