Effect Of Ascorbic Acid To Reduce Dry Dry Tapping Grooves Of Rubber Plants (heveabrasiliensis Muell. Arg) In Clones Pb 260 And IIIR 42
Introduction
The rubber plant, Hevea brasiliensis Muell. Arg, is a vital crop for many countries, particularly in Southeast Asia, where it is a major source of income for millions of farmers. However, the cultivation of rubber plants is often plagued by problems such as dry tapping grooves, which can lead to reduced latex productivity and plant health. One potential solution to this problem is the use of ascorbic acid, a natural antioxidant that has been shown to have beneficial effects on plant growth and development.
This study aims to explore the impact of ascorbic acid in reducing the dry tapping grooves on rubber plants with PB 260 and IRR clones 42. The research was conducted in experimental gardens, physiological research laboratories, and the Rubber Research Center in Galang, Deli Serdang, North Sumatra from May to October 2015.
Materials and Methods
The study used two rubber plant clones, PB 260 and IRR 42, which were selected for their high latex productivity and resistance to disease. The plants were grown in experimental gardens and subjected to a treatment of ascorbic acid, which was administered through a foliar spray. The observed variables included levels of sucrose, inorganic phosphate, thiol, superoxide dismutase (SOD), latex productivity, and blockage index.
Results
The results of the study showed that the two rubber plant clones, PB 260 and IRR 42, had significant differences in latex production. Although the administration of ascorbic acid did not show a significant difference to the Thiol, sucrose, and inorganic phosphate variables, the interaction between clone treatment and ascorbic acid gave significantly different results to the production of observed variables.
Discussion
Ascorbic acid, or better known as vitamin C, has an important role in various biochemical processes in plants. In the context of this study, ascorbic acid is thought to function as an antioxidant that helps reduce oxidative stress in plants, especially when repeated tapbles occur. Oxidative stress can trigger cell damage, thus affecting the health and productivity of rubber plants.
Although the results showed that the administration of ascorbic acid did not have a significant effect on the levels of thiol, sucrose, and inorganic phosphate, the interaction between the rubber plant clones and ascorbic acid levels showed the importance of the appropriate clone selection in maximizing latex production. PB 260 and IRR 42 clones have a different response to the treatment of ascorbic acid, which may be caused by genetic and physiological differences between the two clones.
Different latex productivity between the two clones also highlights the importance of deeper understanding of the characteristics of each clone. Pb 260 clone, which is superior in terms of productivity, may have a better physiological adaptation to local environmental conditions compared to IRR 42. Further research can be directed to investigate the mechanism behind this difference and find ways to increase the effectiveness of ascorbic acid in improving health and productivity of rubber plants.
Conclusion
In conclusion, although ascorbic acid does not show a significant impact on some of the observed variables, its interactions with rubber plant clones provide important insights that can be used to develop better management strategies in the cultivation of rubber plants. The selection of proper clones and the use of appropriate additives can help improve the yield of latex and overall plant health.
Recommendations
Based on the findings of this study, the following recommendations can be made:
- The use of ascorbic acid as a foliar spray can be a useful tool in reducing oxidative stress and improving latex productivity in rubber plants.
- The selection of proper clones is crucial in maximizing latex production, and further research should be directed to investigate the characteristics of each clone.
- The use of ascorbic acid in combination with other additives, such as fertilizers and pesticides, may be beneficial in improving plant health and productivity.
Future Research Directions
Future research should focus on investigating the mechanism behind the different responses of PB 260 and IRR 42 clones to ascorbic acid treatment. Additionally, further studies should be conducted to explore the potential benefits of using ascorbic acid in combination with other additives to improve plant health and productivity.
Limitations of the Study
This study has several limitations that should be acknowledged. Firstly, the study was conducted in a controlled environment, and the results may not be generalizable to other conditions. Secondly, the study only investigated the effects of ascorbic acid on two rubber plant clones, and further research should be conducted to explore the effects on other clones.
Conclusion
In conclusion, this study provides valuable insights into the effects of ascorbic acid on rubber plant clones. The findings suggest that ascorbic acid can be a useful tool in reducing oxidative stress and improving latex productivity in rubber plants. However, further research is needed to fully understand the mechanisms behind the different responses of PB 260 and IRR 42 clones to ascorbic acid treatment.
