Plant materials
Both the invasive and native species selected are perennial herbaceous
climbing vines that have green photosynthetic stems year round. The
stems of all these species can be used for vegetative reproduction.
Vigorous stems of the invasive species M. micrantha and the
native species (Pharbitis nil , Paederia scandens ,Pueraria lobata ) were collected from wild populations near the
Guangdong Academy of Agricultural Sciences, Guangzhou, China, and
cultivated as raw plant materials for subsequent culture.
