Highest germinability, mean germination time, mean daily germination, vigour index and growth rate were observed in untreated seeds, however these traits were relatively less affected at lower irradiation level (up to 200 Gy). An irradiation level of ≥ 400 Gy severely affected germination traits and seedling growth and consequently 441 Gy irradiation level was considered as the lethal dose (LD<jats:sub>50</jats:sub>) for dragon fruit. Photosynthetic pigments, protein content and nutrient content were highest in untreated seedlings and moderately high up to 200 Gy. Findings demonstrated that the concentration of biochemical markers for abiotic stress tolerance viz. proline, phenol, flavonoid and antioxidant enzymes (superoxide dismutase, catalase and ascorbate peroxidase), were significantly high at 200 Gy irradiation level. Hence an irradiation dose of 200 Gy may be considered as an optimal for induced mutagenesis for abiotic stress tolerance in dragon fruit with the least possible unintended damage to seedling growth traits.
