Institute of Subtropical Crops and Tea Industry

Institute has been functioning since 1930. Its multi profile researches have been the base of producing high and stable harvest of tea, citrus and subtropical fruit culture in the most southern subtropics and developing recycling industry

Main directions of research

  • Development of frost resistant, immune, high productive forms and breeds of subtropical fruits and their seedlings (citruses, kiwi, peihoa, subtropical persimmon); elaboration of their nursing technologies.
  • Development of high quality and high productive Georgian selective varieties of tea. Their biochemical and technological research to receive other kinds of products.
  • Elaborating the intervention methods related to integrative resistance of subtropical crops against harmful organisms through maintaining ecologically pure biocenosis; phytosanitary research of the subtropical zone to identify existing biodiversity.
  • Developing intensive technologies of breeding, laying out and nursing for tea, citruses and other subtropical crops.
  • Perfection of fertilization system of subtropical crops through considering soil fertility, biological characteristics of plants and environmental issues. Study influence of involvement of fertilizer nitrogen in soil nitrogen mineral and organ mass.
  • Using local plant, tea and citrus raw material to research and develop technological parameters and technical capacities for producing high quality food and dietary-preventive products, having biological activity.
