Abstract: Sorghum (Sorghum bicolor (L.) Moench is a cereal crop that has great potential to be developed in Indonesia. Besides having the tolerance to various types of environmental stress, sorghum also has a variety of uses such as food material, feed and industrial materials. One stress conditions faced by the sorghum is a heavy metal pollutants, including chromium (Cr). Mycorrhizal symbiosis with the roots can improve plant resistance to heavy metal stress. The purpose of the research is to determine the treatment effect of Glomus mossae mycorrhiza on seed germination and the growth of UPCA sorghum cultivars sprouts on hexavalent Cr6+ stress condition. This research using completely randomized design method, with 2 treatments that is mycorrhizal treatment as many as 5 g/100 g planting media and without granting mycorrhiza (control), with each treatment as many as 50 repeats. Cr6+ stress is given in the form of dichromate compounds (K2Cr2O7) in the amount of 5 mg Cr6+/L. Germination was performed using sterile sand medium and watered with Hoagland nutrient solution. Seed germination is carried out for 7 days. The observed parameters include number of seeds that germinated, the length of the roots and shoots, and the seedling dry weight. The results showed a significant effect of given mycorrhizal on seed germination and the growth of UPCA sorghum cultivars sprouts on Cr stress condition. On Cr6+ stress condition, the length of the roots and shoots, and sorghum seedling dry weight that was given G. mossae showed higher results than without G. mossae. Otherwise, the percentage of sorghum seed germination inoculated with G. mossae show lower results compared with sorghum without G. mossae inoculation, on Cr6+ stress condition.
