Maturity Groups

The effect of temperature during growth on the photosynthetic characteristics of soybean (Glycine max [L.] Merrill) was studied using cultivars from Maturity Group 00 (Altona, Fiskeby V, Flambeau, Maple Presto, McCall) and MG VIII (Hampton 266–A, Hardee, Johnston, Kirby). In one experiment plants were grown with 950 μmol m−2s−1 photosynthetic photon flux density (PPFD) at 18, 20, 25 and 30 °C. When grown at 20 °C, MG 00 cultivars averaged significantly higher rates of photosynthesis measured at 25 °C and saturating PPFD than did MG VIII cultivars. Cultivars were also grown with a PPFD of 540 μmol m−1 at 17.5, 20.0, 22.5 and 25.0 °C. Maturity Group 00 cultivars averaged higher photosynthetic rates than MG VIII cultivars at the 20.0 and 22.5 °C growth temperatures. The other growth environments produced no significant differences between maturity groups. Photosynthetic rates differed between cultivars, but not maturity groups, after exposure to a single night with a gradual temperature decline to 8 °C. Photosynthetic rates recovered in 28 h. Two cultivars, Altona and Johnston, were grown outdoors at three times during one growing season at Beltsville, and their maximum photosynthetic rates changed depending on the temperatures during leaf development, in agreement with the data from the controlled environment studies.Key words: Soybean, Glycine max [L.] Merrill, photosynthesis, temperature, acclimation

Accumulation and distribution of manganese in soybeans (Glycine max [L.] Merr. cvv. Lee and Bragg) grown over a range of manganese concentrations from 0 to 275 8m in solution culture were studied at four day-night temperatures ranging from 20-15�C to 33-28�C in growth cabinets. High levels of solution manganese (275 8m ) produced symptoms of manganese toxicity and reduced yields of both varieties with the symptoms and yield reductions being more severe on Bragg than Lee. Increasing the day-night temperatures from 20-15�C to 33-28�C increased the ability of both cultivars to tolerate high concentrations of manganese in solution but there was no indication of any effect of temperature on the differential tolerance of the two cultivars. At high managanese concentrations in solution, high temperatures increased the rate of absorption by roots and total plant uptake of manganese, but there was no effect on the concentration of manganese in the plant tops. Total leaf concentration increased markedly while stem concentration were reduced at high temperatures. Young leaves contained lower concentrations of manganese than older leaves at all temperatures. While the concentration of manganese in the youngest expanding leaf decreased slightly as temperatures were raised from 20-15�C to 28-25�C, there was no significant difference in concentrations at 20-15�C and 33-28�C. These results suggest that the increased tolerance of soybeans to high manganese supply was not due to growth dilution in young tissues.

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.
