Susila E, Elita N, Yefriwati. 2016. Examination of FMA indigenous isolates on the growth and infection of rice roots in SRI method. Pros Sem Nas Masy Biodiv Indon 2: 71-75. SRI method (The System of Rice Intensification) uses the aerobic system during the vegetative phase allowing the decomposer microorganism alive and active. The aerobic condition supports the soil microbial, therefore its diversity in the soil is abundant through the root exudate. The use of indigenous Arbuscular Mycorrhizal Fungi (AMF) is more adaptive and effective therefore can improve its ability to absorb nutrients and plant growth. This study aimed to: (i) determine the influence of indigenous AMF isolates to the growth and dry weight of rice plants, and (ii) determine the influence of indigenous AMF isolates to the roots infection of rice plants. The research was arranged by using a completely randomized design with 7 treatments, consisted of 6 treatments of indigenous AMF isolates and control with three repetitions. The results showed the highest plant height (106.0 cm) and the highest number of tillers (35.0 tillers) were obtained from the treatment of Glomus sp3 isolate. The highest plant dry weight was 34.5 g which obtained from the treatment Glomus sp3 isolate, was not different significantly with the treatment of Glomus sp2 and Sclerocystis sp. isolates. There was not the significant difference to the percentage of infection on the root from all AMF isolates, but different significantly with control. From six indigenous AMF isolates which tested, three isolates chance as inoculants to be developed on wetland intensification by using the SRI method, as gives rise to growth and the improvement of the dry weight of the rice plants, they were Glomus sp2, Glomus sp3 and Sclerocystis sp. |
