Abstract:
... Disposal of iron slime, the by-product of steel industry, is a matter of environmental and ecological concern. A greenhouse experiment was conducted to study the potentiality of iron slime as an amendment in mitigating arsenic (As) accumulation and yield reduction of rice. The experiment was conducted in factorial completely randomized design with three levels of arsenic spiking: 0, 5, and 10 mg k ...

Abstract:
... Nutrients are often released heterogeneously over time (e.g., in pulses) in natural habitats. Different genotypes of the same plant species may vary in their responses to temporal nutrient heterogeneity so that temporal nutrient heterogeneity may influence intraspecific interactions. To test effects of temporal nutrient heterogeneity on intra-genet (competition between ramets of the same genotype) ...

Abstract:
... BACKGROUND: Individual plants can identify their neighbors and adjust their biomass investment to avoid competing with their relatives or jointly cope with external stresses. Maternal effects can improve their offspring adaptability under external stresses. However, how grazing-induced maternal effects influence plant kin interactions remain unknown. METHODS: Clonal offspring of Leymus chinensis g ...

Abstract:
... AIMS: We investigated the role of plants and their plant-derived carbon in shaping the microbial community that decomposes substrates and traced the return of nutrients from decomposition back to plant shoots in order to understand the importance of plants for ecosystem element cycling. METHODS: We performed a greenhouse experiment having plant communities with and without arbuscular mycorrhizal f ...

Abstract:
... Plants allocate resources to processes related to growth and enemy defence. Simultaneously, they interact with complex soil microbiomes that also affect plant performance. While the influence of individual microbial groups on single plants is increasingly studied, effects of microbial interactions on growth, defence and growth–defence relationships remain unknown, especially at the plant community ...

Abstract:
... High temperature during flowering increasingly reduces maize yield with warming climate. Heat tolerance of maize is however not fully understood in the aspect of flowering characteristics and yield stability, especially in the female flowering patterns. Temperature‐controlled greenhouse studies were conducted to test heat tolerances of four inbred lines and five hybrids, including 30/20 and 40/30° ...

Abstract:
... Biological nitrification inhibition (BNI) has been considered a plant strategy to increase N use efficiency by reducing N losses via N₂O emissions or nitrate leaching. However, recent studies have revealed no difference in gross nitrate production among Urochloa humidicola genotypes with previously described high- and low-BNI capacity and pointed towards a crucial role for microbial N immobilizati ...
... In this work, 75 quality protein maize (QPM) inbred lines were evaluated for aluminum tolerance using a nutrient solution assay in a laboratory and a soil-based technique in a greenhouse tunnel. The experiment was set up in a completely randomized design with three replications in the laboratory, and a randomized complete block design was used in the greenhouse. Aluminum toxicity was generated by ...
... Evidence suggests that the invasion of Spartina alterniflora (S. alterniflora) poses potentially serious risks to the stability of coastal wetlands, an ecosystem that is extremely vulnerable to both biological and non-biological threats. However, the effects and mechanisms of sulfur (S) in mediating the growth and expansion of S. alterniflora are poorly understood, particularly when sediments are ...

Abstract:
... Effect of tea pruning litter biochar (TPLBC) on arsenic (As), cadmium (Cd) and chromium (Cr) content in made tea and successive tea infusions were investigated in a greenhouse experiment with two tea cultivars (TV23 and S.3A/3). Made tea prepared from TV23 and S.3A/3 clone, a decrease in the concentration of As, Cd, and Cr by 36.73%, 16.22%, 13.96%, and 36.63%, 27.78%, 10.54%, respectively over co ...

Abstract:
... Tedera is a Mediterranean perennial herbaceous forage legume that remains green during summer and autumn with minimal leaf drop when grown in the medium to low rainfall zones of Western Australia. This unique attribute allows out-of-growing-season grazing that can complement the traditional grazing system based on winter annual species. Tedera is a traditional rangeland forage in the Canary Island ...

Abstract:
... Perfluoroalkyl and polyfluoroalkyl substances (PFAS) have been identified as emerging contaminants of public health concern. With PFAS now detected globally in a wide range of environments, there is an urgent need for effective remedial treatment solutions at the field scale. Phytoremediation presents a potential remediation strategy for PFAS that would allow efficient and cost-effective remediati ...
... Invasive species are detrimental to ecosystems worldwide, and long-term invasive treatment outcomes are generally poor. Integrating active restoration into an invasive species treatment plan by seeding with species that that can competitively suppress the invader may help to improve treatment outcomes. Buffelgrass is a drought tolerant perennial grass that is highly invasive and disruptive to dryl ...

Abstract:
... Greater plant diversity is known to facilitate soil C gains, yet the exact mechanisms of this effect are still under intensive discussion. Whether a plant grows in monoculture or in a multi-species mixture can affect allocation of plant assimilates, belowground exudation, and microbial stimulation. The goal of this study was to examine the effects of inter-cropping on a previously overlooked aspec ...
... Carbon (C) allocation strategy plays a critical role in plant adaptability, which are also important to assess the productivity stability under environmental change. Based on optimal partitioning theory, we asked two questions: (1) How is plant C allocation within tissues affected by nutrient enrichment (N addition)? And (2) does long‐term N addition alter how plants allocate C under drought? To a ...
... Cultivation of solanaceous vegetables such as eggplant and tomato is severely affected by bacterial wilt in the coastal regions of India. The causal agent Ralstonia pseudosolanacearum is soilborne bacterium, highly diverse, and able to survive in soil for many years without a host. Five bacterial wilt resistant eggplant (Solanum melongena) rootstock lines were evaluated by challenge inoculation an ...
... A dose-response relationship was documented throughout two-year greenhouse trial on chili in 2019 and 2020 wherein varying acquisition and inoculation times affected Chili leaf curl virus (ChLCV) transmission significantly. Transmissions of ChLCV to the highest levels were statistically equal between 42 and 48 hours acquisition and inoculation. ChLCV transmission by female whiteflies is far superi ...

Abstract:
... Clubroot, caused by Plasmodiophora brassicae, is a major disease of canola (Brassica napus). This study evaluated the effect of clubroot development on the yield of this crop under field and greenhouse conditions. Three canola cultivars, ‘45H31’ (susceptible), ‘45H29’ (1st-generation resistance) and ‘CS2000’ (2nd-generation resistance), were inoculated with different quantities of P. brassicae ino ...

Abstract:
... Changes in grassland management lead to alterations in community structure and can facilitate rapid expansion of both non-native and native invaders. Light availability differs greatly depending on grassland density, and competition for light is an important component of species dynamics. In this study, we examined if light reduction is an effective method to suppress a native invader in pre-alpin ...

Phytoremediation is one of the most studied ecofriendly low-cost solutions nowadays and halophytes species has been proved to have potential as bio-tools for this purpose. The extent to which salinity influences diesel tolerance in halophytes requires investigation. A greenhouse experi ...
