Abstract

Lesser yam (Dioscorea esculenta (Lour.) Burkill) tubers have two important roles in conventional cultivation, as the food as well as the propagation material. The stem cuttings technique is reported can not produce tubers, while micropropagation is less efficient due to the need of large capital, experts, and specific tools. The other hand, farmers are less interested in cultivating this commodity. It has been reported that mini tuber sett can be used for propagation, but it has not been able to explain the growth preferences in each part of the tuber and its effect on yield. The research aims to provide information about the growth preference of lesser yam seedlings from different planting materials and planting techniques and their effects on yields. The research was carried out in Research Center for Biology, LIPI, Cibinong. The experiment was arranged based on split plots with tubers (apical and basal parts) as the main plot and planting position (vertical and horizontal) as subplots. Each treatment was replicated 3 times, with 5 samples for each replication. The results revealed that the apical part produced better shoots and roots than the basal section. The apical dominance of the lesser yam tuber was very high. It is herefore buds that form in the apical tended to grow faster. This section also produced tuber with a better character. With this information, farmers recommended to use planting materials from the apical part of the tuber with horizontal planting position.

Abstract

Ganyong merupakan tanaman yang sederhana dan potensial sebagai sumber karbohidrat, sehingga sangat layak untuk dikembangkan. Kandungan kabohidratganyong dibandingkan kandungankabohidrat lebih tinggi dari umbi kentang. Ganyong memiliki variasi morfologi yang luas dalam bentuk tanaman tinggi, warna daun, panjangdan lebar, warna dan bentuk ubi variasi kandungan kimia dalam umbi ganyong, sehingga diperlukan seleksi berdasarkan fenotipe untuk memperoleh varian dari ganyong dengan produktivitas tinggi. Ganyong adalah tanaman yang biasanya tumbuh pada daerahnaungan seperti di bawah pohon namun di sisi lain kemampuan pertumbuhannya belum diteliti . Penelitian respons pertumbuhan ganyong 4 varian dalam kondisi iklimmikro yang berbeda telah dilakukan di Laboratorium Macropropagation, Botani Divisi, CSC. Penelitian dilakukan dalam Rancangan Acak Kelompok Faktorial yang terdiri dari3 faktor di mana faktor 1 adalah shading intensitas: 0% (tanpa naungan), 50% dan intensitas varian ganyong 70%), faktor 2 adalah ganyong varian (merah, pink, hijaudan putih) sedangkan faktor ke-3 adalah waktu panen (9 dan 11 bulan).Hasil penelitian menunjukkan bahwa setiap faktor yang merupakan bayangan intensitas, varian danwaktu panen berpengaruh nyata terhadap pertumbuhan dan produksi ganyong. Intensitas naungan terbaik adalah 50% yang secara signifikan berbeda dari 0% dan 70% intensitas naungan dalam hal jumlah tunas, berat segar dan berat kering daun dan berat batang, panjang umbi, bobot segar dan kering umbi. Putih varian dari ganyong prodused terpanjang ukuran umbi, bobot segar tertinggi daun dan batang, highst berat segar dan kering umbi dibandingkan dengan varian lain, bahkan dengan 11 bulan waktu panen mengakibatkan umbi tertinggi, berat kering tertinggi umbi, dibandingkan dengan 9 mounths panen. Kombinasi terbaik dari pengobatan adalah putih ganyong varian, 50% perlakuan yang diberikan adalah pada varian ganyong putih dengan intensitas.naungan 50% dan waktu perlu 9 bulan mengakibatkan produksi siknifikan seperti diameter umbi terbesar (4,8 cm), berat segar dan kering umbi highst dari 8454 g dan 1134 g / tanaman masing-masing. Kandungan kimia umbi dipengaruhi oleh varian dari ganyong dan waktu panen. Kandungan karbohidrat paling tinggi ditemukan pada9 waktu panen mounth, sedangkan kandungan serat, lemak dan protein paling tinggi ditemukan pada waktu panen 11 bulan.

Abstract

Picrasma javanica is one of the medicinal plants that has an anti malaria potency,it is belonging into Simaroebaceae family. The aim of this research is to know the effect of GA3 on broken dormancy of P. Javanica seed after storaged in the various temperature to enhance and increased seed germination. The experiment was carried out in the Macropropagation Laboratory, Cibinong Science Center, Research Center for Biology,LIPI, using a Complete Randomized Design with two factors in three replication.The first factor is condition of storage i.e room (28 ± 10 C, RH 80%), incubator (200 C,RH 90%), incubator ( 50 C, RH 95%) dan deep freezer (- 200 C, RH ). The second factor is long of storage i.e. 1,2,3,4,5 and 5 months. GA3 100 ppm was used for broken seeddormancy. The result showed that there was no interaction between temperature and long of storage. GA3 solution can be broken on seed dormancy before and after storage in the various temperature excepted in deep freezer ( – 200 C, RH 65%), there are no seed germinate since 1 month storage. P. javanica seed that storage in incubator 50 C is the best method and after 5 months the germination percentage is still high (73,3%) with GA3 but only 18,33% without GA3. On the other treatments the germination percentage is less than 50%. The highest germination value (14,1) that was recorded in the seeds that storage in incubator (200 C, RH. 95%).Key words: GA3, dormancy, temperature, long of storage, seed , P. javanica

