ALVAREZ FONSECA, Alexander et al. Effect of seed  treatment  low doses of X-rays in peppers plants (Capsicum annuum L.).      . Nucleus [online]. 2013, n.53, pp. 14-18. ISSN 0864-084X.

The influence of seed treatment with X-rays radiation on some growth and yield of peppers plants, California Wonder variety was studied. The seeds were irradiated with X- rays irradiation source of low potency (11,47Gy/min), with doses of 5, 10, 20 y 30 Gy, using untreated seeds as controls. The plant height (mm), root length (mm), stem diameter (mm), polar average diameter (mm) ecuatorial mean diameter (mm), mean fruit mass (g) and yield per plant (kg.plant-1) were evaluated. The results showed a significant improvement (p≤0.001) in the indicators of plants height (15%), root length (12%), stem diameter (7%), equatorial mean diameter (47%), mean fruit mass (16%) and yield per plant (107%), compared to control.
