Studies on biological characteristics of ginkgo hairy root culture

The comparative studies on properties of growth and cultivated conditions of seven transformed ginkgo hairy root clones were reported. Different clones display various phenotypes characterized by growth rate. The results show that the suitable inoculum is benefical to the growth of ginkgo hairy root. NH₄ ⁺/NO₃ ⁻, pH, sucrose, and inositol have important effects on the growth of ginkgo hairy root.
