4. Biomass Accumulation, Photosynthetic Pigments, Osmotic Adjustments and Antioxidant Activities of Leymus chinensis in Response to BA, BR, and GA
RESUMO: Estresses abióticos e baixo acúmulo de biomassa são as principais restrições para se atingir o potencial de rendimento de Leymus chinensis. Foi conduzido um experimento para melhorar a biomassa e a correlação de atributos de acúmulo de biomassa com pigmentos fotossintéticos, substâncias osmóticas e antioxidantes sob aplicação foliar de d

5. Allelopathic Potential of Ethanolic Extract and Phytochemical Analysis of Paspalum maritimum Trind
RESUMO: Alelopatia é definida como a capacidade que determinadas plantas e microrganismos têm de interferir no metabolismo de outras espécies, por meio de substâncias liberadas no ambiente, podendo ser uma alternativa de combate às plantas daninhas e doenças. Nesse contexto, este estudo teve por objetivos avaliar o potencial alelopático e identificar

6. Control potential of Meloidogyne javanica and Ditylenchus spp. using fluorescent Pseudomonas and Bacillus spp.
ABSTRACT Plant Growth Promoting Rhizobacteria (PGPR) have different mechanisms of action in the development of plants, such as growth promotion, production of phytohormones and antibiotic substances and changes in root exudates. These help to control plant diseases. In order to evaluate the potential of microorganisms in the control of Meloidogyne javanica a

7. Utilization of dynamic light scattering to evaluate Pterodon emarginatus oleoresin-based nanoemulsion formation by non-heating and solvent-free method
Abstract Pterodon emarginatus Vogel, Fabaceae, is a great source of bioactive compounds. The most known and studied herbal derivative from this species is an ambar-colored oleoresin that contains vouacapane diterpenes and volatile terpenoids, such as β-caryophyllene. Some recent papers aimed to generate nanoemulsions using this oleoresin for biological appl

8. Effects of Arbuscular Mycorrhiza on Osmotic Adjustment and Photosynthetic Physiology of Maize Seedlings in Black Soils Region of Northeast China
ABSTRACT To investigate the effect of arbuscular mycorrhiza fungi on maize growth, osmoregulation substances and photosynthetic physiology, a popular maize variety ZD 958 was measured under potted condition. Arbuscular mycorrhiza (AM) symbiosis promoted plant growth, and enhanced plant height, leaf length, mean leaf width and dry weight. Higher soluble sugar

9. Plant biostimulants: physiological responses induced by protein hydrolyzed-based products and humic substances in plant metabolism
ABSTRACT In recent years, the use of biostimulants in sustainable agriculture has been growing. Biostimulants can be obtained from different organic materials and include humic substances (HS), complex organic materials, beneficial chemical elements, peptides and amino acids, inorganic salts, seaweed extracts, chitin and chitosan derivatives, antitranspirant

10. Plant proton pumps as markers of biostimulant action
ABSTRACT A standard protocol to evaluate the effects of biostimulants on plant physiology is still lacking. The proton pumps present in the vacuolar and plasma membranes are the primary agents responsible for the regulation of the electrochemical gradient that energizes the nutrient uptake system and acid growth mechanism of plant cells. In this study, two o

12. Use of non-hyperaccumulator plant species for the phytoextraction of heavy metals using chelating agents
Soil contamination by heavy metals is a challenge faced by many countries, and engineering technologies to solve this problem are expensive and can cause negative impacts on the environment. One way to minimise the levels of heavy metals in the soil is to use plants that can absorb and accumulate heavy metals into harvestable parts, a process called phytoext
