Abstract

Setting storage space temperature and time saving becomes an important application in supporting the development of plantations to provide seeds as needed and sustainable. The purpose of this research is to delay the rapid of seed germination in Magnolia champaca by assessing the effect of various suspend temperatures and times saving on seed germination of Magnolia camphaca . The research was conducted in Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Sriwijaya University in February until June 2016. The method was used completely randomized design pattern Factorial by 3 factors with 12 treatments and 3 replications with the temperature: temperature ± 31°C, temperature ± 25 °C, temperature ± 18 °C, temperature ± 4 °C and the retention of time 0 week, 2 weeks , 4 weeks and 6 weeks. The parameters include the observation of germination rate, germination, vigor index and sprout morphology. The results of the research the treatment of interaction of temperature and time saving significantly affected on germination rate, germination and seed vigor index of Magnolia champaca. Germination speed, germination and vigor index were both produced by the treatment of storage at a temperature of ± 18 °C and a temperature of ± 25 °C at all times to keep (2 weeks, 4 weeks, 6 weeks) compared to control treatment. A normal sprout produced in temperature treatment ± 18 °C and ± 25 °C temperature ranges between 90-93%. An abnormal sprout produced in control treatment (0 week) by 25%. Measurement of moisture content and physiological maturity level of Magnolia champaca seed needs to be done before it is stored and germinated to test the viability of seeds of sprouts.

Abstract

Campus of  Sriwijaya University in Indralaya , has a high diversity of flora including fern, especially the epiphytic ferns, whose existence is so widely found in oil palm plants.  Survey about  diversity of this epiphytic has been carried out  from July to November 2017, with aim to identifying the diversity of species of epiphytic ferns in oil palm plants on the campus of UNSRI Indralaya. The research method used is exploration method with direct collection technique from the field and then made herbarium. A total of 27 species of pteridophytes were collected from the study area. Floristic analysis of collected specimens was carried out to find out the families, genus and species. In this survey was  collected 27 species belonged to13 genera, 7 families such  Aspleniaceae, Blechnaceae, Davalliaceae, Lygodiaceae, Nephrolepidaceae, Polypodiaceae, and Vittariaceae. The most common types are Polypodiaceae is Drynaria quercifolia, Drynaria sparsisora, Microsorum pustulatum, Microsorum punctatum, Phymatosorus scolopendria, Polypodium verrucosum, Polypodium polysthicum,  Pyrrosia piloselloides, and Goniophlebium verrucossum. The most widely distributed species in oil palm is Davallia denticulata , Goniophlebium verrucosum, and Nephrolepis biserrata.

Abstract

This study is aimed to recognise the morphological characteristics of Nepenthes mirabilis and Nepenthes gracilis in peat swamp area including stem, leaf, tendril, pitcher, flower, fruit, and seed.  This study has been conducted in January  until April 2018, located in Petaling Village Tulung Selapan Sub-District, Ogan Komering Ilir, South Sumatera. This study uses an exploratory method and the the observation sample using the method of random plot is chosen by purposive sampling. Parameters observed morphological characteristics of Nepenthes include stems, leaves, tendrils, pitcher, flower, adn fruit, as well as measurement of environmental factors. Based on the study, the researcher obtained two types of Nepenthes which are Nepenthes mirabilis and Nepenthes gracilis in  peat swamp area of Petaling Village Tulung Selapan Sub-District, Ogan Komering Ilir. Nepenthes mirabilis has a teres stem, leaves that in the form of oblong to lanceolate, has a petiolate, the edge of the leaves is flat covered by smoothy hair, thick peristome in size of 0,4-0,5 cm. Meanwhile stem Nepenthes gracilis has triangular stem, leaves in formed of lanceolate, sessile, flat edge of leaves, thin peristome in size of 0,1-0,2 cm. The pitcher shape of Nepenthes mirabilis and Nepenthes gracilis are cylindrical, infundibulate, and waist. The flower of Nepenthes mirabilis and Nepenthes gracilis are compound in type of  raceme inflorescences. The fruit is formed as capsula, has four lobed, and contains numerous seeds. The seed is spindle-like and white colored.

Abstract

The potential for the carbon content of mangrove forests is four times greater than other forest, this important information needs to be measured to determine the value of carbon stocks at a given time and their changes. The research was done in November 2018-March 2019 in Berbak and Sembilang National Park, Banyuasin, South Sumatra, in each location three transect lines were determined perpendicular to the land as far as 100 m and made 5 plots of 10 x10 m with a distance between plots of 10 m on each transect. The aims are to determine species richness, biomass value, estimated stored carbon reserves, and CO2 uptake in Bruguiera spp. stands. Analysis of comparison of the results of data using descriptive statistical analysis. Based on the results of the study found 4 types of Bruguiera spp. that is Bruguiera cylindrica, Bruguiera parviflora, Bruguiera gymnorrhiza, and Bruguiera sexangula. The total value of the biomass of 410,01 ton/ha, carbon stocks estimation of 189,02 ton C/ha, and the CO2 uptake of 693,69 ton CO2/ha. The results of a statistic descriptive analysis of estimated carbon stocks and CO2 uptake, in Barong Kecil river where of the most areas has been deforested into ponds, have the lowest value than the other research locations like Solok Buntu and Bungin river, with sequential carbon values of 11,51 ton C/ha in Barong Kecil river, 227,66 ton C/ha in Bungin river, and 327,88 ton C/ha in Solok Buntu river, and CO2 uptake of 42,23 ton CO2/ha in Barong Kecil river, 835,52 ton CO2/ha in Bungin river, and 1.203,33 ton CO2/ha in Solok Buntu river.
