Abstract

Study on growth of jabon (Anthocephalus cadamba Miq) as native tree species that suitable for pulpwood on ultisol-soil land is required, as most pulpwood plantation occur in this type of soil. The experiment was conducted in ex Acacia mangium (second rotation) in Riau to evaluate the growth performance of jabon on marginal land ultisol soil. This study assigned experiment plots of jabon with three planting spaces (2 m × 2 m; 2 m × 3 m and 3 m × 3 m) and four blocks in Randomized Block Design. The poor growth was exhibited by jabon on marginal land ultisol. It was suggested that the poor growth related to the negative effects of low N and P soil, high Al soil, and threats of pest, disease, weed as well. The result study indicated that jabon was not suitable to be developed as pulpwood species in marginal lands ultisol of pulpwood plantation in Riau.

Abstract

Breeding for cajuput in Indonesia has moved into advanced generation breeding cycle through establishing second-generation progeny trial. A series of selection would be practiced in the trial before converting into a seedling seed orchard to produce genetically improved seed. In this study, a series of selection, followed by prediction of genetic gain will be observed in the second-generation progeny trial of cajuput established at Gunungkidul. The trial was laid out in randomized complete block design (RCBD), 65 families, three tree-plot, four replications, and spacing of 3 × 1,5 meter. Measurement was conducted on height and diameter at 2 years age. In the trial, within-plot selection has been practiced phenotypicaly by retaining one of the best tree out of the three tree within each plot. Succesive family selection was then simulated from the result of within-plot selection. Results of study showed that estimates of heritabily for diameter were higher than that for height. Genetic and phenotypic correlation between the two traits was moderate at around 0.57. Within-plot selection practiced in the trial resulted positive selection differential for all measured traits. Diameter showed higher coefficient weight of selection (0.4280) than height (0.0406) which indicates that the practiced within-plot selection was more imposed for diameter than that for height. Genetic gain from within-plot selection calculated using selection index were 20.76% for diameter and 12.73% for height. Simulated family selection using the same coefficient weight as within-plot selection resulted lower genetic gain at around 12.26% and 7.52% for diameter and height, respectivelly.

Abstract

Nyamplung and Malapari a potential bioenergy crops on marginal land to be developed on the coastal land. The constraints of the coastal land is the less of water and soil nutrient. Input technology is needed in order to suceed the crop planting such as using bio fertilizer. Mycorrhizae plays an essential role in helping plants to absorb phosphate and increase the resistance to drought. Trichoderma spp involves in producing beneficial hormones for metabolism and helps break down organic matter. Utilization of biofertilizer is still rarely used as treatment in bioenergy plant seedlings. This study aimed to determine the quality of nyamplung and malapari seedlings after mycorrhizal and Trichoderma spp application in the nursery. Experiments were arranged in a complete randomized block design (RCBD). The treatment of media: soil as control (T), soil+organic fertilizer with ratio of 3:1(TK), soil+organic fertilizer+mycorhizae 10 g (TKM), soil+organic fertilizer+Trichoderma spp 10 g (TKT), soil+organic fertilizer+mycorrhizal 10 g+Trichoderma 10 g (TC). Application was done when the seedlings reached 1 (one) month old. Biofertilizer was sown around seedling roots. Each treatment consisted of 50 samples and 3 replications so the total seedlings were 750 seedlings. The results showed that after 6 and 12 months treatment malapari with organic fertilizer + mikoriza + Tricoderma spp (TC) gained 67.5% taller and 427% larger on dry weight of leaf than the control, whereas in nyamplung seedlings, TC treatment resulted better growth with diameter 8% larger, root length 78.56% longer, and total dry weight 7.88% heavier compared to control (T).

Abstract

The conventional propagation of tohiti rattan still faces problem because of infrequent fruiting season and limited seed production. Somatic embryogenesis is an alternative technique to solve the problem. The purpose of this experiment is to obtain the best growth regulator treatments for embryogenic callus and somatic embryo formation of tohiti rattan. Murashige and Skoog (MS) basal medium was used as growth medium. The experiment was conducted in three stages: seed germination, embriogenic callus induction and somatic embryo induction. MS medium without plant growth regulator was used for aseptic seed germination. MS medium supplemented with growth regulator of BA (Benzyl adenine) of 0.5 – 2.0 mg/l was used for embryogenic callus induction. MS medium supplemented with BA 1.0 mg/l in combination with hormone 2.4-D of 0.0 – 1.0 mg/l was used for somatic embryo induction. The seed germination percentage, visual performance on embryogenic callus and somatic embryo were observed. The results showed that the percentage of aseptically seed germination reached 90%. MS medium supplemented with 1.0 mg/l BA is the best media for embryogenic callus induction with friable, white and yellowish of callus which was observed after four months of induction culture. The BA of 1.0 mg/l in combination with 2.4-D of 1.0 mg/l provided the highest number of the formed somatic embryo.The performance of somatic embryos formation from this treatment was likely as zygotic embryo.

