Abstract

Gamma irradiation has emerged as a promising approach to enhance yield and quality of various crops. The aim of the current work was to assess the effect of various gamma irradiation doses (0, 100, 150, 200, 250 and 300 Gy) on the vegetative growth, biochemical changes and oil yield of cumin plants during the twoconsecutive seasons of 2020/2021 and 2021/2022 at the Experimental Farm of Sakha Horticulture Research Station, Kafr El-Sheikh Governorate, Egypt in a randomized complete blocks design with three replications. The results showed that low doses of gamma irradiation significantly enhanced vegetative growth and yield characteristics, photosynthetic pigments, antioxidant activity and oil yield. On the other hand, as the applied doses increased, plant height, number of branches, dry weight, chlorophyll content and oil yield were decreased, while carotenoid and phenolic content were increased as defence mechanism against elevated irradiation doses compared to the control. The genetic advance (GA%) and the high heritability (Hb%) values indicated that the second generations may show additional advancements. Generally, gamma irradiation can be used to improvethe growth, oil yield and biochemical content of cumin at 150 Gy as a seed treatment.
