Abstract: This study was carried out to investigate the response of dill plants to gamma radiation and bio-fertilizers on the essential oils and their constituents during vegetative, flowering and fruiting stages. The results showed that the most effective treatment on the volatile oil content in the three stages was 2 k-rad + bio-fertilizers. The major compounds were found to be α-phellandrene, limonene, β-phellandrene and p-cymene (vegetative stage). In the flowering stage, p-cymene, carvone, dillether and dillapiole. Whereas, carvone, dillapiole and limonene were major compounds (fruiting stage). The results showed those dill volatile oils at different developing stages exhibited strong and a variable degree of antimicrobial activity.
