RESUMO:
Uma alternativa de manejo das doenças de citros causadas por Phytophthora spp. é o uso de matéria orgânica. Com o objetivo de avaliar os efeitos da incorporação de lodo de esgoto ao solo na indução de supressividade a Phytophthora nicotianae Breda de Haan (1896) em plântulas de limão cravo (Citrus lemonia (L.) Osbeck), foram realizados diversos experimentos em laboratório, casa de vegetação e campo. O aumento nas doses de lodo de esgoto, nos experimentos em laboratório, em casa de vegetação e em campo, resultou na redução do pH e aumento da condutividade elétrica do solo; aumento da atividade microbiana do solo (avaliada pela hidrólise de diacetato de fluoresceina ? FDA e pela respiração microbiana); além de uma redução na recuperação de P. nicotianae, tanto do substrato e do solo como das raízes de plântulas e mudas. Em alguns experimentos, a recuperação do patógeno correlacionou-se significativa e negativamente com a atividade microbiana do solo(FDA) e com a condutividade elétrica. Um melhor desenvolvimento de plântulas e mudas foi observado com a incorporação de lodo até 20%. Esses resultados indicam um efeito supressivo do lodo de esgoto a P. nicotianae, nas condições avaliadas, explicado por fatores químicos e biológicos. Dentre os fatores químicos destacam-se o aumento da condutividade elétrica e a inibição do crescimento das colônias do patógeno em meio de cultura com extratos ácidos de lodo. Os fatores biológicos envolveram o aumento da atividade microbiana do solo e a presença de fungos (Aspergillus sp. e Trichoderma sp.) e actinomicetos antagonistas a P. nicotianae.

SUMMARY:
Soil organic matter amendments may provide an alternative for the management of citrus soil diseases caused by Phytophthora spp. The effects of incorporating residential sewage sludge into the soil in order to induce suppressiviness to Phytophthora nicotianae Breda de Haan (1896) in seedlings and plantlets of rangpuor lime (Citrus limonia (L.) Osbeck) were evaluated. For this, several experiments under laboratory, greenhouse and field conditions were conducted. In almost all experiments, while sewage sludge doses enlarged, soil pH values decreased and soil electrical conductivity increased; soil microbial activity (evaluated by the fluorescein diacetate hydrolysis ? FDA and microbial respiration) increased, and P. nicotianae recovery from soil and roots tended to decreased. In some experiments, significantly and negative correlations were observed between P. nicotianae recuperation and microbial activity (FDA), and between P. nicotianae recuperation and soil electrical conductivity. Seedlings and plantlets development improved at a maximum of 20% v/v sewage sludge soil incorporation. These results suggest a sewage sludge suppressive effect on P. nicotianae, explained by chemical and biological factors, under the experimental conditions of the tests performed. Among chemical factors, the increase of the soil electrical conductivity and colony growth inhibition of P. nicotianae on culture media amended with an acid sewage sludge extract, were indicated. The biological factors involved in suppressiviness were the increase of soil microbial activity and the presence of fungi (Aspergillus sp. and Trichoderma sp.) and actinomyces antagonistic to P. nicotianae.

Abstract:
Technological (processing performance and end-product) and nutritional quality of wheat is in principle determined by a number of compounds within the wheat grain, including proteins, polysaccharides, lipids, minerals, heavy metals, vitamins and phytochemicals, effecting these characters. The genotype and environment is of similar importance for the determination of the content and composition of these compounds. Furthermore, the interaction between genotypes and the cultivation environment may play a significant role. Many studies have evaluated whether the genotype or the environment plays the major role in determining the content of the mentioned compounds. An overall conclusion of these studies is that except for compounds encoded by single major genes, importance of certain factors mainly depend on how wide environments and how diverse cultivars are within these comparative studies. Comparing environments all over, e.g. across Latin America, ends up with a high significance of the environment while large studies including genotypes of wide genetic background result in a significant role for the genotype. In addition, for some technological properties and components, genotype has a higher effect (e.g. grain hardness and gluten proteins), while environment influences stronger on others (e.g. protein and mineral content).Content and concentration of proteins, but also to some extent of starch, some non-starch polysaccharides and lipids, are essential in determining the technological quality of a wheat flour. For nutritional quality of the flour, the majority of the compounds are together the important determinant. Thus an increased understanding of environmental effects is essential. As to how the environment is influencing the content of the compounds, there are some differences. The protein content and composition is strongly affected by environmental factors influencing nitrogen availability and cultivar development time. However, these two factors are impacted by a range of environmental (temperature, precipitation, humidity/sun hours, etc.) and agronomic (soil properties, crop management practices such as seeding density, nitrogen fertilizer application timing and amount, etc.) components. Thus, to understand the interplay between the various environmental and agronomic factors impacting the technological quality of a wheat flour, modeling is a useful tool. Several other compounds, including minerals and heavy metals, are to a higher extent determined by site specific variation, resulting in similar rankings of entries across locations, although the total content is varying among years. The bioactive compounds and vitamins are a part of the defense mechanisms of plants and thus there is a variation in these compounds depending on prevailing biotic and abiotic stresses (heat, drought, excess rainfall, nutrition, diseases and pests). Thus, even for nutritional quality of wheat, incorporating all compounds of relevance in the evaluation would benefit from modeling tools. MenosAbstract:
