Abstract

Since the regreening project launched by presidential decree in 1976/1977 and the movement of National Land Forest Rehabilitation (GNRHL) in 2003, community forest plantation area is increasing and inclined to be more independent in their plantation management. In Wonogiri district the community forest achieve the total area of 27.433 hectare, spreaded out in 25 subdistricts. Disease on forest plantation is one of factors that causing significant risk and has to be tackled seriously. The odjective is to identify plant disease (particularly on Teak and Acacia) in community forest of Wonogiri district, Central Java. This is a preliminary study to determine further strategy in disease management. The result showed that teak plants were attacked by bacteria of Pseudomonas tectonae (Ralstonia solanacearum). While Acacia were attacked by fungi of Meliola sp., Atelocauda digitata and Oidium sp., the three fungus attacked Acacia are obligate parasitic.

Abstract

Acacia mangium and Acacia auriculiformis seed orchards on the island of Java are associated with a different species of Ganoderma. The importance of G. steyaertanum as a pathogen of forest trees has not been previously highlighted. The aim of this study is to look at the characteristics of the G. steyaertanum which attacks two Acacia seed orchads at Wonogiri Central Java. Activities undertaken are to identify the signs of the G. steyaertanum both in the field and in the laboratory. Characterization of fungi is conventionally done by observing the morphology of signs, such as the shape and color of the fruit body, shape and color of mycelium. Morphological characteristic applied in this study has proved to be effective to identify the pathogen. G. steyaertanum was isolated from fruitbodies of affected trees and pathogenicity tests confirmed Koch’s postulates. Somatic incompatibility tests demonstrated high genetic variability of the pathogen.

Abstract

Calliandra calothyrsus was introduced to Indonesia from Guatemala in 1930s and had been planted widely throughout Indonesia for fuel wood. Genetic diversity within and among population is an important factor for initiating breeding program. Aim in this study was to evaluate genetic structure of C. calothyrsus in Indonesia, to obtain a better understanding of the history of the distribution and efficiency of breeding strategy of this species. Leaf samples were collected in a seedling seed orchard plot from 10 populations. Six RAPD markers consisted of 34 loci were used to analyze genetic diversity and genetic structure. The results showed that genetic diversity was in low to moderate level (mean HE= 0.321). The AMOVA analysis showed that genetic differentiation among geographical sources was significant, also among populations within geographical sources and among individual within populations as well. It was revealed that the 10 populations originated from only two ancestors. The limited number of ancestors resulted low to moderate genetic distances among populations (mean Da=0.070). In conclusion, C. calothyrsus has moderate genetic diversity within population and weak genetic structure among populations. Genetic diversity in population/individual level should be considered as a selection unit in the breeding strategies.

Abstract

Gall rust disease infected Falcataria moluccana plantations, in several locations in East and Central Java. Effort to eradicate the disease using fungicidal treatment not effective at operational scale. One of the techniques to solve the problem is to develop rust resistant genotypes by selecting tolerant individuals in the field. Kediri is the area where the gall rust disease was found with high level invasion therefore the selection was conducted. The research area is a provenance and progeny trial which was established using 6 replications or blocks, each block contained 77 families, (37 families are collected from Candiroto, 20 from Kediri, 15 from Lombok and 5 from Papua). Result from the data analysis found that individuals from several provenances of Waga-waga, Kuaulu; Muai, Wamena; Hubikosi; Muliama Bawah, Asologoima of Papua, Irian Jaya appeared to be more tolerant to the gall rust diseases than others.

Abstract

The study was conducted to investigate the existence of  family × site  interactions observed in  second generation  open-pollinated progeny test  of  Acacia mangium in two locations: Lipatkain, Riau (Sumatra) and  Kenangan, East Kalimantan.  The progeny tests were  established   using  51-55 families  originated  from Oriomo River Papua New Guinea  provenance. There were 31common families tested at the both sites. Growth on both sites was significantly different between families. The average  height  and diameter was 15,9 m and  13,3 cm  respectively at  Kenangan, and  17,0 m and  16,6 cm  respectively at  Lipatkain. Family × site interactions  were  highly significant for height and diameter. The ratio of variance component of interaction to the family variance component (s2fl / s2f ) for  diameter (1,6) and height (1,2) were largerr than  Shelbourne’s  critical value (0,5),    indicating the low   genotypic stability at family level for the both traits  where the  diameter was  more sensitive than height to changing  site conditions. Genetic correlations between the same trait at different sites were low:  0.45 for height  and 0.38 for diameter. The greatest genetic gain and relative efficiency of family selection were generally expected from selecting and planting families in the same site.

Abstract

Melaleuca alternifolia is the main source for Australian tea tree production. Improving oil quality has been attempted by controlled cross pollination between plus trees. The availability of flowers during flowering season is important for control pollination between , therefore the work to  stimulate flowering should be done. The objective of this study was to increase the flora bud production of 24 month cuttings of M. alternifolia by application of growth retardant (paclobutrasol) and exposure to low  temperatures. Results showed that the application of paclobutrazol was not effective to increase the number of floral buds production. Paclobutrazol application effected only some morphological characteristics. Such as reduced height, smaller leaves, and shorter internodes. On the other hand, exposure of shoot cutting to low temperature for 4 months period increased the number of floral buds and paclobutrazol application following exposure to low temperature was then assumed to have been responsible for the floral response..

Abstract

Schima wallichii (DC.) Korth. (puspa) is a native vegetation of Gunung Merapi National Park (GMNP). This species has an important function for soil and water conservation in GMNP area, especially in the area with high slope. Puspa is also one of prioritised species planted in the forest ecosystem restoration project of GMNP after 2010 volcano eruption. Information on genetic diversity and natural regeneration potential of each puspa stand groups is then very essential for the success of forest ecosystem restoration in GMNP. Genetic diversity parameters of puspa is assessed by isozyme analysis, while its natural regeneration is evaluated by vegetation analysis. Selection of samples on stand groups of puspa for genetic diversity and natural regeneration analysis is based on levels of vegetation damage (low and moderate) and the planting plots of ecosystem restoration area. The results showed that the stands with low damage level located at Gunung Malang and Mriyan have higher genetic diversity than those with moderate damage level (Balerante and Tlogolele). Stand with the highest genetic diversity is Gunung Malang, with the mean observed heterozigosities (Ho) of 0.284 and minimum fixation index value (FIS) of 0.0508. Stand in the Ecosystem Restoration Demonstration Plot has the lowest level of genetic diversity (Ho = 0.1936; FIS = 0.1127). Regarding natural regeneration potential, the stand group of Gunung Malang is the highest.

Abstract

The objectives of this study were to investigate the level of genetic variation and to describe its distribution within and among populations of merbau. Leaves of wildling were collected from four populations distributed in Papua and Moluccas islands. Genetic variation was detected by isoenzyme markers using four enzyme system i.e. Peraxidae (POD), Esterase (EST), Diaphorase (DIA) and Glutamate Oxaloacetate Transaminase (GOT). The result showed that 17 alleles were identified and distributed on 6 polymorphic loci. The mean percentage of polymorphic loci was 95.8 %. The average genetic diversity within population was 0.049. The UPGMA cluster analysis based on Nei’s standard genetic distance reflected three clusters, i.e. Haltim and Waigo formed first cluster, Nabire formed second cluster, and Seram formed third cluster separated from two other clusters.
