The Influence of Arbuscular Mycorrhiza on the Growth and Absorption of Pb and CD of Mucuna Pruriens Plants in Soils Contaminated with Heavy Metals

Introduction

Heavy metal pollution has become a significant environmental concern worldwide, affecting soil quality and plant growth. Arbuscular mycorrhiza (MA) is a fungus that collaborates with plant roots to increase nutritional absorption and plant tolerance to adverse environmental conditions, including soil contaminated with heavy metals. This study aims to evaluate how arbuscular mycorrhiza affects the growth of Mucuna Pruriens plants and its ability to absorb lead metal (Pb) and cadmium (CD) from polluted soils.

Background

Heavy metals such as Pb and CD can result in a decrease in soil quality and become toxic to plants. Both of these metals cannot be decomposed naturally and tend to accumulate in plant tissue, which can damage plant growth and productivity. Therefore, the use of arbuscular mycorrhiza as a phytoremediation agent is very important in tackling heavy metal pollution in the soil.

Mucuna Pruriens is a plant species known for its ability to absorb heavy metals from contaminated soils. The use of arbuscular mycorrhiza as a phytoremediation agent can enhance the plant's ability to absorb heavy metals, making it a potential solution for contaminated land rehabilitation efforts.

Methodology

This study was conducted in the Glasshouse of the Faculty of Agriculture, University of North Sumatra, Medan, using a random design of factorial groups involving two factors, namely the treatment of arbuscular mycorrhizae and heavy metal content in the soil. The first factor was the treatment of arbuscular mycorrhizae, which consisted of two groups: plants inoculated with arbuscular mycorrhizae and unocuated plants. The second factor is the treatment of heavy metals, which include six variations: without heavy metals, as well as the addition of Pb heavy metals at 400 ppm, 600 ppm, and 800 ppm, as well as a combination of Pb and CD (400 ppm Pb + 70 ppm CD and 600 ppm Pb + 105 ppm CD).

Plants were harvested after 4 months of planting to evaluate their growth and absorption of heavy metals.

Results

The results showed that arbuscular mycorrhizal inoculation significantly increased the growth and absorption of Pb and CD metals in the Mucuna Pruriens plant. Heavy metal treatment generally inhibits plant growth, with the lowest growth recorded in the treatment of 600 ppm Pb + 105 ppm CD. The highest absorption of Pb metal can be seen in the combination of arbuscular mycorrhizal treatment and 800 ppm Pb, while the highest CD absorption occurs in arbuscular mycorrhizal treatment given with 600 ppm Pb + 105 ppm CD.

Discussion

Arbuscular mycorrhiza plays an important role in increasing plant tolerance of stress conditions due to heavy metal pollution. Through its collaboration with plant roots, mycorrhizae increase the root surface area, which facilitates the absorption of nutrients and nutrients. This is very useful in contaminated soil conditions, where the available nutrients may be limited due to heavy metals.

Pb and CD metal absorption that is higher in mucuna pruriens plants inoculated with arbuscular mycorrhizae shows that the fungus can help in heavy metal bioaccumulation by changing the bioavailability of the metal in the soil. In this way, arbuscular mycorrhiza not only improves plant growth, but also has the potential to be used as a strategy for environmental remediation.

Conclusion

The application of arbuscular mycorrhiza not only provides a solution to the problem of heavy metal pollution, but also increases agricultural productivity on a sustainable manner. This effort is becoming increasingly relevant in this modern era, where environmental pollution is one of the main challenges that must be faced by agricultural and environmental sectors.

Future Directions

Further research is needed to explore the potential of arbuscular mycorrhiza in contaminated land rehabilitation efforts. The use of arbuscular mycorrhiza as a phytoremediation agent can be an alternative to traditional methods of soil remediation, which can be costly and time-consuming.
