Introduction

Cayenne pepper (Capsicum frutescens L.) is a widely cultivated crop in Indonesia, known for its spicy flavor and medicinal properties. However, drought stress is a significant threat to cayenne pepper production, leading to reduced yields and lower quality crops. In recent years, researchers have been exploring various methods to improve plant resistance to drought stress, including the application of biogenic organic compounds such as putresin. This article discusses the application of putresin on various varieties of cayenne pepper under in vitro conditions, highlighting its potential as a drought stress management tool.

Background

Putresin is a biogenic organic compound that has been shown to have a positive impact on plant growth and resistance to environmental stress. Research has demonstrated that putresin can increase plant tolerance to drought, salinity, and other abiotic stressors. In the context of cayenne pepper production, putresin has been identified as a potential tool for improving plant resistance to drought stress. However, the effectiveness of putresin on different varieties of cayenne pepper is not well understood.

Methodology

This study was conducted at the Network Culture Laboratory, Alifa Agriculture Research Center (Alifa-ARC) in Medan, Indonesia, from September to December 2020. The experimental design used was a random design complete with two factors: the variety of cayenne pepper (Sigantung, Wijaya, Bara, Genie, and Hanna 08) and the concentration of putresin applied (0 ppm, 10 ppm, 15 ppm, and 20 ppm). Each treatment was repeated five times to ensure the accuracy of the results. The observed parameters included the percentage of living planlets, visualization of planlets (consisting of the percentage of green planlet, brownish green, and brownish), plant height, number of leaves, number of roots, root length, wet weight, and dry weight.

Results

The results of this study showed that the treatment of cayenne pepper varieties had a significant effect on all parameters except visualization of brownish green planlets. Varieties of Sigantung, Wijaya, Bara, Genie, and Hanna 08 showed variations in the ability to survive and grow under drought stress conditions, as well as a response to putresin. The concentration of putresin also had a significant impact on almost all observed parameters, indicating that the application of putresin can increase plant resistance to environmental stress.

Discussion

The interaction between the treatment of varieties and the concentration of putresin significantly affected the height of the plant, number of leaves, and the number of roots. This shows that a certain combination between varieties and concentrations of putresin can be more effective in increasing plant growth and resistance in drought stress conditions. The results of this study provide valuable insights into the potential use of putresin to increase plant durability, especially cayenne pepper, which is an important commodity in Indonesia.

Conclusion

This study demonstrates the potential of putresin as a biogenic organic compound for improving plant resistance to drought stress in cayenne pepper. The results of this study provide valuable insights into the potential use of putresin to increase plant durability, especially cayenne pepper, which is an important commodity in Indonesia. Management of drought stress is very important considering climate change that causes extreme rainfall fluctuations. By knowing the variety of chili that is more responsive to putresin, farmers can choose the appropriate varieties to be planted in areas with high drought risk.

Recommendations

This study opens space for further research on the mechanism behind the action of putresin in plants and its effectiveness in more varied concentrations or under other environmental stress conditions. By understanding and utilizing plant responses to putresin, we can be wiser in developing agricultural strategies that are sustainable and environmentally friendly. Overall, this research not only contributes to the field of agriculture but also provides innovative solutions to face the increasingly common challenges of drought, especially in agrarian countries such as Indonesia.

Future Directions

Future research should focus on the following areas:

Mechanism of action: Understanding the mechanism behind the action of putresin in plants will provide valuable insights into its potential use as a drought stress management tool.
Variety selection: Identifying the most responsive varieties of cayenne pepper to putresin will enable farmers to choose the most suitable varieties for planting in areas with high drought risk.
Concentration optimization: Optimizing the concentration of putresin for different varieties of cayenne pepper will improve its effectiveness as a drought stress management tool.
Environmental stress conditions: Investigating the effectiveness of putresin under other environmental stress conditions, such as salinity and temperature stress, will provide a more comprehensive understanding of its potential use as a drought stress management tool.

Conclusion

In conclusion, this study demonstrates the potential of putresin as a biogenic organic compound for improving plant resistance to drought stress in cayenne pepper. The results of this study provide valuable insights into the potential use of putresin to increase plant durability, especially cayenne pepper, which is an important commodity in Indonesia. Management of drought stress is very important considering climate change that causes extreme rainfall fluctuations. By knowing the variety of chili that is more responsive to putresin, farmers can choose the appropriate varieties to be planted in areas with high drought risk.
