The development of women farmers in rural areas is fostered through a group forum. To strengthen the institution of the Women Farmers group and focus on coaching, the implementation of the activity was carried out at the Mabi Subak Hall, Belantih Village. It began with a Coordination Meeting of the Farmer Women Group which was opened by the head of Belantih Village who was accompanied by the head of Banjar Mabi hamlet. The Women's Farm Workers Group (KWBT) is an agricultural institution created with the aim of facilitating the activities of women agricultural workers from the orange plant maintenance sector, farm worker equipment assistance, capital to innovation in processing post-harvest orange products into innovative products that have a selling value.

Implementation of AlexNet and Xception Architectures for Disease Detection in Orange Plants

Oranges are one of Indonesia's primary horticultural commodities, with production increasing each year. However, pest and disease infestations often go undetected, leading to significant reductions in crop yields. This study implements Convolutional Neural Network (CNN) technology to identify diseases in orange plants using two architectures: AlexNet and Xception. The implementation results show that the Xception architecture achieved a high accuracy of 96% after 100 training epochs, indicating its effectiveness in disease detection tasks. This research highlights the potential of integrating CNN technology, particularly the Xception model, into web-based systems for disease detection in orange plants. Such systems can assist farmers in maintaining crop health, improving productivity, and ensuring harvest quality.

Alternative substrates for the production of container-grown Mexican marigold

ABSTRACT Objective: To evaluate substrate mixtures for the production of Mexican marigolds grown in containers in the community of Santa Cruz Itundujia, Oaxaca. Methods: Four soil mixtures were tested: 1) 70% ocote pine needles + 30% soil, 2) 70% leaf mold + 30% soil, 3) 70% river sand + 30% soil, and 4) 70% sawdust + 30% soil. Mexican marigold (Tagetes erecta) var. Inca II Deep Orange plants were established in pots under open field conditions. Height, number of leaves, plant width, branching, leaf area, and number of buds were evaluated in the different phenological stages of the plant; the last measurement was made at the flowering stage. Soil fertility parameters were analyzed, and physical analysis of the substrates was performed. Results: The treatments produced differential results; ocote pine needles + soil and leaf mold + soil were the best for producing container-grown marigolds. The lowest results in yield variables were found with the river sand + soil mixture. Implications: Using local and inexpensive substrates will impact production costs for marigold farmers. Currently, a variety of commercial mixes and substrates of foreign origin are available and used for the production of container-grown plants. Conclusions: The best results were obtained with organic substrates, specifically with ocote pine needles and leaf mold. The mixture with sawdust did not show good results in the tested variables, possibly due to this material’s high carbon/nitrogen ratio. The lowest results were obtained with the sand + soil treatment. Keywords: Asteraceae, yield, sawdust, needle, Tagetes erecta

Identification of the sweet orange (Citrus sinensis) bHLH gene family and the role of CsbHLH55 and CsbHLH87 in regulating salt stress.

Salt stress is one of the primary environmental stresses limiting plant growth and production and adversely affecting the growth, development, yield, and fruit quality of Citrus sinensis. bHLH (basic helix-loop-helix) genes are involved in many bioregulatory processes in plants, including growth and development, phytohormone signaling, defense responses, and biosynthesis of specific metabolites. In this study, by bioinformatics methods, 120 CsbHLHgenes were identified, and phylogenetic analysis classified them into 18 subfamilies that were unevenly distributed on nine chromosomes. The cis-acting elements of the CsbHLH genes were mainly hormone-related cis-acting elements. Seventeen CsbHLH genes exhibited significant differences in expression under salt stress. Six CsbHLH genes with significant differences in expression were randomly selected for quantitative real-time polymerase chain reaction (qRT-PCR) validation. The qRT-PCR results showed a strong correlation with the transcriptome data. Phytohormones such as jasmonic acid (JA) are essential for biotic and abiotic stress responses in plants, and CsbHLH55 and CsbHLH87 are considered candidate target genes for sweet orange MYC2 transcription factors involved in the JA signaling pathway. These genes are the main downstream effectors in the JA signaling pathway and can be activated to participate in the JA signaling pathway. Activation of the JA signaling pathway inhibits the production of reactive oxygen species and improves the salt tolerance of sweet orange plants. The CsbHLH55 and CsbHLH87 genes could be candidate genes for breeding new transgenic salt-resistant varieties of sweet orange.

