    Mycorrhizal Networks Interacting with Litter Improves Nutrients and Growth for One Plant through the Vary of N/P Ratio under Karst Soil

    Liling Kang1, Yuejun He1,*, Lipeng Zang1, Jianpeng Si1, Ying Yang1, Kaiping Shen1, Tingting Xia1, Qiyu Tan1, Bangli Wu1, Yun Guo1, Wei Wang2, Qin Liang3

    Phyton-International Journal of Experimental Botany, Vol.90, No.3, pp. 701-717, 2021, DOI:10.32604/phyton.2021.014740

    Abstract Arbuscular mycorrhizae (AM) fungi affect nutrient uptake for host plants, while it is unclear how AM fungi interacting with soil litter affect plant growth and nutrient utilization through mycorrhizal networks in karst soil of deficient nutrients beyond the rhizosphere. An experiment was conducted in a microcosm composed of a planting compartment for Cinnamomum camphora seedlings with or without Glomus mosseae fungus (M+ vs. M ) and an adjacent litter compartment containing or not containing additional litter material of Arthraxon hispidus (L+ vs. L ), where the compartments are connected either by nylon mesh of 20 μm or 0.45 μm which either… More >

    Interaction of Acaena elongata L. with Arbuscular Mycorrhizal Fungi under Phosphorus Limitation Conditions in a Temperate Forest

    Phyton-International Journal of Experimental Botany, Vol.90, No.2, pp. 605-619, 2021, DOI:10.32604/phyton.2021.014208

    Abstract The aim of this study was to analyze the performance of Acaena elongata colonized by arbuscular mycorrhizal fungi (AMF) to different phosphorus (P) concentrations, as a measure of AMF dependency. A. elongata, is a species from soils where P availability is limited, such as temperate forests. Our research questions were: 1) How do different P concentrations affect the AMF association in Acaena elongata, and 2) How does the AMF association influence A. elongata’s growth under different P concentrations? A. elongata’s growth, P content in plant tissue, AMF colonization and dependency were measured under four P concentrations: control (0 g P kg−1More >

    Root traits and arbuscular mycorrhiza on perennial grasses exposed to defoliation after a controlled burning

    Ithurrart LS1,2, CA Busso1,2, YA Torres1,3, DV Peláez1,2,3, H Giorgetti4, G Rodríguez4, ML Ambrosino2,5

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 51-59, 2018, DOI:10.32604/phyton.2018.87.051

    Abstract Plant competition for soil resources is common in semiarid rangelands. Plants have various, alternative mechanisms to deal with soil resource acquisition. They include (1) length, weight and proliferation of roots, (2) root length density, and (3) root colonization by arbuscular mycorrhiza. In rangelands of Argentina, plants are exposed to herbivory after natural fires. As a result, knowledge on how these disturbances impact root traits is important for outlining guidelines focused on rangeland management and improvement. Our aim was to analyze the effects of defoliation after a controlled burning on root traits (1) to (3) on… More >
