Abstract
This study would select native plant's species that have been scientifically validated. We collect its provenance and the establishment of the wild gene pool. Our works have that collecting native species of medicinal plants, planning in ex situ gene pool, planting, monitering, and management in plants and gene gardens, and applications in pest prevention and control of medicinal plants. The benefits are expected that establishment in ex situ gene pool of native medicinal species and evaluation in biological products about natural pest prevention.There were various medicinal effects of plant species from the scientific literature, such as: antioxidant, anti-inflammatory, anti-bacterial, insect-resistant, cytotoxic, ... and many other effects. The effects of antibacterial, insect-resistant and cytotoxi may be selected by shielded crops. The species of Litsea cubeba have these three effects, that's a good species for shielded crop.
In this project at 2015 - 2016, the short term change of climate seem to be small to affect to plant phenology of this study.