Entrepreneurship Development in Islamic Boarding School Through Tabulampot Cultivation

Indonesia is still trying to reduce poverty. One alternative to reducing poverty is through entrepreneurship. Therefore, entrepreneurial education is considered necessary to be introduced early. Tabulampot (Tanaman Buah Dalam Pot) is a technique for cultivating plants in containers, which can be in the form of pots or barrels, it can be an alternative for farming on limited land. This is considered to be an entrepreneurial potential that can encourage the economy of village communities. Entrepreneurship development is carried out at the Al-Munawar Islamic Boarding School, Garut, West Java by involving the pesantren administrators, students, and the community around the Islamic boarding school. The method used in entrepreneurship development is direct assistance by tabulampot practitioners and the provision of entrepreneurship. Based on the geographical characteristics of Islamic boarding schools, the plants that will be cultivated are mango, orange, and guava plants. Tabulampot cultivation has two main results, first the tabulampot harvest, which can be consumed by students and residents around the Islamic boarding school. The main reson is that the results of tabulampot cultivation can be reproduced and traded, which can then be sold and generate profits to advance the Islamic boarding school’s economy. This can encourage Islamic boarding school independence in the economic aspect. Keywords: entrepreneurship, Islamic boarding school, Tabulampot

Synthesis and Evaluation of Copper Oleate Nanoparticles Against Citrus Anthracnose Caused by Colletotrichum gloeosporioides: In Situ Experiments, In Vitro Bioassays, and Field Trials

AbstractAnthracnose in citrus is a severe disease caused by Colletotrichum species. Synthetic fungicides have been used to combat this citrus disease; however, they may have adverse health effects on humans and cause harmful environmental impacts. During a search for environmentally friendly fungicides, we successfully prepared organic copper (copper (II) oleate) nanoparticles by using natural chitosan polymer as a coating agent and stabilizer and by combining an exchange reaction and in situ coating method. Organic copper nanoparticles coated with chitosan polymer (Cu‐oleate@CS NPs) with Cu contents ranged from 5.0 to 6.0 % by weight. The nanoparticles have an average particle size ranging from 50 nm to 60 nm (TEM), covered by a layer of polymer with a thickness of about 10 to 12 nm. The analytical results of zeta potential and dynamic solution size showed that the nanoparticles are uniformly dispersed (90–120 nm by DLS), with high stability (zeta potential=−61.7 mV) and low cytoxicity to Vero healthy cell line. Cu‐oleate@CS NPs significantly inhibited the mycelial growth of C. gloeosporioides in vitro at 500 and 1000 μg/mL. In field trials, the best antifungal efficacy of Cu‐oleate@CS NPs against citrus anthracnose on orange plants was found at a spray concentration of 0.33 % with a disease control efficacy of 54.18 % at 14 days after the second spraying. Our study results demonstrated a novel preparation of Cu‐oleate@CS NPs and suggested that it could be used as a promising nanoformulation to control citrus anthracnose in vitro and in vivo.

