Impacts of Gamma Irradiation Dose and Salt Stress Conditions on the Germination of Two Capsicum annuum ‘Bird’s Eye’ Varieties
Published: July 29, 2026
Abstract
This study investigated the effects of gamma irradiation dose on the germination ability of two chili pepper (Capsicum annuum ‘Bird’s Eye’) varieties, Sen Hong and Thanh Phong, under salt stress conditions.
Seeds were irradiated with six doses (0, 10, 20, 30, 40, and 50 Gy) and then germinated in NaCl solutions at six salinity levels (0, 1, 2, 3, 4, and 6‰). The germination percentage was recorded after two weeks.
The results showed that the lowest germination rate was observed at 6‰ NaCl without irradiation (0 Gy), reaching 66.7%. Germination increased significantly when seeds were irradiated at 50 Gy, reaching 93.3% for the Thanh Phong variety and 100% for the Sen Hong variety.
These findings suggest that gamma-induced mutation may be an effective approach for improving plant tolerance to abiotic stresses, such as drought and salinity.
