Abstract

ABSTRACT The corelation cell specialization with IAA (indole acetic acid) content  of Catharanthus roseus cell culture by the addition of tryptophan has been done. This research is part of a strategy to increased the catharanthine content. One strategy used is the addition of tryptophan as a precursor treatment. IAA was other compound of the effect of the addition of tryptophan. Research was conducted in the laboratory using MS medium with tryptophan 50-250 mg/L. The cell morphology observations made by Halogen Nikon microscope and documented with a digital camera Nikon DXM 1200F. The results showed that cell morphology is essentially the same for each treatment. The differences seen is the presence of more the long cells in the treatment of tryptophan. The longest ratio is the treatment of 150 mg/L tryptophan at day 14 of culture. Changes in cell morphology relationship more long (run specialization) has something to do with the IAA content after treatment tryptophan. The highest IAA content equal 214,79±0,90  µg/g dw  was occurred at day 14th after being treated tryptophan 150 mg/L with 75% long cells or cells specialization. The relationship between the content of IAA specialized cells showed a positive correlation of 0.80 or 80% of each other. Key words: Cell specialization, IAA content, catharanthine, tryptophan, Catharanthus roseus ABSTRAK   Hubungan antara spesialisasi sel dengan kandungan IAA (asam indol asetat) kultur sel Catharanthus roseus dengan perlakuan triptofan telah dilakukan.

Abstract

ABSTRACT This study aims to determine the effect of plant growth regulators and micro elements to cherelle wilt in cacao plants as well as finding the right business in tackling cherelle wilt in cacao plants. The research was carried out in the garden village folk Eris Eris Minahasa district for 8 months from January to August 2009. Spraying micro-nutrient elements is necessary to reduce cherelle wilt because the various treatments for the first observation is not significantly different, but the observations into two to seven observations to indicate a significant difference between treatments (percentage cherelle wilt on treatment without nutrient elements higher than sprayed). While spraying the treatment factor of plant growth regulators (NAA) is not necessary because the first observation and the two had no significant effect on the percentage of cherelle wilt affected only the third observation and further observations to a fourth, fifth, sixth and seventh again no effect. So is the treatment for fruit length and diameter showed that administration of the micro nutrients necessary for sprayed with micro nutrients result 22.10 cm higher than that is not sprayed is 19.43 cm. As for the diameter of the fruit is affected by plant growth regulators. Treatment is better than 200 ppm 100 ppm and 0 ppm (control). Keywords: NAA, cocoa, mikombi     ABSTRAK   Penelitian ini bertujuan mengetahui pengaruh pemberian zat pengatur tumbuh dan unsur mikro terhadap cherelle wilt pada tanaman kakao serta menemukan usaha yang tepat dalam menanggulangi cherelle wilt pada tanaman kakao. Penelitian ini dilaksanakan di kebun rakyat Desa Eris Kecamatan Eris Kabupaten Minahasa selama 8 bulan sejak Januari – Agustus 2009. Penyemprotan unsur hara mikro perlu dilakukan untuk mengurangi cherelle wilt sebab pada berbagai perlakuan untuk pengamatan pertama tidak berbeda nyata namun pada pengamatan ke dua sampai pengamatan ke tujuh menunjukkan adanya perbedaan nyata antar perlakuan (prosentase cherelle wilt pada perlakuan tanpa unsure hara lebih tinggi dari yang disemprot). Sementara faktor penyemprotan dengan perlakuan zat pengatur tumbuh (NAA) tidak perlu dilakukan sebab pengamatan pertama dan ke dua tidak berpengaruh nyata pada persentase cherelle wilt hanya berpengaruh pada pengamatan ke tiga dan selanjutnya pengamatan ke empat, ke lima, ke enam dan ke tujuh kembali tidak berpengaruh. Begitu juga perlakuan untuk panjang dan diameter buah menunjukkan bahwa pemberian unsur hara mikro perlu dilakukan sebab yang disemprot dengan unsur hara mikro hasilnya 22,10 cm lebih tinggi dari yang tidak disemprot yaitu 19,43 cm. Sementara untuk diameter buah dipengaruhi oleh zat pengatur tumbuh. Perlakuan 200 ppm lebih baik dari 100 ppm dan 0 ppm (kontrol).

