Morphological characteristics of woody root systems in tea (
Camellia sinensis) varieties were surveyed on 19, 28 and 39 year-old plants that were propagated by cuttings. Differences of woody roots were found in number per stock, thickness, length, number of branching, bending character, formation of shallow roots, and conditions of root surface. In several varieties, correlations in some traits were examined between 3-year-old seedling and matured plants. Results show that some of root traits of matured plants could already be identified in young seedling stage. In addition, woody roots of 60-year-old direct seeded plants were also surveyed. Those information of root system in tea plant are effective to improve efficiency of fertilizer absorption and productivity of the plant.
