Abstract

Plant breeding is an effort to develop plants by manipulating the genetic system of plants to get new superior cultivars. Plant breeding often produces incompatible seeds, so a rescue process is needed to reduce the risk of embryo death. The addition of gibberellic acid could break the seed dormancy for seed that hard to germinate. The purpose of this study was to find out the best concentration of gibberellic acid for germination of citrus globular embryos from protoplast fusion. Research was conducted at the Biology and Cell Biology Research Group In Vitro Culture Laboratory, Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (BB BIOGEN), Agricultural Research and Development Agency, Ministry of Agriculture, Bogor. The study used Completely Randomized Design (CRD) with concentration 0, 1, 2 and 3 ppm of gibberellic acid as treatment, each consists of 7 replicates. This study used globular embryos measuring ± 3 mm of inbred FS 29 and FS 89 from protoplast fusion between Siam Simadu and Mandarin Satsuma citrus. Observations were made on the percentage of germinated embryos, time of germination, the number of the complete and incomplete shoot (abnormal, only part of the roots or buds that developed). Data were analyzed using Crosstab analysis test with IBM SPSS Statistics 22 software. Result showed that addition of gibberellic acid induce faster germination time and increase seedling percentage. The best germination medium for citrus FS 29 was VMW with 2 ppm and 3 ppm gibberellic acid with the seedling percentage around 85,7% in 7 days, while the best germination medium for citrus FS 89 was VMW with 1 ppm gibberellic acid with 100% seedling embryos in 8,5 days. VMW medium added with 1 ppm, 2 ppm and 3 ppm gibberellic acid for citrus FS29 and VMW medium added with 2 ppm and 3 ppm for citrus FS89 were good to get the complete sprouts with a succes rate of 100%.

Abstract

Jeruk siam Kintamani disukai oleh konsumen karena memiliki rasa manis, harum, dan daging buahnya lunak. Namun jeruk ini memiliki biji relatif banyak dan warna kulit kurang menarik sehingga kalah bersaing dengan jeruk yang diproduksi oleh negara lain. Alternatif untuk meningkatkan kualitas buah jeruk adalah melalui induksi mutasi in vitro menggunakan sinar gamma. Tunas putative mutan jeruk siam diperbanyak secara in vitro sehingga diperoleh duplikat dari masing-masing mutan. Penggunaan jenis media dan zat pengatur tumbuh pada konsentrasi yang tepat merupakan salah satu kunci keberhasilan dalam kultur jaringan. Tujuan penelitian ini adalah untuk memacu multiplikasi tunas dari eksplan buku. Bahan yang digunakan yaitu plantlet jeruk siam Kintamani hasil iradiasi sinar gamma dengan dosis 0, 4,5, 5, dan 5,5 Gy. Penelitian multiplikasi tunas secara in vitro menggunakan eksplan buku dengan perlakuan 7 jenis media. Hasil penelitian menunjukkan bahwa pada perlakuan media MS VMW + BAP2 + GA2 mampu memperbanyak jumlah tunas, sedangkan media MS VMW mampu meningkatkan jumlah daun dan perbanyakan jumlah akar. Kata kunci : putative mutan, karakterisasi, multiplikasi, mutasi
