Increasing Soybean Production: A Key to Meeting Community Needs

In Indonesia, soybean production is a crucial aspect of the country's food security. However, the growth rate of soybean production is not high enough to meet the increasing demands of the community. One potential solution to this problem is to identify soybean varieties that have tolerance to standing water, also known as hypoxia conditions. Research in this area can provide valuable insights into the development of more resilient soybean varieties, which can ultimately lead to increased production and improved food security.

Exploring the Effects of 2.4 D and BAP on Embryogenic Callus Induction

This study aims to explore the effects of a combination of regulator growth substances 2.4 D and BAP on embryogenic callus induction of several soybean varieties in hypoxia conditions in vitro. The research was conducted by Bertryda Hastipa Manurung in the plant tissue culture laboratory of the University of North Sumatra from April to December 2016. The study employed a factorial complete random design (RAL) with two treatment factors: soybean variety and a combination of growth regulators.

Research Methodology

Experimental Design and Materials

The study was conducted in the plant tissue culture laboratory of the University of North Sumatra, using a factorial complete random design (RAL) with two treatment factors. The first factor was the soybean variety, which included Baluran, Yellow Gepak, and Grobogan. The second factor was a combination of growth regulators with a concentration variation of 2.4 D and BAP. The concentrations used were 5 mg/L 2.4 D + 1 mg/L BAP, 10 mg/L 2.4 D + 1.5 mg/L BAP, and 15 mg/L 2.4 D + 2 mg/L BAP.

Data Collection and Analysis

The parameters observed in this study included the percentage of callus growth, callus shape and color, callus weight, embryogenic callus histology, total chlorophyll content, protein concentrations, and the activity of superoxide dismutase (SOD) and peroxidase (POD) enzyme. The results of the analysis were then compared to determine the effects of the treatment factors on the resulting callus weight.

Results and Discussion

Effects of Treatment Factors on Callus Weight

The results of the analysis showed that varieties, a combination of growth regulators, and interactions between varieties and growth regulators have a significant effect on the resulting callus weight. This suggests that the combination of growth regulators and the soybean variety used can influence the growth and development of the callus.

Effects of Treatment Factors on Chlorophyll Content

Regarding chlorophyll content, the results of the t-test analysis showed a decrease after inundation. This suggests that the hypoxia conditions may have a negative impact on the chlorophyll content of the callus.

Effects of Treatment Factors on Protein Concentration

The yellow and Grobogan Gepak varieties showed an increase in post-inundation protein concentration. This suggests that these varieties may have a higher tolerance to hypoxia conditions and may be able to adapt to the changing environment.

Effects of Treatment Factors on SOD and POD Enzyme Activity

The yellow gepl varieties have increased the activity of the SOD enzyme, while the grobogan variety shows an increase in the activity of the POD enzyme. This suggests that these varieties may have a higher ability to cope with oxidative stress and may be able to adapt to the changing environment.

Conclusion

Implications for Soybean Production in Indonesia

This study provides an important insight into the effect of a combination of growth regulators 2.4 D and BAP in embryogenic callus induction in soybean varieties in hypoxia conditions. By utilizing varieties that are more tolerant of inundation, it can be expected that soybean production in Indonesia can increase, so that it can meet the needs of people who continue to increase. Further research needs to be carried out to explore the mechanism of inundation tolerance in these varieties and to develop further strategies in soybean cultivation.

Future Research Directions

Further research is needed to explore the mechanism of inundation tolerance in these varieties and to develop further strategies in soybean cultivation. This may involve studying the genetic and molecular mechanisms underlying the tolerance of these varieties to hypoxia conditions, as well as developing new breeding strategies to improve the tolerance of soybean varieties to standing water.
