The major pools and turnover rates of the global carbon (C) cycles are presented and compared to the human production of CO2 from the burning of fossil fuels (e.g. coal and oil) and geothermal fuels (natural gases), both categorized as non-renewable energy resources which in amount reaches around 6.5 Gigatons C per year. These pools that serve as C-holding stallions are in the atmosphere, the land plant biomass, the organic soils carbon, the ocean carbon and the lithosphere. In another related case, the present focus in the area of nitrogen fixation is discussed with data on world production of grain legumes compared to cereals production and nitrogen fertilizer use. The focus to understand the molecular biology of the legume-rhizobia symbiosis as a major contributor to nitrogen fixation is in the areas of signal exchange between host plants and rhizobia in the rhizophere including the nod factor signalling, the infection and nodule compartmentation and the soils stress factors affecting the symbiosis. The use of the Legume-Rhizobia symbiosis as a biotest system for soil contaminants includes data for cadmium, arsenate, atrazine, lindane, fluoranthene, phenantrene and acenaphthene and also results on the mechanism, why the symbiotic system is more sensitive than test systems with plant growth parameters.

Regeneration of Imperata grassland areas is becoming increasingly important, both to create new secondary forest and to recover the original biodiversity. The diversity of plant communities in secondary succession of Imperata grasslands was studied using 45 subplots of 9 linear transects (10 m x 100 m). Data was collected and all stems over 10 cm dbh were identified, the Importance Values Index (IVI) for all trees were calculated, saplings and seedlings were counted and analysed, and soil samples were taken and analysed. Results showed that after more than 10 years of regeneration, 65 families were encountered consisting of 164 species, which were dominated by Vernonia arborea Buch.-Ham, Vitex pinnata L., Macaranga gigantea (Reichb.f. & Zoll.) Muell.Arg., Symplocos crassipes C.B. Clarke, Artocarpus odoratissimus Miq., and Bridelia glauca Blume. The effects of regeneration, from Imperata grassland to secondary forest, on soil were the strongest in the A-horizon where an increase in carbon, N content, and pH were observed. Our result shows that Imperata grasslands appear to be permanent because of frequent fires and human interferences and so far few efforts have been made to promote sustainable rehabilitation. If protected from fire and other disturbances, such as shifting cultivation, Imperata grassland will grow and develop into secondary forest.

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.

This paper identifies the plant species used traditionally by Karo people in North Sumatra, to cure diabetes, analyses the cultural significance index of those plants for the Karo, and clarifies phytochemical contents of the plants. Data were collected using survey method from selected respondents (n=54) based on their knowledge and practices in utilising medicinal plants to cure diabetic disease. Index of Cultural Significance (ICS) of plants was determined using the method proposed by Turner. Results showed that twelve woody plant species have been used to cure diabetes: loning leave (Psychotria sp.), kacihe leave (Prunus accuminta Hook), umbrella tree leave (Maesopsis eminii Engl), mutamba leave (Guazuma ulmifolia Lamk), cepcepan leave (Villebrunea subescens Blume), pirdot/cepcepan lembu leave (Saurauia vulcani Korth), raru bark (Cotylelobium melanoxylo), breadfruit leave (Artocarpus altilis), salam leave (Syzygium polyanthum Wight), mahogany seed (Swietenia mahagoni (L.) Jacq), cinnamon bark (Cinnamomum burmani), and yellow bamboo rod (Bambusa vulgaris Schrad). Five of those plants: loning, umbrella tree, mutamba, raru and salam have the highest cultural significance level. These five plants are highly needed in large quatities by the Karo people, so their availability in the forest should be securely conserved and protected. The plants used contained alkaloids, flavonoids, phenolics and terpenoids which can help to lower blood sugar level.

