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

A Progeny test of Araucaria cunninghamii seedling seed orchard was established comprising of eighty open–pollinated families collected from six seed source (Fak-fak, Sorong, Serui, Wamena, Manokwari and Queensland). The trial was designed as a Randomized Complete Block Design (RCBD) which comprised 80 seedlots, 4 tree- line plots with 4 replicates. At 18 months of age there were significant differences among seed sources for tree height and stem diameter. The survival rate of all seed sources was high (96.7 – 100%). Differences between families within seed source were significant both for height and diameter growth. Heritability estimates for height were moderate (h2f = 0.42, h2i = 0.19) and also for diameter (h2f = 0.57, h2i = 0.30). Genetic correlation between height and diameter was string (rg = 0.80).

Abstract

A progeny test of Araucaria cunninghamii seedling seed orchard was established in 2008 at Bondowoso, East Java. Eighty open-pollinated families collected from six seed sources (Fak-fak, Jayapura, Serui, Wamena,  Manokwari and Queensland) were tested. The trial was designed as Randomized Complete Block Design (RCBD) comprised of 80 seedlots, 4 tree- line plots with 4 replications. The anitial spacing was 4 m x 2 m. The growth analysis at 5 years old was aimed to know performance of 6 seed sources.The result showed significant differences between families within seed source for both height and diameter growth. The average of height growth was 7,0 m and diameter was 5,1 cm. Indivual heritability estimates for height and diameter were 0.32 and 0.48 respectively while family heritability estimates for height and diameter wer 0.49 and 0.72 respectively. Genetic correlation between height and diameter was strong and positive (rg = 0.83).

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.

Abstract

Araucaria cunninghamii sebagai bahan baku pulp serat panjang perlu dipertimbangkan di masa mendatang yang saat ini masih diimport dari negara lain untuk memenuhi kebutuhan bahan baku pulp serat panjang di Indonesia. Sumber benih unggul dari jenis tersebut perlu dipersiapkan sejak dini untuk mengetahui peningkatan genetik yang dihasilkan. Kombinasi uji provenan dan uji keturunan A.cunninghamii di Bondowoso, Jawa Timur adalah salah satu penelitian yang dibangun untuk menghasilkan benih A.cunninghamii yang berkualitas di masa yang akan datang. Plot ini dirancang menggunakan rancangan acak lengkap berblok (RCBD) dengan 28 famili, 4 pohon per plot dan 8 blok dengan jarak tanam 4 x 3 m. Hasil analisis menunjukkan bahwa pada umur 5 dan 10 tahun rerata tinggi dan diameter pohon berturut-turut sebesar 5,47 m; 8,20 cm dan 16,05 m; 20,59 cm, rerata volume pohon/ha sebesar 8,02 m3/ha dan 74,52 m3/ha; riap volume pohon sebesar 1,60 m3/ha/tahun; 7,45 m3/ha/tahun. Pada umur 5 tahun berbeda nyata terhadap diameter batang, sedangkan pada umur 10 tahun menunjukkan perbedaan yang nyata antar provenan terhadap kedua sifat yang diukur. Pada umur 5 dan 10 tahun nilai heritabilitas famili dan individu tergolong sedang, h2f = 0,4 - 0,5 , h2i = 0,2 - 0,3 dan h2f = 0,40 - 0,47, h2i = 0,28 - 0,29 sedangkan heritabilitas di dalam famili (h2wf) sebesar 0,41 - 0,48. Korelasi genetik umur 5 dan 10 tahun cukup tinggi (rg=0,62; 0,82). Taksiran peningkatan genetik untuk tinggi pohon dan diameter batang dari hasil seleksi di dalam famili adalah sebesar 0,10% dan 0,07% pada umur 5 tahun serta 0,53% dan 1,01% pada umur 10 tahun.
