Abstract

IRR 42 clones belonging to clone a slow starter who has good growth and great girth, but production of the rubber tends to be low when compared to other superior clones. This study aims to obtain stimulant treatment may be able to optimize the production potential clones IRR 42. The research wasconducted at the Research Institute for Experimental Sungei White, Rubber Research Center for four months (May-August 2012) in the area of crop planting clones IRR 42 years in 2006 (6 years old plants). The treatments tested include concentration of stimulant (S) consisting of 1.25%, 2.50%, 3.50% and 4.50%,treatment application interval (W) consists of one and two times per month as well as application control treatment (without stimulants). The results showed an average production of 2.50% on stimulant treatment and 4.50% at intervals of twice per month (S2W2 and S4W2) have higher production compared with other treatments. In general, plant physiology is still below the threshold. S2W2 treatment is the best treatment to optimize the potential of the plant because it has high production but showed lower stress than the exploitation S4W2. Further research is needed in a longer period of time to determine plant responses to each treatment

Abstract

Growth and biomass Rhizopora apiculata BI seedlings under varied salinities and their lipid content at tree stage. The research was conducted at Green house, Faculty of Agriculture and Research Laboratory, Faculty of Pharmacy, University of North Sumatra from August 2011 to July 2012. This study aims to determine the effect of salinity on the growth and biomassa of mangrove non secreter R. apiculata seedlings level and lipid and NSL (Nonsaponifiable Lipids) content at tree level. Five levels of salinities of 0%, 0.5%, 1.5%, 2%, 3% were treated and seedlings were planted for 5 months. The results showed that maximum growth of R. apiculata seedling at 1.5% concentration, leaf number and leaf area were in the salinity of 0.5%. Stem and root biomass achieved in 1.5%, while the leaf biomass in the salinity of 0.5%. The content of total lipid and NSL obtained from the leaves and the roots R. apiculata tree. The content of total lipid R. apiculata trees in the leaves (9.60 mg)  were more amounts than in the roots (6.40 mg). NSL content of R. apiculata trees in the roots (0,226 mg) were more than in the leaves (0.10 mg). The results of this study may provide information to the rehabilitation program in order to obtain R. apiculata seedlings growing best based on their salinities.   Keywords : Mangrove, Rhizopora apiculata, Salinity, Morphology, Content of Lipid and NSL (Non Sapofiniable Lipid)

Abstract

This study described the analyzing of composition and diversity of triterpenoid and phytosterol in North Sumatera mangrove species A. corniculatum as biomarkers and input lipids in to estuarine ecosytem. Phytosterols found  in the  roots and leaves of A. corniculatum were stigmasterol, campesterol, β-sitosterol, and cycloartenol. Taraxerol, β-amyrin, germanicol, betulin, α-amyrin, lopenone and lupeol were the triterpenoids identified. Betulin was the major component triterpenoids had the highest content (31,8%) in the  roots. This research may provide information  the composition of triterpenoid and phytosterol to contribute to estimating the lipid input and as biomarker  from                     A. corniculatum to estuarine ecosytem. Keywords : Mangrove, A.corniculatum (L) Blanco, Biomarker, Estuarine, and Lipid.

Abstract

  This study aims to determine the characterization of isoprenoid compounds in the mangrove A. alba and seedling growth of A. alba at different levels of salinity. The results showed the total lipids in the leaves of A. alba (21 mg) was higher than that in the roots (11,7 mg). Total Non Saponifiable Lipids (NSL) content in the leaves of A. alba (1,1 mg) greater than that in the roots (0,6 mg). NSL composition of A. alba consists of 3 major factions namely triterpenoids, phytosterols, and other compounds. Phytosterol composition in the leaves and roots of A. alba showed the presence of compounds such as campesterol, stigmasterol and β-sitosterol. As frase for the composition triterpenoid found the presence of β-amyrin, germanicol, betulin, lupeol and α-amyrin. Phytol, cholesterol, and squalene were also found as the other compounds. The content of the NSL triterpenoid was higher than phytosterol in the leaves and roots of A. alba. The results also showed that phytol compounds had the highest content of leaves of A. alba (71.4 %) and the β-sitosterol had the highest content of root A. alba (27.8 %). Based on the analysis of the effect of salinity on seedling growth of A. alba showed that the salinity of 2% significantly affected the seedling height and diameter of 3 months of A. alba. Keywords :Avicennia alba, Non Saponifiable Lipids (NSL), Triterpenoid, Phytosterol, and Salinity.

Abstract

The purpose of this study is to analyze growth of A. ilicifolius seedling in response to salinities and its isoprenoid composition. The mangrove seedling were grown under different salinities for 5 mounth. The maximum growth of A. ilicifolius seedlings was in 0.5 % salinity and this elevation appeared to be attenuated by increasing of salinity. The results showed the composition of the isoprenoid in  A.ilicifolius  were consist of four phytosterols namely stigmasterol, campesterol, β-sitosterol, cycloartenol, and six triterpenoids : taraxerol, β-amyrin, germanicol, betulin, α-amyrin and lupeol. This research may provide information the characterization of triterpenoid and phytosterol of A. ilicfolius seedlings. Keywords : Mangrove, A.ilicifolius Linn, isoprenoid, and Salinity
