Key solutions for the problems of forest trees micropropagation

Forests are the national capital of each country, whose protection and proper use of them, in addition to earning money, ensures the survival of environment. The endemic plant species are unique genetic reserves of each country due to the having some superior morphological traits adapted to environmental conditions, particularly their resistance to pests and diseases and unfavorable environmental factors. This makes the proliferation and protection of endangered species a vital issue; therefore, the need to use the methods that could meet the growing need for cultivation and proliferation is felt. Mature trees that have been able to withstand their survival in various atmospheric conditions, pests and diseases attack, and inadequate environmental conditions over the years are valuable treasures of genetic reserves. Tissue culture is a tool that can save the endangered tree species, which are not capable of reproduction. This biotechnological method could be effective in preserving endangered forest species through proliferation of species under laboratory controlled conditions and then cultivation in natural arenas. During the three late decades, around 31 endangered forest species have been propagated through micropropagation in the tissue culture laboratory of biotechnology department of Research Institute of Forests and Range lands.
