Evaluación de los parámetros morfofisiológicos de crecimiento del area foliar y diametros del fruto en 13 árboles de ciruelo ([Prunus salicina (Lindl.)] cv. Horvin, en el municipio de Pamplona.

Abstract

Leaf área is a widely used parameter in studies of crop ecophysiology, because the relationship between leaf area and fruit production is quite close. For its determination, the non-destructive method was used. The estimation of the leaf area is an important biometric observation that must be made in order to compare the behavior of the plants. The main objective of the research was to evaluate the morphophysiological parameters of growth of the leaf area and the diameters of the fruit of 13 plum trees (P. salicina) cv. Horvin, in the Cariongo Occidental village of the Pamplona municipality. Where it is located at 2,525 meters above sea level. The study began 30 days after defoliation, determining blade width (cm), blade length (cm), blade width by length (cm2), petiole length (cm), leaf length (cm), petiole diameter (mm), fresh weight of blade (g), fresh weight of petiole (g), fresh weight of leaf (g), dry weight of blade (g), length / width of blade, length of petiole / length of blade, leaf area of the blade (cm2), the silhouette that is 2/3 of the length by width of the blade (cm2) and the estimate of the blade, where 13 trees were selected and 3 leaves and 3 fruits were marked per tree to which Samples were carried out every 8 days at 1 PM. In itself, observational study models were found with a repeated measures design, the máximum relative content of chlorophyll was during leaf growth, it was obtained at 94 days after defoliation and indicates a high photosynthetic activity. The relationship between the leaf area and the length by the width of the leaf is linear and direct, which indicates that the leaf was growing after defoliation.
