Abstract

Keberhasilan kultur jaringan dipengaruhi oleh jenis atau tipe eksplan dan penambahan zat pengatur tumbuh. Kinetin (6-furfurylaminopurine) merupakan zat pengatur tumbuh golongan sitokinin yang banyak digunakan dalam kultur jaringan. Penelitian ini bertujuan mengetahui pengaruh penambahan kinetin dan tipe eksplan terhadap pembiakan in vitro jabon merah. Hasil penelitian menunjukkan bahwa kinetin 7 ppm memberikan pengaruh terbaik terhadap pertumbuhan daun dan akar. Tipe eksplan bagian pucuk merupakan bagian terbaik digunakan untuk pembiakan in vitro. Keyword : Antocephalus macrophyllus (Roxb.) Havil, kinetin, in vitro, tipe eksplan

Abstract

Pertumbuhan tanaman dapat dipengaruhi oleh adanya keragaman mikroba yang yang terdapat di rhizosfer, salah satunya yaitu cendawan. Cendawan rhizosfer yang terdapat pada akar tanaman dapat meningkatkan pertumbuhan tanaman dan perlindungan terhadap mikroba tertentu. Penelitian ini bertujuan untuk mengidentifikasi cendawan rhizosfer. Metode penelitian yang digunakan yaitu isolasi cendawan menggunakan teknik pengenceran 10-2 dan 10-3 , serta identifikasi cendawan berdasarkan karakter morfologi. Hasil isolasi cendawan rhizosfer diperoleh sebanyak 33 isolat yang terdiri atas 5 genus yaitu Aspergillus, Trichoderma, Rhizopus, Penicillium dan Fusarium.Kata Kunci : Suren, Rhizosfer, Cendawan

Abstract

Rehabilitate forest and farm critical must special attention and need of the new method that more practical, quick, and cheap. Method of seed ball is its alternative method. with consideration referred, then this research bent on for (1) know seed amount every seed ball that give percentage grows and plants growth sengon the best (2) know size of seed ball diameter the best to percentage grow and plants growth sengon; (3) know appropriate type of farm closing to percentage grow and plants growth sengon; (4) know interaction influence between seed amount every ball, level of seed ball, type of the best farm closing to percentage grow and plants growth sengon at the site. This research is executed start month September 2012 up to final December 2012 in district Tinggimoncong Gowa Regency. this research uses random design complete pattern factorial that consisted of 3 factor that is seed amounts every seed ball as first factor with 4 levels that is 5 seeds, 7 seeds, 9 seeds, and 11 seeds every seed ball, second that is large size factor its diameter of seed ball that consisted of 4 levels that is 2.5 cm, 4 cm, 5.5 cm, and 7 cm, third factor that is farm closing that consisted of 4 levels that is opened (grass), coppice, beams, and cleaned (disc with diameter 20 cm). The three of this treatment factor are combined until got counted 4 x 4 x 4 = 64 treatment units. Every treatment unit consisted of 3 seed balls and repeated 3 times until required 64 x 3 x 3 = 576 seed balls. Variable that perceived is time starts germinate and percentage germinates every week during a month first, plants growth (high and leaf amount) every month after second month for 2 month. Research result indicates that treatment of land cover has an effect on reality to germination percentage, leaf amount, and high plants as for seedball diameter, seed amount and interaction between land cover and seedball diameter have an effect on reality to percentage of germination and leaf amount. Treatment of grass land cover gives influence is done well by germination percentage, leaf amount, and high plants. Seedball diameter 7,0 cm and seed amount 11 seeds give influence is done well by germination percentage. Combination of grass land cover treatment and diameter of seed ball 7,0 cm give best influence. Key words: Formulation, biological control agent, Aspergillus sp., and tablet.

Abstract

This study aims  to investigate genetic diversity of identified pine stands at Unhas Extention Forest based on morphological markers.  The methods used are observation and measurement of the variables leaves, stems and plant height.  An analysis of data used the NTSYSpc program (Numerical Taxonomy and Multivariate System) version 2.0.The results showed that there are some morphological similarities such as  the shape of the leaves (needles), the shape of the curve of the leaf tip (tapered), the shape of the curve of the leaf base(tapering), the shape of the leaf margins (flat), the color of top surface of the leaf (dark green), the color of lower surface of leaf (dark green), the state of the upper surface of the leaf (smooth), the state of the lower leaf surface (rough), bark texture (grooved), rod shape (square), and the shape of the canopy (cones) while the other variables showed a difference. The genetic diversity of individual spine based on morphological observations is low.   Keywords  :  Morfological, Genetics,  Diversity, Pine
