A Light Adaptability of Wild Evergreen Ternstroemia gymnanthera for Development of Material of Plant of Indoor Garden

초록

This study was performed to grasp the introduction of Korean wild evergreen broad-leaved tree, Ternstroemia gymnanthera, as a plant of indoor garden, and to figure out the light-adaptability under the four types indoor lighting and to provide the introduction plan. The experimental plants, Ternstroemia gymnanthera was purchased from the farmhouse in Jeju-do as a year plant, and it was experimented after the acclimation in the glass-green house of general farm of Gyeongnam National University of Science and Technology for 40 days. The experiment was performed for 1 year more from September 10, 2014 to September 30, 2015. The results of the experiment are as follows. When Ternstroemia gymnanthera is introduced as a plant of the indoor garden, the optical fiber, fluorescent lamp, and LED light in order are suitable to introduce as the proper lighting. In the case of the three-wave light, the growth and development was the worst among the 4 introduced lighting systems, therefore, the growth of Ternstroemia gymnanthera under the three-wave light was incongruous generally. The withering appearance was existed seriously by 500lux. Some leaves were fallen off, but generally smooth growth and development was done in the range of the 1,000lux to 2,000lux. The best intensity for the growth was under the condition of the 1,000lux. When the fluorescent lamp, and LED light are introduced, the most proper luminous intensity is the 2,000lux. When the optical fiber is introduced, the most efficient intensity is the 1,000lux. Generally the smooth growth and development is done under the more luminous intensity. As the result, the wild Ternstroemia gymnanthera is the species of tree to substitute the Ficus benghalensis, or Ficus retusa which is the foreign species, as a central tree or upper tree as well as pot tree, and it is expected to introduce sufficiently as a plant of the indoor garden.
