<em>Ketersediaan dan pemanfaatan dari sayuran indigenous masih sangat terbatas. Pengujian mutu benih menjadi langkah dasar yang penting untuk memenuhi kebutuhan produksi dan konsumsi dari sayuran indigenous. Penelitian ini bertujuan: (1) pengembangan metode uji daya berkecambah benih kecipir pada aspek penentuan pengamatan hitungan pertama dan kedua; (2) pemilihan substrat alternatif perkecambahan. Penelitian dilaksanakan di Laboratorium Pengujian Mutu Benih dan Penyimpanan Benih IPB selama lima bulan. Penelitian dibagi ke dalam dua percobaan, percobaan pertama yaitu penentuan hitungan pertama dan kedua, percobaan kedua yaitu optimalisasi substrat perkecambahan. Hasil penelitian menunjukkan bahwa penentuan hitungan dalam pengamatan uji daya berkecambah benih kecipir menggunakan alat pengecambah tipe eco-germinator dilakukan pada hari ke-6 untuk hitungan pertama dan hari ke-8 untuk hitungan kedua. Kertas CD dapat digunakan sebagai substrat kertas alternatif apabila pengujian benih menggunakan metode UKDdp. Substrat pasir kontrol dengan metode in sand merupakan substrat terbaik apabila pengujian benih dilakukan tanpa menggunakan substrat kertas.</em>

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.
