Turi is one of horticultural plant has many benefits but its existence is increasingly limited. Development of turi should begin with the procurement of high quality seed. Test power germinated is one test used to detect the seeds. Germination of seed resource test procedure is not yet well known as turi methods break dormancy, germination substrates that are effective, as well as the first count and final count so that research needs to be done. The research was carried out in a Laboratory Storage and Seed Quality Testing of IPB in May-September 2017. That test results obtained from the seeds of turi germination for 21 days is the first count on day 6 and final count on day 8. The most maximum germination substrate is merang paper then filter paper. Turi also have dormancy so need to be given preferential treatment so that the dormancy was broken and easy to germinate. Scarification (sandpaper) method is the best method in breaking seed dormancy of turi. ABSTRAKTuri merupakan salah satu tanaman hortikultura yang memiliki banyak manfaat namun keberadaannya semakin terbatas. Pengembangan tanaman turi harus dimulai dengan pengadaan benih yang bermutu tinggi. Uji daya berkecambah adalah salah satu pengujian yang digunakan untuk mendeteksi benih. Prosedur pengujian daya berkecambah benih turi belum banyak diketahui seperti metode pematahan dormansi, substrat perkecambahan yang efektif, serta first count dan final count sehingga perlu dilakukan penelitian. Penelitian ini dilaksanakan di Laboratorium Penyimpanan dan Pengujian Mutu Benih IPB pada bulan Mei-September 2017. Hasil pengujian yang diperoleh dari pengecambahan benih turi selama 21 hari adalah hitungan pertama (first count) nya pada hari ke-6 dan hitungan kedua (final count) pada hari ke-8. Substrat perkecambahan yang paling optimum untuk mengecambahkan benih turi adalah kertas merang kemudian kertas saring. Turi juga memiliki dormansi sehingga perlu diberikan perlakuan supaya dormansinya patah dan mudah untuk berkecambah. Metode skarifikasi (pengamplasan) adalah metode terbaik dalam mematahkan dormansi benih turi.Kata kunci: amplas, hitungan kedua, hitungan pertama, kertas merang Bul.

Cananga odorata (Lam.) Hook.f. & Thomson is one of the essential oils producing plants that have many benefits for humans. However, there is little information about the floral morphology and anatomy of C. odorata. The aim of this study is examining the floral morphology and anatomy of C. odorata. The flower morphology (color, shape, and size of the flower) were observed at fresh mature flowers. While, the flower anatomy (pistil, stamen, and ovary) were observed at flower histological samples. The flower was fixed, dehydrated, alcoholized, embedding in paraffin, and stained with safranin-fast green. The results of this study showed that flowers of C. odorata are complete flowers that had 3 green sepals (0.5 – 0.9 cm), 6 – 12 yellowish-green petals (2.5 – 7.2 cm), 8 – 15 dark green pistils (5 – 8 mm), and numerous stamens. The shape of pistils is oval and contains one ovary which has 8 – 12 ovules. The shape of the stamens is elongated oval and contains pollens. The information about the floral morphology and anatomy of C. odorata might enhance the understanding of future studies regarding natural reproduction and cultivation programs.
Moringa (Moringa oleifera Lam.) is a commodity that has high economic value. The increasing demand for moringa needs to be supported by the availability of high quality seeds. Quality seeds were affected by germination and seed storage technology. This experiment aimed to study the optimization germination test of moringa seed and to determine the effect of packaging and different room storage condition on seed viability and vigor during storage period. This research was conducted at the Laboratory of Seed Science and Technology, Bogor Agricultural University and greenhouse, experimental field at Leuwikopo, Bogor Agricultural University Dramaga, from April-October 2016. Optimization germination test consisted of observations for first count and final count and the effect of wing treatment and fruit maturity seed on viability. First count observations was done on 10th day and the final count on 15th day after the germination. This research used in sand method for germination test. During the 6 months storage period, moringa seed stored in aluminum foil and plastic package on the air conditioner (AC) temperature (17-19 °C) and room temperature (27-29 °C) has better water content, viability and vigor than the seed stored in paper package. The seed stored in aluminum foil package has the best average of water content (7,75%), viability (growth potency of 86,22%) and vigor (growth speed of 9,58% KN /etmal), while the use of plastic package has the best average of viability (germination capacity of 82,11%) and vigor (vigor index of 66,83%). The storage at AC temperature mantained water contain, viability and vigor better than room temperature storage.
<p>ABSTRACT</p><p>Identification of fruit and seed characters when they reach physiological maturity is very important to get high qualiy chili seed. The purpose of the research was to study the fruit characters and to determine seed physiologycal maturity of six chili genotipes (Capsicum annuum L.) i.e. Anies 1, Anies 2, Seloka 1, Seloka 2, Seloka 3 and SSP. Characterization was assayed at 32, 35, 38, 41, 44 DAA. Chili seed was taken from two groups of branches, lower branches (2nd-5th branches) and upper branches (6-7th branches). The result revealed that seed physiological maturity was achieved at 38-44 DAA, that was indicated by changes of the fruit color from brown to red (Anies 1) and dark green to red on five others genotipe; maximum seed dry weight, seed viability and vigor. When the seed reached physiological maturity, SSP’s had the longest fruit but fruit diameter and weight, seed number and seed weight per fruit was the lowest. However, SSP seed rendement was the highest. Flowers of lower branches developed faster, their fruits size, seed dry weight, and seed number was significantly higher than the upper branches. Nevertheles the seed viability and vigor was not different between lower and upper branches.</p><p>Keywords: fruit color, seed dry weight, seed viability, seed vigor</p>
