It impacts various growth stages, including seed germination, vegetative growth, reproductive development and crop maturity. Among these stages, seed germination is particularly sensitive. In this study, we aimed to assess the effect of water deficit by manipulating the water potential of the germination medium [0, − 1, − 1.5 and − 2 MPa (Megapascal)]. Our results revealed that a decrease in the osmotic potential influenced all seedling parameters. Specifically, we observed variations in the activity of amylase, an enzyme involved in starch breakdown during germination. The timing of amylase activity depended on both the germination duration and the severity of water deficit. After 24 h, amylase activity increased due to reduced water potential, but it reached its peak after 48 h and subsequently decreased significantly under water stress. This enzymatic activity led to the accumulation of simple sugars in germinating seeds. Interestingly, our study also revealed intraspecific variability in the response to water stress. Specifically, seeds from the Chen’s and Simeto genotypes exhibited higher accumulation of soluble sugars compared to other genotypes, indicating their greater tolerance to water deficit. Considering this, integrating these tolerant genotypes into genetic improvement programs could enhance durum wheat resilience to water scarcity. Understanding the impact of water deficit on seed germination and seedling development is crucial for developing strategies to mitigate its effects and improve crop productivity in water-limited environments.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 4","pages":"676 - 683"},"PeriodicalIF":1.4,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141364034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study highlighted the impact of biochar and AMF on the growth of turmeric, nutrients and physiological properties under drought stress. Turmeric plants were grown under water stress in a net house. Four treatments used for the experiments included control (only soil), biochar, AMF, and combined treatment with biochar and AMF. For the pot experiments, 1% biochar was mixed with soil. AMF contained 100 spores/g and 1200 IP/g. Maximum improvement in rhizome biomass, rhizome number and availability of plant nutrients was observed after the co-application of biochar and AMF. Significant improvement in microbial biomass and AMF spore numbers was also observed in the soil exposed to biochar + AMF. Applying biochar and AMF in combination under water stress significantly enhanced fluorescein diacetate dehydrogenase and alkaline phosphatase activity in the soil compared to control. Results suggested that co-supplementation of biochar and AMF can promote soil nutrients along with turmeric's growth parameters and physiological properties in water stress.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 4","pages":"802 - 813"},"PeriodicalIF":1.4,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141363376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though previous studies report their effects on lungs, information on the molecular mechanism of lung injury following exposure to mixture of fipronil and imidacloprid is limited. Hence, in this study the molecular mechanism behind fipronil and imidacloprid induced lung toxicity was explored. In the animal experimental work, Swiss albino mice aged (6–8 weeks) were orally administered with high (0.91 mg/kg i.e., 1/100th of LD₅₀) and low (0.60 mg/kg i.e., 1/150th of LD₅₀) doses of fipronil and imidacloprid (high-1.31 mg/kg and low- 0.87 mg/kg) individually and in combination for 90 consecutive days to identify the association of lung damage with mitochondrial ROS (mtROS) formation. Blood and bronchoalveolar lavage fluid (BALF) were collected for total leukocyte count (TLC) and differential leukocyte count (DLC) analysis. Lung samples were processed for histopathological examination and mtROS measurement. TLC, DLC scores and histopathological examination suggested lung inflammation. There was statistically significant increase (<i>P</i> &lt; 0.05) in mtROS in lungs treated with imidacloprid and in combination with fipronil at low doses compared to the control group suggesting the induction of oxidative stress.

To impede the harmful effects of ROS, plant cells follow a multileveled complex network system of antioxidants, thus maintaining the cellular redox homeostasis. Report suggests plants having better antioxidative system show better performance under oxidative stress. Low molecular weight nucleoredoxin (NRX) is a nuclear thioredoxin (TRX) system with oxidoreductase capacity which can protect the cellular components like DNA, RNA or protein by protecting antioxidative enzymes like catalases. In response to the adverse environmental conditions, plant cells generate more ROS as a result of signal-led cellular defense mechanism. NRX plays a significant role in regulating the redox balance of the cell. Furthermore, for stress breeding during the process of developing stress-resistant varieties favorable alleles of NRX can be introgressed into elite breeding lines of different crops. This review describes the causes of oxidative stress, ROS production, major classes of ROS, role of ROS on plant growth and development, functional details of plant NRX and recent updates on plant NRX in different crops, especially in alleviating stress-incurred damages.

In particular, little attention has been paid to the effects of combining green manure with PGPF on soil enzyme activities, fungal biomass and population, and plant growth promotion. Therefore, we conducted to clarify the effects of the combined application of green manure and the <i>Trichoderma</i> spp. strain RW309 having phosphorus- and carbon-related enzyme activities, plant growth-promoting potential, and also influence on soil fungal community. Two green manure treatments [<i>Vicia</i> <i>villosa</i> (hairy vetch) and <i>Brassica</i> <i>juncea</i> (L.)] with and without RW309, only RW309, and control (only soil), were applied. Soil samples were collected after the co-application of treatments and after plant harvesting soil. This is the first finding that plant growth was significantly higher with green manure combined with RW309 inoculation than with green manure alone. The enzyme activities and fungal biomass were also markedly higher in the co-application treatments than in the other treatments. It is likely that the co-incorporation of green manure and RW309 decomposes organic matter faster and provides an energy source to soil microbes. Moreover, new finding was to enhance specific fungal genera (<i>Penicillium</i> spp.), which may be responsible for nutrient mineralisation and plant growth promotion.

The paper also considers the indigenous weather prediction approaches used in the area. A participatory rural appraisal is complemented by a qualitative and quantitative approach. This study used semi-structured interviews, questionnaires and focus group discussions for data collection. A survey of 200 randomly selected indigenous farmers was sampled. The finding revealed that local farmers depend on the use of indigenous knowledge practices to improve household food security. The majority of farmers apply manure in their farms using livestock dumps. Also, it shows that 87.8% of households used sun-drying processes for food preservation and used local mortars to pound and grind foodstuffs such as peanuts and maize. Practices such as crop rotations, mixed cropping and intercropping were employed to improve soil fertility and climate change and reduce insect pest outbursts on crops, hence, improving crop production. Indigenous knowledge of rainfall prediction is helpful in preparation for the planting season. The study recommended that agriculture policies must acknowledge indigenous knowledge practices in development programmes and specific policy interventions to promote the indigenous knowledge systems must focus on enhancing socio-economic factors assisting farmers in improving post-harvest storage facilities.

The technique reduces berry number to improve fruit growth, but it is costly and in some cases impractical in the entire extension of an orchard. The right moment for execution and the intensity are complex issues that involve specific knowledge about the conditions of the vineyard. Therefore, phenological information that can help planning and decision-making about thinning is relevant and can improve the cost-effectiveness of the technique in viticulture. An electronic nose system was developed to collect and analyze compound volatile variations during the growing season, more specifically during the period of bud growth and ripening in three grape cultivars (BRS Vitória, Niagara Rosada, Bordô). The data were collected from October 2021 to February 2022. The research hypothesis is that the electronic nose can identify the general stage of plant development. To verify the hypothesis, a classification analysis was performed for each cultivar. The result showed that all models presented balanced accuracy above 85% for the cultivar BRS Vitória, above 92% for Niagara, and above 93% for Bordô, with better performance for models based on <i>K-nearest neighbors </i> (KNN), and <i>random forest</i>, than those based on <i>extreme learning machine</i> and <i>support vector machine</i>.
