Abstract

Pitcher plants (Nepenthes spp.) are an important economically as ornamental and medicine plants. They have a high degree of morphological variation and after ambiguis to distinguish among picher plants. The objective of research was to observe the genetic relationship among pitcher plant based on RAPD markers. Nine pitcher plants were analyzed using five RAPD primers. The result of this study showed that five RAPD primers selected were generated total 60 DNA fragments ranging from 150-1.450 bp. Genetic distance among pitcher plants ranged from 0.105 [N. trichocarpa (NXT) vs N. mirabilis (MIR)] to 0.545 [N. ampularia hijau (AHI) vs N. ampularia peristom merah (APM). Based on the dendogram of UPGMA, pitcher plants divided into four clusters. First cluster was formed six pitcher plants, e.g. Nepenthes ampularia corong (ACO), Nepenthes mirabilis (MIR), Nepenthes x trichocarpa (NXT), Nepenthes ampularia batik (ABA), Nepenthes grasilis merah (GME), Nepenthes grasilis hijau (GHI). Second, third, and fourth clusters having only one species, namely Nepenthes ampularia hijau (AHI), Nepenthes ampularia panjang batik (APB), Nepenthes ampularia peristum merah (APM), respectively. The result of this investigation will help breeders for pitcher plants improvement program in future.

Abstract

Soybean is a cheap source of vegetable protein. Effort to increase of soybean production have constrained the narrowness of fertile land. One way to increase soybean production in less fertile land is inoculation of mycorrhizal. The objective of this study are to conduct effect of mycorrhizal inoculation on physiological of soybean cultivars. The 18 x 2 factorial experiment was set up in completely randomize design using three replications during June to October 2013. The eighteen soybean cultivars (Grobogan, Burangrang, Sibayak, Kaba, Tanggamus, Anjasmoro, Argomulyo, Wilis, Panderman, Ijen, Baluran, Galunggung, Petek, Garut, Gepak Kuning, Malabar, Seulawah, Sinabung) were assigned as the first factor. The second factor was mycorrhizal inoculation with without mycorrhizal inoculation and mycorrhizal inoculation. Data were recorded for dry weight of shoot, dry weight of root, dry weight of plant, root shoot ratio at 56 days after planting, and harvest index at 84 days after planting. The result showed that mycorrhizal inoculation significantly increased the dry weight of shoot, dry weight of root, dry weight of plant and harvest index but significantly decreased of root shoot ratio.

Abstract

Weed is one of the problems in palm oil plantation. The research aims to determine the compositions and the dominance of the weeds in immature and mature stages then compare the weeds compositions between both. The research was conducted in Pelalawan Districk, Riau Province, from March to May 2017. The research was conducted by descriptive method. Sample was taken using a square plot measuring 1x1 meter with 10 replications. The plot sample was taken in a circle in immature plantings and in path mature plantings. The result shows that the diversity of the weeds was higher in immature plantings (18 species) than in mature stage (10 species). Weeds composition in palm oil plantation is much greater during the immature phase rather than mature phase because the high spaces and the high of sunlight in immature phase offer opportunity for the weeds to grow ubiquitously. None of the species in immature plantings are dominant species but in mature plantings there is one dominant species namely Nephrolepis bisserata. Perennial weeds species is a dominant weed type of both phase. The weeds compositions of immature and mature plantings shows the different compositions based on similarity index (IS Sorensen) that caused by the different environment condition. The weeds that found in mature plantings are a type of shade tolerant weeds. Nephrolepis bisserata, dominant species in mature plantings, is a shade tolerant species which can also increase air humidity and decrease the air temperature.

Abstract

Palm oil can experience high salinity waterlogging at the same place and time; however, the effects of these two conditions on growth and morphology of palm oil root was not fully understood. Research has been done by combining two levels of salinity (high salinity and low salinity) and three levels of waterlogging (without waterlogging, twoweek waterlogging intervals, and four-week waterlogging intervals). The study was conducted in pots for 4 months used 4 months old oil palm planting material. The results show that high salinity and waterlogging consistently decrease the oil palm root growth parameter. Longer duration of waterlogging decreases root growth greater than shorter waterlogging. High salinity and waterlogging do not consistently change the ratio of the area of each primary, secondary, and tertiary root tissue. Palm oil forms pneumatophore and aerenchyma under both non saline and saline waterlogging. High salinity followed by waterlogging can compensate the negative effects of salt ions (Na+ and Cl– ) through morphological adaptations, changes in ion absorption rate, and root membrane impermeability.

Abstract

Gerbera, an ornamental flower plant of herbs, has been commonly cultivated as a potted plant or cut flowers. The main problem in conventional propagation Gerbera is insufficient amount of seeds to meet the growing demand of planting material. This study aims to develop effective and low cost in vitro system of Gerbera propagation; therefore Gerbera seeds are available in large quantities and cheaper price. The research was conducted in laboratory of plant tissue culture, Stiper Agriculture Institute, Yogyakarta from March to June 2017. The young leaves Gerbera jamesonii, commonly planted in the Dieng plateau area, were used as explant. The explants were inoculated in solid medium which contain of ¼ MS (Murashige and Skoog), sucrose 30 g/L and combination of NAA (Naphthalene Acetate Acid) and BAP (Benzilaminopurin). The combinations of NAA and BAP were A0B0 (NAA 0 mg/L + BAP 0 mg/L); A1B0 (NAA 1 mg/L + BAP 0 mg/L); A2B0 (NAA 2 mg/L + BAP 0 mg/L); A0B1 (NAA 0 mg/L + BAP 1 mg/L); A2B1 (NAA 2 mg/L + BAP 1 mg/L); A0B2 (NAA 0 mg/L + BAP 2 mg/L); A1B2 (NAA 1 mg/L + BAP 2 mg/L), A2B2 (NAA 2 mg/L + BAP 2 mg/L). It was observed that ¼ MS medium supplemented with NAA and BAP can be used for callus induction from leaf explants of Gerbera jamesonii. Callus began to be induced three to four weeks after planting. Medium with combination of NAA 2 ppm and BAP 1 ppm (A2B1) produced the best characterized callus, with shiny green appearance and clustered form (embryogenic).

Abstract

Kebutuhan air untuk irigasi dapat dipenuhi oleh sumber air sumur maupun air sungai. Oleh karena itu, keberlanjutan sumber air tersebut haruslah dipelihara. Salah satu upaya pengelolaan air adalah pengelolaan sumber imbuhan atau recharge air tanah. Sumber imbuhan air tanah dapat berupa air hujan, infiltrasi danau/air sungai di hulu maupun aliran lateral air tanah. Studi ini akan memaparkan penggunaan data isotop air dalam menentukan sumber imbuhan air tanah secara kualitatif. Selain itu, akan dipaparkan hasil analisis data isotope dengan menggunakan GIS. Data isotop air tanah diperoleh dari air sumur disebuah area pertanian buah buahan seluas 14 Ha. Hasil analisis menunjukkan bahwa di daerah pertanian tersebut air tanah berasal dari air hujan setempat dan sumber air tanah dari aliran air tanah yang berada dihulu lokasi pertanian. Namun pada studi ini, belum dapat diketahui sumber mana yang lebih dominan. Sehingga dibutuhkan studi kuantitatif untuk menentukan rasio sumber imbuhan air tanah. Kata Kunci: Air tanah, Sumber Imbuhan, Isotop air, GIS
