Abstract

As a part of tree improvement project of sengon (Falcataria moluccana L. Nielsen) several progeny test  were established in December 2011. One of those progeny test  was established in Bondowoso, East Java.  Row Column Desgin (Incomplete Block Design) was used as experimental design involving 70 families (9 Papua provenance and 1 provenance Solomon), 4 replications (blocks), 4 trees per plot and a spacing of 3 x 2 m. Observations were made at the age of 6 and 12 months, including recorded the percent of survival plants, height, diameter and the gall rust incidence. Results showed that in general, the early growth of individual plant in this plot demonstrated a fairly good performance with the survival rate of 98.5% (6 months old), and 96.9% (1 year old). The early growth of sengon varied significantly between provenances. The best growth demonstrated by provenances from Meagama, Holima and Hobikosi. Early estimation of individual heritability of plant height categorised in low (h2i = 0.07 to 0.11, h2 = 0.16 to 0,21) , whereas individual heritability of diameter were catagorised in medium (h2i = 0.08 to 0.11, h2f = 0.15 to 0,43). Moreover, the positive value of the genetic correlation revealed between height and diameter (0.88 and 0.85). Several individual trees originated from Holima, Meagama and Elagaima exhibited 0% of gall rust disease incidence.

Abstract

Combination of provenance progeny trial of Acacia mangium from Claudie River-Queensland- Australia was established in Pelaihari, South Kalimantan. The objective of this research is to find variation on diameter, wood specific gravity and fiber lenght between provenance seedlot and family within provenance seedlot in provenance progeny trial of A. mangium on 22 months old.The results showed that the mean of wood specific gravity and was 0.40 and mean of fiber length was 0.89 mm. Variation of diameter, wood specific gravity, and fiber length were significant difference among provenance seedlot or between family within provenance seedlot in the trial. Individual heritability of diameter, wood specific gravity, and fiber length were medium (hi 2=0.49 for diameter; hi 2=0.33 for specific gravity and hi 2=0.39 for fiber length). The results of investigation from this trial indicate that diameter, wood specific gravity, and fiber length are necessary to be used for tree selection to improve growth wood quality in the combination of provenance progeny trial of A. mangium.

Abstract

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.

Abstract

A provenance stands of sengon Solomon (Falcataria moluccana (Miq.) Barneby & JW Grimes was establishhed in Bondowoso, East Java in 2011. One provenance seed consisting of 25 families originated from Solomon Island were used in this trial. Provenance stands was designed by rows column design (incomplete block) involving 8 blocks, 4 trees per plot (plot tree) with a spacing of 3 m x 2 m. Several characters were observed i.e: survival rate, height, diameter and the presence of gall rust diseases; the observations were undertaken every 6 months from 6 months old up to the age of 18 months. The results showed that the mean of survival rates ranging from 75% to 90%; with the average survival rate of 84.83% (6 months), 83.26% (12 months) and 81.05% (18 months). The mean height and diameter of 6 months old (2.42 m, 2.97 cm), 12 months old (4.74 m, 5.56 cm), and 18 months old (7.35 m, 7.39 cm). Varian analysis of height, diameter, disease severity and intensity showed that there were no significant differences between families. All of families attacked by gall rust disease, however family number 2, 8 and 23 showed the lowest respond of attack compared to other families. Therefore, those families can be recommended for future development in terms of toleration to the gall rust disease.

Muell Wood from Progeny Test Second Generation Tree in Wonogiri, Central JavaAbstractEucalyptus pellita F. Muell (E. pellita) is one of the fast growing species, which is being developed through tree breeding program. The development of this species had produced good results in the genetic growth characteristics in the first and second generation of progeny trials. The objectives of this research were determining the variation of wood chemical components, clustering and rating the plus trees to support the development program in next generation of the progeny trial, especially in pulp and paper purposes. The materials were the 61 plus trees of E. pellita trees 9-years-old from second generation of progeny trial, Wonogiri in six different provenances. The sampling used the increment borer system at 90 cm from the surface. Materials from the increment borer were milled to 40 - 60 mesh of wood powder. The wood chemical properties were tested according to ASTM standards. It included ethanol-toluene and hot-water solubles by sequential extraction as well as holocellulose, alpha-cellulose and lignin contents. Data analysis used descriptive and clustering analysis. The results showed that the range values of ethanol-toluene extractives and hot water content respectively were 1.87 - 10.92 % and 0.64 - 10.00 %. The range values of holocellulose, alpha-cellulose and lignin contents were 72.89 - 79.91 %, 41.84 - 54.85 % and 22.12 - 36.61 %, respectively. The high values of coefficient of variation were observed in extractive content levels (30,78 - 82,91 %). Based on the simple rating, which was resulted from descriptive and cluster analysis, it gave the best 13 individuals of plus trees for pulp and paper purposes.
