Abstract

Kapulaga jawa (Amomum compactum Sol ex. Maton) merupakan spesies yang berbeda dengan Elettaria cardamomum (L.) Maton. Tanaman ini biasanya diperbanyak secara vegetatif namun tetap diperlukan benih botani. Benih kapulaga memiliki lapisan testa yang keras dan memerlukan waktu yang lama untuk berkecambah. Percepatan perkecambahan biji dapat dilakukan dengan menggunakan media perkecambahan yang tepat dan memberikan perlakuan pendahuluan yang dapat mengurangi faktor penghambat perkecambahan. Penelitian ini bertujuan untuk mendapatkan media perkecambahan yang tepat dan perlakuan pendahuluan yang efektif untuk mempercepat perkecambahan benih kapulaga. Penelitian ini menggunakan rancangan acak kelompok lengkap petak terbagi dengan perlakuan jenis media perkecambahan sebagai petak utama, perlakuan pendahuluan sebagai anak petak, dan tiga kali ulangan. Evaluasi penghitungan pertama dilakukan pada hari ke-24 setelah tanam dan penghitungan kedua pada hari ke-51 setelah tanam. Pada penelitian ini tidak ditemukan adanya perlakuan pra-tanam yang mampu memacu perkecambahan. Media cocopeat merupakan media terbaik dibandingkan dengan media pasir dan media tanam campuran arang sekam: sabut kelapa : kompos (1:1:1) pada parameter daya berkecambah 80.5%, kecepatan tumbuh 3.11% etmal-1, indeks vigor 35.2%, dan benih segar tidak tumbuh 1.3%. Interaksi antara perlakuan media cocopeat dan perlakuan pra-tanam dengan perendaman dalam air 50 °C selama 30 menit memberikan waktu berkecambah paling singkat yaitu rata-rata waktu berkecambah 25.0 hari. Kata kunci: cocopeat, dormansi, pembibitan, tetrazolium, viabilitas

Abstract

Sorgum varietas Samurai memiliki tinggi tanaman mencapai 198.7 cm, sehingga mudah rebah serta menyulitkan pemeliharaan dan pemanenan. Aplikasi paklobutrazol bertujuan menghambat pertumbuhan tinggi tanaman serta meningkatkan kualitas fisiologis benih. Penelitian ini bertujuan menentukan konsentrasi dan waktu aplikasi paklobutrazol yang tepat untuk menghasilkan benih sorgum bermutu tinggi. Penelitian dilaksanakan dari April 2023 hingga Februari 2024 di kebun percobaan Lewikopo. Konsentrasi paklobutrazol yang diberikan adalah 1000 ppm dan 1500 ppm, waktu aplikasi pada umur 5 dan 7 minggu setelah tanam.  Mutu benih diuji pada saat panen dan setelah penyimpanan (1, 2, dan 3 bulan). Aplikasi paklobutrazol 1000 ppm pada umur 5 minggu setelah tanam merupakan perlakuan yang tepat untuk menekan pertumbuhan tinggi tanaman. Perlakuan dosis paklobutrazol ini menghasilkan peningkatan yang signifikan pada diameter batang, panjang daun, dan lebar daun serta mutu benih yaitu daya berkecambah dan bobot kering kecambah normal. Aplikasi paklobutrazol secara nyata menurunkan kandungan giberelin dalam benih. Aplikasi paklobutrazol 1500 ppm pada 7 minggu setelah tanam menurunkan mutu benih setelah simpan berdasarkan tolok ukur daya berkecambah, kecepatan tumbuh, dan potensi tumbuh maksimum. Kata kunci: daya berkecambah, giberelin, kecepatan tumbuh

