The study was conducted to develop methods for planting stock production by shoot cuttings. The objectives of the study were to identify the effect of parent tree age, shoot age and rooting media on the growth of shoot cuttings. The study was conducted in 2 experimental steps. The first was to examine the effect of parent tree age and shoot age on the groeth of cutting: parent tree age class of 5 years (KU-1), 6-10 years (KU-2), 11-15 years (KU-3) and 16-20 years (KU-4), and shoot ages of 3 and 4 months. The second was to test 6 rooting media types (volcanic sands, soil, rice husk charcoal, coconut husk, sand + rice husk charcoal/4:1 and sand + coconut husk/4:1). The results showed that shoot cuttings from root cuttings grew successfully. It reached 90-100% of survival rate. Parent tree age and shoot age significantly influenced the number of roots with the highest root number was 5,42 from 4 months shoot taken from KU-4 root cuttings. Types of media significantly affected rooting rate with the best was 98% shown in sand + rice husk charcoal (4:1) media.

Calophyllum inophyllum L. is one of species that has been identified as a source of oil suitable for biofuel, cosmetics and medicine. Until now, the propagation of this species uses generative methods. In the forest tree breeding program, after a plus tree is selected a vegetative propagation technique must be developed to maintain the genetic potential of the parent tree. This study was conducted to determine the growth response of selected clones in Provenance Seed Stand of C. inophyllum in Wonogiri, Central Java propagated using the grafting method. The research used was arranged in Randomized Completely Design with 22 clones as the parent tree treatments. Each treatment consisted of 5 grafted seedlings and repeated in 4 times. The results showed that the survival percentage of grafted seedlings ranges from 15 – 100 % at 2 months of age, which showed a fairly high variation among the selected clones. Increasing the success of the grafting technique on the C. inophyllum clones still needs to be done so that it can provide vegetative material for clone testing and operational planting. It is important to be conducted in order to produce C. inophyllum stands with high fruit productivity and oil yield.Keywords: Calophyllum inophyllum, vegetative propagation, seedling growth, nursery

This study was conducted to evaluate plant growth of Intsia bijuga at 5 years old in Sobang, Banten for supplying good genetic material in the future. Establishment of the trial was conducted in 2007 using Randomized Complete Block Design (RCBD) that consisted of 6 blocks, 100 families nested in 10 provenances, 4 treeplot for each family with a spacing of 4 x4 m. Measurements were taken periodically every year on the survival percentage, total height and stem diameter at the breast height or dbh. At the age of 5 years showed that the significant differences among provenance in survival percentage that ranged from 41.61 to 65.11 %, average of plant height were 1.04 to 2.82 m and dbh 1.24 to 1.59 cm. The growth variation families also showed significant differences in height and diameter. The survival rate ranged from 12.5-91.67 %, average plant height were 0.52-2.55 m and dbh 0.90-2.44 cm. Individual tree heritability estimate for height was height (0.344) while that of diameter was moderate (0.259). Family heritabilities for height and diameter was considered moderate, namely 0.573 and 0.491 respectively. Genetic correlation between height and diameter growth was positive and high (0.834).

Teak (Tectona grandis) is one of popular and important carpentry wood in Indonesia. However teak production for carpentry material cannot balance the increasing need for domestic and export market. The increased production from small holder forest can be alternative way to supply national wood need. Therefore science and technology play role to support forest productivity eg superior seedling from vegetative propagation. The preparing of superior seed took several steps i.e. selection from mother tree, genetic material extraction, grafting activity using budding technique, hedge orchard establishment, and mass production used cutting rotted or tissue culture. From clonal test we can derive superior seed which adaptive with development location and has better productivity.

Trial research of teak clones was located in Wonogiri, Central Java. This research was conducted in order to evaluate the growth performance of teak clones that can be developed for forest plantation and private forest. Establishment of teak clones test was conducted in 2002 using 20 clones with Randomized Completely Block Design/RCBD consisting of 5 ramets and 5 replications with plant spacing of 2 m x 6 m . The second plot was established in 2005 using 100 clones with RCBD that consisted of 3 ramets and 5 replications with spacing of 2 m x 6 m. The observation and measurement on height and diameter at breast height/dbh were carried out periodically in every year to determine the level of plant growth The results showed that the average growth at the age of 5 years in two test plot clones are height from 8,73 to 9,97 m , tree diameter from 8.61 to 13.14 cm and tree volume estimated 0,046 - 0,103 m3. Estimated heritability clones of tree height and diameter were 0,18; 0,29 in plot 1 and 0,32; 0,38 in plot 2.

White teak (Gmelina arborea Roxb) is one of the types developed for the development of plantations, this species is an exotic tree that grows quickly, the planting technique is not difficult and has a good economic value. The wood is used for various purposes, especially for the manufacture of construction materials, carpentry, plywood, matches, containers and other wood craft materials. One aspect that determines the success of plantation development is the availability of seeds, especially quality seeds that are superior genetically, physically and physiologically, available in sufficient quantities, on time and have the ability to adapt to the environment in which they grow. The development of this plant needs to be accompanied by a breeding program, one of the forest plant breeding activities is exploration. Exploration activities of a type of plant in its natural habitat are important to support research and development activities of an institution and to meet market needs for these seeds. The purpose of seed exploration is to get white Teak seeds that represent a variety of habitats to support breeding activities. Exploration of white teak seeds is carried out in Kalianda (South Lampung), Bondowoso (East Java), Bantul (Yogyakarta), Parung Panjang (West Java) and Lombok (West Nusa Tenggara). The results of the exploration obtained 108 mother trees from Kalianda 25 mother trees with seed size (18.32 mm; 10.25 mm), Bondowoso 30 mother trees (17.78 mm; 9.64 mm), Bantul 21 mother trees (19, 24 mm; 11.40 mm), Parung length 15 mother trees (19.41 mm; 9.42 mm) and Lombok 17 mother trees (18.58 mm; 10, 31 mm).
