Análise do desempenho fisiológico das famílias F3 de Ricinus communis, L. quanto ao caráter quantidade de óleo nas sementes

Abstract

Castor bean (Ricinus communis L.) is an oilseed crop that has a big economic and social importance to the Northeast region; its main product is the oil. The seed of the castor beans have an oil amount which ranges from 35% to 55%, with a commercial standard of 44%. This report aimed to relate the results of the oil extraction from the seeds of the F3 families of Ricinus communis L. which are produced from the intersection of the BRS-149 Northeast and Sipeal 28 for purposes of quantification. The total oil amount in the seeds that were tested, was determined by gravimetry, by using the organic solvent hexane at room temperature. The analysis of the results was made using the analysis of variance. They were compared by Scott Knot test, aiming to the selection of promising genotypes. The analysis shows that there was statistics significant differences among the families F3 1% of probability for the sign total lipids amount in the seed. The total lipids content ranged between 27 and 46% in the families studied. The families 21 and 23 stuck out with lipids content of 42 to 46%, respectively.
