Abstract

Charcoal, or black coloured carbon-predominated stuff, is produced during incomplete combustion of  woody plant biomass. Charcoal application to the soil can improve chemical and nutritional nature thereby inducing better plant growth and development. However, the utilization of charcoal in forestry sector, especially industrial plantation, has not been introduced due to the absence of available information.  Indicator species used in this study are Acacia mangium and Michelia montana. A. mangium is one of  the most important species grown in industrial plantations in Indonesia. Meanwhile M. montana is critical endemic species in Gunung Halimun National Park. Glasshouse research was designed to examine the effectiveness of charcoal incorporation into marginal soils on the growth of 6-month-old Acacia mangium and 6-month-old Michelia montana. Charcoal treatments were 0,10, 15 and 20% (v/v) for A. mangium, while 0, 5, 10, 15 and 20 % (v/v) for M. montana. Representative samples of Orthic Acrisol (i.e. Very fine, mixed, semiactive, isohyperthermic, and Typic Paleudult) were collected from B horizon. A completely randomized design with four replications (for A. mangium) and five replications (for M. montana) was employed to examine the effect of charcoal application on the plant growth and some important chemical properties of  the corresponding soil. Charcoal additions to the soil significantly increased height, diameter, and leaf and stem biomass weight of A. mangium, and significantly increased height, diameter, and total biomass weight of  M. montana seedlings in comparison to those of a control.  Increasing the amount of charcoal higher than 10% level, however, have little effect on A. mangium growth. On the other hand, increasing the amount of charcoal higher than 10% is still effective on M. montana growth. This study indicated that charcoal application at the rates of 10 % for A. mangium and 15 % for M. montana would be adequate to improve the availability of soil nutrients, and hence significantly induce a better plant growth response.

Abstract

Salinity effects on plant can often be related to mineral ion content alteration, including phosphate. Under saline conditions, phosphate levels were reported to decrease in plants. Such effects could indirectly affect intracellular phosphate levels, leading to phosphate deficiency, which in turn leads to increased activities of phosphate uptake mechanisms. This research was aimed to investigate the effects of salinity on the expression changes of phosphate transporter genes isolated from E. camaldulensis x E. globulus hybrid clones subjected to salt concentrations of  0 (control), 50, 100, and 150 mMNaCl. Fragments of genes (1164bp long and encodes 304 amino acid polypeptides) known to be involved in phosphate uptake were identified and isolated by RACE from these hybrids, encoding a Phosphate Transporter (Ecg PT). Expression studies using Northern-Blot analysis revealed that the expression of EcgPT was found to be affected by salt, suggesting a direct effect of salinity on phosphate uptake. EcgPT was expressed differently in different clones, indicating different degrees of phosphate transporter activation in order to tolerate salt stress. Molecular data are discussed in relation to measurements of ion levels in different organs of different clones and under various salt regimes during the course of the hydroponic experiment.

Abstract

Development of  meranti (S.leprosula) plantation forest is limited/ constrained by many factors, e.g.   seed supply and seedling growth environment. The research deals  with the observation of  the current condition on A.  mangium  stand and did not  employ any treatments.  Meranti seedling was obtained from vegetative cutting (Komatsu-Forda), at one year (old) post planted meranti under A. mangium stands  and spacing of 4 x 2 m, approximately two hectares of permanent  sample plot (PSP) were made. Ineach hectare  of young meranti plants with spacing 10  x 3 m  (330 seedling/ha),  9 (nine) observation plots  with size 10 x 10 m (6 seedlings/plot)  were prepared,  and placed in the middle of PSP. Totally, there were 108 seedlings available for the measurement of particular parameter, i.e. light intensity, height growth, and survival rate. Light intensity  was  measured by going around of 10 x 10 m plot.Result of measurement in each observation plot (10 x 10 m size) rescaled that light intensity ranged about  6,55  - 35,2% or being equal with 4908 - 26568 flux hour. Meanwhile, the best height growth response and survivalrate were at 10 %   light intensity or over.

