Abstract

 

The pericarp present in some seeds can cause high lack of germination uniformity or even no germination. Thereby, the objective of this study was to evaluate the imbibition and germination percentage of C. abyssinica seeds. The experiment took place in the Federal Institute of Education, Science, and Technology of Goiás State, Morrinhos Campus, Brazil (17°48’27,59”S, 49°12’23,87”W, altitude 770 m). Imbibition and germination percentage of C. abyssinica, MS Brilhante cultivar, with and without pericarp, were evaluated. To verify the imbibition percentage, a completely randomized experimental design in factorial scheme of 5x2 was used, with five seed weighing periods (2, 4, 6, 8, and 10 hours of soaking) and two types of seeds (with or without pericarp), with four replications. To determine germination percentage, two lots of seeds, with and without pericarp, with 50 seeds each, were selected. Seeds were packed in paper towel sheets and received an average of 0,02 L of water. It was concluded that, although the pericarp of C. abyssinica seeds is permeable to water, its withdrawal doubles the germination percentage, if compared to seeds with pericarp.
