O objetivo deste trabalho foi desenvolver marcadores para a avaliação da personalidade no Modelo dos Cinco Grandes Fatores uso Brasil, funcionalmente equivalente ao inventário de Goldberg (1992). Participaram estudo 976 estudantes diversas universidades região sul do ambos os sexos. Os sujeitos se auto-descreveram, respondendo um instrumento previamente desenvolvido, que continha 96 termos (adjetivos) obtidos através piloto examinou cerca 180 descritores traços frequentemente utilizados em...
ABSTRACT Specialty coffees can be differentiated in various ways, including the environmental conditions which they are produced and sensory composition of drink. This study aimed to evaluate effect altitude, slope exposure fruit color on attributes cafes region Matas de Minas. Sampling points were georeferenced four altitude ranges (< 700 m; ≤ x 825 m, < 950 m ≥ m) coffee crop; two colors var. Catuaí (yellow red); exposures (North-facing South-facing). Coffee at cherry stage processed...
Com os objetivos de avaliar o grau suscetibilidade e caracterizar as injúrias na morfoanatomia folhas Magnolia ovata, mudas foram submetidas à chuva simulada com flúor (10 µg.ml-1 F-) por 10 dias consecutivos. No tratamento controle, utilizou-se apenas água deionizada. Folhas coletadas para quantificação matéria seca fixadas análises em microscopia luz eletrônica varredura. As apicais apresentaram pequena porcentagem necroses intervenais marginais uma ou ambas faces maior acúmulo flúor,...
Abstract: Tomato is a crop sensitive to water deficit and the responses of seeds germination under these conditions involve biochemical, physiological, molecular processes. The aim this study was evaluate physical, biochemical changes in tomato osmoprimed with selenium (Se) subjected during germination. LA 4050 3475 accessions were PEG 6000 solution (-1.0 MPa) plus Na2SeO4 (12.5 μM) or only for 24 h unprimed. from different treatments (-0.3 control (0 MPa). Image analyses performed (X-ray),...
Abstract: Post-harvest storage of fleshy fruit is a strategy used for improving seed quality. The aim this study was to evaluate post-harvest the C. baccatum var. (cumari pepper) and relate it antioxidant enzyme activity physiological potential. Red-colored (65 days after anthesis) gathered stored at 20 °C 0, 5, 10, 15, days. seeds were removed evaluated moisture content, quality, activity, protein content. means fitted regression equations then passed through multivariate analysis (PCA)....
Vigor tests are important mainly to identify differences associated lots performance in field conditions. The objective of this study was define the most appropriate evaluate crambe (Crambe abyssinica) seeds vigor. Seven seed were subjected standard germination (on first and last count), speed index (GSI), primary root protrusion (PRPSI), seedling length dry weight seedling, water stress test using PEG 6000 at -0.2 MPa, electrical conductivity cold without soil. Crambe studied had...
