Introduction:

Established in August 2008, this new research group aims to carry out researches and practices on ex situ conservation and re-introduction of rare and endangered plants in China.

At present, orchid plants are our main research target. We focus on the effects of habitat fragment on species diversity, genetic structure and reproductive process of local orchids. We have set up a system for long term monitoring on the species diversity, population dynamic, population spatial distribution, reproductive phenology and pollinators of all orchid species in Green Stone Forest, which is a part of Xishuangbannan National Nature Reserve. For some rare species which become locally extinct due to over-collecting as valuable Chinese medicine, seeding from in vitro culture of seeds will be re-introduced to their original habitats, and many research work will focus on the effects of genetic structure and population size on reintroduction.

Current Research Tasks:

1. Effects of Clonal Growth on Sexual Fitness and Its Ecological Significance in Hedychium villosum Wall. var. tenuiflorum Wall.ex Bak.

Research the impacts of clonal growth on mating system, quantify the effects of clonal growth on bisexual fitness by field investigation of natural population, observation of flowering characteristics and pollinator behavior, different control experiments and the application of  molecular marker.

2. Protocorm Conservation of Wild Orchidaceous Plants 

Establish protocorm resource bank of wild orchidaceous plants, explore the methods, conditions of long-term conservation of orchidaceous protocorm; concern relative issues of the genetic diversity maintain in long-term protocorm conservation.