Abstract

Multiplication of teak clones can be conducted by using vegetative methods either macro or in vitro. In this research, several teak clones collected from Gunungkidul and Wonogiri were propagated using bud grafting technique to know the variation of their growth ability in the nursery. This research arranged in nested design, with 25 clones nested in 3 locations of scion source (clonal test at Gunungkidul, progeny test in Gunungkidul and clonal test in Wonogiri). Each treatment was repeated in 5 replications and each replication consisted of 10 bud grafted seedlings. The result showed that there were significant variations of growth among the clones in all observation characters, whereas the location of scion source was not significant. The best survival percentage of bud grafting from 3 sites of scion source were Clone 8 from the clonal test in Gunungkidul, Clone 64 from progeny test in Gunungkidul, Clone 43 and 87 from the clonal test in Wonogiri.

Abstract

Root rot caused by Ganoderma philippii (Bres. & Henn. ex Sacc.) Bres., is an important disease in Acacia plantation. A strategy to control this disease is currently being developed, particularly on the application of biological control agent (BCA). Species specific primers for rapid identification of potential fungi as BCA were developed. This study aimed to obtain the best DNA condition and the best primers for species specific identification. DNA with 20x dilution is the best condition for amplification of the ITS fragment thus used for rapid species identification. The best primer set to detect Cerrena sp. is CrF1/CrR1, PbF2/PbR2 is the best primer set for Phlebiopsis sp. 1. There was no specific primer suitable to detect Phlebia sp. 1 and Phlebia sp. 2 only but Pl-2F1/Pl-2R4 is the best primer set for Phlebia spp.

Abstract

Sandalwood (Santalum album Linn.) is a tree which has a high rate of natural sprouting ability. Eventhough the propagation by the conventional techniques (shoot and root cuttings) and by the tissue culture have been reported, the percentage of plants regeneration is still low. The propagation using somatic embryogenesis was reported as better result than using shoots multiplication technique or organogenesis. The objective of this research is to examine the effect of clones, type and concentration of plant growth regulator on the development embryogenic callus of sandalwood. The three tested clones are C1, C2, and C3. The plant growth regulators are 2.4-D, Dicamba, and Picloram with the three level of concentrations:1 mg/L, 3 mg/L, and 5 mg/L. The result of study showed that the clone of C3 performed best on embryogenic callus development. It was observed through morphological analysis that 58.12% of explants performed embryogenic callus with friable texture and white, yellowish in colours. However, there were not significant differences between the types of plant growth regulator, the level of concentrations and their interactions on embryogenic callus development of sandalwood

Abstract

Suren (Toona sinensis) is a potential multipurpose species that is more cultivated at upland community forests, especially in Java and Sumatra islands. This research was aimed to assess the variation of fruit and seed morpho-physiological characters and to investigate the contribution of geoclimate and genetic factors on the fruit and seed morpho-physiological characters of suren. Seeds were collected from seven populations in West Sumatera, Jambi and West Java on March – May 2015. Morphological parameters measured were size and weight of fruits and seeds, while the physiological parameters measured were seed germination and storability. Analysis of variance revealed significant morpho-physiological differences among populations for all the morpho-physiological parameters studied. Cimalaka population provided the better seed quality compared to seed quality from the other populations, mainly for seed physiological parameters. Most of the parameters was not correlated with geo-climate factors, except for number of empty seed that negatively correlated with mean annual temperature and seed wing width negatively correlated with altitude. Genotypic variance and genotypic coefficient of variance for all fruit and seed parameters were found to be higher than corresponding environment variance and environment coefficient of variance, indicating that the genotype explained most of the variance for these parameters. In particular, high heritability values coupled with high genetic gain were found for germination capacity and germination speed. Principal component analysis of various parameters of fruit and seed revealed that most of the geographically distant populations are genetically close.

Abstract

High initial stand density is commonly practiced in forest plantations subjected to produce high quality logs through successive thinnings. In this study, genetically improved seed of Acacia mangium was verified in genetic gain trial using high initial stand density. The trial was established in Jonggol, West Java and laid out in randomized complete block design with high initial stand density of 2500 trees/ha or in spacing of 2 x 2 m. The improved seeds tested in the trial were collected from four seedling seed orchards (SSOs). As a control, unimproved seeds from seed production area (SPA) were also planted together in the trial. The assessment of stand volume productivity was periodically conducted at two, three and four years of age. The results of study showed that the improved seeds from the four SSOs out performed the unimproved one. However, the significant difference among the seed sources was initially found at the four years of age. The average stand volumes of improved seed were 58.56m3/ha, 94.87m3/ha and 163.8m3/ha for two, three, and four years of age, respectively. The superiority of improved seed over the unimproved one ranged from 23%-36% (two years), 6%-30% (three years) and 2%-22% (four years). The four SSOs showed different behaviours in response to high stand density. Improved seed from SSOs with higher selection intensity was likely to be more tolerant to high stand density.
