Role
In vitro biodiversity conservation of recalcitrant and critically endangered plants
Development of novel sterilization protocols for recalcitrant and woody plants collected from wild sites and glasshouses. Application of unconventional weaning methods for Critically Endangered tree species. Use of supporting materials and closures are being investigated. Chromosome doubling in vitro and breeding of endangered plants; and model systems and its application in phylogenetic studies. Development of autotrophic micropropagation systems in recalcitrant plants such as Ramosmania to produce quality propagules. Application of forced ventilation and CO
