Resumo: | The harvesting is one of the most critical phases in castor bean seed production system, once physiological quality of the seeds produced in the different types of racemes in the plant can be affected. The aim of this study was assessing physiological quality of castor bean seeds in function of position of the racemes on plant. Castor bean seeds, cv. IAC-226, harvested separately at distinct periods from primary, secondary, and tertiary racemes, or of mixture of seeds originating from the different types of racemes were used. Soon after harvest, the following determinations were performed: moisture content; 1,000 seeds weight; germination; first count of germination; seedling emergence; emergence speed index; and length and dry matter of seedlings. A completely randomized experimental design was used with four repetitions. Data were subjected to ANOVA and means were compared by Tukey test, at 5% probability. The seeds from primary racemes present higher weight and vigor as compared to seeds produced on other types of racemes. Seeds originating from secondary and tertiary racemes present post-harvest dormancy, being this event more evident on seeds originating from tertiary racemes. |

Soon after harvest, the following determinations were performed: moisture content; 1,000 seeds weight; germination; first count of germination; seedling emergence; emergence speed index; and length and dry matter of seedlings. A completely randomized experimental design was used with four repetitions. Data were subjected to ANOVA and means were compared by Tukey test, at 5% probability. The seeds from primary racemes present higher weight and vigor as compared to seeds produced on other types of racemes. Seeds originating from secondary and tertiary racemes present post-harvest dormancy, being this event more evident on seeds originating from tertiary racemes. |