Abstract

Indonesias forests have economic, social, and environmental benefits. Some national efforts, as well as support from the global community for sustaining forest development in Indonesia have been done. However, some problems were still reported during the implementation of the forest development. Thorough analysis was needed to formulate the root of the problems, and to identify solutions/supports to the current forest development to achieve its sustainability. Descriptive analysis was used in this study. The results indicated that sustainable forest development in Indonesia was still faced with the problems of uncertainty of management, insufficient management capacity, and lack of law enforcement. These conditions were indicated by high conflict of interests as well as lack of support from stakeholders, not enough forest management actions at site-level, and high forest degradation. Aiming at overcoming problems of sustainable forest development and maintaining sustainability of Indonesias forest, national forest management needs to embrace more space for communication, openness, mutual learning, collaboration in addressing forest conflicts, and determining the future direction of its sustainability goal of management.

Abstract

Photosynthetic responses associated with initial stages of root-rot disease have been studied through setting up an artificial inoculation of Eucalyptus nitens trees with a root-rot pathogen, Armillaria luteobubalina. Trees were inoculated with two different strains of A. luteobubalina. Root systems were either wounded or left intact before inoculation. Three photosynthetic parameters, i.e. photosystem II yield (Fv/Fm), chlorophyll content and photosynthetic rate (Amax) were assessed during six-months of observation. Photosystem II yield was the most sensitive to root-rot infection. A significant difference in Fv/Fm between the unwounded control (UW-P0) and other treatments was observed, and the difference  was  affected by interaction between time and treatment factors (F- ratio = 3.798, p-value = 0.005).  Chlorophyll content and photosynthetic rate (Amax) decreased for all trees, including controls, during the period of the experiment. The decrease was more marked in treated than control trees, and the changes more determined by the time factor  (p-value <0.0001). The root systems of inoculated trees were examined and re-isolations of A. luteobubalina from symptomatic roots were carried out to confirm infection with A.luteobubalina of E. nitens trees. This preliminary trial was successful and did indicate that there were detectable physiological changes associated with early infection of root-rot. However the experiment required a longer duration for more widespread physiological changes to be detected.

Abstract

Under  Pinus radiata plantations  where  the tree spacing  is wider  and most soils are phosphorus  (P) deficient,  the radiata  tree response to P fertilizer is expected  to be more influenced  by  the interaction between  the applied  P fertilizer, the tree and understorey vegetation.  Therefore,  a better understanding of the soil P chemistry under radiata pine trees in association  with  other  plants  is required.  We investigated  the effect of broom  (Cytisus scoparius L.) and ryegrass  (Lolium multiflorum) grown  with  radiata  seedlings  in Orthic Allophanic Soil treated with  0, 50, and 100 μg P g-1  soil of TSP on the pH and phosphatase activity in the rhizosphere soils under glasshouse condition. The pHs of radiata rhizosphere soils either grown with broom or grass were lower than  those in the  bulk soils and the bulk and rhizosphere soils of grass and broom,  whether  they  were grown  alone or grown  with radiata at the  applications of 50 and 100 μg P g-1 soil. These results suggest that P application enhanced root induced acidification  in a P-deficient Allophanic Soil under radiata.  The soils in the rhizosphere of grass and broom, grown in association with radiata, were also acidified by  the effect of radiata  roots.  Acid  phosphatase  activity in soils under  radiata,  grass and broom  decreased with  an increased  rate of P application. At all P rates,  acid phosphatase activity was higher in the rhizosphere of radiata  grown  with  broom than in the bulk soils. The phosphatase activity in the rhizosphere soil of radiata grown with broom was also higher than that of radiata grown with grass, but it was slightly lower than that in the rhizosphere of broom grown  alone. These results suggest that broom may have also contributed to the higher  phosphatase  activity in the rhizosphere soils than  in the bulk  soils of broom  and radiata when they were grown  together

