ESTUDIO PARA LA DETERMINACIÓN DEL ÁREA FOLIAR EN ESPECIES ARBUSTIVAS
Abstract
Given the interest and importance of the leaf area, it is necessary that simple and efficient methods to determine it should be found. With this aim, several measures have been obtained from 210 leaves of each of the following species Arbutus unedoL, Pistacia lentiscus L, Myrtus communis L., Cistus ladanijer L., and Cistus albidus L. From these measures the leaf area has been determined by three different procedures: firstly, by the application of the formula S= K x length x width; secondly, by studying the simple correlation with only one independent variable, and, finally, by the study of multiple correlation. The introduction of a specific coefficient (KJ as an additional independent variable has been observed to improve the correlation coefficient more than any other independent variable. On the other hand, in spite of improving the fitting, multiple regression equations do not seem suitable for the determination of the leaf areaDownloads
