Consumption of greenhouse and field grown ‘Bragg’ soybean, Glycine max (L.) Merrill, foliage was determined for Pseudoplusia includens (Walker) larvae treated with varying dosages of Pseudoplusia nuclear polyhedrosis virus to produce different mortality levels. Uninfected P. includens larvae consumed an average of 158.3 and 78.7 cm2 of greenhouse and field grown soybean foliage, respectively. More than 84% of the total leaf area consumed was by the final two larval instars. The amount of foliage consumed by larvae infected as first (greenhouse and field) or second (greenhouse) instars was significantly reduced with increasing NPV mortality level. Foliage consumption by larvae infected as second (field) and third (greenhouse and field) instars at all dosage levels was significantly reduced when compared to the untreated checks, but differences in foliage consumption at the two lower mortality levels were not significant. Frass produced by infected and uninfected larvae was significantly correlated with the amount of greenhouse or field grown foliage consumed.

Larvae of the soybean looper (SBL), Pseudoplusia includens (Walker), were reared on three food types: soybean, Glycine max (L.) Merrill, genotypes ‘Kirby’ (insect susceptible) and GatIR 81-296 (insect resistant), and Florida beggarweed, (Desmodium tortuosum (Swartz) de Candolle. Larval development was longest on GatIR 81-296 (16.7 days) followed by beggarweed (15.5 days) and Kirby (14.1 days). Total consumption and relative consumption rate by ultimate (6th) instar SBL were significantly greatest on Kirby with no difference noted in consumption between GatIR 81-296 and beggarweed. However, approximate digestibility and efficiency of conversion of ingested food by ultimate instars were significantly greatest on beggarweed compared with the two soybean genotypes. Ultimate instar weight gain and growth rate were similar for larvae restricted to Kirby and beggarweed, while larvae restricted to GatIR 81-296 had significantly reduced weight gain and growth rate. Pupal weights of individuals reared on GatIR 81-296 also were significantly reduced compared with those in the Kirby and beggarweed treatments. SBL larvae consumed less beggarweed foliage (mg dry weight) than Kirby soybean, yet compensated to some extent by utilizing beggarweed foliage more efficiently. Beggarweed proved to be a better source of larval nutrition for SBL than the insect-resistant soybean genotype GatIR 81-296.

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.