Induction of Somatic Embryogenesis of Pontianak Siamese Orange Cotyledon Cultures on Murashige Skoog Media with the Addition of 2,4-D and Kinetin

Conventional citrus propagation has weaknesses, one of which is susceptible to CVPD(Citrus Vein Phloem Degeneration) and other diseases which are the main cause of the decline in population and production of pontianak siam orange plants in West Kalimantan. One alternative to in vitro propagation of citrus seedlings is the induction of somatic embryogenesis. The purpose of the study was to obtain the best combination of 2,4-D and kinetin concentrations for callus induction and somatic embryo induction from Pontianak siam orange cotyledon explants, observing the developmental phase (stage) of embryos formed. The implementation of the study used a factorial completely randomized design (CRD) consisting of 2 factors. The first factor is the concentration of 2,4-D consisting of 4 concentration levels, namely 0; 0.5; 1; 1.5; 2 mg/L. The second factor is kinetin concentration consisting of 4 concentration levels, namely 0; 0.5; 1; 1.5; 2 mg/L.The observation parameters include the time of callus emergence (hst), the percentage of explants forming callus (%), the texture and color of the callus, observing the stage of the embryo found. The results showed that 72% of treatments were able to induce callus from pontianak siam orange cotyledons with an average callus appearance at 7 hst. The callus formed is compact and crumbly with varied callus colors, namely white, yellowish, greenish and brownish. The best treatment that produces embryogenic callus is the combination of D0.5K0.5; D1K1; D0.5K1.5; D1.5K1.5 and D2K2 with the characteristics of crumbly callus and yellowish and brownish colors. The results of microscopic observations found that the somatic embryo phase formed was the pro-embryo phase.

Citrus psorosis virus 24K protein inhibits the processing of miRNA precursors by interacting with components of the biogenesis machinery.

Sweet orange (Citrus sinensis) is one of the most important fruit crops worldwide. Virus infections in this crop can interfere with cellular processes, causing dramatic economic losses. By performing RT-qPCR analyses, we demonstrated that citrus psorosis virus (CPsV)-infected orange plants exhibited higher levels of unprocessed microRNA (miRNA) precursors than healthy plants. This result correlated with the reported reduction of mature miRNAs species. The protein 24K, the CPsV suppressor of RNA silencing (VSR), interacts with miRNA precursors in vivo. Thus, this protein becomes a candidate responsible for the increased accumulation of unprocessed miRNAs. We analyzed 24K RNA-binding and protein-protein interaction domains and described patterns of its subcellular localization. We also showed that 24K colocalizes within nuclear D-bodies with the miRNA biogenesis proteins DICER-LIKE 1 (DCL1), HYPONASTIC LEAVES 1 (HYL1), and SERRATE (SE). According to the results of bimolecular fluorescence complementation and co-immunoprecipitation assays, the 24K protein interacts with HYL1 and SE. Thus, 24K may inhibit miRNA processing in CPsV-infected citrus plants by direct interaction with the miRNA processing complex. This work contributes to the understanding of how a virus can alter the regulatory mechanisms of the host, particularly miRNA biogenesis and function.IMPORTANCESweet oranges can suffer from disease symptoms induced by virus infections, thus resulting in drastic economic losses. In sweet orange plants, CPsV alters the accumulation of some precursors from the regulatory molecules called miRNAs. This alteration leads to a decreased level of mature miRNA species. This misregulation may be due to a direct association of one of the viral proteins (24K) with miRNA precursors. On the other hand, 24K may act with components of the cell miRNA processing machinery through a series of predicted RNA-binding and protein-protein interaction domains.

Identification and Potential of Secondary Metabolism of Weeds as Bio Herbicides in Environmentally Friendly Citrus Cultivation

Production of oranges in Indonesia increased from 1.78 million tons to 2.16 million tons in 2014. In 2016, Indonesia imported 2,212 tons of oranges. Weed plants caused a decline in orange production, leading to a decrease in harvest yields by 61%. The research aimed to identify weed species and the potential secondary metabolism of dominant weeds on orange plants. The research method utilized weed vegetation analysis, focusing on the Summed Dominance Ratio (SDR). The treatments with kirinyuh extract (P0) were as follows: (Control); P1: 20%; P2: 40%; P3: 60%; P4: 80%. Observation parameters included phytotoxicity, wet weight, and dry weight. The research results revealed 10 families, 25 species, and 400 weed individuals. Weeds with the highest SDR value were of the Oldenlandia corymbose type, with a Summed Dominance Ratio (SDR) of 7.28%, and the second-highest SDR value was Euphorbia hirta weed with 7.22%. The lowest was the Richardia brasiliensis weed with an SDR value of 0.633%. Phytotoxicity on kirinyuh leaf plants was highest in P4 with a concentration of 80g/l at 47.33. Wet weight and dry weight influenced P4 concentration, with an 80g/l concentration most inhibiting the growth of kirinyuh leaves. Laboratory analysis of flavonoid, total phenolic, and tannin content showed that Euphorbia hirta weed had higher levels compared to Oldenlandia corymbose weed.

