The Effect of Age of Cacao Seeds (Theobroma Cacao L.) and the Length of Storage in the Polyethylene Glycol (PEG) Medium at a Temperature of 24°C Against the Germination Power

Introduction

Cacao (Theobroma Cacao L.) is one of the 22 species in the genus Theobroma, which is included in the Sterculiaceae family in the Malvales Order. Cacao plants come from tropical forests in Central America, where the seeds have long been used as material for making drinks by indigenous tribes such as the Mayans and Aztecs. At present, cacao beans are not only used for drinks, but are also used in various products such as butter, soap, perfume, and medicines. The germination of cacao seeds is a critical process that affects the quality and productivity of cacao agricultural products. In this article, we will discuss the effect of the age of cacao seeds and the length of storage in the Polyethylene Glycol (PEG) medium at a temperature of 24°C on the germination power.

Analysis of the Age of Maturity and Length of Storage

One important aspect that affects the germination of cacao seeds is the age of maturity. Mature seeds have better germination potential compared to seeds that have not been fully ripe. The optimal maturity process helps in developing a healthy and nutrient-rich embryo, which is very important for the initial growth of plants. Research has shown that the age of maturity is a critical factor in determining the germination potential of cacao seeds. Seeds that are harvested at the optimal maturity stage tend to have higher germination rates compared to seeds that are harvested at an earlier or later stage.

In addition to the age of maturity, the length of storage also has a significant effect on germination. Cacao seeds stored in the Polyethylene Glycol (PEG) medium at a temperature of 24°C showed changes in the characteristics of germination with increasing storage time. PEG is often used in agronomic research because of its ability to maintain humidity and reduce water stress that can affect seeds. The use of PEG as a storage medium has been shown to improve the germination of cacao seeds by maintaining the optimal moisture levels and reducing the risk of water stress.

Physiological Processes Affecting Germination

Over time, the stored cacao seeds can experience a decrease in germination due to the physiological processes that occur. This includes a decrease in seed viability, which can be triggered by factors such as decreased seed quality, physical damage, or pests and diseases. The decrease in seed viability can be attributed to the loss of water content, which can lead to the degradation of the embryo and the reduction of germination potential. Therefore, it is essential to pay attention to the duration of storage and storage conditions so that cacao seeds still have optimal germination.

Recommendations for Cocoa Planting

To get maximum results in planting cacao, it is recommended that farmers and cultivators pay attention to the age of seeds and storage methods. Using a perfectly cooked seed and avoiding storage for a long time without the right treatment is the key to increasing the possibility of the success of germination. Optimizing storage conditions, such as maintaining appropriate temperature and humidity, and using effective storage mediums such as PEG, can help maintain seed quality and improve germination.

Conclusion

In conclusion, the age of cacao seeds and the length of storage in the Polyethylene Glycol (PEG) medium at a temperature of 24°C have a significant effect on the germination power. The optimal maturity process and the use of PEG as a storage medium can help improve the germination of cacao seeds. By paying attention to the duration of storage and storage conditions, farmers and cultivators can increase the productivity and quality of cacao agricultural products. This will certainly support the growth of the sustainable cacao industry and provide significant economic benefits for farmers.

Future Research Directions

Future research should focus on the development of new storage methods and technologies that can improve the germination of cacao seeds. This can include the use of advanced storage mediums, such as hydrogels or superabsorbent polymers, that can maintain optimal moisture levels and reduce the risk of water stress. Additionally, research should focus on the development of new cultivars that are resistant to pests and diseases and have improved germination potential.
