Arbuscular Mycorrhizal Fungi Associated with Maize ( L.) in the Formation and Stability of Aggregates in Two Types of Soil.

Knowledge of native Arbuscular Mycorrhizal Fungi (AMF) and their relationship with the edaphic characteristics where they live is important to establish the influence of allochthonous AMF, which were inoculated, on the development and stability of soil aggregates. The objectives of this research were to know the composition of native AMF species from two contrasting soils, and to establish the development and stability of aggregates in those soils with corn plants after inoculating them with allochthonous AMF. The experiment had three factors: Soil (two levels [S1 and S2]), HMA (three levels: without application [A0], with the application of [A1] and with the application of a consortium [A2]) and Fertilization (two levels (without fertilization [f0] and with fertilization [f1])).

Physiological Responses of to Inoculation with Autochthonous and Allochthonous Arbuscular Mycorrhizal Fungi.

The benefits of mycorrhizal interactions are only known in 8 of 210 recognized taxa. We evaluated the effects of autochthonous and allochthonous arbuscular mycorrhizal fungi (AMF) on growth and nutrient assimilation in . The autochthonous consortium (Cn) of eight species was propagated from the rhizospheric soil of , while (Cc) and (Ce) were employed as allochthonous AMF.

Effect of the temperature on the spray drying of Roselle extracts (Hibiscus sabdariffa L.).

The effect of the drying temperature on the volatile components and sensory acceptance of the Roselle (Hibiscus sabdariffa) extract in powder was investigated. The Roselle extraction was carried out by maceration with 7 L of 30% ethanol (v/v), 560 g of fresh Roselle calyces for 168 h. The Roselle extracts were spray dried at different temperatures 150, 160, 170, 180, 190, 200 and 210 degrees C, giving different outlet values about yield and final moisture.
