The intent and purpose of this study was to investigate the influence of growth regulators and frequency of administration on the growth and development of plant resins (A. Lorantifolia Salibs). This research was conducted in December until February 2010 and held at the experimental garden of the Faculty of Agriculture University Muhammadiyah of Malang, with an altitude ± 550 meters from sea level with a total rainfall 1.388 mm. The tools used in this study is an analytical balance, oven, mixer, stationery, paper millimeters, measuring cups, hand spray, plastic bucket, and shove camera. Materials used in this study was 6 months old growth damar extracted from the seed production area of RPH Kedungrejo BKPH Pujon, plant growth regulators (IAA, IBA GA3, Atonik) and distilled water. This research was conducted using a randimized block design (RAK) factorial, consisting of two factors with three replications. Factors I is a kind of plant growth regulators (Z), consisting of 4 levels, namely : Z1 (IAA 0,3 mg/l), Z2 (IBA 0,2 mg/l), Z3 (GA3 0,4 mg/l), and Z4 (Atonik 0,2 mg/l). The second factor is the frequency of (F), consisting of 3 levels, namely : F1 (the frequency of 1 time), F2 (frequency of 2 time/) and F3 (frequency of 3 time). Variables observed high increase of seedling, stem diameter, leaf number, length of root, root number, fresh weight and dry weight. From the observation results showed that of growth regulators GA3 0,4 mg/l and the frequency of 2 time (Z3F2) gave the best results compared with other treatments for all variable including the addition of observation height, stem diameter, leaf number, length root, root number, fresh weight and seedling dry weight resin.
