13. Use of response surface methodology to optimization of extraction of enzymes from pineapple pulp.
The enzymatic reactions are very important for food. They are responsíble for the formation of highly desirable cornpound, but can cause disorders and undesirable consequences. The physiological behaviour of vegetables and fruits is already known, so that most of its deterioration changes in flavour, colour and nutritional value are caused by enzymes of the

15. Induction of fruit tolerance to chilling injury: physiological and biochemical aspects / Indução de tolerância de frutos às injúrias de frio: aspectos fisiológicos e bioquímicos
Experiments were performed with the purpose to investigate physiological and biochemical responses associated to induction of fruit tolerance to chilling injury and the involvement of ethylene and antioxidant defense system in this process. Nanicão banana and Tahiti lime fruit were submitted to treatments to stimulate or to inhibit ethylene action and heat

16. Efeito do dano físico sobre o metabolismo de folhas de taioba, Xanthosoma sagittifolium (L.) Schott / Effects of wounding on the metabolism of tannia leaves, Xanthosoma sagittifolium (L.) Schott
Vegetables like leaves of tannia are subject to various factors which cause deterioration. Among these factors, mechanical damage triggers a series of physiological responses that occur at the site of the injury and surrounding tissues. The objective of this study was to evaluate the physiological responses of tannia leaves mechanical damaging, and whether t

17. Deterioração pós-colheita da mandioca minimamente processada / Posharvest physiological deterioration in minimally processed cassava roots
As raízes de mandioca apresentam alta perecibilidade pós- colheita, em função da deterioração fisiológica que se desenvolve nos locais injuriados, dois a três dias após a colheita em condições ambientais. A deterioração fisiológica é caracterizada pelo aparecimento de estrias azuladas na polpa, que progride por toda a extensão da raiz, sendo

18. Avaliação do potencial fisiológico e métodos de condicionamento, secagem e armazenamento de sementes de pepino / Evaluation of the physiological potential and priming, drying and storage of cucumber seeds
The objectives of this research were to identify reliable methods to evaluate the physiological potential of cucumber seeds, verify the relationship between seed physiological potential and field performance, as well as to define a suitable procedures for seed priming, drying and storage. The study was conducted in two experimental phases using seed lots of

19. Changes physiology and biochemistry of seeds of Melanoxylon brauna during deterioration / Alterações fisiológicas e bioquímicas de sementes de Melanoxylon brauna envelhecidas natural e artificialmente
The knowledge at present about the biochemical and physiologic changes in forest tree seeds is limited, as well as those of vigour evaluation testes during this stage. The objective of this work was to evaluate the physiological and biochemical changes of Melanoxylon brauna seeds during storage and the accelerated aging, establishing relations between these

20. Processamento mínimo, fisiologia e conservação refrigerada de genótipos de tomate / Physiology and refrigerated conservation of fresh-cut tomato genotypes
The purpose of this work was to evaluate the physiological characteristics of ripening and to describe the potential conservation of fresh-cut Firme and Alambra mutant tomatoes (long life), in relation to Santa Clara (normal) and F1 (Firme x Santa Clara) tomatoes. Fruits were harvested at ripening stage 4 and kept for 15 days at 12 C, except for Alambra, har

21. Envelhecimento acelerado e avaliação da qualidade fisiológica de sementes de trigo acondicionadas em diferentes embalagens e armazenadas em ambiente natural em Ibitirama-ES
The wheat is a grassy one, whose seeds present high germination. These works had had as objective to study the germination, the vigor and the storage of wheat seeds. In the study of the accelerated aging and experiment casualizado was lead in the completely randomized design, with four replications of 25 seeds. The temperatures (41, 43, 45C) and the adequate

22. Caracterização morfo-fisiológica e identificação de fragmentos de cDNA diferencialmente expressos de tegumentos de sementes de soja com permeabilidade contrastante / Morpho-physiologic characterization and identification of fragments of cDNA distinguishing expressed in soybean seed coat with contrasting permeability
Some works have reported the existence of contrasting soybean genotypes for physiological quality of seeds. There are such differences because of the presence of seeds with total or partial impermeability for water absorption into the coat that make them less susceptible to mechanical damages, weather adversities, deterioration by humidity and pathogen occur
