Título:  Intensity of bitterness of processed Yerba Mate leaves originated in two contrasted light environments.

Conteúdo:  The bitterness intensity of beverage prepared from the leaves produced on the males and females of yerba mate (Ilex paraguariensis), grown in the forest understory and monoculture, was evaluated. The leaves were grouped by their position (in the crown and on the branch tips) and by the leaf age. The leaf gas exchange, leaf temperature and photosynthetic photon flux density were observed. Inter and intra-specific competition for light and self-shading showed the same effect on yerba mate beverage taste. All the shading types resulted in bitterer taste of the processed yerba mate leaves compared to the leaves originated under the direct sun exposure. The leaves from the plants grown in the monoculture showed less bitterness than those grown in the forest understory. This conclusion was completely opposite to the conventionally accepted paradigm of the yerba mate industries. The leaves from the tips (younger leaves) of the plants grown in the monoculture resulted a beverage of softer taste; the males produced less bitter leaves in any light environment (forest understory or in the crown in monoculture). The taste was related to the photosynthetic and transpiration rate, and leaf temperature. Stronger bitterness of the leaves provided from the shade conditions was related to the decreased leaf temperature and transpiration in the diurnal scale.

Conteúdo:  The sustainable agriculture requires the use of advanced and modern technologies with the capacity to increase productivity to feed a world growing population demand. In this context, plant breeding associated with the studies of the rhizosphere microbiome may be an innovative strategy in plant protection against soil-borne pathogens. However, few studies investigate the structure and biodiversity of microbial communities in ancestral genotypes and recent cultivars associated with the plant defense process. Thereby, considering the impact of domestication and plant breeding on interactions in the plant rhizosphere microbiome, in this study, we compared the tolerance level of ancestral and recent wheat genotypes to Bipolaris sorokiniana and its correlation with the recruitment of bacteria in the rhizosphere. We evaluated the variation in susceptibility of eight wheat genotypes by inoculating the soilborne pathogen in the soil six days after sowing. The level of disease was assessed four weeks after inoculation. The two most contrasting genotypes, considering resistance against the soil pathogen, were selected for correlation analyzes with the structure of microbial communities in the rhizosphere. IAC 5 Maringá was found as the most resistant genotype to the pathogen and enrichment of Acidobacteria, Chloroflexi, Rhizobiaceae, and Cyanobacteria when compared with Guamirim, the susceptible genotype. In conclusion, the results suggest that the level of disease resistance correlat... Mostrar Tudo
