Utilization of Arbuscular Mycorrhizal Fungi for the Efficiency Development of Lead (Pb) Metal Absorption and Growth of Hanjuang Plants (Cordyline fruticosa)

Abstract

Contamination of Pb metal into the soil is an environmental problem that has a serious impact on living things, so it needs to be addressed through phytoremediation, one of which is using hanjuang plants. Plant roots in symbiosis with arbuscular mycorrhizal fungi (AMF) can increase plant growth and the phytoremediation ability of plants growing in polluted soil. This research aims to determine the effect of AMF application on the growth of hanjuang plants and the ability of hanjuang roots to absorb Pb metal. The research design used a single treatment with a Completely Randomized Block Design (CRBD) of 4 doses of AMF with 6 replications, namely control; 10 g polybag-1; 20 g polybag-1; and 30 g polybag-1. Planting was carried out for 8 weeks to see the growth and planting of hanjuang and the efficiency of Pb absorption in plant roots. The results showed that AMF had a significant effect on plant height aged 5 to 8 weeks, plant biomass, root wet weight, and root dry weight, but had no significant effect on the efficiency of Pb absorption in the roots of hanjuang plants. An AMF dose of 30 g polybag-1 provides the best results for the growth of hanjuang plants.
