Abstrak Keragaman bunga kertas saat ini berasal dari persilangan atau mutasi yang dilakukan oleh manusia. Penelitian ini bertujuan untuk menginduksi keragaman bunga kertas dengan metode kultur jaringan. Penelitian dilakukan di Laboratorium Kultur Jaringan dan Kebun Percobaan FMIPA, UNY. Metode yang digunakan dalam penelitian ini adalah induksi menggunakan sitokinin BAP (benzyl amino purin) dalam media MS. Eksplan diperoleh dari tanaman bunga kertas yang sudah dikecambahkan di tray perkecambahan dan penanaman in vitro. Sterilisasi untuk penanaman dengan teknik kultur jaringan menggunakan detergen, alkohol 70%, Clorox 10% dan 5%, serta aquadest steril. Media yang digunakan adalah media MS (Murashige dan Skoog) ditambah dengan BAP (konsentrasi 2,4,6, dan 15ppm). Hasil penelitian menunjukkan penambahan BAP dalam media MS mampu memicu pertumbuhan kalus pada eksplan nodia dan daun Zinnia sp. Konsentrasi 4 dan 6 ppm BAP mampu menginduksi tunas dari kalus pada eksplan nodia dan keragaman hanya dapat dilihat pada tipe kalus. Terdapat perbedaan tipe kalus jika konsentrasi BAP sangat tinggi (15 ppm). Pengamatan pada sel-sel ujung akar hanya menunjukkan sel-sel berukuran kecil dengan inti sel tanpa terlihat kromosom di dalamnya. Perlu penelitian lebih lanjut untuk induksi tunas atau embrio somatik dari kalus hasil induksi BAP pada media. Pengamatan kromosom dapat diperbaiki dengan penambahan zat kimia lain atau perubahan waktu pengambilan sampel dan perendaman. Kata Kunci : keragaman, Zinnia, BAP, kromosom

A method used for the development of dry areas/marginal lands is the improvement of soil structure and addition to the media to support the growth and development of crops. Tomatoes have the potential to be developed in marginal lands due to its high nutrition, high in demand and easy to be cultivated. One of the method used to improve planting media is the addition of microorganism such as mycorrhiza which can help the absorbtion of water and nutrition for plants. The interval of irrigation is used as a simulation of drought. This research aim was to observe the effect of mycorrhiza in the soil on the growth and development of tomato with several treatments of irrigation. The method used was the addition of 4 g of mycorrhiza per polybag (size 30x30 cm2), using Complete Randomized Design. There were 6 combinations of treatments. The treatments were : 3 interval of irrigation (every day, every 7 days and every 14 days), and 2 treatments of mycorrhiza (0 g and 4 g). There were 3 repetition for each combination of treatments. The results showed that the addition of mycorrhiza can increase significantly plant fresh and dry weight and also root length. The difference in plant height, number of branches, number of leaves, plant growth rate and percentage of infection were caused by the difference in irrigation interval. The difference in the varieties used also contribute to a difference in the percentage of infection. Further research must be made on the effect of mycorrhiza with addition of inorganic fertilizer to increase the growth and development of tomato plants in water stressed condition. Keywords: mycorriza, tomato, draught simulation

A plant that has a good prospect in the development and cultivation as medicinal plant is binahong (Anredera cordifolia L.). Secondary metabolites have been used as coloring substance, food coloring, and medicine. Callus induction using tissue culture has been used to produce secondary metabolite with a higher concentration than obtained directly from the plant. The aim of this research was to induce callus from the leaf of Binahong using various concentrations of Plant Growth Hormones in MS media. The method used in the propagation of callus used the leaf explant of binahong with Completely Randomized Design (CRD). The leaf explants were planted on MS media with different 2,4-D concentrations (1;2;3 ppm), 0,5ppm IBA+0,5ppm BAP; 0,5ppm IBA+1,0 ppm BAP; and 1,0 ppm IBA+0,5 ppm BAP, each with 15 repetitions. The result showed that the addition of 2,4-D (1 and 2 ppm) was able to induce callus from Binahong leaves on 3 and 5 days after planting, and also 10 days after planting in the controlled and combination treatment. In the 2,4-D media (1 and 2 pm), the callus produced were watery white and compact, while in the 3 ppm 2,4-D media the callus were white and friable. In the media with a combination of BAP and INA the callus were green and compact. The highest average diameter of the callus after 8 weeks in the 1 ppm 2,4-D media reached 2.07 cm followed by the 2 ppm and 3 ppm 2,4-D media producing a diameter of 1.8 cm. In the combination media (BAP and IBA), the callus diameter was less than 0.3 cm. The highest percentage of callus formed was in the media MS+1 ppm 2,4-D and a combination of MS +0,5ppm IBA+0,5ppm BAP that reached 100%. The lowest was found in the control (MS) which reached only 20%. The optimum growth of callus was at 3 weeks and after that it declined or stayed stagnant. The result of the analysis of variance (ANOVA) showed that there was no significant difference in the media used in this research. Key words: induction, binahong leaf, callus, plant growth

