Induced Resistance against Pseudomonas syringae pv. lachrymans in Cucumber by Spraying Cell-Free Microalgae Supernatant.

Chlorella is a genus of aquatic photosynthetic microalgae used in the production of dietary supplements, cosmetics, and biofuels, and also recently utilized as biological control agents or biofertilizers in agricultural supplements. Chlorella supernatant elicits induced resistance in Arabidopsis thaliana but its effects on crop plants remain largely unknown. This study tested whether application of Chlorella supernatant elicited induced resistance in cucumber (Cucumis sativus L.

Control of Cucumber Powdery Mildew Using Resistant Cultivars and Organic Agricultural Materials.

This study evaluated the efficacy of various inorganic materials, biological control agents, organic agricultural materials (OAMs), and essential oils for controlling cucumber powdery mildew (CPM) under greenhouse conditions. Treatments included silicate, bicarbonate, copper sulfate, sulfur-based compounds, KB-401, M27, Bordeaux mixtures, chitosan combined with oxidated copper salt, chitooligosaccharides, and essential oils such as castor and rapeseed oil with lecithin. Results demonstrated that Bordeaux mixtures, particularly Bordeaux Mixture I, and sulfur-based compounds provided the most reliable CPM control among inorganic materials.

Anti-obesity and immunomodulatory effects of Allium hookeri leaves cultivated with artificial light of different intensities on immune-depressed obese mice.

This study was conducted to evaluate the effects of Allium hookeri (AH) leaves cultivated with different light-emitting diode (LED) intensities (L: low, 100 μmol/m/s; M: medium, 150 μmol/m/s; H: high, 200 μmol/m/s). Alliin concentration increased as light intensity increased in AH and showed the highest level at LED-H condition. The anti-obesity and immunomodulatory properties of AH were evaluated in a cyclophosphamide (CPA)-induced immunosuppressed obese animal model.

Nutrient release pattern and mitigation of NO emissions under the application of activated poultry manure compost biochar with organic resources.

Biochar was generally used to reduce the macronutrient releases and to mitigate NO gas emissions in cropland. This experiment evaluated the trend of major plant nutrient releases using the modified Hyperbola model and the greenhouse gas emissions by incorporating different poultry manure compost biochar with organic resources. The treatments consisted of the control as the organic fertilizer materials, the incorporated poultry manure compost biochar with organic fertilizer materials (PMCBF), and the incorporated plasma-activated poultry manure compost biochar with organic fertilizer materials (PAMBF) under redox conditions.

The Immune-Stimulating and Anti-Diabetic Effects of Leaves Grown in a Plant Factory with Artificial Lights in Immunosuppressed Obese C57BL/6 Mice.

We investigated the immune-stimulating and anti-diabetic effects of leaves grown in a plant factory with artificial lights. The immunomodulatory effects of leaves' ethanol extracts were evaluated with immune-related hematological factors in blood, the proliferation of splenocytes, NK cell activity, IgG and cytokine levels, and their mechanisms in immunosuppressed obese mice. Anti-diabetic effects were determined by the inhibitory activity against α-amylase and α-glucosidase in vitro and fasting blood glucose levels and biochemical factors in the serum of immunosuppressed obese mice.

Evaluation of the Impact of Activated Biochar-Manure Compost Pellet Fertilizer on Volatile Organic Compound Emissions and Heavy Metal Saturation.

For this experiment, pelletized activated biochar made of rice hullsor palm bark with swine manure compost was prepared to demonstrate the significant benefits of applying activated biochar-manure compost pellet fertilizer (ABMCP) inmitigating volatile organic compounds (VOCs), odor emission, and heavy metal saturation. Morphology and surface area analysis indicated that the activated rice hull biochar-manure compost pellet (ARP) had a significantly lower surface area, porous volume, and Fe content the activated palm biochar-manure compost pellet (APP). However, the ARP presented great potential to mitigate VOCs and odorant emissions.

Potential of Algae-Bacteria Synergistic Effects on Vegetable Production.

Modern agriculture has become heavily dependent on chemical fertilizers, which have caused environmental pollution and the loss of soil fertility and sustainability. Microalgae and plant growth-promoting bacteria (PGPB) have been identified as alternatives to chemical fertilizers for improving soil fertility. This is because of their biofertilizing properties, through the production of bioactive compounds (e.

Plant anti-aging: Delayed flower and leaf senescence in treated with cell-free cultivation medium.

Plant tissues naturally senesce over time. Attempts to improve plant robustness and increase longevity have involved genetic modification, application of synthetic chemicals, and use of beneficial microbes. Recently, culture supernatant from a microalga was found to prime innate immunity against in .

Effect of Biostimulator on Improving Growth and Qualities of Chinese Chives and Spinach in Organic Farm.

This study was conducted to investigate the efficacy of freshwater alga, on the improvement of growth and qualities in organic spinach and Chinese chives farm. The average height of Chinese chives treated with the chlorella was 3.7 cm smaller than that of the untreated.

Enhancement of Seed Dehiscence by Seed Treatment with GG01 and GG04 in Ginseng ().

Seed dehiscence of ginseng ( C. A. Mayer) is affected by moisture, temperature, storage conditions and microbes.
