Introduction

Understanding the Impact of Drought Stress on Cayenne Pepper Varieties

Drought stress is a significant challenge in agriculture, particularly in regions with limited water resources. Climate change has exacerbated this issue, making it essential to develop strategies to mitigate its effects on crop yields. One approach is to identify and select crop varieties that are more resilient to drought stress. This study aims to explore the morphophysiological appearance of several varieties of cayenne pepper (Capsicum frutescens L.) in dealing with drought stress.

Background

Cayenne pepper is a popular spice crop that is widely cultivated in tropical regions. It is a member of the Solanaceae family and is known for its high water requirements. However, with the increasing challenges of drought stress, it is essential to develop cayenne pepper varieties that are more resistant to dry conditions. This study was conducted to investigate the morphophysiological appearance of several varieties of cayenne pepper in response to different watering patterns and to identify the most drought-tolerant varieties.

Research Methods

Experimental Design and Parameters Observed

This study used a factorial random group design with two factors: watering pattern and variety of cayenne pepper. The first factor was a watering pattern divided into three groups: watering once a day, once every three days, and once every five days. The second factor was the variety of cayenne pepper tested, namely Sigantung, Genie, Hanna 08, and Wijaya, with each variety repeated four times. The parameters observed in this study included plant height, number of leaves, root wet weight, rooted dry weight, flowering age, bearing age, fruit weight, number of branches, water content, leaf area, and chlorophyll content A, B, total chlorophyll, and Drought sensitivity index.

Experimental Location and Duration

The research took place at the Greenhouse of the Faculty of Agriculture, University of North Sumatra, Medan, from September 2019 to February 2020. The greenhouse provided a controlled environment that allowed for precise management of watering patterns and other experimental conditions.

Research Results

Effect of Watering Patterns on Morphophysiological Parameters

The results showed that the treatment of varieties had a significant effect on parameters such as plant height, number of leaves, root wet weight, root dry weight, fruit weight, number of branches, water content, leaf area, chlorophyll A, chlorophyll B, and total chlorophyll. Nevertheless, the treatment of varieties does not show a significant effect on the age of flowering and the age of fruit. On the other hand, watering patterns have proven to have a significant effect on all measured parameters.

Drought Sensitivity Index

Through the analysis of the index of drought sensitivity, the genie variety is identified as a moderate variety of drought stress, while the Sigantung, Hanna 08, and Wijaya varieties are categorized as varieties that are sensitive to dryness. This discovery is very important given the increasing challenges in agriculture due to climate change and decreased water availability.

Conclusion

Implications for Agricultural Production

From the results of this study, it can be concluded that the selection of appropriate cayenne pepper varieties, as well as managing effective watering patterns, can contribute to plant resilience to drought stress. By understanding the morphysiological varieties of different varieties, farmers and researchers can develop a better strategy to increase agricultural production in increasingly uncertain environmental conditions. This finding provides a basis for further research that can help in the development of cayenne pepper varieties that are more resistant to drought conditions.

Recommendations for Future Research

This study provides a foundation for further research on the development of drought-tolerant cayenne pepper varieties. Future studies can focus on identifying the genetic mechanisms underlying drought tolerance in cayenne pepper and developing breeding strategies to enhance drought resistance in this crop. Additionally, research can be conducted to investigate the effects of drought stress on other morphophysiological parameters, such as root growth and leaf senescence.

Limitations and Future Directions

This study has several limitations, including the use of a small number of cayenne pepper varieties and the limited duration of the experiment. Future studies can address these limitations by using a larger number of varieties and conducting longer-term experiments. Additionally, research can be conducted to investigate the effects of drought stress on other crops and to develop strategies for improving drought tolerance in these crops.

Conclusion

In conclusion, this study provides valuable insights into the morphophysiological appearance of several varieties of cayenne pepper in response to drought stress. The results of this study have significant implications for agricultural production and provide a basis for further research on the development of drought-tolerant cayenne pepper varieties.
