Assessment of mycorrhizal colonisation and soil nutrients in unmanaged fire-imp...

The mycorrhizal colonisation of plants grown in unmanaged soils from two restoration sites with a fire history in Northern Portugal was evaluated from the perspective of supporting restoration programmes. To promote restoration of original tree stands, Quercus ilex L. and Pinus pinaster Ait. were used as target species on two sites, denoted Site 1 and 2 respectively. The aim of the study was to assess whether m...

Impact of acute exposure to air pollution on the cardiorespiratory performance ...

The objective of the present study was to determine the impact of acute short-term exposure to air pollution on the cardiorespiratory performance of military fireman living and working in the city of Guarujá, São Paulo, Brazil. Twenty-five healthy non-smoking firemen aged 24 to 45 years had about 1 h of exposure to low and high levels of air pollution. The tests consisted of two phases: phase A, in Bertioga, a ...

Evolução molecular in vitro: seleção de moléculas inseticidas para insetos-prag...

O bicudo-do-algodoeiro (Anthonomus grandis) e a lagarta do cartucho (Spodoptera frugiperda) são insetos que causam perdas significativas para a agricultura devido aos danos causados à cultura do algodão. Estratégias biotecnológicas utilizam proteínas envolvidas com a defesa de plantas, incluindo as d-endotoxinas e os inibidores de a-amilases (aAIs), como ferramentas no desenvolvimento de plantas resistentes aos...

Studies on the diversity of arbuscular mycorrhizal fungi and the efficacy of tw...

A field survey of the arbuscular mycorrhizal status of herbaceous plant species was conducted in a highly alkaline anthropogenic sediment resulting from the disposal of waste from an acetylene and polyvinyl chloride factory. Most plant species found at the site were mycorrhizal and the dominant mycotrophic plant species was Conyza bilbaoana. Fungal species richness was assessed by identification of spores extra...

Synergistic effect of Glomus intraradices and Frankia spp. on the growth and st...

The presence of actinorhizas and arbuscular mycorrhizas may reduce plant stresses caused by adverse soil conditions. A greenhouse experiment was conducted using a sediment with a high pH, resulting from the disposal of waste originated at an acetylene and polyvinylchloride factory, in which Black alder (Alnus glutinosa) seedlings were inoculated either with Glomus intraradices BEG163 (originally isolated from t...

Venda livre de Sorocea bomplandii Bailon como Espinheira Santa no município de ...

Este trabalho surgiu da observação de que a espécie vendida livremente nas feiras e bancas populares do município do Rio de Janeiro (RJ) difere botanicamente de Maytenus ilicifolia Mart. Ex. Reiss (Celastraceae), comercializada industrialmente (e com uso reconhecido e registrado no Ministério da Saúde) como Espinheira Santa. Por comparação botânica foi constatado que nenhuma das espécies recolhidas correspondia...
