MORPHOLOGY, BIOMETRICS AND GERMINATIVE POTENTIAL OF Mollinedia clavigera Tul.

Abstract

This study aimed to evaluate the morphology and biometry of fruits and seeds, as well as germination potential of Mollinedia clavigera Tul. seeds, of the family Monimiaceae, an endemic species from Brazil. The internal and external structures have been identified for the evaluation of morphology. For biometric characteristics of fruits and seeds, we considered the diameter and length, plus the weight and number of seeds per kilogram. Germination was evaluated under the temperature conditions of 20, 25 and 30ºC in two substrates (paper and vermiculite). As a morphological result, we identified common features to the Monimiaceae family, as well as the presence of Curculionidae larvae in the seeds. Biometric data showed mean values of 7,42 mm in length and 6,13 mm in diameter of fruits, 6,91 mm in length and 5,07 mm in diameter of seeds. Results have identified the temperatures of 20 and 25º C better for germination, wich happend 23 days after experiment beginning.