Abstract

Pinto peanut (Arachis pintoi Krap & Greg.) is a legume that is usually used as a cover crop, bio mulch in fruit and vegetable plantations, ornamental plants, and animal feed. Pinto peanut has many benefits; through the symbiosis with rhizobacteria they can fix nitrogen, as ground cover can reduce the risk of landslides, inhibit weed growths, and is a source of nectar for bees. Arahcnis pintoi can be propagated vegetatively or generatively, but generative propagation is hard to conduct in the tropics because it takes a long time for the plants to produce seeds. Our study was conducted to determine the effect of GA3 application on seed production of A. pintoi. The experiment was arranged in a single factor randomized complete block design with GA3 concentration of 0, 75, 150, 225, and 300 ppm. An orthogonal polynomial test was conducted to determine the effective concentrations for GA3 on seed formation and seed viability. Harvested seeds were stored for 1 month, then sown on sand medium; the seeds were soaked in 1% KNO3 solution to break seed dormancy prior. Our study showed that the GA3 effective concentration range from 130.69 ppm to 137.16 ppm, indicated by the increase the number of flowers at 105, 120, 135, and 150 DAT up to 28.59% compared to control. GA3 at 126.80 ppm can also increase the number of harvested pods by 18.16%. The effect of GA3 on vegetative growth was shown by the increase in the growth of new individual plants concentration, i.e. 53.25 new individual plant with GA3 application of 141.88 ppm.

Abstract

There are phenolic compounds in sarcotesta of papaya seed which can act either as inhibitor or as antioxidant.  The objective of this experiment was to study the effect of sarcotesta and seed moisture content on total phenolic content and seed longevity of papaya seed.  The experiment was conducted in November 2004 - May 2005, at Bogor Agicultural University, by using papaya seed (IPB-1) harvested from Center for Tropical Fruit Studies orchard in Bogor. In this study, seeds were dried in the absence and presence of sarcotesta until 11-12% and 6-7% moisture content (mc).  After drying, seeds were packed in sealed plastic bag and stored in ambient room until 0, 3, 6, 9, 12 and 15 weeks. Seed viability and total phenolic compound were evaluated every 3 weeks.  Total phenolic content of seed with sarcotesta was higher (> 327mg/100g dry weight) than the seed without sarcotesta (

Abstract

The objective of this research was to study the influence of invigoration on yard-long bean seed germination under salinity stress. The research was conducted at Seed Science and Technology Laboratory, Department of Agronomy IPB from September to December 2007. Seed of two yard-long bean (Vigna unguiculata Hask. ssp. sesquipedalis) varieties, i.e. 777 and Landung Super, were used to investigate the effects of invigoration treatments, i.e. water soaking, sand priming, sawdust matriconditioning, osmoconditioning with CaCl2, NaCl, KCl and KNO3, under salinity 1.0% NaCl (w/v) stress condition. Sand priming and water soaking treatments significantly enhanced the germination percentage, speed of germination and dry matter of normal seedling under the salinity stress condition. Germination percentage of seed with sand priming was 33.33% higher than tgat of control, and germination percentage of seed with water soaking was 28.66% higher than that of control. The result  suggested that sand priming and water soaking were the effective methods to improve yard-long bean seed germination under salinity stress condition.   Key words: invigoration, salinity stress, sand priming, water soaking, yard-long bean   seed

Abstract

Improved seed longevity by seed drying and application of  phenolic compound as natural antioxidant is the topic of this research. In many cases the sensitivity of papaya seed to drying is being the limit factor because of desiccation injury or induced dormancy. There is phenolic compound on the sarcotesta surrounding papaya seed which may act either as antioxidant or as germination inhibitor. The effect of sarcotesta and seed drying on viabillity and dormancy was studied. The experiment was conducted in July - October 2004, located at Bogor Agricultural University, used papaya seed (IPB-1) which harvested from Pusat Kajian Buah Tropika (PKBT) farm in Bogor. In the last study, seed was dried in the absence and presence of sarcotesta until 11-12% and 6-7% moisture content (mc). After drying, seed viability was measured by tetrazolium test.  The hardness of seed was also measured using penetrometer.  Seed germination was tested by (1) soaking on 10% KNO3, (2) scarification on water using  electrical stirrer, (3) soaking on 10% KNO3  with scarification using electrical stirrer, (4) scarification on the  hot water (50oC) followed by soaking on 10% KNO3.   In the absence of sarcotesta, the viability of 6-7% mc seed was as high as 11-12% mc seed. There was neither viability reduction nor induced dormancy. Whereas in the presence of sarcotesta, there was also no viability reduction but the dormancy was induced. The dormancy of seed with 11-12% mc was longer than seed with 6-7% mc. Scanning electron microscopy images showed that sarcotesta was removed by cleaning treatment before drying. On the contrary, sarcotesta was not completely removed from the seed and became more impermeable when cleaning was done after drying.This research can not suggest the most effective  pre-treatment to break the dormancy. The mechanism of the dormancy is discused.   Key words: Carica papaya L., seed drying, sarcotesta, seed viability, seed dormancy

