Arbuscular mycorrhizal fungi are a form of symbiosis between fungi and plant roots. According to previous research, it is stated that almost all plants can have symbiosis with mycorrhizae. One indicator of the symbiosis that occurs between fungi and plant roots is by looking at the percentage of arbuscular mycorrhizal fungi infection on plant roots. This study aims to determine the percentage of root colonization of tertumum plants infected by arbuscular mycorrhizal fungi. The research method used is to take the root chili sauce of tertum plants. Samples of teruntum plant roots were cleaned and soaked in 2% HCl. Subsequently, it was cleaned and stained with trypan blue solution. The stained roots were then cut into pieces with a size of 1 cm and arranged on a glass object and observed under a microscope. Based on the observations made, the results of the calculation of the percentage of root colonization in Teruntum plants were 28%. If it is converted into the criteria table for the percentage of root colonization, it is classified into the low category. © 2022 American Institute of Physics Inc.. All rights reserved.
