Rose tomatoes, scientifically known as Solanum lycopersicum var. Roses are a type of tomato characterized by its small, vibrant red fruits. Gamma rays, a form of electromagnetic radiation with a very short wavelength and high energy, can cause plant mutations, leading to genetic variations that could potentially enhance the quality and quantity of crops. This study aimed to investigate the impact of gamma-ray irradiation on the growth of rose tomatoes. The research was conducted at the Irradiation and Instrumentation Laboratory on Jalan Lebak Bulus Raya, Jakarta, and the Green House of Labuhanbatu University, Rantauprapat City, Labuhanbatu Regency, North Sumatra Province. The experiment took place from December 2023 to March 2024. utilizing a single factor Completely Randomized Design with 4 levels and 5 replications, precisely gamma-ray radiation doses of 0 Gy, 100 Gy, 200 Gy, and 300 Gy. The findings revealed that the highest germination parameters were observed at a dose of 300 Gy, while the control treatment exhibited the lowest germination. However, the gamma irradiation treatment did not significantly impact plant height and the number of leaves.
