Understanding the Activity of Peroxidase Enzyme (POD) in Rubber Plants: A Physiological Analysis of Hevea Brasiliensis Muell. Arg

Introduction

The rubber plant, Hevea Brasiliensis Muell. Arg, is a vital crop for many countries, providing a significant source of income for farmers and contributing to the global economy. However, the plant is often affected by various problems, including Tapping Panel Dryness (Cash) and the fall of the leaf, which can significantly reduce the production of rubber latex and speed up the plant rejuvenation process. In this study, we aim to understand the effect of the activity of the peroxidase enzyme (POD) in the latex and the physiological analysis of rubber skin from the rubber plant Hevea Brasiliensis Muell. Arg, especially in PB 260 and Rrim clones 921.

The Importance of Peroxidase Enzyme (POD) in Rubber Plants

Peroxidase enzyme (POD) plays a crucial role in the defense mechanism of plants against various stresses, including pathogens, drought, and temperature fluctuations. In rubber plants, POD is involved in the regulation of the production of rubber latex, which is a complex mixture of polymers and other compounds. The activity of POD in rubber plants can be affected by various factors, including the type of plant, environmental conditions, and the presence of stressors.

Research Purpose and Methods

This study aims to determine the activity of peroxidase in latex and conduct an analysis of rubber skin from two plant clones, namely PB 260 and Rrim 921, with the addition of antidepressants during the fall of the leaf. The study was conducted at the Physiology Laboratory, the White Sungei Rubber Research Center, from March to June 2016. The analysis was carried out using the correlation method and the T test with the help of Minitab 16.0 and SPSS 20.0 software. The factors analyzed include clones (Rrim 921 and PB 260), types of plants (healthy and cash), and stimulant formulas.

Parameter that is Considered

The parameters observed in this study include the content of thiol, inorganic phosphate (PI), sucrose, protein, and the activity of the peroxidase enzyme (POD). The results showed that thiol values in rubber skin ranged from 0.1-0.9 mm, PI between 4-20 mm, sucrose between 24-60 mm, protein between 40-65 mg/unit, and POD activity ranged from 0.1-1 unit/mg protein. These values vary according to plant conditions and environmental factors.

Analysis of Results

From the results of the study, a positive relationship was found between Thiol and PI parameters (0.534), sucrose and protein (0.926), and sucrose with POD (0.257). However, there is also a negative relationship between Thiol and Sucrose (0.134), Thiol protein (0.160), Thiol and POD (0.615), PI and Sucrose (0.473), PI protein (0.156), and protein and POD (0.529).

Research Added Value

The results of this study provide a deeper insight about the interaction between various metabolic variables in rubber plants, especially in the context of cash and autumn leaves. Understanding the activity of the enzyme peroxidase and related parameters can be a useful tool in recovery efforts and increasing the production of rubber latex. In addition, this research can be the basis for further research on the application of antidepressants in improving the health of rubber plants and stimulating optimal growth.

Conclusion

In conclusion, this study provides valuable information about the activity of peroxidase enzyme (POD) in rubber plants and its relationship with various metabolic variables. The results of this study can be used to improve the management of rubber plants and increase the production of rubber latex. Furthermore, this research can be a guide for researchers and practitioners in the fields of agronomy and physiology of rubber plants in the future.

Recommendations

Based on the results of this study, the following recommendations are made:

Further research should be conducted to investigate the effect of antidepressants on the activity of peroxidase enzyme (POD) in rubber plants.
The use of antidepressants should be explored as a potential tool for improving the health of rubber plants and stimulating optimal growth.
The results of this study should be used to develop better practices in plant management and increase the production results of rubber farmers.

Limitations of the Study

This study has several limitations, including:

The study was conducted on a limited number of plant clones, which may not be representative of all rubber plant varieties.
The study was conducted in a controlled environment, which may not reflect the actual conditions of rubber plant cultivation.
The study did not investigate the effect of other stressors on the activity of peroxidase enzyme (POD) in rubber plants.

Future Research Directions

Future research should focus on investigating the effect of antidepressants on the activity of peroxidase enzyme (POD) in rubber plants and exploring the use of antidepressants as a potential tool for improving the health of rubber plants and stimulating optimal growth. Additionally, further research should be conducted to investigate the effect of other stressors on the activity of peroxidase enzyme (POD) in rubber plants.
