Abstract

Herbaceous plants are able to flower any time, give them opportunity to interact with insects. This study aimed to analyze the diversity of pollen collected by Trigona sp. in herbaceous ecosystem and counted the percentage of pollen viability from the pollen basket. Trigona’s nest was adapted at plot and the herbaceous plants with their pollen were identified. Pollen were took from hind legs at 07.00, 08.00 and 09.00 am. Pollen slide were make by acetolysis and SEM methods. Pollen were identified and examined of viability. Identification herbaceous plants and their pollen on plot showed that there were 7 herbaceous plants: Kyllinga monocephala, Cleome rutidosperma, Pennisetum polystachyon, Ageratum conyzoides, Brachiaria mutica, Cyperus orodatus, and Eleutheranthera ruderalis. Otherwise pollen which were collected by Trigona sp. consist of 11 kinds of pollen from 6 families, that were Sapindaceae, Leguminoceae, Loranthaceae, Malvaceae, Symplocaceae, and unidentified family.Viability of pollen ranged from 88.8% to 99.8%. The result of identification herbacious plants and pollen that were taken by Trigona sp. indicated that there was not similarity therefore, it was no interaction between herbaceous plants in the plot with Trigona sp.

Abstract

Aquilaria crassna is one of the Aquilaria species that could produce agarwood. agarwood production of A. crassna can be induced by microfungi as an inoculant. Ecological interaction between the host plant, wounding and inoculant in the formation of agarwood has not yet clearly. other factors like the plant ages, plant species, environ- ment also played important roles in the formation of agarwood. This research aimed to determine the influence of the combination between planting media and Acremonium sp. and Fusarium sp. to agarwood quality of Aquilaria crassna. The experiment was consisted of two factors, which were five planting media and two inoculants fungi i.e. Acremonium sp. and Fusarium sp. The observed parameters were the percentage of senescence leaves, color of wood, level of fragrant and terpenoid content. The best agarwood fragrant was produced by the seedlings that were treated with either combination of husk charcoal media enriched with NPK fertilizer and Acremonium sp. or the combina- tion between husk charcoal media enriched with Hoagland modified solution and Fusarium sp.. The darkest color of wood was produced by the seedlings that were treated with combination of husk charcoal media enriched with NPK fertilizer and Acremonium sp., as well as for the same media with Fusarium sp.. during the experiment terpenoid could not be detected from the treated seedlings. Acremonium sp. caused more leave senescence than that of Fusarium sp..

Abstract

Galangal is widely cultivated for the multifunctional plant. This study analyzed the essential oil chemical components, metabolite profiles, and idioblast cell densities in seven galangal accession grown at two different altitudes (locations A and B). The galangal accessions included: Purbalingga, Cilacap, Purworejo, Karanganyar, Pacitan, Madiun, and Galesia 2 which was used as the control. The results showed that the highest essential oil content was obtained from MAD (3.22%) at location A. The highest levels of ethyl-p-methoxycinnamate (EPMC) were obtained from PBG (74.8%) at location B and PCT (71.6%) at location A. The metabolite profiles of the galangal rhizomes were divided into two clusters based on the metabolite content. The first cluster had one accession: PCT from location A with genkwanin as the metabolite marker. The second cluster consisted of CLP from location A and PBG, MAD, and GAL2 from location B. The highest density of idioblast cells was found in PCT (90.5 cells/mm2) at location A and PBG accessions (77.1 cells/mm2) at location B. The PBG and PCT accessions can be recommended as a candidate of superior varieties based on their high EPMC content.

Abstract

West Indian arrowroot (Maranta arundinacea L.) is a tuber crop that is consumed as an alternative food. İt can grow in an area with altitudinal range from 0 to 1,000 m asl. This study aimed to analyse physiological response and photosynthate distribution which is related to growth performance and tuber yield of West Indian arrowroot at two different altitudes. Four accessions of West Indian arrowroot i.e. Bantul, Krajan, Kemalang, and Begawat were planted at 250 and 1,100 m asl. This study was conducted using split plot design with altitude as the main plot and the accession of West Indian arrowroot as a subplot. The results showed that altitudes significantly affected physiological response, plant height, leaf area per plant, and tuber yield of West Indian arrowroot. The rate of photosynthesis in the highland tended to be higher than that in the lowland, but plant height and tuber yield were lower in highland. These results suggested that the West Indian arrowroot had different pattern on photosynthate distribution between shoot and tuber at different altitudes because of environmental factors. Bantul accession had the lowest tuber yield compared to the others, and showed the low ability of accession Bantul in distributing photosynthate towards tuber.

