Optimizing Banana Barangan Micropropagation (Musa acuminata L.) with Kinetin and NAA in Vitro

Introduction

Micropropagation is a crucial biotechnology technique that enables the efficient and rapid multiplication of plants. This method has gained significant attention in recent years due to its potential to increase crop yields and improve plant quality. The banana barangan (Musa acuminata L.) is a popular fruit crop that is widely cultivated in tropical regions. However, its micropropagation remains a challenging task, requiring optimal conditions and precise control over various factors. This study aims to investigate the effect of kinetin and naphthaleneacetic acid (NAA) on banana barangan micropropagation in vitro.

Background

Micropropagation involves the use of plant tissue culture to produce large numbers of plants from a single explant. This technique has been successfully applied to various plant species, including bananas. However, the process of micropropagation is complex and influenced by several factors, including the type of plant hormones used, the concentration of these hormones, and the environmental conditions. Kinetin and NAA are two plant hormones that play crucial roles in plant growth and development. Kinetin, a cytokinin, promotes cell division and shoot formation, while NAA, an auxin, stimulates root growth.

Materials and Methods

This study was conducted at the Alifa Agricultural Research Center (Alifa-Arc) in Medan, Indonesia, from April to September 2022. The experimental design used was a complete random design of two factors: kinetin concentration (K) and NAA concentration (N). The four levels of kinetin concentration used were K0 (0 mg/l), K1 (3 mg/l), K2 (5 mg/l), and K3 (7 mg/l), while the four levels of NAA concentration used were N0 (0 mg/L), N1 (1 mg/L), N2 (1.5 mg/L), and N3 (2 mg/l). The parameters measured included the percentage of live explants, roots, number of shoots, number of leaves, and the number of roots.

Results

The results of this study showed that the combination of kinetin and NAA significantly affected the number of shoots and the number of leaves produced. However, this influence was not observed in the amount of roots formed. This suggests that although the two hormones play a role in promoting the growth of vegetative parts such as shoots and leaves, the mechanism underlying root formation may be more complex or require different conditions.

Analysis and Explanation

Kinetin and NAA are plant hormones that are often used in tissue culture to stimulate plant growth and development. Kinetin, which is included in the cytokinin group, has an important role in promoting cell division and shoot formation. Meanwhile, NAA, which is a type of auxin, functions in stimulating roots. In this study, variations in the concentration of kinetin and NAA gave insight into hormone interactions that affect the growth of banana barangan. An increase in the number of buds and leaves significantly in certain combinations shows that both work synergistically to encourage plant vegetative growth. However, success in increasing the amount of roots can be caused by the concentration of hormones that are not optimal or environmental conditions that are less supportive during the micropropagation process.

Discussion

This finding is very relevant for the practice of banana cultivation, especially in mass quality crop production. Micropropagation allows farmers to get banana seeds that are free from disease and with superior characteristics. However, to achieve a higher level of success in the formation of roots, further research may be needed to determine the most appropriate media composition and other culture parameters.

Conclusion

This research makes an important contribution to the understanding of banana micropropagation techniques and can be the basis for further research and development in the fields of agronomy and agricultural biotechnology. The results of this study provide valuable insights into the effects of kinetin and NAA on banana barangan micropropagation in vitro and highlight the need for further research to optimize the micropropagation process.

Future Directions

Future research should focus on determining the optimal concentration of kinetin and NAA for banana barangan micropropagation. Additionally, the effects of other plant hormones and environmental factors on micropropagation should be investigated. The development of new media compositions and culture parameters that can improve the success rate of micropropagation is also essential.
