Abstract

Tanaman aren merupakan tanaman serbaguna. Produk utama dari tanaman aren adalah nira yang disadap dari bunga jantan. Tandan bunga betina menghasilkan buah sebagai sumber benih. Nira aren memiliki nilai ekonomi tinggi jika diolah menjadi gula sebagai produk utama. Penelitian ini bertujuan untuk mengetahui pengaruh penyadapan tandan bunga jantan dan posisi tandan bunga betina terhadap mutu benih aren. Penelitian dilakukan pada bulan Januari sampai April 2012, di Laboratorium Ilmu dan Teknologi Benih Leuwikopo, Departemen Agronomi dan Hortikultura, Institut Pertanian Bogor. Penelitian dilakukan dalam bentuk percobaan faktorial dengan dua faktor dan empat ulangan menggunakan Rancangan acak lengkap (RAL). Faktor pertama adalah penyadapan tandan bunga jantan (T) yang terdiri tandan bunga jantan disadap (T1) dan tandan bunga jantan yang tidak disadap (T2). Faktor kedua adalah posisi tandan bunga betina (P), yaitu tandan pertama (P1), tandan ketiga (P2) dan tandan kelima (P3) dari pucuk. Hasil penelitian menunjukkan bahwa pohon yang tandan bunga jantan disadap maupun tidak disadap dapat dijadikan sebagai sumber benih dengan daya berkecambah sekitar 79,77-84%. Benih berukuran kecil yang berasal dari pohon yang disadap memiliki mutu fisiologi yang tinggi. Oleh karena itu, petani dapat menggunakan buah dari pohon yang disadap sebagai sumber benih. Kata kunci: Benih, aren, penyadapan, tandan bunga jantan, letak tandan bunga betina.ABSTRACTThe Seed Quality of Sugar Palm Caused by Tapping of Male Inflorescences and Position of Female Inflorescences (Arenga pinnata (Wurmb.) Merr.)Sugar palm is aversatileplant. The main product is neera which tapped from themale inflorescences whereas the female inflorescences produce fruit and seeds. The neera then processed into brown sugar which has a high economic value. This research was aimed to study the effect of tapping of the male inflorescences and the position of the female inflorescences on seed quality. The study was conducted from January to April 2012, in the Laboratory of Seed Science and Technology Leuwikopo IPB Bogor Bogor Agricultural University Department of Agronomy and Horticulture. The research was done in factorial experiment with two factors by using completely randomized block design and four replications.The firstfactorwas tapping i.e the male flower was tapped (T1), The male inflosences was untapped (T2) and the second factoris the position ofthe female flower (P) i.e the first (P1), third (P2) and fifth (P3) female inflorences from the top. The result showed both tapped and untapped sugar palm tree can be used as seed source with viability 79.77-84%. Small seeds from tapped trees have a high physiological quality. Trees that were smaller seeds that untapped trees although they were similary of high physiological quality. Therefore farmers can use the seeds of the tree which is tapped as a source seed tapped from the male inflorencences as seed source.

Abstract

Penggunaan true shallot seed (TSS) sebagai bahan tanam masih rendah karena ketersediaannya sedikit dan teknik budidaya belum dikembangkan. Produksi TSS di dataran rendah menjadi alternatif karena sebagian besar bawang merah di Indonesia diproduksi di dataran rendah. Penelitian ini bertujuan untuk meningkatkan mutu TSS di dataran rendah. Penelitian dilakukan di dataran rendah Subang (100 mdpl) dan Laboratorium Ilmu dan Teknologi Benih Institut Pertanian Bogor. Bahan tanaman yang diperlukan adalah umbi bawang merah varietas Bima yang divernalisasi tiga minggu pada suhu 10°C. Rancangan percobaan menggunakan rancangan acak kelompok dua faktor yang diulang empat kali. Faktor pertama adalah dosis P2O5 (0, 100, 200, 300, 400 kg ha-1) dan faktor kedua adalah dosis K2O5 (0, 50, 100, 150, 200 kg.ha-1). Hasil penelitian menunjukkan bahwa pemberian P dengan dosis 400 kg ha-1 mampu meningkatkan  daya berkecambah, indeks vigor dan potensi tumbuh maksimum TSS.  Peningkatan pupuk K tidak berpengaruh terhadap semua parameter pembungaan kecuali jumlah bunga per tanaman dan persentase pembentukan kapsul. Pemberian 50 Kg K2O ha-1 mampu meningkatkan jumlah bunga per tanaman hingga 70.9 kuntum, sementara pemberian 200 kg K2O ha-1 mampu meningkatkan  persentase pembentukan kapsul sebesar 54.82%. Kombinasi pemberian dosis 400 kg P2O5 ha-1 dan K 200 Kg ha-1 mampu meningkatkan daya berkecambah sebesar 74.7 % dan indeks vigor dengan nilai maksimum sebesar 92%, sedangkan dosis 200 Kg P2O5 ha-1 mampu meningkatkan potensi tumbuh maksimum TSS sebesar 64%.

