Selection Of

The leghemoglobins from a genetically diverse selection of 69 cultivated soybean (Glycine max (L.) Merr.) cultivars and plant introductions and 18 wild soybean (Glycine soja Sieb. & Zucc.) plant introductions all consist of the same set of major leghemoglobins (a, c1, c2, c3), as determined by analytical isoelectric focusing. The conservation of both leghemoglobin heterogeneity and also all four major leghemoglobin structures provides strong circumstantial evidence that leghemoglobin heterogeneity is functional. Glycine max and G. soja produced the same leghemoglobins in the presence of Bradyrhizobium japonicum (Kirchner) Jordan and in the presence of fast-growing Rhizobium japonicum.

Abstract Although soybean [Glycine max (L.) Merrill] grows as an inbreeding, generally homozygous, plant, the germplasm of the species contains large amounts of genetic variation. Analysis of soybean DNA has indicated that variation of RFLP (restriction fragment length polymorphism) markers within the species usually entails only two alleles at any one locus and that mixtures of such dimorphic loci account for virtually all of the restriction fragment variation seen in soybean (G. max), and in its ancestors, G. soja and G. gracilis. We report here that tissue cultures prepared from root tissue of individual soybean plants develop RFLP allelic differences at various loci. However, these newly generated alleles are almost always the same as ones previously found and characterized in other varieties of cultivated soybean (cultivars). This repeated generation of particular alleles suggests that much of the genetic variation seen in soybean could be the consequence of specific, relatively frequently employed, recombinational events. Such a mechanism would allow inbred cultivars to generate genetic variation (in the form of alternative alleles) in a controlled manner, perhaps in response to stress.

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.
