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.

Papaya (Carica papaya L.) is a fruit tree of great economic and food interest worldwide. Its propagation can occur both sexually and asexually. Traditionally, it is propagated by seeds; however, vegetative propagation has been often used with the use of in vitro and ex vitro culture techniques. In vegetative propagation, the cutting method has been extensively explored. Research has also been developed using grafting. In recent years, papaya cultivation has also become a model for other fruit plants in the use of biotechnological techniques aiming applications ranging from germplasm conservation to genetic transformation of plants. Since the beginning of the 1970s, the culture of papaya tree tissues has been intensely studied, allowing greater control of in vitro development, especially for micropropagation, organogenesis and somatic embryogenesis techniques.
O mamoeiro (Carica papaya L.) é uma fruteira de bastante interesse econômico e alimentar em todo o mundo. Sua propagação pode ocorrer tanto por via sexuada como assexuada. Tradicionalmente é propagado por sementes, entretanto, a propagação vegetativa vem sendo frequentemente utilizada com o uso de técnicas de cultura in vitro e ex vitro. Na propagação vegetativa o método de estaquia tem sido bastante explorado. Pesquisas também tem sido desenvolvidas utilizando-se a enxertia. A cultura do mamoeiro tem se tornado também, nos últimos anos, um modelo para outras fruteiras no que diz respeito ao uso de técnicas biotecnológicas, visando aplicações que vão da conservação de germoplasma a transformação genética de plantas.
