Primary trisomics are ideal cytogenetic tools for associating genes and linkage groups to known chromosomes and testing their independence. In the cultivated soybean, only 8 of the possible 20 primary simple trisomics are known. In this report cytological evidence for the identification of five more new primary simple trisomics, corresponding to chromosomes 6, 8, 12, 16, and 19, is presented for the first time. The precise identification was based on trivalent configuration of chromosomes at the pachynema stage of meiosis, where the chromosomes were identified by their characteristic total length, arm ratio, and distribution of heterochromatin and euchromatin. Cytological observation of chromosome pairing in the 2n = 42 chromosome F1 plants, obtained from eight crosses between known primary trisomics, also supported the identification of primary trisomics in soybean based on pachytene chromosome analysis. Together with the eight primary trisomics identified previously, 13 of the possible 20 primary simple trisomics have been successfully identified, which accounts for about 76% of the total nuclear euchromatin in soybean.Key words: Glycine max, soybean, trisomic, pachytene chromosome, chromosome pairing.

Chromosome Stickiness

Chromosome analysis of the root tips of Glycine max (L.) Merrill variety T219 revealed several aberrations. Chromosome stickiness, reductional groupings and multiple spindles (as well as multipolar spindles) were observed. In our previous work, we had observed the expression of homozygous genotypes on the heterozygous background in the form of small spots on the leaves of this variety. This paper tends to correlate the two findings. The appearance of some of the spots on the leaves is attributed to the loss of one or more chromosomes, besides somatic crossing-over.

Glycine Max L

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.

Penelitian tentang pengaruh pemberian Pupuk organik cair (POC) asal limbah tumbuhan terhadap serapan hara N dan P serta produksi tanaman kedelai (Glycine max (L) Merrill) di lahan gambut telah dilaksanakan di kampus II Unisi Fakultas Pertanian Jl. Lintas Propinsi Parit 01, Desa Pulau Palas, Kecamatan Tembilahan Hulu, Kabupaten Indragiri Hilir Propinsi Riau. Dimulai dari bulan Agustus sampai bulan Oktober 2013. Tujuan dari penelitian ini untuk mendapatkan POC asal limbah tumbuhan yang terbaik untuk serapan hara N dan P serta produksi tanaman kedelai di lahan gambut. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktor tunggal dengan 7 perlakuan dan 4 ulangan, 2 tanaman dijadikan sampel. Perlakuan dosis POC limbah tanaman pisang dan POC limbah sayur kol yang diberikan yaitu 0 L/Ha, 200 L/Ha, 400 L/Ha dan 600 L/Ha. Parameter pengamatan yaitu : serapan hara N dan P pada fase awal generatif, tinggi tanaman, jumlah bintil akar, polong hampa, produksi perplot, berat 100 biji dan brangkasan kering. Data pengamatan dianalisis dengan sidik ragam (ANOVA) dan dilanjutkan dengan Uji Lanjut Tukey HSD pada taraf 5%. Berdasarkan penelitian yang telah dilaksanakan dapat disimpulkan bahwa pemberian POC asal limbah tumbuhan tidak berpengaruh nyata terhadap serapan hara N dan P, tinggi tanaman, jumlah bintil akar, polong hampa, brangkasan kering tetapi berpengaruh nyata terhadap produksi perplot dan berat 100 biji.

Induced Changes

Heavy metals are one of the most important pollutants released to the aquatic environment by the various industrial activities. The use of these wastewater for irrigation results accumulation of heavy metals in soil and plants. So, the present investigation deals with the various concentrations (0, 5, 10, 25, 50, 100, 200 and 300 mg/l) of copper and zinc on germination studies of soybean. The different concentrations of copper and zinc were used for germination studies. The seedlings were allowed to grow upto seven days. The studied morphological traits increased at 5 mg/l concentration and these parameters are gradually decreased with the increase of copper and zinc concentrations.

<p><em>Penelitian ini bertujuan untuk mengetahui pengaruh tiga jenis kemasan yaitu kemasan hermetik, jeriken plastik dan karung </em><em>beralas </em><em>plastik terhadap mutu fisik maupun fisiologis benih kedelai (Glycine max (L.) Merrill) varietas Anjasmoro selama penyimpanan. Penelitian dilaksanakan di Laboratorium Ilmu dan Teknologi Benih, Departemen Agronomi dan Hortikultura, Fakultas Pertanian, Institut Pertanian Bogor pada bulan </em><em>Januari</em><em> sampai </em><em>Juli</em><em> 2016. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dengan tiga ulangan. Faktor perlakuan yang digunakan adalah jenis kemasan (P) yang terdiri atas tiga taraf yaitu kemasan hermetik (P1), jeriken plastik (P2), dan karung </em><em>beralas </em><em>plastik (P3). Penyimpanan dilakukan selama 6 bulan dan diamati setiap bulan terhadap variabel kadar air, daya berkecambah, indeks vigor, kecepatan tumbuh, keserempakan tumbuh dan bobot kering kecambah normal. Hasil penelitian menunjukkan bahwa perlakuan jenis kemasan tidak memberikan pengaruh yang nyata terhadap mutu fisik maupun fisiologis benih kedelai varietas Anjasmoro selama penyimpanan. Perlakuan jenis kemasan dapat mempertahankan viabilitas dan vigor benih kedelai hingga bulan ke-2 penyimpanan. Hasil tersebut menunjukan bahwa benih kedelai dapat disimpan selama 4 bulan setelah panen.</em></p>