Abstract. Nurzaman M, Setiawati T, Hasan R, Qotrunnada NK, Kusmoro J, Permadi N, Julaeha E. 2024. The phenetic relationship of citrus plants based on the morphological and anatomical characteristics. Biodiversitas 25: 1201-1213. Indonesia stands as a global biodiversity hub, boasting an exceptional richness that earns it the distinction of being a mega-biodiversity country. Among its diverse ecosystems, the Rutaceae family holds significance, encompassing numerous genera, notably the Citrus genus, which showcases a splendid array of citrus plants. This research aimed to determine phenetic relationships based on the morphological and anatomical characters of seven citrus plants (Citrus reticulata var. Chokun, C. reticulata var. Fremont, C. reticulata var. Santang, C. reticulata var. Dekopon, C. aurantium var. variegata, C. aurantium, and C. limon) in Parongpong District, West Bandung Regency, West Java. The method used in this research was explorative with purposive sampling. This study collected three samples for respective citrus plants for character observations of leaf morphology, anatomy, and fruit morphology. Morphology and anatomy observations were conducted in the Department of Biology, Padjadjaran University laboratory. The description of morphological and anatomical data obtained from each orange plant was then analyzed using NTSYS PC version 2.11a software to obtain similarity values using the dendrogram analysis method. Phenetic analysis of seven orange plants produced a dendrogram divided into 2 main branches, branch I and branch II, with a similarity coefficient of 0.3846. Branch I consists of Chokun orange (Citrus reticulata var. Chokun), Fremont orange (C. reticulata cv. Fremont), Santang orange (C. reticulata cv. Santang), and variegated orange (C. sinensis cv. variegata) and branch II consists of dekopon orange (C. reticulata var. Dekopon), Sunkist orange (C. aurantium), and lemon (C. limon).

Silica and Selenium Nanoparticles Attract or Repel Scale Insects by Altering Physicochemical Leaf Traits.

Although nanoparticles have gained attention as efficient alternatives to conventional agricultural chemicals, there is limited knowledge regarding their effects on herbivorous insect behavior and plant physicochemistry. Here, we investigated the effects of foliar applications of nano-silica (SiO2NPs) and nano-selenium (SeNPs), and bulk-size silica (SiO2) on the choice behavior of the arrowhead scale insect on mandarin orange plants. One leaf of a bifoliate pair was treated with one of the three chemicals, while the other was treated with water (control). The respective SiO2, SeO2, calcium (Ca), and carbon (C) content levels in the leaf epidermis and mesophyll were quantified using SEM-EDX (or SEM-EDS); leaf toughness and the arrowhead scale density and body size were measured. First-instar nymphs preferred silica-treated leaves and avoided SeNP-treated leaves. SiO2 content did not differ between control and SiO2NP-treated leaves, but was higher in bulk-size SiO2-treated leaves. The SiO2 level in the control leaves was higher in the SiO2NP treatment compared with that in the control leaves in the bulk-size SiO2 treatment. Silica-treated leaves increased in toughness, but SeNP-treated leaves did not; leaf toughness increased with mesophyllic SiO2 content. The insect density per leaf increased with leaf toughness, SiO2 content and, in the SiO2NP treatment, with epidermal C content. There was no correlation between SeO2 content and insect density. This study highlights the potential uses of SeNPs as an insect deterrent and of silica for enhancing leaf toughness and attracting scale insects.

