【 摘 要 】

Kemenyan known as Sumatran benzoin is North Sumatera local species that produce high valuable rosin and prospective export comodities. However, sustainability of Sumatran benzoin production has many constraints such as instability of resin production, lack information of propagation technique and traditional management system. Until now, comprehensive information for Sumatran benzoin propagation system still not determined yet. The objectives of this research were (1) to get information about propagation technique of Sumatran benzoin and its suitable growing medium and 2) to get information on adventitious root formation in Sumatran benzoin cuttings. Cutting materials (Toba benzoin and Durame benzoin) were originated from 1 year old seedling propagated by seed. Media used were combination of sand : rice husk (1:0 v/v; 1/1 v/v). Results showed that interaction between media and benzoin species significantly affected primer and secondary root lenght. While planting medium significantly improved secondary root length and number. Benzoin species significantly affected primary and secondary root lenght, and secondary root number.
