Abstract

Rice (Oryza sativa L.) is a plant that is not resistant to the salt stress, but the development of agriculture in coastal areas requires the analysis of rice genotypes that are resistant to the salt stress. The salt stress may cause chromosomal abnormality, such as sticky chromosome. This study was aimed to analyze the influence of the salt stress on the formation of chromosomes in four rice genotypes originating from Bantan Air village, Bengkalis. This research was conducted using randomized block design (RBD) with two factors, i.e. NaCl concentrations (0 mM, 60 mM, 75 mM, and 90 mM) and the rice genotypes (IR64, Indragiri, Solok, Sadani, Yamin, and Amat Candu) with three replications for each treatment. Normal anaphase chromosomes were visible in control, whereas sticky chromosomes were seen in 90 mM salt exposure. It concluded that salt stress may cause sticky chromosomes.

Abstract

Water apple is one of agricultural commodities in Indonesia, including Riau Province. In this Province, this species is mainly distributed in Pekanbaru and Kampar. The diversity of water apple in both regions is high, however, there is no record of its morphological diversity study. This study aimed to identify and to know the diversity of water apple from Pekanbaru and Kampar based on the morphological characters. This research had been carried out from April 2013 to January 2014 using survey and observation methods. The morphological characters were observed and described. The scoring of morphological characters was then analyzed using NTSYS-pc 2.02i. The numbers of variation found in tree, leaf, flower, fruit and seed were 4, 5, 7, 9 and 3 respectively. The similarity coefficient ranged from 0.16 to 0.77. The highest similarity was found on individual R8 and R7, while the lowest similarity coefficient was found on individual KM10 and BR8. Result of cluster analysis showed that the relationship of water apples ranged from 0.41 to 0.78.

Abstract

This study aimed to determine the regeneration of  Rhizophora on mangrove forest, Sungai Rawa  village, Sungai Apit  Sub-District, Riau Province.  This study had been carried out in February 2014.  The sampling were collected with  purposive sampling using nested plot. The size of plot for tree, pole, and sapling were 20x20 m, 5x5 m and 2x2 m, respectively. Three locations were selected for study sites, i.e. low, mid, and high activity locations. The result showed that only one  Rhizophora  spesies i.e  Rhizophora apiculata,that found in all of the locations with  300% Important Value Index for each growth stage.  R. apiculata  had good regeneration status. The highest density in each stage was found in the low activity location, with the  density value for  seedling, sapling and tree were 17000 individuals / ha, 1200  individual/ha and 318 individual / ha, respectively. While the lowest density was found in different study sites, i.e. high activity location for seedling (3600 individual/ha) and in the mid activity location for sapling (660 individual/ha) and trees (108 individual/ha).

Abstract

The vegetation analysis of  Avicennia  sp.  in Sungai Rawa coastal had been conducted from January to February 2014.  This research aimed to determine the species composition, structure, and condition of mangrove  vegetation, as  well as  sediment characteristic.  Sampling were conducted at three different station based on purposive sampling method using multilevel plot (Nested Quadrat).  The  results showed that mangroves  species  found in  the  coastal village of Sungai Rawa  were  Avicennia alba  and  Avicennia lanata. The level of seedling, saplings and trees showed that  A.alba  was dominant at three station. Analysis of sediment showed that the substrate within  three  station were sand and mud. The analysis showed that mud substrate was dominant in all of the reseach site. The corelation betwen the vegetation and substrate showed a positive corelation with mud substrate and negative corelation with sand substrate.

Abstract

Bulbophyllum and Vanda are tropical orchids that are widely distributed in many regions inIndonesia, as well as in Pekanbaru, Riau. These genera have their own beauty with uniquemorphological characters, therefore they attract most people especially orchid lover. Thisresearch aimed to identify the species of Bulbophyllum and Vanda in Pekanbaru and todetermine their relationship based on their morphological characters. One hundred eighteencharacters were scored from 10 orchid species, these characters were then analyzed usingNTSyst 2.02. The result identified five Bulbophyllum species (B. vaginatum, B. medusa,B.machrantum, B. echinolambium and B. coroliferum) and five Vanda species (V. teres, V.dearei, V. limbata, V. tricolorand V. sumatrana). The similarity coefficient was rangedfrom 0.24-0.72. The dendogram was mainly divided into two groups (A and B). Group Aconsisted of all Vanda species while B consisted of all Bulbophyllum species.

Abstract

Biosphere Giam Siak Kecil-Bukit Batu reserve was based on managed zonations as a multi-benefit management approach. This region has a fairly large carbon stocks stored in its natural peat swamp forest ecosystems. How ever the general condition of the peat swamp forest in the landscape Biosphere Giam Siak Kecil-Bukit Batu currently has suffered damage, especially in the buffer and transition zones. The threat to the existenceof protected areas are not only coming from forest fires factors alone, but also from encroachment and illegal logging. Therefore, is requires a recovery effort. This research aims to determine the survival rate and to estimate above ground biomass accumulation of the main tree species of peat swamp forest which was used to restore the burnt-peat. Estimate total biomass accumulation on the surface using allometric equations. Result of this research prove that the type of Jelutung (Dyera polyphylla) has the best survival rate among the values of other types (98%), while the species Pisang-pisang (Mezzettia parviflora) have a survival rate of 35%. Total above ground biomass accumulation on thehighest level found in Jelutung (Dyera polyphylla) it was 499.015 kg/ha/year, while the lowest total above ground biomass accumulation found in Meranti batu (Shorea uliginosa) 88.867 kg/ha/year.

Abstract

Musa balbisiana Colla in Kuantan Singingi Regency can survive from the disease which causes banana in many other areas disappeared. Currently, there is no information about the diversity of M. Balbisiana from Kuantan Singingi. The purposesof this study were to record, to characterize, and to measure the diversity of M. balbisiana from Kuantan Singingi based on morphological characters. M. balbisiana Colla plants was sampled from three locations in Kuantan Singingi, they were Pangean, Cerenti, and Inuman. Morphological characters of M. balbisiana were analyzed using 88 characters. Analysis of UPGMA was conducted to find out the diversity of M.Balbisiana. We found six M.balbisiana cultivars, namely Aceh, Bungo, Kara, Jambi, Nipah, Beluluk. Similarity coefficient values between six banana cultivars ranged from 63%-89%. Cluster analysis based on 88 morphological characters of M. balbisianaproduced dendogram with 2 primary groups at percentage of similarity values of 66%.

Abstract

The stem of rambutan tree (Nephelium lappaceum) has suitable microenvironment for the growth of epiphytic flora, due to its rugose stem. Therefore, it may trap and collect plant debrish or other organic material as well as rain drops. One of plant group found on the rambutan tree is orchid (Orchidaceae). This study aimed to observed the morphology of epihytic orchids on rambutan tree. The result showed two orchid species, Acriopsisliliifolia (J. Koenig) Seidenf. and Dendrobium crumenatum Sw.

Abstract

Cempedak (Artocarpus champaden Lour.) is one of the special fruits in Southeast Asia which is the prima donna of the community. In the province of Riau, cempedak found in many areas of Kampar regency. This study aims to identify the types of cempedak that exist in Kampar regency. Based on the results of the research, cempedak is categorized into four cultivars ie cempedak pulp cultivars, cempedak forest cultivars, cempedak langkat cultivars and cempedak nangkadak cultivars, from four cempedak cultivars found, Nempadak cempedak cultivars and Langkat cultivars are the most superior cempedak cultivars because they have fruits big, lots of content, thick meat and sweet taste.
