Este trabalho foi realizado para estudar a utilizacao da farinha de milho pre-gelatinizada em pasta alimenticias, a varios niveis de diluicao. A pre-gelatinizacao da farinha de milho foi obtida submetendo-a ao tratamento a vapor. O tipo de massa foi "spaghetti", sem alteracao no seu processamento. Ate 30% de diluicao, os produtos nao mostraram alteracao nas suas caracteristicas. Concluiu-se que e possivel obter-se massa alimenticia de boa qualidade com farinha mista, utilizando-se farinha de milho ate aquela diluicao. |

Background: Photosynthesis can be roughly separated into biochemical and photochemical processes. Both are affected by drought and can be assessed by non-invasive standard methods. Gas exchange, which mainly assesses the first process, has well-defined protocols. It is considered a standard method for evaluation of plant responses to drought. Under such stress, assessment of photochemical apparatus by chlorophyll fluorescence needs improvement to become faster and reproducible, especially in growing plants under field conditions. For this, we developed a protocol based on chlorophyll fluorescence imaging, using a rapid light curve approach. Results: Almost all parameters obtained by rapid light curves have shown statistical differences between control and drought stressed maize plants. However, most of them were affected by induction processes, relaxation rate, and/or differences in chlorophyll content; while they all were influenced by actinic light intensity on each light step of light curve. Only the normalized parameters related to photochemical and non-photochemical quenching were strongly correlated with data obtained by gas exchange, but only from the light step in which the linear electron flow reached saturation. Conclusions: The procedure developed in this study for discrimination of plant responses to water deficit stress proved to be as fast, efficient and reliable as the standard technique of gas exchange in order to discriminate the responses of maize genotypes to drought. However, unlike that, there is no need to perform daily and time consuming calibration routines. Moreover, plant acclimation to the dark is not required. The protocol can be applied to plants growing in both controlled conditions and full sunlight in the field. In addition, it generates parameters in a fast and accurate measurement process, which enables evaluating several plants in a short period of time.
