Biochemical changes in garlic (Allium sativum L.) during storage following gamma-irradiation

Author(s): Arguello, J., Orioli, G.

Abstract: The aim of this paper was to evaluate an acute dose of gamma-rays (10 Gy) on post-dormant garlic seed cloves in terms of total DNA, total RNA, total protein and soluble carbohydrates in order to correlate these levels with sprouting inhibition induced by gamma-irradiation. Decreases in total DNA content were found in inner sprouts immediately and 100 days after irradiation. The total RNA and protein contents and the carbohydrate content of the storage leaf or the inner sprout were not affected by gamma-irradiation. The results support the notion that in post-dormant garlic seed cloves, DNA content and its behaviour seem to be among the sensitive cellular responses to radiation.
