    Organ Abscission in Plants: With Special Emphasis on Bell Pepper

    Ramiro Reyes-Castro1, Héctor G. Núñez-Palenius1,*, Juan I. Valiente-Banuet2, María E. Sosa-Morales1, Blanca E. Orosco-Alcalá1, Rafael Guzmán-Mendoza1, Graciela M. L. Ruiz-Aguilar1, Rogelio Costilla-Salazar1

    Phyton-International Journal of Experimental Botany, Vol.93, No.7, pp. 1467-1484, 2024, DOI:10.32604/phyton.2024.051644

    Abstract Bell pepper (Capsicum annuum L.), along with potato and tomato, is one of the three most cultivated vegetables in the world. Bell pepper is worldwide accepted due to its characteristics of color, smell, flavor, and texture. Bell pepper is also considered a nutritious food due to its vitamin and antioxidant contents. In Mexico, bell pepper production has a high value because it is grown for the international markets, particularly the United States of America. Nevertheless, the abscission of flowers and fruits is a factor that limits the yield, hinders the planning of activities, and causes a More >

    Role of foliar spray of plant growth regulators in improving photosynthetic pigments and metabolites in Plantago ovata (Psyllium) under salt stress–A field appraisal

    Abstract Salinity is one of the major abiotic factors that limit the growth and productivity of plants. Foliar application of plant growth regulators (PGRs) may help plants ameliorate the negative impacts of salinity. Thus, a field experiment was conducted at the Botanical Garden University of Balochistan, Quetta, to explore the potential role of PGRs, i.e., moringa leaf extract (MLE; 10%), proline (PRO; 1 µM), salicylic acid (SA; 250 µM), and thiourea (TU; 10 mM) in ameliorating the impacts of salinity (120 mM) on Plantago ovata, an important medicinal plant. Salinity hampered plant photosynthetic pigments and metabolites but… More >

    Effects of Rhizoglomus intraradices, Azospirillum brasilense and plant growth regulators application on root architecture in barley (Hordeum vulgare L.)

    Zepeda-Guzmán S1, M Gómez-Romero2, C Sosa-Aguirre1, J Villegas1

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 183-190, 2018, DOI:10.32604/phyton.2018.87.183

    Abstract Changes in root architecture are a strategy used by plants to explore the soil for available resources. The presence of beneficial microorganisms in the rhizosphere as well as plant growth regulators can cause changes in root development and promote the availability of water and nutrients. The effect of microorganisms or growth regulators on plant growth has been tested, but little is known about the effect they have on the architecture of the root of Hordeum vulgare L. Therefore the objective of this study was to evaluate the effect of the application of Rhizoglomus intraradices, Azospirillum brasilense, quercetin… More >

    Inhibitory effect of jasmonic acid and ethylene on epicotyl growth and bud induction in the maritime pine, Pinus pinaster Soland. in Ait

    MARIA TERESA MARTIN2*, HILDA PEDRANZANI3, PATRICIA GARCÍA-MOLINERO2, VALENTIN PANDO4, ROSARIO SIERRA-DE-GRADO1

    BIOCELL, Vol.33, No.3, pp. 141-148, 2009, DOI:10.32604/biocell.2009.33.141

    Abstract Two independent parameters, epicotyl height (cm) and number of induced buds were studied on Pinus pinaster explants to analyse the effects of three phytohormones (6-benzylaminopurine, jasmonic acid, ethylene) which were combined or not in 11 different treatments. Epicotyle length diminished significantly in relation to the control medium (medium without exogen phytohormones) in presence of jasmonic acid, 6-benzylaminopurine or Ethephon (which is converted to ethylene in plants) in any of treatments. Concentrations of 100 μM of jasmonic acid and Ethephon had a greater inhibitory effect than the treatments with 10 μM. In addition to that, jasmonic acid… More >