Abstract

Shoreapinanga Scheff.   is a major tropical plant species which has an important  economic  value not  only for timber,  but also as illipe nut  (called tengkawang  in local  name) production.   This species   is suggested   for  land  rehabilitation    and  forest  conservation.    In rehabilitation   action, S. pi11a11ga is usually   planted   on the poor  and degraded  area.   Application   of  chemical  fertilizer and compost  is used to increase  the survival  and growth  of  the  seedlings.  Excessive chemical fertilizer  input  to soil, however,  may cause  negative  effect on  soil,  plant  and  environment. Conversely,  compost  may improve soil porosity, soil aggregate,  water absorption   and soil fertility. The objective  of  the study  was  to examine  effect  of  planting  media  on growth  of  S. pinanga  seedlings. Complete  randomized  design has been arranged with 5 treatments,  e.g. soil mixed with husk  (at the proportion   of  1:1), soil mixed with acacia compost  (1:1),   soil mixed with charcoal of  rice husk (1:1)   and soil mixed with humic acid (1:1).    Another  treatment  was  soil alone  used as control.   The  result showed that  growth  of  both  stem  height   and  diameter,  and  index  of seedling  quality  were affected  significantly   by planting  media.    The mixture  of  soil and  acacia compost  (1 :1)  was the best  planting media for the growth  of S. pinanga seedlings,  which resulted in the growth  of height  (24.19   cm) and stem diameter  (0.246 cm).  Meanwhile, soil mixed with rice husk charcoal (1:1)  gave the best result to the index of  seedling quality (ISQ = 1.34)   and total dry weight (TOW=   15.93  g).

Abstract

Phenolic is well known as a secondary metabolite that plays an important role in plant defense system. Information about the fungi-impeded role of secondary metabolite is important in achieving success of artificial agarwood production, in that fungi induction imparted to the selected potential trees will be more effective and efficient. This research was aimed to investigate the correlation of agarwood tree phenolics in relation with the susceptibility of corresponding trees to Fusarium solani attack in the formation of agarwood and observing total phenolics content of Aquilaria crassna and Aquilaria microcarpa trees prior to inoculation. Twenty trees of A. microcarpa at Carita, a Forest Area for Special Function (FASF) and ten of A. crassna at Dramaga Research Forest were inoculated with isolate of F. solani in spiral pattern around their stem from ground level to about 1.5 m in height. Prior to inoculation, wood strips were taken off from the stem for total phenolics content. The result revealed that total phenolics content and infection area tended to have a negative correlation. Since the quantity of agarwood is highly related with the infection area, then trees with lower phenolics content should be selected for the more effective and efficient artificial agarwood production.

Abstract

It is not easy to define color because it refers to psychological response of human. As a result, perception of color achieved by people is relatively different.  Wood color plays an important role in timber processing and it is an important consideration in wood identification. Each wood species has specific color and it becomes the species characteristic. Colors in wood are highly variable and unique features. Characteristics of wood color are influenced by extractive materials and moisture contents present on it. A standard of color measurement has been developed and it is called CIE model. The standard was developed to be completely independent of any devices and was based as closely as possible on human observation in color. CIELAB system is one of the simplest and most practical color measurement methods. The system has been used in one of the color measurement devices developed by Data Color International that is Microflash-200®. This research was aimed at translating interpretation of wood color by human eye into mathematical values so that scientific measurement of wood color can be studied. The measured wood color were 10 species of pines and 10 species of eucalypts woods in dry condition. The results showed that the two groups had different average of L*, a* and b* values. The average of L* for pine was 70.77, while eucalypt group made up to 52.40. It means that eucalypt group is darker than pine group. For a* value, pine group mean value is 20.23, whereas eucalypt group touches 19.11. In other words, pine and eucalypt group have an approximately similar redness. The b* value average for pine and eucalypt groups are 43.40 and 29.07, respectively. This value means that pine group is more yellow than eucalypt group.

Abstract

This paper provided information regarding artificial agar wood production. Fungi are considered as biological agent for agarwood formation and agarwood is assumed as tree defense mechanism product. This research was aimed at investigating the anti fungal activity (AFA) of Aquilaria crassna, one of the agar wood-producing trees, against Fusarium solani in vitro. Aquilaria crassna wood mill was extracted by 70% ethanol to investigate the anti fungal activity. The result are Aquilariacrassnaexhibited low extractives content, which was only 2.0% (w/w) and a low anti fungal activity in vitro, especially for ethanol extract. However, further fractionation and bioassay showed that the most active component was likely in the ethyl-acetate soluble fraction that exhibited strong anti fungal activity (52.5%) at 4.0% of concentration.