Abstract

The objective of this research was to improve seed vigor, plant growth, and productivity of black soybean through seed invigoration treatment. The experiment was arranged in split-plot design. As the main plot, there were two black soybean varieties (Detam-1 and Detam-2) and as the sub-plot there were seed invigoration treatments applied (untreated control, matriconditioning, biofertilizer, matriconditioning plus biofertilizer). Matriconditioning was conducted using ratio of seeds to carrier (rice hull charcoal) to water of 9:6:7 (w/w/v) for 12 h in ambient room. For biofertilizer treatment, biofertilizer (consists of nitrogen-fixing bacteria, phosphate-solubilizing bacteria, fungicide-producing bacteria, and growth-regulator-producing endophytic bacteria) was applied just before planted by mixing seeds with 6.25 g biofertilizer (kg seeds)-1 and small amount of water. Matriconditioning plus biofertilizer was conducted by integrating the biofertilizer in matriconditioning. Results of the experiment showed that matriconditioning or matriconditioning plus biofertilizer improved germination percentage and rate of germination. Biofertilizer or matriconditioning plus biofertilizer improved vegetative growth. Although there was no significant effect of invigoration treatment on productivity, biofertilizer treatment produced seeds 15% higher than control, and matriconditioning treatment produced seeds 13% higher than control. Viability and vigor of harvested seeds were not affected by invigoration treatments, however, Detam-2 had higher viability and vigor than Detam-1 based on germination percentage, index vigor, and rate of germination.

Abstract

ABSTRACTBasil (Ocimum basilicum L.) is cultivated in many countries as vegetable crop, and as herbal medicine or pesticide for mosquito larvae, but there is limited information on its seed viability. Three experiments were conducted at Seed Science and Technology Laboratory Departement of Agronomy and Horticulture IPB from January to June 2011. Experiment one tested viability of basil seeds with different maturation obtained from different fruit maturity and drying treatment. Experiment two stored basil seed for 12 weeks in ambient condition and tested seed viability weekly. In experiment three, two seed lots that have been stored for 2 and 14 weeks in ambient condition were invigorated with GA3 1,000 ppm and KH2PO4 1.5% and light treatment 820 lux m-2. It was revealed that basil seed was physiologically mature at 44-49 days after flowering with 12.5% moisture content and low viability of 34.0%. After-ripening period of basil seed was two week where the seed viabilty increase to 56.7%. Seed viability did not significantly change during 12 weeks stored in ambient condition. Maximum viability of basil seed (64.34-66.52%) could be achieved by invigoration treatment  with GA3 1,000 ppm and light treatment 820 lux m-2.Keywords: dormancy, germination, seed maturity, vegetable crop

Abstract

The objective of this experiment was to study the influence of post-harvest storage and storage period to seed viability. The research was conducted in the Laboratory of Seed Science and Technology and the green house at Leuwikopo IPB Darmaga, from February until August 2007. The experiment used split-plot design with three replications. The main plot was seven periods of storage: 0, 3, 6, 9, 12, 15, and 18 weeks. The sub plot was the period of post-harvest maturation storage (use the fruits with 30-40% yellow coloured): 0, 2, 4, 6 days post-harvest storage, and control fruits that ripe on the tree (with 80-90% yellow coloured). The control fruits have the best seed viability and vigor. Viability of seed from fruits with 0, 2 and 6 days post-harvest storage was significantly less than that of control. Seed from four days post-harvest storage have same viability as control. Post-harvest storage can improve physiological seed quality on the seed that must be harvested before the time of physiological maturity, especially four days post-harvest storage