ABSTRACT   This study aimed to examine the growth and production of potato crop varieties and varieties Granola Supejhon on two altitude, which is 750 m above sea level and 1200 m above sea level, studies using randomized block design with two factors. The first factor is the Granola variety and Supejhon. The second factor is the altitude, which is 750 m above sea level and 1200 m asl. The results of this study indicate that the rate Crop Growth Rate (LTT) and the Tuber Growth Rate (LTU) of Supejhon Granola varieties have a much higher altitude 1200 m asl (Modoinding) compared with altitude 750 m asl (Langowan). The altitude effect on the number of tubers / plant and production / plot, otherwise varieties had no effect on the number of tubers / plant, weight of tubers / plot and production / plot, and there is no interaction between variety and altitude. At altitude 750 m asl, both varieties yield an average production of tubers / plot of 1343.20 g (1.34 kg), whereas the altitude of 1200 m asl generate 7462.18 g (7.46 kg). Based on the average, the weight of tubers / plant and production / plots at very low reached by the two varieties of Granola and Supejhon well, so that the two varieties are not recommended to be cultivated at altitude 750 m above sea level. Further research is needed to examine other potato varieties that can be cultivated in areas with altitude of 750 m asl. Keywords: Potato, growth, production, level altitudes ABSTRAK Penelitian ini bertujuan untuk mengkaji pertumbuhan dan produksi tanaman kentang varietas Granola dan varietas Supejhon pada dua ketinggian tempat, yaitu 750 m dpl dan 1200 m dpl, penelitian  menggunakan Rancangan Acak Kelompok dengan dua faktor.  Faktor pertama adalah varietas  Granola dan Supejhon.  Faktor kedua adalah ketinggian tempat, yaitu 750 m dpl dan 1200 m dpl. Hasil penelitian ini menunjukkan bahwa Laju Tumbuh Tanaman (LTT) rata-rata dan Laju Tumbuh Umbi (LTU) rata-rata varietas Granola dan Supejhon memiliki nilai yang jauh lebih tinggi pada ketinggian tempat 1200 m dpl (Modoinding) dibandingkan dengan ketinggian tempat 750 m dpl (Langowan).  Ketinggian tempat berpengaruh terhadap jumlah umbi/tanaman dan produksi/petak, sebaliknya varietas tidak berpengaruh terhadap jumlah umbi/tanaman, bobot umbi/petak dan produksi/petak, serta tidak terdapat interaksi antara varietas dan ketinggian tempat. Pada ketinggian tempat 750 m dpl, kedua varietas menghasilkan rata-rata produksi umbi/petak sebesar 1343,20 g (1,34 kg), sedangkan pada ketinggian tempat 1200 m dpl menghasilkan 7462,18 g (7,46 kg).  Berdasarkan nilai rata-rata, bobot umbi/tanaman dan produksi/petak yang sangat rendah dicapai oleh kedua varietas baik Granola maupun Supejhon, sehingga kedua varietas tersebut tidak dianjurkan untuk dibudidayakan pada ketinggian 750 m dpl.  Perlu dilakukan penelitian lanjutan untuk menguji varietas kentang lainya yang dapat dibudidayakan pada daerah dengan ketinggian tempat 750 m dpl.

Abstract

ABSTRACT The objective of this research was to know the diversity of natural enemies (parasitoid and predator) on wet rice-field, so that could be bread to control pest insects with a tactic that is easy, cheap, efficiently and environment safe. Catching a natural enemies species was conducted in district of Tumpaan and Tenga (which was the centre of rice production in South Minahasa Regency) by sweeping (using insects trap) and direct observation in the field. The specimen insect was brought to the laboratory for identified. Diversity was measured using Shannon-wavers, and then continued to decide the species abundance average level. The natural enemies species which were found consist of five ordos of predator (Araneida, Hemiptera, Odonata, Coleoptera, and Orthoptera); 10 families; and 16 species; two ordos, 10 families and 13 species of parasitoid. The result of variance analysis showed that the abundance average level (J) of 29 species (predators and parasitoid) which were found almost the same and this value refer to value that almost the same on the diversity in species group (H) during observation either the old crop stadia or the location of rice plant.

Abstract

ABSTRACT This study aims to obtain entomopatogenik bacteria (Bacillus cereus) as a potential biological control of pests Spodoptera litura and determine the morphological characteristics and the potential power to kill isolate B. cereus. Explored endogenous bacteria from 99 soil samples from Minahasa regency, South Minahasa and Tomohon. Bacteria were isolated by selectively using methods Ohba and Aizawa  identified by colony and cell morphology. The results showed that of the 99 soil samples obtained 141 isolates were identified as Bacillus cereus. Screening 141 isolates of the 80 isolates contained S.litura larvae that can cause deadly diseases and test larvae  >50% after 96 hours with a dose of inoculum  1.5 x 107 spores / ml. Isolates that could potentially then be selected based on the pathogenicity then be developed into a biopesticide for pest control S. litura on cauliflower and broccoli plants. Keywords: Entomoopatogenic bacteria, Spodoptera litura, cabbage plants
