Abstract: Alternative use of the X-ray test to evaluate seed quality has become increasingly diverse. This study was performed primarily to establish experimental procedures and verify the effectiveness of the X-ray test to detect damage or abnormalities in bell pepper (Capsicum annuum) seed structure associated with germination. Five seed lots each of hybrids Reinger and Sentinel were used. Two hundred seeds per lot were exposed to durations and intensities of X-radiation and visually classified into four categories ac… Show more

“…In Figures 3B and 3C, dark areas caused by deterioration of the radicle extremity ( Figure 3B) and the cotyledon ( Figure 3C) can be seen, and this adversely affected the germination, resulting in seedlings with a root abnormality ( Figure 3B') and an abnormal seedling ( Figure 3C'). Similar results are described for the seeds of Lithraea molleoides (Machado and Cicero, 2003) and bell pepper (Gagliardi and Marcos-Filho, 2011). From the results shown in Table 2, relating seed morphology to the results of the germination test, a small difference in the germination of seeds from the different morphological categories could be seen, when only seeds from lot 1 with lot larger area of endosperm and embryo produced a higher percentage of normal seedlings.…”

“…Therefore, for this reason, the physiological potential was responsible for their germination performance, considering that seeds with a greater filled area (category 3) gave rise to both normal and abnormal seedlings (Figure 4). Similar results were observed by Gagliardi and Marcos-Filho (2011) for bell pepper seeds, when even the undamaged seeds in some lots with an internal area completely filled by the embryo and endosperm gave rise to abnormal seedlings and non-germinated seeds. and 2, those with a smaller area occupied by embryonic seed tissues; therefore, in most cases, the physiological potential was responsible for this result and not the seed morphology.…”
