To determine the relationship between percentage of germination and seedling emergence in sunflower seeds, achenes were irradiated at doses of 0, 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000 Gy, to establish an estimation model between both variables. Main objective was, to compare the homogeneity of slopes between germination and sprouting, of sunflower achenes irradiated with 60Co gamma rays. Regression models for both cases were determined by the least squares method. Slopes in question were analyzed using the tcal test for homogeneous variances. Results indicated that there is a high correlation between the slope of germination and seedling emergence curves, these being homogeneous. From this investigation it can be concluded that both slopes are homogeneous, therefore, the percentage of seedling emergence can be an estimator of the percentage of germination in achenes of sunflower, when they are irradiated with gamma of 60Co. | Slopes comparison of: Germination and seedling emergence curves VS60CO gamma radiation dose sunflower achenes
