ESTRUCTURA Y SOMBRA DEL CAFETAL EN DOS LOTES DE LA FINCA LERIDA, ALTO QUIEL, BOQUETE
In order to evaluate the shade structure of the coffee plantation in lots four and five of Finca Lerida, Alto Quiel, Boquete, Province of Chiriqui, two sampling plots were established with an area of 10000 and 5800 square meters respectively; considering variables such as: tree vegetation structure, diversity of tree species ranging from 15 to 40 cm in diameter and photosynthetically active radiation (PAR). Tree species were evaluated: total height, basal area and crown diameter. The percentage of shade was obtained by the method of Werner (2009) using the concave densiometer, photosynthetically active radiation (PAR) was obtained with a quantum sensor, whose function is to measure the quality of light that stimulates growth of the plant. The results indicated that in lot four, 25 individuals of Inga vera Willd (guabo) were counted, with total height between 11.0 to 24.5 m, basal area with values of 0.02 to 0.11 m2 ha-1, the crown diameter of 6.25 to 12.80 m; in addition to four tree species of Citharexylum recurvatum Greenm (palomo), with a total height of 12 to 19 m, basal area of 0.02 to 0.05 m2 ha-1, the crown diameter of 4.2 to 8.8 m. In lot five, 30 Inga vera Willd individuals were registered; with total height in ranges from 6.5 to 20.0 m, basal area from 0.02 to 0.10 m2 ha-1 and crown diameter of 6.8 to 12.60 m. The photosynthetically active radiation (PAR), recorded in batch four, was 992.50 nanometers, corresponding to 28.9 percent shade. In batch five it was 865 nanometers with 68.9 percent shading.

Con el objetivo de evaluar la estructura de la sombra del cafetal en los lotes cuatro y cinco de la Finca Lérida, Alto Quiel, Boquete, Provincia de Chiriquí, se establecieron dos parcelas de muestreo con una superficie de 10000 y 5800 metros cuadrados respectivamente; considerando variables como: estructura de la vegetación arbórea, diversidad de especies de árboles con rangos de 15 a 40 cm de diámetro y radiación fotosintéticamente activa (RFA). A las especies arbóreas se les evaluó: altura total, área basal y diámetro de copas. El porcentaje de sombra se obtuvo mediante el método de Werner (2009), utilizando el densiómetro cóncavo; la radiación fotosintéticamente activa (RFA) se obtuvo con un sensor cuántico, cuya función es la de medir la calidad de la luz que estimula el crecimiento de la planta. Los resultados indicaron que en el lote cuatro se contabilizaron 25 individuos de Inga vera Willd (guabo), con altura total entre 11.0 a 24.5 m, área basal con valores de 0.02 a 0.11 m2 ha-1, el diámetro de copa de 6.25 a 12.80 m; además de cuatro especies arbóreas de Citharexylum recurvatum Greenm (palomo), con altura total de 12 a 19 m, área basal de 0.02 a 0.05 m2 ha-1, el diámetro de copa de 4.2 a 8.8 m. En el lote cinco se registraron 30 individuos de Inga vera Willd; con altura total en rangos de 6.5 a 20.0 m, área basal de 0.02 a 0.10 m2 ha-1 y diámetro de copa de 6.8 a 12.60 m. La radiación fotosintéticamente activa (RFA), registrada en el lote cuatro fue de 992.50 nanómetros correspondiendo a un 28.9 por ciento de sombra. En el lote cinco fue de 865 nanómetros con un 68.9 por ciento de sombra.
