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 (

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

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

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.

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

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

Increasing corm production of iles-iles (Amorphophallus muelleri Blume) through genetic improvement is important for increasing farmers’ income. However, the study on variety development is rarely reported. Here, yield evaluation of the second growing period was conducted at IPB Experimental Station Leuwikopo Farm, Bogor, Indonesia (-6.5647419, 106.7220331, 17.25z) from August 2017 to July 2018 in order to select candidate clone with high corm production. One-year-old corms of 21 F1 accessions were planted under 55% shading net with four replications. The parent population was set as a control. Results showed that accessions exhibited variation in corm size. The parent population produced corm ranged 622.3-908.3 g in weight (on average 764.2 g). The pooled accessions produced corm 180.7-1527.5 g in weight, corm diameter 71.0-145.8 mm, and corm height 46.6-87.6 mm. Nine accessions produced 5.91-99.88% higher average corms weight than the parent, i.e., BKB, BS, CF, CK, CR, DPG, DPP, SBM, and SHJ. Based on 30% as the basis of corm weight improvement, we concluded that five accessions, i.e., CK, CR, DPG, DPP, and SBM as prospective candidate clones. These accessions could be further evaluated in the third growing period to select best candidates of new variety of A. muelleri.Keywords: Agamosporous, Araceae, breeding strategy, new variety, productivity

Bambara groundnut seeds often show unsynchronized and slow germination even though on newly harvested seeds. This might be due to the presence of seed dormancy. Therefore, the objective of this research was to obtain the information on seed dormancy and germination behaviour of bambara groundnut seeds during desiccation. The experiment was arranged in a nested design. Dormancy breaking treatments (untreated, mechanical scarification, soaking in 1% KNO3 for 2 hours, mechanical scarification followed by KNO3 soaking) were nested in each of the desiccation levels (fresh seeds with 54.7% moisture content (mc), desiccated seeds with 44.4%, 18.0%, 15.4%, and 12.1% mc). The results showed that newly harvested seeds were in dormant state. Seed desiccation did not increase the intensity of seed dormancy, even resulted in an increase in field emergence (at 30 days after planting) from 43.9% in fresh seeds to around 70% in dry seed (12-15% mc). Seed desiccation (from 44.4% mc to 12.1% mc) increased the field emergence, although it was inadequate to break the dormancy completely. Meanwhile, seed desiccation tended to increase the GA/ABA ratio, but the seed permeability was decreased. The fact showed that seed desiccation reduced the intensity of dormancy of bambara groundnut seed, therefore, it is suggested to modify the drying method in order to accelerate the increasing of GA/ABA ratio while keeping the testa permeable.

Tujuan penelitian ini adalah untuk mempelajari pengaruh priming dalam mempertahankan vigor benih kacang panjang selama dalam penyimpanan. Perlakuan priming yang dilakukan adalah perendaman benih dalam air, KNO3, CaCl2, asam askorbat, dan pelembapan diantara kertas selama dua jam. Perlakuan priming menyebabkan peningkatan kadar air benih hingga sekitar 9%, sedangkan perlakuan pelembapan diantara kertas hanya meningkatkan kadar air 1-2 % dibanding kontrol. Setelah selesai perlakuan, benih dikeringkan kembali hingga kadar air 12-13% lalu disimpan di ruang kamar(26-30.8 °C; RH 68-77 %) dan AC (±20 °C; RH ±50%) menggunakan plastic polipropilen (tebal 0.08 mm). Perlakuan priming mampu mempertahankan indeks vigor dan kecepatan tumbuh sampai dengan 15 minggu penyimpanan baik pada penyimpanan ruang AC ataupun kamar. Perlakuan perendaman dalam air dapat menjadi pilihan terbaik sebagai perlakuan benih sebelum simpan karena murah dan mudah dilakukan serta memberikan hasil yang baik.
