Email: [email protected]  1 RESUMO Objetivou-se identificar os efeitos da utilização de resíduo de carcinicultura sobre o crescimento e sistema enzimático antioxidativo de girassol em condições de estresse hídrico. O trabalho foi conduzido na casa de vegetação do Instituto Federal do Ceará – campus Maracanaú, Ceará, Brasil. As sementes foram semeadas em baldes contendo: 1) areia de granulometria fina; 2) areia + adubo; 3) areia + 7g de resíduo de carcinicultura; 4) areia + 14g de resíduo de carcinicultura. Decorridos 16 dias da semeadura, metade de cada grupo de plântulas descrito foi submetido à suspensão de rega. Foram realizadas 2 coletas:19 e 21 dias após a semeadura. Determinaram-se: as matérias frescas e secas da parte aérea, das raízes e total e as atividades das enzimas antioxidativas em folhas e raízes. De modo geral, a utilização de resíduo de carcinicultura no substrato proporcionou melhoria no crescimento das plantas. Isso pode ter ocorrido devido ao aumento nas atividades das enzimas antioxidativas. Em condições controle, a aplicação de 14g de resíduo ocasionou maiores produções de matéria seca total e atividades das enzimas antioxidativas. Concluiu-se que o resíduo de carcinicultura pode ser uma alternativa aos fertilizantes, reduzindo os custos de produção, além de ser uma destinação adequada ao resíduo de carcinicultura. Palavras-chave: estresse oxidativo, Helianthus annuus L., biofertilizante  BRAGA, B.

AEFFECTS OF SUPPLEMENTATION WITH WASTE OF SHRIMP FARMING ON SUNFLOWER PLANTS UNDER DROUGHT STRESS CONDITIONS  2 ABSTRACT The aim of this study was to identify the effects of the use of shrimp waste on plant growth and the antioxidative enzymatic defense system of sunflower under drought stress conditions. The experiment was carried out under greenhouse conditions at the Instituto Federal de Educação, Ciência e Tecnologia (Federal Institute of Education, Science and Technology), Maracanaú Campus, Ceará, Brazil. The seeds were sown in plastic pots containing: 1) fine-grained sand; 2) sand + fertilizer; 3) sand + 7g of shrimp waste; 4) sand + 14g shrimp waste. At 16 days after sowing, half of each seedling group described was submitted to irrigation suspension. Two plant harvests were performed: at 19 and 21 days after sowing. The following parameters were determined: shoots, roots and total fresh and dry masses, and activities of antioxidative enzymes in shoots and roots. In general, the use of shrimp waste in the substrate provided higher plant growth. This could be attributed to the increased activity of antioxidative enzymes. Under control conditions, the application of 14g of waste led to higher total dry mass and higher activities of antioxidative enzymes. It is concluded that the shrimp waste may be an alternative to fertilizers, reducing production costs.  Moreover, it seems to be an adequate disposal for shrimp farming waste. Keywords: oxidative stress, Helianthus annuus L., biofertilizer

In order to understanding proteomic basis of drought tolerance in sunflower (Helianthus annuus L.), two contrasting inbred lines were subjected to drought stress during the flowering stage for two years. Proteins were extracted from leaves of well-watered and drought-treated plants by using the TCA–acetone precipitation method and analysed by two-dimensional polyacrylamide gel electrophoresis followed by nanoscale liquid chromatography coupled to tandem mass spectrometry for identification of affected proteins. When comparing proteomic patterns, 18 proteins were changed by drought stress in sensitive lines and 24 proteins in tolerant lines. Concurrent down-expressions of oxygen-evolving enhancer and ferredoxin-NADP reductase were considered as primary drought sensors that mediate downstream pathways to cope with drought conditions. Differential and line-specific proteomic changes were attributed as the source for contrasting response to drought stress. According to the results, scavenging of reactive oxygen species, conservation of energy and water, and cell-structure integrity constituted the major aspects of drought tolerance in sunflower.