Abstract

Kedelai (Glycine max) merupakan salah satu tanaman pangan yang dibudidayakan. Kebutuhan kedelai yang selalu meningkat setiap tahun mendorong usaha peningkatan terhadap produksi kedelai. Upaya peningkatan produksi dapat dilakukan dengan menggunakan pupuk hayati dan memanfaatkan lahan yang kurang produktif di Indonesia. Pupuk hayati yang digunakan mengandung isolat Bradyrhizobium japonicum sebagai penambat nitrogen dan Aeromonas salmonicida sebagai pelarut fosfat. Isolat yang terdapat dalam pupuk hayati diharapkan dapat membantu pertumbuhan kedelai di tanah asam dengan menyediakan unsur nitrogen dan fosfat. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati yang terdiri atas B. japonicum (BJ 11 wt) dan A. salmonicida pada penanaman kedelai di tanah asam. Tanaman percobaan dibuat dalam empat kelompok, yaitu dengan inokulasi Isolat BJ 11 (wt), PP, BJ 11 ditambah dengan PP, dan tanpa inokulasi (kontrol). Hasil penelitian menunjukkan bahwa aplikasi B. japonicum dan A. salmonicida cenderung dapat meningkatkan laju pertumbuhan tanaman, jumlah daun, dan bobot kering akar. Kata Kunci: Bradyrhizobium japonicum, Aeromonas salmonicid, Tanah Masam dan Kedelai Soybean (Glycine max) is one of cultivated food crops. Since the need of soybean is always increased every year, it needs some efforts to improve soybean production. One of the steps can be done is by using biofertilizer in a less productive land such as acid soil. Biofertilizer that used in this study consist of Bradyrhizobium japonicum as nitrogen fixation and Aeromonas salmonicida as phosphate solubilizer bacteria (PP). Isolates contained in the biological fertilizer is expected to help the growth of soybean in acid soils by providing elements of nitrogen and phosphate. The aim of this research was to know the effect of using biofertilizer consisted of B. japonicum (BJ 11 wt) and A. salmonicida (PP) to soybean growth in acid soils. The experiment was arranged with four group treatments that were inoculation with BJ 11 (wt), PP, BJ 11 plus PP, and without inoculation (as control). The results showed that the application of B. japonicum and A. salmonicida as inoculant mixture tend to increase plant growth, leaf number, and dry root weight.

Abstract

Tristaniopsis merguensis (pelawan tree) is a potential plant, however, it has not cultivated and conserved optimally due to slow growth and lack of information about the cultivation. The existence of T. merguensis in the forest is important because pelawan fungi grow under the tree, particularly in the above of the roots. Information about how to grow the T. merguensis seedling is very limited; therefore, research in growth and development of T. merguensis seedling was important. The aims of this study were to determine the appropriate planting medium for T. merguensis seed germination and to stimulate growth and development of T. merguensis seedling by using its fungi. Status of T. merguensis fungi was studied by analyzing root morphology. Fungi isolation was carried out from colonized root and fungi fruit body. The stimulated the growth of T. merguensis seedling was done by using fungi isolated from colonization root in laboratory scale, as well as treated at a different phosphate concentration. The result showed that T. merguensis was associated with ectomycorrhizal fungi. Planting medium consists of sawdust and T. merguensis fine root resulted the highest percentage of germination. Seedlings were treated with ectomycorrhizal fungi grew better than without ectomycorrhizal fungi. In addition, seedlings treatment with ectomycorrhizal fungi and phosphate 25% showed the highest growth rate.

Abstract

The accession of mulberry (Morus sp.) with salinity tolerance unavailable in Indonesia is needed to overcome the problem of marginal land, especially in the saline areas of the country. Therefore, this research aims to determine the accession of salinity tolerance of mulberry from 6 origins in Indonesia based on growth and physiological parameters. The method used was a factorial randomized block design with the first treatment of stem cutting-derived mulberry accession being M1, M2, M3, M4, M5, M6, and M7, while the second was the concentration of NaCl at 0 mM, 40 mM, 60 mM, and 80 mM. The results showed that M2 accession from Bogor was categorized as tolerance to high salt stress, and M1 was classified as sensitive accession. Increasing salt concentration causes a decrease in growth parameters. It also decreased physiological parameters such as leaf and media relative water content while increasing dissolved sugars. Genotypic scores indicate salinity tolerance and the potential number of leaves, while Na+ content and leaf necrosis percentage showed sodium toxicity in the leaf. Therefore, genotypic score, Na+/K+ ratio, and leaf necrosis percentage are the best parameters to select and identify mulberry accession with high salt stress tolerance.

