Abstract

Shallots are one of the vegetable commodities that are in demand by the public, but their production does not meet market demand. One of the reasons is the difficulty of suitable seeds for the area. This condition can be overcome by obtaining superior seeds in the Samosir area through irradiation on shallot bulbs. The research objectives were to produce high production, and to identify changes in the morphological and physiological characters of the local Samosir variety shallots. Treatments were arranged in a non-factorial Randomized Block Design. Shallots bulbs were irradiated with several doses of gamma-ray irradiation (0, 1, and 2Gy) using a Co 60irradiation sources. The results showed that there were morphological and physiological differences between the irradiation treatments. The number of leaves with the highest value at 2 Gy 20.147 g and the lowest at 18.894 g control. The heaviest wet weight in the control was 20.355 g and the lowest was at 2 Gy 18.45 g. At 1 Gy and 2 Gy can significantly increase the content of chlorophyll-a 2 Gy 2.484, chlorophyll-b 2 Gy 1.579, and total chlorophyll-(a+b) 2 Gy 4.056. This proves that the dose of gamma-ray radiation affects the morphological and physiological characters of shallots.
