Abstract

Screening primer is an effective method to develop microsatellite markers from related taxa. Aim of this study was to develop microsatellite markers of four Shorea producing tengkawang oil, i.e. Shorea gysbertiana, Shorea macrophylla, Shorea pinanga and Shorea stenoptera by screening microsatellite primers of Shorea curtisii. Leaf samples of the four Shorea were collected from nursery at Center for Forest Biotechnology and Tree Improvement Research in Yogyakarta. Four microsatellite primers of S. curtisii i.e. Shc-1, Shc-2, Shc-7 and Shc-9 had been used to screen. Results showed that numerous alleles were shared among the Shorea. The expected heterozygosity (HE) for locus Shc-1 ranged between 0.594 and 0.722; locus Shc-2 ranged between 0.219 and 0.611; locus Shc-7 ranged between 0.594 and 0.778; and locus Shc-9 ranged between 0.594 and 0.844. Coefficient of inbreeding (FIS) value was low and it was insignificant deviated from Hardy-Weinberg Equilibrium (HWE) at  almost all loci except Shc-1 of S.  pinanga. A dendrogram showed two clusters; S. gysbertsiana and S. macrophylla represented in one cluster, while S. pinanga and S. stenoptera represented in another cluster. Therefore the developed microsatellite markers are possible to be applied for studying population genetics and mating system of these species.

Abstract

The most seriouse affecting Sengon (Sengon (Falcataria moluccana) plantation is Gall rust is coused by the fungus Uromycladium tepperianum (Sacc.) McAlp. This disease reduced the yield due to mortality and stems brakage (fllowing the formation of stem-girdling galls) reduced marketability and  decreased of ghrowth rates. This research aimed to select seedlings sengon which is tolerant to gall rust disease at provenence level, Five seed sources were used for this study i.e. from Papua (Elaigama Hubikosi and Siba Hubikosi) and Java (Candiroto, Kediri and Wonosobo). Inoculation was carried using fresh spora of Uromycladium tepperianum, There times when the seedlingreaches two weeks old. Then obsevation has been done for height and symptom scoring for evaluating disease incidence and severity. The result showed there were variations for height, disease incidence and disease severity. Seedlings sengon from Papua exhibited growth (height) about 6,5-12,2 cm,  and seedlings from Java. It recorded that seedlings from Papua exhibited 0% of disease incidence ansd disease severity, meanwhile seedling from java is more susceptible to the gall rust, by which exhibited hight value of disease incidence (86-94 %0 and disease severity (53-60%).

Abstract

In tree improvement program, vegetative propagules, including grafting, from improved materials will develop into individuals with the same genetic structures from its improved clonal sources. Vegetative propagules are also advantagous due to their earlier flowering and fruiting if compared to seedlings. Grafting success will be etermined by compatibilities between 2 different tissues from different genetic sources. In this study, grafting success of E. occidentalis between rootstocks and entries of different provenans and families were examined using scions collected from mature (6.5 year) trees to hasten deployment of improved genotypes. Reciprocal grafting between provenances with different provenance  rootstocks and scions were conducted with successvaried from none to complete survival. Abilities of two best provenans under waterlogging, Dumbleyung and Young River, to perform highest survival in grafting provide advantages for deployment of their genetic materials. Genotype differences between scions were more obvious to influence survival than between rootstocks. Small number of grafted plants initiated flowers 4 months after grafting. Scion diameter, length and initial leaves affect the growth of new shoots. The best E. occidentalis grafting success were determined by scion length of 2.5 - 4 cm, diameter of 6 - 7 mm with all leaves removed.

Abstract

An open-pollinated progeny test of Araucaria cunninghamii was established in Bodowoso, East Java.The seeds were collected from 28 parent trees in 3 provenances in papua. The progeny test was arranged according to randomized Complete Block Design consisting of 28 families, 8 replications, 4 lines tree plot and spacing at 4 m x 3 m. At five years of age differences between provenances or families within provenance was significant for height, diameter and stem straightness. Heritability estimates for height, diameter and stem straightness were all moderate: (h2f – 0.44, h2i =0.11) for  height, h2f – 0,36 h2i =0.12) for straightness). The genetic corrwelations between traits were strong and positive: 0.62 for height and diameter, 0.73 for diameter and straightness (rg=0.73) and height and straightness. The genetic gains from family selection with  selection intensity of 70 % for height, diameter and stem straightness were 7.8 %, 2.5 %, and 9.7 % respectively, While those from individual selection with selection intensity of 10 % for height, diameter and stem straightness were 10.7 %, 4.6 % and 15.3 % respectively.

