Biometric characterization of fruit, diaspheres and seeds Syagrus coronata (Mart.) Becc / Caracterização biométrica de frutos, diásporos e sementes de Syagrus coronata (Mart.) Becc

Abstract

The species S.coronata, better known as licuri, is an ornamental palm, native to Brazil, of great economic importance because it provides raw material for production of food, leaves and stems for building houses, almond oil is extracted good quality with potential for the synthesis of biodiesel. The biometric characterization of fruits and seeds is relevant to the study in the area of breeding populations for seedling production among others. The objective was to study the genetic diversity of fruits, seeds and diaspores of S. coronata by means of biometrics. The work was performed at the Laboratory of Seed Analysis - (LAS) of the Federal Rural University of Pernambuco / Academic Unit of Garanhuns-PE, with fruit licuri collected in rural Caetés-PE. The evaluations were: number of fruits per bunch and rachilles, rachilles number per cluster, average weight of 100 fruits and diaspores, average fruit weight and diaspore and biometrics fruit, seeds and propagules. 50% of clusters of S. coronata analyzed possessed a fruit number between 304-417 and a tendency to a normal distribution. For rachilles number per bunch was found that most of rachilles were grouped into two classes at the following intervals: 35.5 to 40.40 and 40.5 to 45.5 mm corresponding to 40 and 30% of the samples, respectively. With respect to average weight of 100 fruits and diaspores was found average values of 1.056.25 g (fruits) and 472.5 g (diaspores). The characteristics evaluated showed high genetic variability within the population studied licuri
