The objective of this research was to select the equation that best estimates the leaf area of the coffee tree Coffea dewevrei, from the linear dimensions of the leaves. For this purpose, 140 leaves of adult plants were collected from the Capixaba Institute for Research, Technical Assistance and Rural Extension, in the city of Linhares, North of the State of Espírito Santo, Brazil. The length (L), the width (W), the product of the multiplication between the length and width (LW) and the leaf area observed (OLA) were determined from all leaves. For the modeling, a 100 leaves sample was used, where OLA was used as a dependent variable in function of L, W and LW as independent variable, being obtained the following models: linear first degree, quadratic and power. For the validation, a sample of 40 leaves was used, where the values of L, W LW were substituted in the equations generated in the modeling, thus obtaining the estimated leaf area (ELA). A simple linear equation model was fitted for each modeling equation relating ELA in function of OLA. The hypotheses H0: β0 = 0 versus Ha: β0 ≠ 0 and H0: β1 = 1 versus Ha: β1 ≠ 1, were tested using Student's t test at 5% probability. The mean absolute error (MAE), root mean square error (RMSE) and Willmott's index d for all equations were also determined. The best model that estimates the area of Coffea dewevrei was chosen through the following criteria: β0 not different from zero, β1 not different from one, MAE and RMSE values closer to zero and index d closer to the unit. The area of the leaves can be determined by its greater width (W), through the quadratic model equation ELA=-10.255+1.020(W)+1.293(W)2.

O Brasil é o maior produtor e consumidor de maracujá-azedo (Passiflora edulis) e maracujá-doce (Passiflora alata) do mundo. O objetivo desse trabalho foi avaliar a capacidade germinativa e o vigor de sementes de diferentes cultivares de maracujá. As sementes das cultivares: FB 200 (Yellow Master), FB 300 (Araguari), BRS Gigante Amarelo, BRS Sol do Cerrado, BRS Rubi do Cerrado, BRS Sertão forte e BRS Pérola do Cerrado foram colocadas em câmara germinativa do tipo BOD, num delineamento inteiramente casualizado (DIC), com três repetições. Foram avaliadas as caracterÃsticas porcentagem de germinação (%G), Ãndice de velocidade de emergência (IVE), plantas normais fortes (PNFT), plantas normais fracas (PNFC) e sementes estragadas (SET). Houve efeito significativo para todas as variáveis estudadas, sendo observadas as maiores percentagens de germinação e IVE paras as cultivares FB 200 (Yellow Master), FB 300 (Araguari), BRS Sol do Cerrado e BRS Rubi do Cerrado, e os menores valores para a cultivar BRS Pérola do Cerrado. De modo geral, as cultivares que mais se destacaram foram a FB 200 (Yellow Master) e BRS Sol do Cerrado. |
