This species is widely cultivated in several regions in Indonesia due to the high demand for carpentry timber. Therefore, to meet the high demand of wide leaf mahogany wood, the development of plantation forests of S. macrophylla with high productivity is very much needed. Development of plantation forests with high productivity requires the support of improvement seeds. Therefore, this study was conducted to determine the survival rate, growth variation between land race and between mother trees of 18 months old of S. macrophylla progeny trial. This progeny trial at the end of the selection can be converted into a seedling seed orchard (SSO) to produce the improvement seeds. Incomplete Block Design with two factors, i.e. land race (5 levels) and mother tree (50 levels) was used in this study. The results of the analysis showed that the survival rates of plant was significantly different between the land race but not among the mother trees. The average of survival rate of this species is only 71.58%, due to the landslide during the rainy season, burnt during the dry season and also exposed to stem borer attacks. Growth parameters (height and stem diameter) were significantly different between land race and mother tree. It showed that the Bondowoso land race exhibited the best performance of height and stem diameter, respectively 151.55 cm and 21.97 mm. The best mother tree in terms of growth (height and stem diameter) were exhibited on 19 individual tresses, with a range from 130.38 to 171.64 cm for height character and from 20.46 to 26.47 mm for stem diameter character.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80294752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Innovation to produce renewable energy from easily utilized raw materials should meet society’s needs including renewable raw materials from wood biomass for energy. Genetically improved Calliandra calothyrsus has been developed for this purpose. Due to low success rate of its reproduction, study on its reproductive biology was undertaken. The study was carried out during the flowering seasons of C. calothyrsus, by examining flower morphology, pollen, and pistil viabilities as wee as insect visitors to this species’ flowers. The study showed that the flowers of C. calothyrsus are borne on inflorescences (spikes) and carrying an average of 354 individual flowers, which develop acropetally. Pistils (female organ) cease to develop by the 2 to 3 day after their appearance, and the flowering is becoming ceased then. Pistils showed maturity during the period of 09.00 WIB 10.00 WIB and pollen is still viable from 1 to 3 days after the pollen opening. Three most frequent visitors (families: Apidae, Vespidae, Formicidae) and one order lepidoptera were found visiting C. calothyrsus flowers However, the reproductive success of C. calotyrsus is found to be very low, which is only 0.024. These preliminary results confirmed that the low reproductive success of C. calothyrsus is due to the structure and development of flowers allowing the incidences of both outcrossing and self-pollination. The limitation time of pistil maturity might also contribute to the low reproductive success of this species.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88726717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies showed the potential of phyllosphere bacteria in producing bioactive compounds, one of which is antimicrobial compounds. Andaliman (Zanthoxylum acanthopodium DC.) was a plant from the Rutaceae family that was commonly found in North Sumatra, and its fruit was widely used as a spice in traditional cooking by the Batak tribe. Several studies showed that the andaliman terpenoid has antioxidant and antimicrobial activity and an immunostimulating effect. This study aimed to explore the potential of andaliman phyllosphere bacteria. The research design method was a qualitative experimental model. The research stages used in compiling this paper consisted of phyllosphere bacteria isolation, phyllosphere bacteria morphological characterization, and Gram stain. This study succeeded in isolating 206 colonies of andaliman phyllosphere bacteria with various colony forms and cell morphology. From 64 samples of phyllosphere bacterial isolate observed, we found 25 different colony forms, and all samples were Gram-positive bacteria. Microscopic observations of gram staining showed that 44 isolates (68.75%) were cocci, 17 isolates (26.56%) were in the form of bacillus, and three isolates (4.68%) were in the form of coccobacillus.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88826121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technique requires rootstock and scion. The high rootstock demand for the replanting program drives the seeds’ suppliers to collect assorted seeds from cultivated fields, lead to a high variation in the germination rate. The time from seed dehiscent to seeding was hypothesized to be crucial inflicting an inconsistency in the germination rate and seedling rootstock growth. This present study used rubber seeds of the GT1 clone which were laid under trees’ shading to mimic the natural environment. Five laying periods were applied i.e., P0 (directly germinated, control), P1 (laid for one week), P2 (laid for two weeks), P3 (laid for three weeks), and P4 (laid for four weeks). Our study implied that the direct sowing after dehiscent was the best way to attain a high germination rate (GR) (51.67%) while delaying seed sowing for one week reduced the GR up to 22.04%. The longer delaying in P2, P3, and P4 did not show significant differences among them which were 13.33%, 1.19%, and 4.35% respectively. However, the seedling showed a similar growth rate including root/shoot ratio regardless of the laying period treatment. The necessity of establishing seed gardens for rootstock was highlighted in which the harvesting of the seeds could be controlled.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81924807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
