The Effect of Giving Coconut Water and NAA on the Growth of Cattleya Orchids in Vitro

Introduction

The cultivation of Cattleya orchids has become increasingly popular in recent years due to their unique beauty and fragrance. However, the process of cultivating these orchids can be challenging, especially when it comes to their growth and development. In vitro cultivation, which involves growing plants in a controlled laboratory environment, has become a popular method for cultivating Cattleya orchids. However, the success of in vitro cultivation depends on various factors, including the type of growth medium used and the concentration of plant growth regulators.

The Importance of Coconut Water and NAA in Plant Growth

Coconut water and NAA (naphthalene acetic acid) are two substances that have been widely used in plant growth and development. Coconut water is a natural source of nutrients and minerals that can support plant growth and development. It contains a high concentration of potassium, which is essential for plant growth and development. NAA, on the other hand, is a synthetic plant growth regulator that can stimulate root and shoot growth.

Experiment Design

This study aims to examine the effect of giving coconut water and NAA on the growth of Cattleya orchids in vitro conditions. The study was conducted at the Network Culture Laboratory, Faculty of Agriculture, University of North Sumatra, Medan. Using a Factorial Complete Random Design (RAL), this study involves two treatment factors, namely the variation of the concentration of coconut water and NAA.

Coconut water is given in four different levels: control (KO), 100 ml/L (K1), 150 ml/L (K2), and 200 ml/L (K3). Meanwhile, NAA also consists of four levels: control (N0), 0.05 ml/L (N1), 0.10 ml/L (N2), and 0.15 ml/L (N3), with six replications for each treatment. In each bottle, there is one explant and each treatment produces 96 sample plants.

Observed Parameters

The researchers observed several parameters, such as the percentage of life (%), the number of shoots, the number of roots, the length of the roots, and the increase in the number of leaves. The analysis shows that coconut water has a significant effect on the number of shoots and increase in the number of leaves, but has no significant effect on the percentage of life, the number of roots, and the length of the roots. On the other hand, NAA's treatment shows a significant effect on the number of shoots, number of roots, roots, and increase in the number of leaves, although it does not have a significant effect on the percentage of life.

Interaction between Coconut Water and NAA

The interaction between the concentration of coconut water and NAA is also examined. The results show that the interaction has a significant effect on the number of shoots and the increase in the number of leaves, but is not significant to the percentage of life, the number of roots, and the length of the roots.

Conclusion

The findings of this study provide valuable insight for the development of Cattleya orchid tissue culture. The use of coconut water as a growth medium is proven to support the process of development of shoots and leaves. Meanwhile, the addition of NAA can optimize root and shoot growth, which is very important for the success of in vitro orchid production. Researchers recommend that further development is carried out to explore a combination and more varied treatment concentration to improve results. The results of this study can be used as a reference for practitioners and researchers in the field of horticulture and plant tissue culture.

Recommendations for Future Research

Based on the findings of this study, several recommendations can be made for future research. Firstly, further studies can be conducted to explore the optimal concentration of coconut water and NAA for Cattleya orchid tissue culture. Secondly, the interaction between coconut water and NAA can be further examined to determine the optimal combination of these substances for plant growth and development. Finally, the use of coconut water and NAA in other types of plant tissue culture can be explored to determine their effectiveness in promoting plant growth and development.

Implications of the Study

The findings of this study have several implications for the development of Cattleya orchid tissue culture. Firstly, the use of coconut water as a growth medium can support the process of development of shoots and leaves. Secondly, the addition of NAA can optimize root and shoot growth, which is essential for the success of in vitro orchid production. Finally, the interaction between coconut water and NAA can be used to determine the optimal combination of these substances for plant growth and development.

Limitations of the Study

This study has several limitations that need to be addressed in future research. Firstly, the study was conducted in a controlled laboratory environment, which may not reflect the actual conditions of in vitro cultivation. Secondly, the study only examined the effect of coconut water and NAA on the growth of Cattleya orchids, and did not consider other factors that may affect plant growth and development. Finally, the study only used a limited number of treatments, which may not be representative of the actual conditions of in vitro cultivation.

Future Directions

Based on the findings of this study, several future directions can be explored. Firstly, further studies can be conducted to explore the optimal concentration of coconut water and NAA for Cattleya orchid tissue culture. Secondly, the interaction between coconut water and NAA can be further examined to determine the optimal combination of these substances for plant growth and development. Finally, the use of coconut water and NAA in other types of plant tissue culture can be explored to determine their effectiveness in promoting plant growth and development.

Conclusion

In conclusion, this study provides valuable insight for the development of Cattleya orchid tissue culture. The use of coconut water as a growth medium is proven to support the process of development of shoots and leaves. Meanwhile, the addition of NAA can optimize root and shoot growth, which is very important for the success of in vitro orchid production.