Abstract

Aquilaria malaccensis is agarwood producing species in Indonesia. Agarwood compounds are formed as a chemical response of Aquliaria malaccensis tree to various physical damages, phatogen infection, or chemical treatment. Factors influencing agarwood formation are age of the tree, season, geographical location, environment, and treatment period. Agarwood induction may be done in tree or sapling. Agarwood induction in saplings need more effort than in trees. Combination of fungi (Fusarium solani) and nutrient (Nitrogen fertilizer) treatment may be one way to induce agarwood in A. malaccensis saplings. This study aims to produce A. malaccensis agarwood (aromatic compounds and colour) by induction of F. solani and nitrogen fertilizer, and analyse the agarwood chemical content. The agarwood chemical content was investigated by Gas Chromatography Mass Spectrometry (GCMS) analysis. Results indicated that agarwood had a different colour for every treatment. The darkest brown and most fragrant agarwood were produced by A. malaccensis treated by a combination of nitrogen fertilizer (4 gr/sapling) and F. solani inoculation. Three chemical compounds were identified i.e. silanediol dimethyl, 4-ethyl benzoic acid and 1,4,7,10,13,16- hexaoxacyclooctadecane with percentages of 25.7, 17.62, and 3.56 respectively. A. malaccensis treated by nitrogen fertilizer and F. solani for 3 months is able to induce aromatic compounds formation, but the colour still dark brown. Biosynthesis of aromatic compounds in agarwood occurs first before changes in the colour of the wood.

Abstract

Oil palm has been widely studied regarding growth and development, water use, productivity, and other economically relevant functions. However, not much is known about the hydraulic conductivity of oil palm root systems and how xylem vessels perform their function to transport water from roots to shoots so far. This information is needed to describe oil palm strategies to maintain water status, especially in oil palms that grow under various soil hydrological regimes. To investigate the root hydraulic performance, we measured mean xylem vessel diameter (D), vessel density (VD), vessel lumen area (Alumen), and potential hydraulic conductivity (Kp) for oil palm root samples in seasonally flooded riparian and well-drained sites at Harapan Jambi Forest. The result showed that D, Alumen, and Kp increased with increasing root diameter at both plantation types. On the contrary, VD significantly decreased with increasing root diameter. Potential hydraulic conductivity (Kp) in riparian sites was smaller than in well-drained sites and significantly different in root diameter >2-5 and >5-10 mm and related to both plantation types. The low potential hydraulic conductivity of root xylem vessels and the narrowing of xylem vessel lumen that occurs in oil palm roots in the seasonally flooded riparian sites were presumed as adaptation mechanisms to maintain water supply from the roots to the shoot in oil palm plants in these sites.

Abstract

Rhizome with high productivity and content of bioactive ingredients is the hope to be achieved from the cultivation of galanga (Kaempferia galanga L.). Galanga is used traditionally as a medicine for stomach ulcers, colds, headaches, coughs, diarrhea, facilitating menstruation, skin diseases, and rheumatism. Production of secondary metabolites is influenced by environmental factors and the place of growth. This study aims to determine the effect of the growing environment from two different locations on the essential oil content and its constituent components from the rhizome of the galanga accessions. The samples observed were nine accessions of galanga harvested at 6 months which were planted in the Bogor, namely Darmaga (L1) and Cisarua (L2) with a altitudes of 214 m asl and 780 m asl with different agro-climatic conditions. The accessions tested included Purbalingga (PBG), Cilacap (CLP), Purworejo (PWJ), Karanganyar (KRA), Pacitan (PCT), Madiun (MAD), Galesia 1 (GAL 1), Galesia 2 (GAL 2), and Galesia 3 (GAL 3). GAL 1, GAL 2, and GAL 3 are high yielding varieties of galanga that have been released by the Minister of Agriculture of the Republic of Indonesia and used as comparisons based on their essential oil content. Observations were made on the levels of essential oils and their constituent compounds using GC-MS (Gas Chomatography-Mass Spectroscopy). Differences in growing places affect the content of essential oils and their constituent components from the rhizome of the galanga accession. Environmental factors that influence are sunlight and water availability. The highest essential oil content (3.78%) was obtained from the MAD accession planted in Cisarua (L2) and the highest EPMS compound (34.74%) was obtained from the PCT accession planted in Darmaga (L1). There were 73 compounds detected with four main components, namely delta-3-carene, pentadecane, ethyl cinnamate, and ethyl p-methoxy cinnamate (EPMS).