Abstract

The availability of source material to multifunctional tree Toona sp. have constraints for macro and micro propagation, in this regard, this study aims to:1)observe the formation of buds on T. sinensis and T. sureni stem cuttings in an effort to sustain the availability of explants and 2)analyze the effect of GA4, IBA and BAP growth hormone on regeneration and propagation of the axillary bud initiation and callogenesis through tissue culture. Isolation of stem cuttings was conducted in a greenhouse with number of shoots per nodule and nodule distance as observed.Variables Tissue culture techniques were used to study the effect of exogenous GA4 hormones application on the initiation of axillary buds. The application of IBA hormone on plantlet rooting and callogenesis. The results showed that T. sinensis has 2-7 buds per nodule and nodule distance of 2-5 mm, while T. sureni has one bud per nodule and nodule distance of 5-10 cm. The average length of T. sinensis shoots were 15.8 cm and 17.4 for T. sureni. Enrichment with 1 mg/l GA4 gave the highest axillary shoot length on T. sinensis (8.5 cm ± 0.7228) and (9.8 cm ± 0.1022) for T. sureni. Two mg/l IBA enrichment gave the highest root length of T. sinensis (10.9 cm ± 1.8392) and for T. sureni (7.9 cm ± 0.7633). Three mg/l concentration BAP application gave the best effect in term of callus weight of T. sinensis (1.4 g ± 0.3833). Scoring of callus weight showed moderate response categories to both T. sinensis and T. sureni.

Abstract

Clonal materials are often collected for testing under extreme condition. Clonal production through mass vegegetative propagation is also common for deployment of improved genotype. Root development of clones compared to that of seedlings will further determine the subsequent growth. Eucalyptus occidentalis ability to grow under extreme conditions (waterlongging and/or salinity) drives the importance of provenance and family selection from materials collected throughout its natural distribution. Performance of clone and seedling under waterlogging and salt  waterlogging conditions of two E. occidentalis families, high and low salt tolerant, were investigated. Seedling (4.5 months) and cutting/clones (5.5 months) were exposed to control, waterlogged and salt waterlogged conditions reaching to sea salt level (500 mM Nacl). Seeding and cutting performances were determined by ability of plant type and family to produce roots and consequently initial leaves to support their growth. Seedlings and cutting of high torelant family 153-Red Lake perform better than low tolerant family 96 Lake Magenta under high level of salinity. Under high salt concentration, seedling are better than cutting for family 153- Red Lake, but both plant types perform similiarly for family 96-Lake Magenta. Sanility hinders shoot and root development. Under inundation, E. occidentalis tends to decrease shoots rather than roots. For clonal growth improvement, propagation method to produce root abundance is necessary.

Abstract

Nyamplung (Callophylum inophyllum L.) and johar (Cassia florida Vahl.) are alternative plants that are resistant to drought. Global warming that occurred in the last few years caused extreme climate change, one of which is drought. The purpose of this research were to examine and determine the growth and development of plants and the response of morphology, physiology, and anatomy of these plants to drought condition, and adaptive species to drought. This research used drought stress treatment for 10 days, 20 days, 30 days, and 40 days, while control plants were watered every 2 days. Each treatment used 3 replications. Parameters observed were plant height, stem diameter, number of leaves, leaf area, proline levels, plant water content, total dry weight, root dry weight, stomata index, root anatomy, anatomy of stem, and leaf anatomy. Physiological data obtained were analyzed using T-test. The results showed that plants responded to drought stress by decreasing plant height, stem diameter, number of leaves, leaf area, root dry weight, total dry weight, water content of plants, transpiration rate, stomata lindex, root cortex thickness, leaf mesophyll thickness, leaf phloem thickness, other wise occurred increasing level of proline, root epidermis thickness, stem xylem diameter, stem cortical thickness and leaf xylem thickness. Johar plant was more adaptive plant to drought stress than nyamplung plant.

Abstract

Sandalwood (Santalum album L.), a native plant of Nusa Tenggara Timur, has a very high economic value due to santalol content in the heartwood. Currently the gap between demand and production capability of sandalwood oil is high. Productivity and quality of sandalwood can be increased through a series of tree improvement activities, such as establishing a progeny test to produce genetically improved seed. Balai Penelitian Kehutanan Kupang has established a first generation progeny test of sandalwood at Timor Tengah Utara regency, Nusa Tenggara Timur province to improve the productivity of heartwood, rendemen and santalol contents. The trial was laid out in Incomplete Block Design (IBD) consisting of 65 families, 3 tree-plots, 5 replications with a spacing of 4 x 4 m. This study was aimed to evaluate the growth of sandalwood progeny test at eight months after planting. The result of study showed that average growth of height and diameter are 48.60 cm and 4.55 mm, respectively. The estimates of family and individual heritability for height are 0.06 and 0.03,respectively, while for diameter are 0,16 and 0,10. Genetic correlation between the heightand diameter is 0.87.
