Abstract

The objective of this study was to identify the adaptability of twelve artemisia mutant genotypes, which were planted in three locations with different altitude, as a result of gamma irradiation. Randomized Complete Block Design (RCBD) was applied in this research with three replications as blocks. The genotypes 1B, 1C, 1D, 2, 3, 4, 5A, 6B, 7A, 8, 14, 15 and two control genotypes as parent genotype from seed and from in vitro were used. The genotypes were planted in three different locations such as Mount Putri, Cianjur (1450 m above sea level), Pacet, Cianjur (950 m above sea level) and Cicurug, Sukabumi (540 m above sea level). Based on the method of postdictive and predictive success, the model used was AMMI2 which was able to explain up to 100% of interaction-influenced variation. The genotypes which were found stabile and adaptive in these three locations were 1B, 1C, 1D, 6B and 15. Genotypes 3 and 7A were adaptive specifically in Pacet area, 5A was adaptive for Gunung Putri while genotype 4 was for Cicurug only.Keywords: AMMI, Artemisia annua, mutant genotype, adaptability

Abstract

Keladi tikus merupakan tanaman obat yang bermanfaat sebagai obat kanker. Keladi tikus memiliki kandungan kimia diantaranya adalah alkaloid, flavonoid, saponin, steroid dan glikosida. Keladi tikus memiliki keragaman genetik yang rendah. Untuk meningkatkan keragaman telah dilakukan mutasi secara fisik melalui iradiasi sinar gamma pada kultur in vitro keladi tikus. Media MS dengan penambahan 0.5 mg/l 2.4D dan 0.1 mg/l kinetin menghasilkan jumlah tunas terbanyak yaitu 14.38 plantlet. Kalus embriogenik mutan dihasilkan melalui induksi dengan sinar gamma 6 gray. Kalus embriogenik diregenerasikan menjadi 59 tunas mutan. Plantlet mutan yang dihasilkan telah dideteksi dengan marka molekuler RAPD dan menunjukan perubahan genetik. Beberapa galur mutan yang telah diperoleh memiliki keragaman tinggi secara morfologi dan genetik. Keragaman genetik klon mutan generasi pertama (MV1) sampai generasi keempat (MV4) yang diperoleh telah dideteksi secara genetik molekuler dengan RAPD. Beberapa klon MV5 (mutan stabil) memiliki kandungan senyawa bioaktif antikanker tinggi berdasarkan GC-MS. Analisis GC-MS menunjukkan bahwa tanaman mutan mengalami peningkatan kandungan senyawa antikanker dibanding kontrol serta senyawa baru yang tidak ditemukan di kontrol. Beberapa klon unggul yang dihasilkan perlu dikembangkan sebagai bahan baku obat antikanker. Keladi tikus unggul bermanfaat untuk mencegah dan mengobati penyakit kanker pada masyarakat Indonesia.

Abstract

The conventional propagation of physic nut (Jatropha curcas) is difficult, because it requires a high number of mother plant, which is very limited. In vitro culture is an alternative technique to conventional one to solve the problem.  An experiment was done to obtain the best in vitro culture media for shoot induction and multiplication. This research was separated into two steps, (1) in vitro induction of explant growth, and (2) in vitro shoot multiplication.  Results showed that medium of WPM + 2.0 ppm BAP induced shoot and leaf better than the control.  The highest number of leaf axillary's multiplication was obtained from the medium WPM + 2.0 ppm BAP + 0.1 ppm NAA. Various medium formulations for the induction and multiplication of shoots resulted in highly leaf fall.  The use of DKW + 2.0 ppm BAP + 0.4 ppm TDZ + 3.0 ppm AgNO3 medium has effectively induced shoot multiplication and reduction of dehydrated leaf. Meanwhile, the used of DKW medium supplemented with 5 ppm kinetin resulted in the best shoot elongation.   Key words :  Induction, in vitro, Jatropha curcas, shoot, multiplication
