This study aimed to evaluate the effects of different smoke solution doses (0%, 0.1%, 0.5%, and 1%) derived from hazelnut husk on the germination performance and oxidative stress response of two radish (Raphanus sativus L.) cultivars under salinity stress (150 mM NaCl). Morphological parameters (root and shoot length, fresh weight, germination percentage, and vigor index) and malondialdehyde (MDA) levels were assessed. The results showed that salt stress markedly increased MDA content, indicating enhanced oxidative damage in both cultivars. However, low smoke solution doses, particularly in the 2nd trial 0.1%, alleviated oxidative stress and improved germination traits in Ateş, while the 0.5% dose promoted root growth and vigor in Akkaya. The findings indicated that salinity stress increased MDA content, reflecting oxidative damage, and negatively affected germination in radish, with cultivar-specific responses. Moreover, smoke solution treatments exhibited dose- and cultivar-dependent effects, some of which may enhance germination performance, while others may induce inhibitory responses in certain physiological parameters.