Abstrak Durian (Durio zibethinus, L.) memiliki nilai ekonomis tinggi baik sebagai salah satu komoditas hortikultura yaitu buah untuk konsumsi di pasar lokal maupun untuk ekspor. Salah satu hambatan adalah persediaan bibit yang tidak mencukupi dan metode perbanyakan yang merusak pohon induk dengan karakter unggul. Penelitian ini bertujuan untuk memperoleh metode sterilisasi yang tepat dan media untuk perbanyakan durian secara in vitro. Penelitian dilakukan di Laboratorium Kultur Jaringan dan Kebun Percobaan FMIPA, UNY. Metode yang digunakan dalam penelitian ini adalah induksi menggunakan sitokinin BAP (benzyl amino purin) dalam media MS. Eksplan diperoleh dari bibit durian yang sudah dikecambahkan di polibag dengan media tanah dan kompos. Sterilisasi untuk penanaman dengan teknik kultur jaringan menggunakan detergen, clorox 20% dan 10%, alkohol 70%, dan aquades steril untuk nodia, sedangkan sterilisasi eksplan daun dengan clorox 10% dan 5%. Media yang digunakan adalah media MS (Murashige dan Skoog) ditambah dengan BAP (konsentrasi 2 dan 4 ppm), serta 2,4-D (0.4, 1.0, dan 1.5 ppm). Hasil penelitian menunjukkan penambahan BAP dalam media MS mampu memicu pertumbuhan tunas pada eksplan nodia durian pada konsentrasi 2 dan 4 ppm. Penambahan 2,4-D mampu menginduksi kalus pada daun durian. Pada konsentrasi 1 ppm kalus yang dihasilkan berwarna putih, berair dengan daun yang tidak terlalu menggulung sedangkan konsentrasi 0,4 dan 1,5 ppm menghasilkan kalus hijau dengan daun yang menggulung. Perlu perlakuan media yang lebih bervariasi baik pada eksplan nodia maupun daun untuk menghasilkan planlet melalui kalus atau pembentukan tunas secara langsung. Kata kunci: durian, sterilisasi, BAP, 2,4-D, tunas, kalus Abstract One of the problems that can occur in the development of durian (Durio zibethinus, L.) is the availability of seedlings and the method of propagation can cause over-exploitation of the mother plant. The aim of this research was to obtain the method of sterilization and the right media for in vitro propagation of durian. The research was carried out in the Tissue Culture Laboratory and Experimental Garden Faculty of Mathematics and Science, Yogyakarta State University. The method used in this research was induction using the cytokinin BAP (benzylamino purine) in MS media. The explants were obtained from durian seedlings that were grown in polybags with soil and compost media. Sterilization for the tissue culture technique was done using detergent, alcohol 70%, and clorox (20% and 10%), and also sterile aquadest for nodia, while leaf exsplant sterilization was done using clorox 10% and 5%. The media used were MS (Murashige and Skoog) with BAP (2 dan 4 ppm) for the nodia and also with 2,4-D (0.4, 1.0, dan 1.5 ppm) for the leaf explants. The result showed that the BAP in the MS media was able to induce the growth of shoots from the nodia at concentrations of 2 and 4 ppm. The addition of 2,4-D was able to induce the growth of callus on the leaf explants. Using 1 ppm 2,4-D, the callus was white and transparent and the leaves did not curl so much as in the treatments with 0.4 and 1.5 ppm 2,4-D which caused the leaves to curl. More variation in the treatments or media both for the nodia and leaves explants can be further investigated to produce plantlets via callus induction or direct organogenesis. Key words: durian, sterilization, BAP, 2,4-D, shoot, callus
