Respon Pertumbuhan Semai Tanjung (Mimusops elengi Linn.) terhadap Intensitas Cahaya (Response of Seedling Growth of Tanjung (Mimusops elengi Linn.) to Light Intensity)

The intensity of sunlight and the adequacy of nutrients in the soil greatly affect the growth and development of a plant because they will affect the process of photosynthesis. The type of plant itself largely determines the need for sunlight. Seedling tanjung (Mimusops elengi Linn. ) is a type of plant that requires sunlight at the beginning of its growth. This plant also can adapt to the environment and air pollution, so that it can be developed as a protective tree in urban forest development programs. This research aimed to determine how the Tanjung seedling growth responds to the percentage of light intensity in the Arboretum of the Faculty of Forestry, Tadulako University. The study used a randomized block design with the proportion of light as the treatment. The treatments consisted of 100%, 55%, 30% and 10% light intensity. The results showed that the percentage of light intensity affected the development and growth of tanjung seedlings. The treatment with 100% and 55% light intensity gave the best results for the growth of tanjung seedlings, especially for the parameter of the number of leaves of the seedlings, and the sturdiness quotient of seedlings.
