Abstract:

Harnessing the abilities of soil microbes to improve plant health and productivity may be an important factor in obtaining food security for the future. In this study, 179 potential plant growth-promoting bacteria (PGPB) were isolated from the rhizosphere of five types of plants from three Western Australian soils. On the basis of in vitro plant growth promotion assays, seven isolates were selected for testing in field trials in Western Australia. Two of the PGPB, Burkholderia caledonica NCH45 and Enterobacter soli ANMK1, improved the yield of wheat by 23% and 9% respectively. The isolate, Pse

Abstract:

Developing no-chemical strategies for the control of soil borne pathogens is one of the major issues for the cultivation of leafy vegetables. The application of Biological Control Agents (BCAs) represents a valuable approach and nowadays some biocontrol products are available on the market for greenhouse and field applications. However, these products often show lack of consistency and variable results mainly due to the poor knowledge about their biology and modes of applications and how the agroecosystem components modulate their efficacy. Streptomycetes are soil inhabitants and have an impo

Abstract:

Mining activities and their resulting wastes, mine tailings, have created a sizable problem globally. Semiarid lands have been particularly impacted due to intense mining activities in these areas. Growing concerns regarding human health risks and environmental consequences associated with these tailings has created a need for efficient and effective remediation strategies. Phytostabilization, the establishment of a vegetative cover on mine tailings to reduce erosion and dispersion of material, is emerging as a cost-effective remediation technology. However, due to elevated levels of metal

Abstract:

Environmental stresses are main factors limiting crop production worldwide. Water stress is a primary cause of crop losses, reducing average yields for most of the major crops by more than 50%, particularly in arid and semi-arid regions. Moreover, the increasing frequency of dry periods in many regions of the world, as a consequence of the global warming, frequently results in saline soils with low agricultural potential. Bacteria are among the first colonizers of soil habitats at different stages of development, largely contributing in determining soil structure and composition. In this conte

Abstract:

Excessive metal deposition in soil is of major concern to the environment due to the toxicity of metals to animals and plants. Since metals do not degrade, reducing risk of exposure relies in either removing the metals from soil, or changing their speciation which leads to changes in bioavailability, mobility and toxicity. Plants have been shown to provide a cheap alternative to chemical methods for both removing and changing metal speciation, particularly when augmented with plant growth promoting bacteria. The focus of this thesis was to investigate whether the form (speciation) in which a m

Studies on plant growth-promoting rhizobacteria (PGPR) and fungi (PGPF) as biostimulants have shown significant positive effects on plant health, fruit yield, or pest management.

The worldwide occurrence of sites contaminated with toxic metals and the associated high costs of remediating them using chemical and mechanical methods have led to calls to develop inexpensive and sustainable approaches based on the use of plants that naturally accumulate large amounts of metals in their tissues.

However, the growth of phytoremediators is often retarded under high soil metal concentrations, rendering them ineffective. Meanwhile, some plant

Abstract:

En raison de leur capacité à former une symbiose avec des bactéries du sol appelées Rhizobium, ces bactéries fixent l’azote atmosphérique et leurs plantes-hôtes n’ont donc pas besoin de fertilisant azoté, les légumineuses jouent un rôle important dans l'agriculture. En outre, certaines souches de Rhizobium ont la capacité de solubiliser le phosphate, fournissant ainsi du phosphore assimilable aux plantes hôtes. Une aptitude à lutter contre certains agents pathogènes a aussi été démontrée dans plusieurs études. La présente étude évalue l’efficacité symbiotique de rhizobiums tunisiens, leur capa

Abstract:

O desenvolvimento de tecnologias alternativas que visem aumentar a disponibilidade e eficiência do uso dos recursos minerais para as plantas aparecem como importante medida para se alcançar um crescimento sustentável da agricultura. Neste contexto, o suprimento de nitrogênio por meios biológicos, utilizando micro-organismos diazotróficos, dos quais os mais estudados são os rizóbios associados simbioticamente às leguminosas, é uma importante alternativa. Porém o sucesso atingido com essa simbiose em leguminosas ainda não foi alcançado em outras famílias de plantas, principalmente por limitações

Les plantes se développent et évoluent en interaction avec les organismes du sol. L'impact des vers de terre sur la croissance des plantes, généralement positif, a été attribué à des modifications physiques, chimiques ou biochimiques du sol, souvent sans démonstration rigoureuse. Dans ce travail, les techniques développées en sciences du végétal (culture in vitro, utilisation de mutants et transcriptomique) ont été utilisées afin de comprendre les mécanismes à l'origine de l'effet des vers de terre sur les plantes.

A estimativa da safra mundial de soja em 2015/16 apresentou uma redução na produção global da oleaginosa para 319,0 milhões de ton, volume 1,1 milhão de ton inferior ao levantamento de dezembro de 2015. Ainda assim, trata-se de um volume recorde. Para o milho, a produção global foi de 967,9 milhões de ton, com uma redução no volume de 5,9 mil

Abstract:

The present work aimed to evaluate the influence of different methods of plant growth promoting bacterium (PGPB) Azospirillum brasilense inoculated at vegetative development and grain yield of corn in different relief zones. The research was carried in Cruzeiro do Sul (RS) with mechanized sowing of Velox TL® very early hybrid corn, in the 2015/2016 harvest. The treatments were: seed Inoculation and nitrogen fertilization (T1); directed spraying in furrow and nitrogen fertilization (T2); and control, only with nitrogen fertilization (T3). The experimental design was a factorial 3x3, considering