Abstract

Factors which influence decline in seed vigor during storage are temperature and humidity in the storage room, as well as utilized storage medium. This study was aimed to obtain information on the effect of different storage media on its ability to maintain moisture content (MC) and electrical conductivity (EC) of oil palm seeds in an AC controlled storage condition. The study was conducted using complete randomized design with single factor, i.e. storage medium with three levels: single polypropylene (PP) plastic (M1), double PP (M2), and vacuum plastic (M3). Results of the experiment showed that the AC controlled condition caused decreases in seed MC at different rates between treatment levels where measured water loss was 11.47% on M3, higher than those of M1 (8.13%) and M2 (6.18%). Even though the three levels indicated decreases on seed MC, the final MC (13.8%) was still higher than that which is allowed (10-12%) for oil palm seed storage, as EC value (2,69 – 3,04 µS.cm-1.g-1) at the end of the trial. For short period (104 d) storage, both parameters showed positive correlation with 0.77 coeffsien of correlation value.

Abstract

One of the major constraints in Jatropha oil production is asynchronous fruit ripening, hence harvesting needs to be carried out accordingly which lead to drudgery. Therefore, an experimental study on the use of plant growth regulators was designed to induce synchronous fruits ripening. The study was conducted at the Jatropha Indocement Tbk PT Citeurep from January-June 2010. Test seed vi-ability and vigor was conducted in greenhouse Leuwikopo Experimental Garden, Bogor Dramaga. While the oil content test was conducted in the Department of Industrial Technology Testing Laboratory of Agricultural IPB. This research was conducted in two phases. In the first stage used factorial randomized block design. The first factor is the dose etephon 200,400,600,800, 1000 and 1200 ppm while the second factor is the time of application etephon ie 40 and 45 days after anthesis. The second phase also uses a factorial randomized block design. The first factor is the dose etephon 0,100,200, 300 and 400 ppm, while the second factor is the time of application ie 40 and 45 days after anthesis. Application of etephon at 200 ppm on 40 day after anthe-sis shorten the fruit maturation hence more synchronous fruit ripening in rainy season, but not in dry season when fruits ripened synchronously. The quality of the seed and kernel were not affected by etephon application.  Keywords: Jatropha curcas, growth regulator, etephon, simultaneity of fruit maturity

Abstract

Buah rotan jernang merupakan hasil hutan bukan kayu bernilai ekonomi tinggi karena pada eksokarp buah terdapat resin. Buah rotan jernang dipanen sebelum benih mencapai masak fisiologis untuk mendapatkan resin kualitas tinggi sehingga tanaman tidak dapat meregenerasi secara alamiah dan rotan jernang di habitat alami semakin berkurang. Kendala dalam ketersedian benih bermutu adalah perkecambahan lama dan pertumbuhan bibit tidak seragam. Tujuan penelitian adalah untuk mendapatkan metode perkecambahan yang lebih cepat dan seragam, mempelajari proses perkecambahan, dan mengembangkan metode uji daya berkecambah. Percobaan pertama menggunakan RAL dua faktor. Faktor pertama adalah pencongkelan operkulum, terdiri atas dua taraf yaitu benih utuh dan benih tanpa operkulum. Faktor kedua adalah perendaman benih terdiri atas tiga taraf yaitu kontrol, perendaman menggunakan aquades dan KNO3 0,2%. Percobaan kedua menggunakan RAL satu faktor yaitu media perkecambahan terdiri atas media pasir dan cocopeat. Data dianalisis menggunakan SAS 9.4 dan diuji lanjut menggunakan DMRT pada taraf kepercayaan 5%. Pencongkelan operkulum dan tanpa perendaman dapat meningkatkan indeks vigor dan kecepatan tumbuh. Proses perkecambahan benih rotan jernang (benih tanpa operkulum) terdiri atas empat tahap yaitu terbentuk tangkai kotiledon, kotiledon ligule, akar dan daun. Hitungan pertama dan hitungan terakhir uji daya berkecambah adalah 72 dan 104 hari setelah tanam. Kriteria kecambah normal adalah panjang plumula minimum ±15 mm, akar berkembang dengan sempurna yaitu terdapat akar primer dan akar sekunder.  Media terbaik untuk perkecambahan benih rotan jernang adalah pasir.

