Abstract

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.

Abstract

The study of daily activity of (Hylobates moloch Audebert 1798) was conducted in Cikaniki. Ciawitali and Pasir Bivak TN Gunung Halimun for two months from June to July 1999.Commontly the daily activity for Jawan Gibbon are resting 39.1%, feeding 30.3%, moving 24.1% and other social activity 6.5% in average.Based on the meaning of activity category, the most for feeding;activity used by subadult (45%), moving for juvenile (33%), resting for infant (82%) and social for juvenile (15.72%).The least social activity was done by subadult category (0.4%). The space area for Jawan Gibbon activity was done at 5-15 meter (23%), 16-25 meter (43%), 26-35 meter (30%) and upper or top canopy at 35 meter from ground (4%).On this study also indicated that this gibbon turn down until to 1.5 meter from ground at lepus (Ammonium pseudopoetens) vegetation.

Abstract

Genetic parameters were estimated for growth traits of Ampupu (Eucalyptus urophylla S.T. Blake) progeny test grown in Southern Central Timor - East Nusa Tenggara Province, Timor Island. When the trial was one year old data were collected from 45 half-sib open pollinated families and assessed. There were genetic variations in height and diameter among families of E. urophylla. Growth traits had moderate heritability, both individually and in family, i.e. 0.28 and 0.55 for height and 0.41 and 0.66 for diameter, respectively. Genetic correlation between height and diameter was strong (0.96). However, the estimation of genetic parameter should be interpreted carefully since the trial was very young. Re-assessment of the trial should be carried out periodically to provide better understanding of the species regarding the dynamic of the genetic interaction between the species and its environment, effective age of selection and prediction of genetic gain.
