Cempaka wasian (Magnolia tsiampaca (Miq) Dandy )) is one tree species with high economic value. Cempaka wasian development in the form of community forests in the province of North Sulawesi needs to be supported by the availability of quality seeds. Generally, plant has different effect towards light it received. This study aimed to determine the effect of shade intensity on the growth of seedlings in the nursery. The experimental design used in this research is completely randomized design. The treatments were tested among other shade with a density of 25 % (± 37,350 lux light intensity), the shade with a density of 50 % (± 19,100 lux light intensity) and shade with a density of 75 % (± 8,018 lux light intensity). The results showed that treatment with 50% shade density (± 19,100 lux light intensity) gives the best effect on the growth and quality of seedlings in the nursery.

Secondary forest of Indonesia covered about 24.2 % of total land area and dominated by post logging forest. The discourse to manage all forest area into Forest Management Unit (FMU) as the smallest management unit has been established, including post logging secondary forest. Therefore, understanding the diversity of secondary forest vegetation will help to decide its future management. This research aims to analyze composition, diversity and structure of post logging secondary forest at Nunuka, North Bolaang Mongondow of North Sulawesi. In order to accomplish the proposed objectives 30 plots of 20 m x 20 m were established in research area where number and name of tree species were identified and counted. The research was conducted on November 2014. The result recorded 84 tree species in research area. Anthocephalus macrophyllus dominated tree phase, whereas Eugenia sp. dominated both of poles and sapling. Shannon-Wiener index indicated low and medium diversity, whereas species abundance of tree, ploes and sapling were almost spread evenly. Vegetation density over all vegetation phases was 485.83 tree/ha, the average basal area of the forest was 35.15 m2/ha and the size class distribution did not resembled a reserved J-shaped pattern as found in primary forest. However J-shaped pattern showed in graphs of ten dominant species in both of tree and sapling level.

Technical rehabilitation planning of BPDAS Tondano on coastal area has reached 10,000 hectares, thus require many seedlings. Nyamplung has potential as rehabilitation plant in coastal at the same time it can support national demand of biofuel. However the nurseries of nyamplung in North Sulawesi are not optimal and need appropriate information of weaning method. This research used completely randomized design with three treatment factors, namely 1) Cutting the leaves consist of two levels ie D1 (pair leaves) and D2 (intact leaf); 2) Cutting intact seeds, consists of two levels i.e B1 (removed seed) and B2 (intact seeds); and 3) Cutting the roots lenght consist of three levels i.e A1 (5 cm), A2 (10 cm) and A3 (15 cm). There were 180 seedlings taken from seed that germinated using cocopeat media. Results of variance analysis showed that the applied treatment only affect the heigth growth. The survival rate is not affected by all treatments or in the other words survival rate reached 100 %. The treatments on leaves and seeds gave significant effect, on the contrary with root treatment. The treatment of intact leaf (D2) and intact seeds (B2) produced the best height growth responses i.e 4.60 cm and 4.63 cm.

The estimation of genetic parameters for stem diameter and plant height of ironwood (Eusideroxylon zwageri T. et B.) was conducted in a progeny trial in Bondowoso, East Java at the age of 5,5 years. The trial was arranged in an incomplete block design, which comprised of 49 families from three provenances (Batanghari, Berau and Kutai Kertanegara) with 4 replications and single tree plot. Families of Batanghari provenance showed the best growth of stem diameter and plant height compared with another provenance. There was significant difference in plant height between families within provenance, whereas stem diameter was not significantly different both of between provenance as well as between families within one provenance. Non-genetic or environmental factors provide considerable influence on plant growth in the progeny test of ironwood until the age of 5.5 years; it was indicated by the residual variance component. Individual heritability for plant height was considered as high (0.37) and stem diameter was considered as moderate (0.26). There was a strong genetic correlation between the stem diameter and plant height (0.95). This information is very important for future genetic improvement of ironwood.
