Abstract

Calotropis procera, known as “flor de seda” or “algodão de seda”, is specie of great potential of dry matter production and high nutritions value, becoming food source for herd cattle in Paraíba at the time of scarcity. The objective of this work was to study the biometrics characteristics of fruits and seeds of Calotropis procera in Patos (PB) region from the period of May to July of 2004. Mature fruits of single plants of 2,66 m on average height were collected, and its length, circunference and weight were appraised. At the same time, the number of seeds in each fruit was quantified and the weight of 1000 seeds was obtained. The diameter of fruits varied from 28 to 78 mm while the circunference varied from 18 to 28 mm. The weight of fruits varied from 15 to 39 g while the average weight of seeds was 0,003 g. As a whole, 77,42% of fruits presented from 300 to 400 seeds. The data showed that the biometrics characteristics of fruits of Calotropis procera present a large varaiability and the elevated number of seeds in fruits is propitious to its dissemination.
