Effect of Epsom Salt Concentration and Time Interval Application of Growing Regulatory Substances GA3 Against Flowering of Dendrobium Sp Orchids

Introduction

Orchid cultivation is a complex process that requires careful consideration of various factors to optimize flowering results. One of the key factors that influence orchid flowering is the use of fertilizers and hormones. Epsom salt, a natural source of magnesium, is commonly used in orchid cultivation to promote healthy growth and flowering. However, the optimal concentration of Epsom salt and the frequency of application of growing regulatory substances (GRS) such as GA3 are not well understood. This study aims to investigate the effect of Epsom salt concentration and GA3 application interval on flowering of Dendrobium sp. orchids.

Materials and Methods

The study was conducted on Jalan Gajah No. 58, Medan, from February to September 2004. A factorial complete random block design was used, consisting of two factors: Epsom salt concentration and GA3 application interval. The Epsom salt concentrations used were 0 g/liter (E0), 0.25 g/liter (E1), 0.50 g/liter (E2), and 0.75 g/liter (E3). The GA3 application intervals used were once a week (G1), once two weeks (G2), and once three weeks (G3).

Results

The results of this study showed that the effect of Epsom salt concentration was only significant on the remaining number of leaves, but had no significant effect on the growth of stem length, tuber diameter, number of leaves, number of segments, flowering time, flower stem length, number of flower shoots, budget time of shoots, duration of flowering shoots, life span of flowers, and flower diameter. On the other hand, GA3 application intervals had a significant effect on the remaining number of leaves, opening time of shoots, and duration of flowering shoots. However, the effect was also insignificant on the growth of stem length, tuber diameter, number of leaves, number of segments, flowering time, flower stem length, number of flower shoots, flower stems, and flower diameter.

Discussion

The results of this study raise several interesting questions related to the management of fertilization in orchid cultivation. Although Epsom salt is known to have essential magnesium for plants, in the context of this study, the positive effect was not significant in the growth parameters and flowering of Dendrobium sp. It can be interpreted that the concentration of Epsom salt used in this study may not be enough to meet optimal nutritional needs of plants.

Conversely, GA3 application intervals show more significant effects, especially in the aspects of leaf maintenance and flowering. GA3 is a hormone that plays a role in accelerating the process of flowering and development of flower shoots. Significant results at the time of the opening of the shoots and the duration of flowering show that the use of GA3 in the right frequency can affect the quality of flowers and the duration of orchid flowers.

Conclusion

In conclusion, this study provides valuable insights in understanding the influence of nutrients and hormones on orchid flowering. By knowing the factors that influence, it is expected to increase the yield of high-quality Dendrobium SP orchids in the future. The combination of the selection of appropriate Epsom salt concentrations and GA3 application interval regulation needs to be carefully considered to optimize the flowering results. Cultivation is expected to be able to conduct further experiments with different variations of concentrations and frequencies to determine the best combination that can improve the quality and quantity of the flower produced.

Recommendations

Based on the results of this study, the following recommendations are made:

Further experiments should be conducted to determine the optimal concentration of Epsom salt and GA3 application interval for Dendrobium sp. orchids.
The use of GA3 in the right frequency can affect the quality of flowers and the duration of orchid flowers.
The combination of the selection of appropriate Epsom salt concentrations and GA3 application interval regulation needs to be carefully considered to optimize the flowering results.

Limitations

This study has several limitations that need to be addressed in future studies. These include:

The study was conducted on a limited number of plants, and further experiments should be conducted to confirm the results.
The study only investigated the effect of Epsom salt concentration and GA3 application interval on flowering of Dendrobium sp. orchids, and further studies should be conducted to investigate the effect of other factors on orchid flowering.

Future Directions

Future studies should focus on investigating the effect of other factors on orchid flowering, such as light intensity, temperature, and humidity. Additionally, further experiments should be conducted to determine the optimal concentration of Epsom salt and GA3 application interval for Dendrobium sp. orchids.
