Abstract

Cyclea barbata Miers, a species within the Menispermaceae family, holds significance in medicinal and beverage applications. In vitro propagation is a common practice for conserving this plant; however, a comprehensive investigation of its growth characteristics within controlled greenhouse and natural field environments is essential. This study aims to determine the optimal planting media for acclimatization and the subsequent growth of Cyclea barbata Miers propagated from in vitro cultures. The experimental design encompasses two phases: 1) greenhouse acclimatization and 2) field growth. Various planting media, including combinations of sterile soil, manure, and husk charcoal, were rigorously evaluated during the acclimatization phase. Following the acclimatization period, the plants were transferred to the field. Multiple parameters were assessed: plant growth percentage, branch and node counts, leaf dimensions (length and width), and leaf wet and dry weights. Our findings reveal that a planting medium comprising sterile soil, manure, and husk charcoal provided the best performance growth outcomes during acclimatization. Furthermore, we observed that plant age exerts a discernible influence on the growth dynamics of Cyclea barbata Miers.