Abstract

Dyera costulata, usually called as jelutung is belonging into Apocynaceae family.This plant is a potential plant species that has good prospect, especially for timberand latex production. However the seedling grows slowly. The experiment wascarried out in greenhouse, Treub Laboratory, Botani Division, Centre Research forBiology-LIPI, Bogor, using a Factorial Completely Randomized Design with treemain factors in five replications. The first factor is phase of transplant i.e. seedlingwith closed cotyledon, seedling with opened cotyledon, seedling with two firstleaves. The second factor is growth medias i.e. soil, soil+compost (1:1), soil+huskof rice (1:1), soil+compost+ soil+husk of rice (1:1:1), compost+ soil+husk of rice(1:1). The third factor is mycorrhiza i.e. 0, 2, 4 and 6 g/pot The result showed thatthe transplant phase had significant effect on the seedling growth. The best oftransplant phase is seedling with two leaves which has 100% survival, seedlingheight 8.57 cm and number of leaves 5.07 . Mycorrhiza treatment no significanteffect on the seedling growth until 5 months after planting. Growth medias hadsignificant effect at number of leaves. Therefore it is recommended the best mediafor seedling growth are are of soil+ soil+husk of rice (1:1) , or soil+compost + huskof rice = 1:1:1. There was no interaction effect of transplant phase, mycorrhizaand growth media.

Abstract

The research on the effect of planting space treatment on the growth and yield of three accessions of local maize from Maros, Sulawesi Selatan was carried out at the Experimental Garden of Research Center for Biology LIPI, Cibinong on May ? August 2012. The research study was arranged by Factorial in Randomized Completely Block Design with 2 factors and 4 replications, each replication with 10 plant samples. The first factor was accession of pulut local maize (sticky rice maize) with 3 levels factor i.e. Snack Pulut, Rice Pulut and Hybrid Pulut. The second factor was planting space treatment with 3 levels factor i.e. planting space of 100x20 cm, 80x20 cm and 60x20. The treatment of accession was significantly on the vegetative growth of Pulut corn. Accession Rice Pulut growth was the fastest (116.3 cm plant height, 11.5 number of leaves), compared to Snack Pulut (91.2 cm plant height, 7.6 leaves), and accession Hybrid Pulut (111.9 cm height, 8.2 leaves). All of accession showed flowering (70-90 %) at 7 weeks after planting. Accession of Snack Pulut showed fruiting (90%) faster than Hybrid Pulut (80%), and  Rice Pulut (20%). Accession Rice Pulut showed the highest production compared to Snack Pulut and Hybrid Pulut, but has the longest harvest (12 weeks). Accession of Snack Pulut was the fastest harvesting (9 weeks), followed by Hybrid Pulut (10 weeks). The planting space treatments were not significantly different on the growth and production of sticky rice maize, so tight spacing (60x20 cm) may be used to increase yield.  Key words: Planting space, growth, yield, accessions, local maize, Maros

Abstract

Rosela (Hibiscus sabdariffa L) merupakan salah satu jenis tanaman herba tahunan yang dibudidayakan untuk diambil bunganya. Bunga rosela pada umumnya berwarna merah tua kehitaman dan tidak berbau harum. Dikarenakan kandungan nutrisi serta senyawa kimia pada bunga rosela yang sangat baik untuk kesehatan, masyarakat luas mengolah bunga rosela menjadi berbagai macam produk minuman seperti teh dan sirup serta dapat juga digunakan sebagai bahan pembuatan produk makanan. Rosela tentunya juga berpotensi untuk dapat dikembangkan sebagai tanaman budidaya di lahan kering. Namun demikian, lahan kering yang saat ini luasannya mencapai lebih dari 191 juta ha di Indonesia merupakan salah satu faktor pembatas bagi peningkatan produktivitas tanaman. Hal ini dikarenakan cekaman kekeringan di lahan tersebut dapat menekan pertumbuhan dan perkembangan tanaman sehingga menurunkan hasil produksi tanaman. Untuk itu, penelitian mengenai penggunaan pupuk terhadap pertumbuhan rosela dibawah pengaruh stres kering dilakukan untuk mengetahui pengaruh pupuk dalam mengatasi cekaman kekeringan pada media tumbuh tanaman rosela. Penelitian ini dilakukan dengan menggunakan RAL (Rancangan Acak Lengap) faktorial dengan 2 macam faktor perlakuan yaitu, komposisi pupuk dan perlakuan stres kering, dengan 3 kali pengulangan. Perlakuan pemberian pupuk terdiri dari 3 taraf, yaitu hanya tanah saja, tanah + pupuk kompos (1:1), dan tanah + pupuk kompos + pupuk kandang (2:1:1). Perlakuan stres kering diberikan dalam bentuk interval penyiraman dan terdiri dari 4 taraf, yaitu disiram setiap hari, setiap dua hari sekali, setiap tiga hari sekali, dan setiap empat hari sekali. Pengamatan terhadap indeks toleran dan indeks sensitivitas tanaman rosela terhadap stres kering menunjukkan bahwa perlakuan pemberian pupuk organik berkolerasi positif terhadap peningkatan pertumbuhan tanaman rosela dibawah pengaruh cekaman kekeringan.
