    Yujie Yang1, Chengshi Huang2, Zuguo Ge3, Bengeng Zhou4, Guangju Su4, Chunling Liu4, Yongjun Fei1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.1, pp. 129-148, 2022, DOI:10.32604/phyton.2022.016704

    Abstract Drought stress negatively impacts growth and physiological processes in plants. The foliar application of glycine betaine (GB) is an effective and low-cost approach to improve the drought tolerance of trees. This study examined the effect of exogenously applied GB on the cell membrane permeability, osmotic adjustment, and antioxidant enzyme activities of Phoebe hunanensis Hand.-Mazz under drought stress. Two levels (0 and 800 mL) of water irrigation were tested under different applied GB concentrations (0, 50, 100, and 200 mM). Drought stress decreased the relative water content by 58.5% while increased the electric conductivity, malondialdehyde, proline, soluble proteins,… More >

    Seerat Saleem1, Naveed Ul Mushtaq1, Wasifa Hafiz Shah1, Aadil Rasool1, Khalid Rehman Hakeem2,*, Reiaz Ul Rehman1,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.5, pp. 1363-1385, 2021, DOI:10.32604/phyton.2021.014826

    Abstract Abiotic stresses such as drought, heat, cold, nutrient deficiency, excess salt and hazardous metals can hamper plantgrowth and development. Intensive agriculture of only a few major staple food crops that are sensitive and intolerant to environmental stresses has led to an agrarian crisis. On the other hand, nutritionally rich, gluten free and stress tolerant plants like millets are neglected and underutilized. Millets sustain about one-third of the world’s population and show exceptional tolerance to various abiotic and biotic stresses. Millets are C4 plants that are adapted to marginal and dry lands of arid and semi-arid… More >

    Journal of Renewable Materials, Vol.8, No.11, pp. 1519-1529, 2020, DOI:10.32604/jrm.2020.011453

    Abstract Drought is one of the major abiotic stresses that affect plant growth and reduce agricultural productivity. Use of algal extract as a biostimulant is gaining increased attention from researchers. This study aimed to investigate the potential of Ulva prolifera extract (UE) as a biostimulant when enzymatically extracted under conditions of water deficit. UE treatments (0.02%, 0.06%, and 0.1%) significantly improved the shoot length, root length, and dry weight of roots after 120 h of drought stress relative to that in treatment with the negative control. An increase in catalase (CAT) and peroxidase (POD) activity was also More >

    A Numerical Investigation into the Influence of Electrode-Related Parameters on Electroosmotic Mixing and Related Mechanisms

    Chunsheng Wang*, Dongxing Shang

    FDMP-Fluid Dynamics & Materials Processing, Vol.16, No.3, pp. 465-473, 2020, DOI:10.32604/fdmp.2020.08828

    Abstract Electroosmosis is an effective method for liquid mixing. It is associated with the motion of a liquid in a microchannel induced by an applied electric field. In this manuscript, a numerical model is elaborated and implemented for the case of a straight channel with a single electrode pair. In particular, the Navier-Stokes equation combined with the Convection-diffusion and Helmholtz-Smoluchowski equation are used to simulate the resulting flow field. The influence of various electrode parameters on the mixing efficiency and the related mechanisms are investigated. The numerical results show that a pair of eddies are produced More >

    Maroua Ben Abdelkader1,2,*, Nedra Azizi1, Ayda Baffoun3, Yves Chevalier2, Mustapha Majdoub1

    Journal of Renewable Materials, Vol.7, No.12, pp. 1347-1362, 2019, DOI:10.32604/jrm.2019.07926

    Abstract Microencapsulation of neroline inside microcapsules having a polyurethane shell based on β-cyclodextrin (β-CD) and hexane diisocyanate was performed by interfacial polycondensation. The polyol nature of β-CD caused tight crosslinking of microcapsules wall. Microcapsules of neroline were characterized for their chemical composition and structure of the polyurethane shell by FTIR spectroscopy, thermogravimetric analysis, optical and electron microscopy, light scattering and electrophoresis measurements. Core content and encapsulation yield were 15% and 60%, respectively. Spherical microcapsules of mean diameter 29 μm were slightly cationic with an isoelectric point of 6.3. Neroline-loaded microcapsules were fixed on cotton fabric using More >

    Torres1 YA, CA Busso1, OA Montenegro2, HD Giorgetti2, HD Rodríguez2, D Bentivegna3

    Phyton-International Journal of Experimental Botany, Vol.79, pp. 195-198, 2010, DOI:10.32604/phyton.2010.79.195

    Abstract Osmotic adjustment has been recognized to be an important adaptive response to water stress in higher plants. Although Leymus cinereus cv. “Trailhead” is reputedly a very drought-tolerant rangeland plant, its ability to adjust osmotically in the field has not previously been reported. This study examined the occurrence or not of osmotic adjustment in field-grown plants of Leymus cinereus cv. “Trailhead” during late spring in an arid zone of Patagonia. Plants of this species had been established in the field three years before. With this purpose, leaf laminae of this species were collected and pressure-volume curves made. Results More >