Gamma irradiation of seeds is known as an important factor in stimulating biochemical and physiological processes. This paper investigates the effect of seed irradiation on the seed germination, storability, and seedling growth traits of Magnolia champaca. Seeds were irradiated with 0, 5, 10, 15, 20, 40, 60, 80 and 100 Gy by Cobalt-60. The treated seeds were grouped into three lots, namely germination test, storage test and seedling growth characteristics. Observations were made for seed germination percentage, germination index, mean germination time, germination value and growth traits such as height, collar diameter, number of leaves, root length, and dry weight. Results showed that irradiation at a dose of 30 Gy was close to LD50, and irradiation at doses of 80 Gy and higher caused lethal effect. The maximum increase of germination parameters on irradiated seed was recorded at a dose of 10 Gy, and then it decreased. Growth rate in terms of seedling height, collar diameter, number of leaves, and dry weight have also increased in gamma irradiation doses up to 80 Gy, but the dose of 10 Gy resulted in survival and growth that was more stable and gave the highest values for most of the parameters. Hence, lower dose (10 Gy) of irradiation treatment can be used to increase seed germination, storability and seedling growth of M. champaca.

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.

Family variation of capsule production and the seed viability in the Paliyan full-sib trial of Melaleuca cajuputi subsp. cajuputi, at Gunungkidul, Yogyakarta, were observed. The full-sib trial was designed as Incomplete Block Design, consisting of 39 families; six individual as tree plot and replicated in eight blocks. Height and diameter at breast height were assessed to identify the correlation between capsule category and growth performance. The capsule production was assessed visually to one of the capsule categories: “0” for none; “1” for light; “2” for medium and “3” for heavy. Results showed that each family of M. cajuputi sub sp. cajuputi equally contributed to the seed production. Progeny analysis showed that the seed productions were not strongly under genetic control (h2i) = 0.12. This study also found positive correlation between the flowering strength (the flower production levels) and the number of capsule (R2=0.279). However, there were no significant differences between the flowering levels and the viability of M. cajuputi sub sp. cajuputi. Mean seed viability was 31%, there were no significantly differences of capsules production between trees having high flowering intensity and low flowering intensity. Low seed viability was assumed due to the unsynchronicity of flowering, leading to the low levels of outcrossing rate. Therefore, selection of families with synchronicity of flowering was recommended to establish a seed orchard.

Currently, tropical peatland forests are under considerable pressure because of increasing deforestation and degradation of forests. In Kalimantan, degradation and deforestation of peatland forests are driven primarily by industrial logging, expansion of agricultural activities through primarily conversion of forests to agricultural land and oil palm plantations. By the establishment of intensive drainage, it can induce wildfires in peatland. Unmanaged drainage ditches will alter water table levels within the site adjacent to the drainage including to surrounding peatland forest. Water table assessments were conducted before and after peatland drainage on 2007/2009 and 2012/2015 in Kubu Raya, West Kalimantan. This paper studies the effect of drainage ditches into the peatland water table. Results show the establishment of drainage ditches on this peatland landscape lowered the water table by more than 3 times from ~11.7 cm (SE = 1.5, n = 5) to ~37.3 cm (SE = 2.1 cm, n = 26). The effect on the water table was in drier months of July-August. Lowering the water table level altered worst the soil micro climate, peat temperature and peat water content. The results indicate the land use changes in peatland with the establishment of drainage affects peatland water table currently. In the area of less than 500 m from the drainage, the water level tends to lower toward the drainage feature. Therefore, recovery of peatland forests should be initiated by managing the landscape hydrology (i.e. water table) to restore the ecosystem and to protect the remaining peat swamp forest.

Coconut palm (Cocos nucifera L.) is known as 'multi-purposes tree' as almost all part of the tree can be utilised. Coconut timber utilization is limited on hard or denser part, while lighter coconut timber remains unused. Theoretically, mechanical densification could improve physical properties of light coconut timber, which may be useful for diversifying its uses. This study examined some anatomical changes in coconut wood that occurred during mechanical densification. Coconut wood samples measuring 40 mm thick, 40 mm wide and 50 cm long were steamed at 1260C for 30 minutes prior to being compressed by 23.75 kg/cm2 pressure. Anatomical measures were undertaken using light microscope and scanning electron microscope on both non-compressed and compressed samples. Results showed that the treatment significantly reduced void volume and increased vascular bundles frequency, decreased vessel and parenchyma cell diameter. The wood density also increased by more than 50%.