Brevipalpus yothersiBaker (Tenuipalpidae) development in sweet orange plants is influenced by previous mite infestation and the presence of shelters.

Citrus leprosis is the most important viral disease affecting citrus. The disease is caused predominantly by CiLV-C and is transmitted by Brevipalpus yothersi Baker mites. This study brings some insight into the colonization of B. yothersi in citrus [(Citrus × sinensis (L.) Osbeck (Rutaceae)] previously infested by viruliferous or non-viruliferous B. yothersi. It also assesses the putative role of shelters on the behavior of B. yothersi. Expression of PR1 and PR4 genes, markers of plant defense mechanisms, were evaluated by RT-qPCR to correlate the role of the plant hormonal changes during the tri-trophic virus-mite-plant interplay. A previous infestation with either non-viruliferous and viruliferous mites positively influenced oviposition and the number of adult individuals in the resulting populations. Mite populations were higher on branches that had received a previous mite infestation than branches that did not. There was an increase in the expression of PR4, a marker gene in the jasmonic acid (JA) pathway, in the treatment with non-viruliferous mites, indicating a response from the plant to their feeding. Conversely, an induced expression of PR1, a marker gene in the salicylic acid (SA) pathway, was observed mainly in the treatment with viruliferous mites, which suggests the activation of a plant response against the pathogen. The earlier mite infestation, as well as the presence of leprosis lesions and a gypsum mixture as artificial shelters, all fostered the growth of the B. yothersi populations after the second infestation, regardless of the presence or absence of CiLV-C. Furthermore, it is suggested that B. yothersi feeding actually induces the JA pathway in plants. At the same time, the CiLV-C represses the JA pathway and induces the SA pathway, which benefits the mite vector.

Negotiating soil water deficit in mycorrhizal trifoliate orange plants: A gibberellin pathway

Gibberellins (GAs), an important endogenous hormone, serve a crucial regulatory role in plants’ resistance to environmental stress, whereas it is unclear whether and how arbuscular mycorrhizal fungi (AMF) regulate the profile of GAs in plants exposed to soil water deficit (SWD). This study aimed to analyze how Rhizoglomus intraradices inoculation affected plant growth performance, antioxidant enzyme activities, and the composition, synthesis, metabolism, and signaling pathways of GAs in the roots of trifoliate orange (Poncirus trifoliata) under a 10-week SWD. Although the SWD decreased both root AMF colonization and soil hyphal length, mycorrhizal plants nevertheless outperformed non-mycorrhizal plants in terms of growth performance, as well as peroxidase (70.0%) and catalase (149.2%) activities, indicating greater drought tolerance. A total of nine GAs compositions were detected in the roots, with bioactive GA4 exclusively found in AMF roots. AMF colonization significantly reduced bioactive GA3 levels by 37.9%, while it increased inactive GA8, GA9, and GA15 levels under SWD by 522.2%, 100.0%, and 2500.0%. Inoculation with AMF also up-regulated the expression of PtCPS, PtPKS, and PtKO in GA synthesis pathways of roots and the expression of PtGA20ox, PtGA3ox, and PtGA2ox in GA metabolisms under SWD. In addition, the expression of DELLA genes PtGaipb and PtGai associated with GA signaling pathways was further up-regulated under SWD by AMF inoculation. It is concluded that AMF regulated the composition, synthesis, and deactivation of GAs in roots to promote plant growth, along with an increase in PtGaipb and PtGai expression to possibly initiate mycorrhizal signaling pathways in response to SWD.

