    Abstract Food waste is recognized as a valuable source for potential agricultural applications to supply organic matter and nutrients to arable soil. However, the information on the combined application of food waste and the plant growth-promoting bacterial strain, Chlorella, related to plant metabolic features and sodium chloride content in arable soil is limited. The present study was conducted to investigate the exogenous application of food waste along with Chlorella, which improved the physio-morphological features of red pepper. Our results revealed that this combination enhanced the organic matter in the soil, ultimately improving the fertility rate of the soil, and the physio-morphological… More >

    Elizabeth Carrillo-Flores1, Jonanci Arreola-Rivera1, Denní Mariana Pazos-Solís2, Moisés Bocanegra-Mondragón2, Grisel Fierro-Romero3, Ma. Elena Mellado-Rojas1, Elda Beltrán-Peña1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.11, pp. 2383-2401, 2022, DOI:10.32604/phyton.2022.021507

    Abstract The potential of Plant Growth Promoting Rhizobacteria (PGPR) has been demonstrated in the case of plant inoculation with bacteria of the genus Azospirillum which improves yield. A. brasilense produces a wide variety of molecules, including the natural auxin indole-3-acetic acid (IAA), as well as other phytoregulators. However, several studies have suggested that auxin induces changes in plant development during their interaction with the bacteria. The effects of A. brasilense Sp245 on the development of Arabidopsis thaliana root were investigated to help explain the molecular basis of the interaction. The results obtained showed a decrease in primary root length from the… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.2, pp. 257-278, 2022, DOI:10.32604/phyton.2022.016512

    Abstract Phosphorus (P) is a critical nutrient that plays an essential role in improving soil fertility for optimum plant growth and productivity. It is one of the most deficient macro-nutrients in agricultural soils after nitrogen and is considered inadequate for plant growth and production. To P availability in soils, the farmers are applying huge amounts of synthetic P fertilizers that adversely affect the wider environment, groundwater, soil fertility and microbial population. Many beneficial microbes are known to release and supply soluble P for improving growth and yield of a variety of plants in a sustainable manner in P deficient soils. Thus,… More >

    Multi-strain Inoculation with PGPR Producing ACC Deaminase is More Effective Than Single-strain Inoculation to Improve Wheat (Triticum aestivum) Growth and Yield

    Muhammad Zafar-ul-Hye1,*, Misbah Batool Zahra1, Subhan Danish1, Mazhar Abbas2, Abdur Rehim1, Muhammad Naeem Akbar1, Ayesha Iftikhar1, Mehreen Gul1, Ifat Nazir1, Maria Abid1, Muhammad Tahzeeb-ul-Hassan1, Maria Murtaza3

    Phyton-International Journal of Experimental Botany, Vol.89, No.2, pp. 405-413, 2020, DOI:10.32604/phyton.2020.08918

    Abstract Rhizosphere bacteria that colonize plant roots and confer beneficial effects are referred as plant growth promoting rhizobacteria (PGPR). Among all PGPR, some rhizobacteria have an ability to produce ACC deaminase enzyme. This enzyme catalyzes stress ACC into a-ketobutyrate and ammonia instead of letting it to be converted to ethylene. Ethylene level rises in plants under stress conditions i.e., drought, salinity, poor soil fertility etc. As poor soil fertility is a big hurdle to achieve the optimum yield of crops, inoculation of ACC deaminase PGPR can overcome this problem to some extent. The aim of the current study was to examine… More >

    Phyton-International Journal of Experimental Botany, Vol.83, pp. 133-138, 2014, DOI:10.32604/phyton.2014.83.133

    Abstract The response of cherry tomato to biofertilization with beneficial microorganisms was evaluated under shadehouse conditions. Seeds were inoculated and/or co-inoculated with Azospirillum brasilense (Az) and/or Glomus intraradices (Gi). Thereafter, seedlings of six treatments received two applications of a suspension containing Az + Gi at 15 and 30 days after the transplant, and were compared against a non-inoculated treatment which only received conventional inorganic fertilization. Seed co-inoculation with A. brasilense and G. intraradices plus two applications of Az + Gi at 15 and 30 days after transplant increased on average 6% plant height, 11% leaf area, 10.5% dry biomass and 16%… More >

    Castillo-Aguilar C de la C1, JJ Zúñiga-Aguilar2, AA Guzmán-Antonio2, R Garruña3

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 199-204, 2017, DOI:10.32604/phyton.2017.86.199

    Abstract The Habanero pepper (Capsicum chinense) is intensively cultivated in the Yucatan peninsula, México. Because of adverse environmental conditions, it required seeding in germination trays, from which six-week-old seedlings were transplanted to the soil. Adequate nursing and fertilization programmes were made to improve health and vigour before seedlings transplanting. During seed germination, we investigated the effects of inoculation with four plant growth-promoting rhizobacteria (PGPR) on growth, nutrient uptake and gas exchange of 8-week-old Capsicum chinense plants. Inoculation was made with Pseudomonas sp. -P61-, Pseudomonas sp. -A46-, Bacillus pumillus -R44-, and Paenibacillus polymyxa-BSP1.1-. The BSP1.1 strain produced the highest increase in plant… More >

    Iqbal A1, MA Iqbal1, A Iqbal1, Z Aslam1, M Maqsood1, Z Ahmad2, N Akbar1, HZ Khan1, RN Abbas1, RD Khan1, G Abbas1, M Faisal1

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 84-88, 2017, DOI:10.32604/phyton.2017.86.084

    Abstract Seed inoculation with bacterial species has the potential to increase yield and agro-qualitative attributes of forage crops. This study determined the response of forage maize to three plant growth promoting rhizobacteria [PGPR1 (Azotobacter chroococcum), PGPR2 (Pseudomonas flourescens) and PGPR3 (Bacillus megaterium)] inoculated individually and in different combinations (PGPR1+2, PGPR1+3, PGPR2+3 and PGPR1+2+3). A non-inoculated treatment was kept as a control. We used a completely randomized block design with four replicates. The PGPR1+2+3 treatment showed an outstanding performance by improving yield attributes, green forage yield, dry matter biomass, crude protein and total ash. The same treatment gave the lowest crude fiber… More >

    Microbial inoculation of Parkinsonia praecox (Ruiz & Pav. ex Hook.) Hawkins for ecological restoration

    Álvarez AS1, DR Pérez2

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 274-279, 2018, DOI:10.32604/phyton.2018.87.274

    Abstract The use of microbial inocula for the restoration of severely degraded arid environments is of great interest. This is because there is a presumption that growth-favoring microorganisms can facilitate the establishment of seedlings by increasing their ability to withstand both the stress of transplantation in the case of nursery seedlings, and the extreme conditions for natural establishment imposed by the scarce, random and variable rainfall. In this work we analyze the “slenderness index”- the height of the plant divided by its diameter at the height cotyledon node- to analyze the effect of treatments with microorganisms in the nursery. This variable… More >
