Abstract
Pepperis a fruit of the genus Capsicum, widely used in cooking as a seasoning. The objective of this study was to evaluate the effect of priming in Capsicum frutescens seeds, and on the seedlings obtained from seeds conditioned. The experimental design was completely randomized in a factorial scheme 2x6, referred to as: seed quality (above and below vigor) and five agents in priming (water, potassium nitrate at 0.2%, calcium nitrate at 0.2%, gibberellin GA3 at 200 ppm and antioxidant riboflavin at 25 ppm), and the control; with four replications. To obtain of seeds with smaller vigor minus the deterioration was performed at 42 °C for 24 hours. The employee priming method was to hydration between roles, by 20 hours at 25 ° C period. Germination and seed vigor were evaluated, as well as the emergence and seedling quality. Seeds with above vigor have better expression of the physiological potential in relation to the below vigor. The priming presented higher emergence rate. Primed seeds produced seedlings with higher dry matter.