Detection of mealybug infestation on the Khasi Mandarin orange plant using electronic nose

Mealybugs pose a serious threat to fruit crops leading to premature leaf and fruit drops which severely affects the yield as well as the quality. Primarily pest detection is done with the help of human/animal scouting, which is cumbersome and prone to error. This paper studies the feasibility of using an electronic nose (E-Nose) for detecting mealybug infestation in Khasi Mandarin orange plants. Plants normally release volatile organic compounds (VOCs) which can act as biomarkers for specific stresses affecting the plant. These VOCs can be analyzed to diagnose the plant. VOCs emanating from leaf samples of both infested and healthy plants were analyzed using a custom-made E-Nose system containing an array of commercially available gas sensors. Dimensionality reduction techniques using principle component analysis, and linear discriminant analysis and optimized classification algorithms like support vector machine and random forest were employed to check for the discriminating capability of the E-Nose system. The technique successfully classified samples belonging to infested and healthy categories in both the classifiers with accuracies of 95.66% and 96.70%.

Peracetic acid residues in orange juice can lead to a 5-vinylguaiacol-induced clove-like off-flavor via Baeyer-Villiger oxidation of hesperidin

A balanced flavor is a major quality attribute of orange juice. Formation of 4-vinylguaiacol during storage can lead to an undesirable clove-like off-flavor. However, clove-like off-flavors were occasionally reported despite low 4-vinylguaiacol concentrations, suggesting an alternative molecular background. Application of gas chromatography–olfactometry and aroma extract dilution analysis to an orange juice with a pronounced clove-like off-flavor resulted in the identification of 5-vinylguaiacol. The compound showed the same odor as 4-vinylguaiacol, but was previously unknown in orange juice. In five of six commercial orange juices with clove-like off-flavors, 5-vinylguaiacol was even more odor-active than 4-vinylguaiacol. Spiking and model studies suggested that 5-vinylguaiacol is formed during pasteurization from the natural orange juice component hesperidin and residual peracetic acid used as cleaning agent by a Baeyer-Villiger oxidation. An activity-guided screening approach confirmed the role of hesperidin as 5-vinylguaiacol precursor. In conclusion, peracetic acid should no longer be used in orange juice processing plants.

Effect of Different NPK Levels and Chlorophyll Content on Growth and Development of Sweet Orange (Citrus sinesis Osbeck)

The current study, which was conducted at the Agricultural Research Farm of Rama University in Mandhana, Kanpur, India, was titled Effect of varying amounts of Nitrogen (N), Phosphorus (P2O5), and Potassium (K2O) on growth and development of Sweet Orange (Citrus sinesis Osbeck) plants. In terms of maximum plant height (83.57 cm), maximum number of leaves (421.04), maximum number of branches (26.36), maximum stem diameter (3.04 cm), maximum spread of canopy (42.36 cm), maximum length of inter-nodes (9.68 cm), and maximum chlorophyll content (4.58 mg/g), the results showed that treatment T2 (850 g / plant Nitrogen, 600 g / plant Phosphorus, and 850 g / plant Potash) achieved the best results followed by treatment T9 (800 g / plant Nitrogen, 400 g / plant Phosphorus and500 g / plant Potash) and the minimum was recorded in T4(700g / plant Nitrogen, 400g / plant Phosphorus and 400g / plant Potash).

Synephrine and Its Derivative Compound A: Common and Specific Biological Effects.

This review is focused on synephrine, the principal phytochemical found in bitter orange and other medicinal plants and widely used as a dietary supplement for weight loss/body fat reduction. We examine different aspects of synephrine biology, delving into its established and potential molecular targets, as well as its mechanisms of action. We present an overview of the origin, chemical composition, receptors, and pharmacological properties of synephrine, including its anti-inflammatory and anti-cancer activity in various in vitro and animal models. Additionally, we conduct a comparative analysis of the molecular targets and effects of synephrine with those of its metabolite, selective glucocorticoid receptor agonist (SEGRA) Compound A (CpdA), which shares a similar chemical structure with synephrine. SEGRAs, including CpdA, have been extensively studied as glucocorticoid receptor activators that have a better benefit/risk profile than glucocorticoids due to their reduced adverse effects. We discuss the potential of synephrine usage as a template for the synthesis of new generation of non-steroidal SEGRAs. The review also provides insights into the safe pharmacological profile of synephrine.
