Estimates of genetic parameter were observed at two years old of Alstonia scholaris progeny trial in Gunungkidul, Yogyakarta. The experimental design of the trial was laid out in Randomized Complete Block Design consisting of 48 families, 5 replications, 4 tree-plot and spacing of 4 x 2 meters. This study is aimed to observe the growth variation (height and stem diameter) and the estimates of heritability and genetic correlation among the two growth traits. The results of study showed that the tested families were significantly different for height and stem diameter. The estimate of individual heritability was high at around 0.53 and 0.44 for height and stem diameter, respectively. While the corresponding of family heritability was at around 0.67 and 0.63 for height and stem diameter, respectively. Positive and strong genetic correlation were found between height and stem diameter of this species at two years of age (rg = 0.94).

The aims of this experiment was to investigate effect of population sources and media composition toward shoot cutting growth of Alsonia angusiloba Miq. From two sprouts age. This experiment was arranged in completely randomized design with factorial setting. The research used 2 factors. i.e. population source (Banten,Pendopo,Lubuk Linggau and Solok) and media compositions (sand, cocopeat, husk charcoal. Sand : husk charcoal (4;1) and sand cocopeat (4 :1). The result showed that interaction of population source and media composition did not give any significant effect on parameters measured. Lubuk Linggau population produced the best of rooting percentage (31.19 %) from 3 month sprouts age and Pendopo population produced the best of rooting percentage (65.52 %), number of root (5.50) and length of root (2.79 cm) from 5 month sprouts age. Sand : cocopeat (4:1) media produced the best of number of root (4.14) and length of root (2.41 cm) from 3 mionth sprouts age. Sand media produced the best of rooting percentage (70.42 %), number of sprout (5.27) and length of sprout (2.82 cm) from spouts age. Rooting percentage, number and length of roots tended to increase from 3 month sprouts age to month sprouts age.

Vegetative propagation has an important role to produce high quality of seedling. Through vegetative propagation, the genetic potential of a mother tree will totally be inherited to the off-springs. Therefore, the success of stool plants preparation from selected mother tree is very important. The aim of study was to investigate the effect of populations and height of topping to sprouting ability of Meranti tembaga (Shorea leprosula Miq.) stool plants. This study was arranged in completely randomized block design with factorial. The two treatments used in the study were three populations (Muara Wahau, East Kalimantan; Kenangan, East Kalimantan and Ketapang, West Kalimantan) and four height of toppings (20 cm, 40 cm, 60 cm and 80 cm). The results of study showed that population were significantly different for the number of sprouts, length of sprouts, diameter of sprouts and number of nodus. While the height of topping were significantly different only for the number of sprouts. The best number of sprouts (6.82 buds), length of sprouts (18.41 cm), diameter of sprouts (2.14 mm) and number of nodus (7.10 nodus) was found at Muara Wahau population. While among the height of toppings, the best number of sprouts was found at 80 cm height (8,06 buds), followed by 60 cm (6,00 buds), 40 cm (5,08 buds) and 20 cm (3,86 buds). There were no significant differences on the interaction between population and height of topping for all measured characters.

Alstonia scholaris (L.) R.Br. is one of native and fast growing species in Indonesia. This species is potential for forest plantation. Its wood can be used for boxes, matches, heelpiece, crafts (mask and puppet), pencil slate, and pulp. This paper aims to study the growth of Alstonia scholaris at 6 month old in Sumber Klampok, Bali. This experiment was arranged in a randomized complete block design with provenances as treatment. The research used 5 provenances, i.e. Lombok (NTB), Jayapura (Papua), Solok (West Sumatera), Timor (NTT) and Bali. Material genetic from 46 parent trees were used and we observed 4 seedling of each patent trees with 6 replications. The result showed that provenances of Bali, Lombok dan NTT were the best provenances for survival rate, height, and stem diameter.

The aim of this experiment was to identify of survival percentage, height plant and stem diameter of Alstonia angustiloba progeny trial at 2 year old to support the provision of improved seed. This experiment was arranged in randomized complete block design. The research used 2 factors, i.e. population sources (Carita-Banten, Pendopo-Muara Enim, Lubuk Linggau-Musi Rawas and Solok-West Sumatera) and parent trees (43 parent trees). In this experiment, parent trees factor was nested in the population sources. The result shodwed that survival percentage, height plant and stem diameter of Alstonia angustiloba progeny trial at 2 years old in Wonogiri were 82.07 %, 2.43 m and 2.85 cm, respectively.