Abstract

One of the problems for phosphate fertilizing in ultisol soil is Al and Fe bounding and could be overcome by phosphate solubilizing bacteria activity.This study aimed to obtain the best dose of phosphate fertilizer with phosphate solubilizing bacteria for the production of upland rice seeds of the UBB1 PBM variety (Bangka Belitung University red rice 1) and its effect on seed quality. The research was carried out at the Research and Experimental Gardens – Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung, from August to December 2020. The design used was a split plot design, the main plot was phosphate solubilizing bacteria (treatment and control), and the subplots were fertilizers. phosphate (P1– quarter dose, P2– half dose, P2–three-quarter dose, P4– full dose). Seeds produced in the field were tested in the laboratory for viability and vigor. In the field, phosphate solubilizing bacteria (Burkholderia sp) can replace half the dose of phosphate fertilizer. This was indicated by the seed weight of plant-1 which did not differ between full dose + control and half dose + treatment. This fact was also identified in the viability and vigor of the seeds in laboratory testing. There was no significant difference in germination rate and vigor index between the two treatments. This finding shows that phosphate solubilizing bacteria can be applied for efficiency of phosphate fertilization and guaranteeing seed production and seed quality

Abstract

The current method to break oil palm seed dormancy is the dry heat method which requires approximately 90 days for seeds to germinate with an average germination percentage. Therefore, hastening the process with a higher ratio of germinated seeds becomes necessary. This experiment aims to hasten and increase germination percentage by applying fine bubble water during the dormancy-breaking process. A seed lot derived from one bunch as replication is divided into two sets where fiber plugs from one of the sets are removed while the other set remains intact. Each set was re-divided into six experimental units soaked with tap water or fine bubble water for 1 to 3 days. The result showed that applying fine bubble water provided a better germination rate than tap water treatments. However, the total germination percentage between all treatments does not differ significantly. The germination peak of oil palm seed in the fine bubble water treatments occurred on the 26th day, 8 days faster than in the tap water treatments. The occurrence showed the potential use of fine bubble water application during dormancy breaking using the dry heat method.

Abstract

The somatic hybridization between Mandarin Satsuma (Citrus unshiu Marc.) and Siam Madu (Citrus nobilis Lour.) is expected to produce progenies having sweet seedless fruit. The research was aimed to study flowering biology, fruit and seed development to identify parthenocarpic lines derived from somatic hybridization. The research was carried out at Pacet Experimental Station of ICABIOGRAD, Cianjur, West Java (1150 m asl), during August 2019-July 2020. The research materials were 15 citrus lines derived from somatic hybridization between Mandarin Satsuma and Siam Madu, of which 5 plants (± 2 years old) per line were prepared. Observation was carried out on flowering phenology, flower morphology, fruit development, pollen viability, and stigma receptivity. Seedless fruits from un-pollinated, selfpollinated, and cross-pollinated flowers of each line were investigated. The results showed that flower morphology of the 15 citrus lines varied in the number of petals, flower diameter, pistil length relative to the stamen, and number of stamen. The development from bud emergence to fruit ripening also varied among and within lines, ranging from 212 to 316 days. Among the lines, FS 25 showed a stronger character towards stimulative parthenocarpy. FS 84 and FS 89 were potential sources of pollen (pollenizer) to produce seedless fruits.
