Abstract

Because it generates the zero-calorie sweeteners steviol glycosides, Stevia rebaudiana is a valuable medicinal plant that offers herbal care for diabetic patients. The effects of applying vermicompost water extract and inoculating S. rebaudiana with Serendipita indica on the growth of the plant were investigated in this study using an in vitro experimental design that was completely randomized. The application of vermicompost water extract and inoculation with S. indica had a significant impact on the majority of the plant's growth parameters, as indicated by the results. S. rebaudiana inoculated with S. indica exhibited the greatest root length, chlorophyll content, and dry weight of aerial parts. Additionally, when inoculated with vermicompost water extract, S. rebaudiana demonstrated the maximum chlorophyll content and the ratio of fresh weight of roots to fresh weight of aerial parts. Large-scale application of the findings from this study is possible in the tissue culture of medicinal plants. Conversely, in sustainable agriculture, the utilization of water extract vermicompost and S. indica fungus may lead to enhanced vegetative products and, consequently, secondary metabolites in medicinal plants.

Highlights

  • The study employed a completely randomized in vitro experimental design to investigate the effects of vermicompost water extract and inoculation with Serendipita indica.
  • Results showed a significant improvement in most growth parameters of rebaudiana when treated with vermicompost water extract and inoculated with S. indica.
  • Plants inoculated with S. indica had increased root length, higher chlorophyll content, and greater dry weight of aerial parts.
  • The maximum chlorophyll content and an improved ratio of fresh weight of roots to aerial parts were observed in plants treated with vermicompost water extract.
  • The study suggests that these treatments could be scaled for large-scale tissue culture of medicinal plants and could enhance vegetative growth and secondary metabolites in sustainable agriculture.
