Africanized Honeybees

This research was carried out to evaluate the pollination by Africanized honeybees Apis mellifera, the floral biology and to observe the hoarding behavior in the soybean flowers (Glycine max Merril), var. BRS-133. The treatments were constituted of demarcated areas for free visitation of insects, covered areas by cages with a honeybee colony (A. mellifera) and also covered areas by cage without insects visitation. All areas had 24 m² (4m x 6m). The soybean flowers stayed open for a larger time (82.82 ± 3.48 hours) in covered area without honeybees. The stigma of the flowers was also more receptive (P=0.0021) in covered area without honeybees (87.3 ± 33.0%) and at 10:42 o'clock was the schedule of greater receptivity. The pollen stayed viable in all treatments, the average was 99.60 ± 0.02%, which did not present differences among treatments. The percentage of abortion of the flowers was 82.91% in covered area without honeybees, this result was superior (P=0.0002) to the 52.66% and 53.95% of the treatments uncovered and covered with honeybees, respectively. Honeybees were responsible for 87.7% of the pollination accomplished by the insects. The medium amounts of total sugar and glucose measured in the nectar of the flowers were, 14.33 ± 0.96 mg/flower and 3.61 ± 0.36 mg/ flower, respectively, not showing differences (P<0.05) among the treatments. The total solids, measured through the manual refratometer were 21.33 ± 0.22% in uncovered area and 22.33 ± 0.38% in covered with honeybees and differed to each other (P=0.0001). The honeybees were the most frequent insect (95.18%). Other observed insects were the Lepidoptera with 3.51% and other bees with 1.32%, in uncovered area. Honeybees visited 2.24 flowers on average in uncovered area and 1.58 in covered with honeybees and presented behavior for nectar hoarding and hoarding nectar/pollen in this period. In uncovered area the time of nectar hoarding was 2.55 ± 0.07 seconds, this time was smaller (P=0.0039) than 2.87 ± 0.08 seconds observed in covered area with honeybees. The behavior for the hoarding type observed in honeybees foraging the soybean flowers, through the content of its honey stomach and pollen loads of its pollen basket showed that the nectar forager did not show a pattern for the nectar collection, but for the pollen collection the schedule of pollen peak of the forager was at 11:36 o'clock. The soybean flowers showed alteration in floral biology when exposed to honeybees.

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.

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>
