Delayed Flowering

The inheritance of flowering time was studied in the short-day soybean, Glycine max (L.) Merr., under long-day conditions in the greenhouse using natural day length extended to 20 hours with cool-white fluorescent light. A single, major gene with two alleles was found to control the flowering response. The dominant allele which gave a fluorescent-sensitive response of delayed flowering also resulted in later field maturity whereas the recessive allele which gave an insensitive response resulted in earlier maturity. The maturity symbols E3 and e3 are proposed for these alleles. Isolines have been developed.

Aim. The aim of the work was to study the effects of genes controlling the plant development rates on the speed of transition to generative development and formation of individual productivity of isogenic lines of wheat (Triticum aestivum L.) and soybean plants (Glycine max (L.) Merr.) according to the genes. Methods. The experiments were carried out in the field conditions. The periods of sprouting and earing (PSE) of wheat, the periods of sprouting and flowering (PSF) and ripening (PSR) of soybean isogenic lines and the elements of the structure of individual productivity were determined. Results. It was shown that under conditions of a natural long day (16 hours), wheat plants with genotypes VRN-A1a, VRN-D1a, PPD-A1a and PPD-D1a more rapidly passed to the earing. In soybean isogenic lines, the presence of dominant alleles of the E-series genes increased the duration of phases of PSF and PSR. The maximum indicators of productivity elements were characterized by isogenic lines, developed at a faster rate. Conclusions. The genes controlling the development rates of soft wheat and soybean crops, defining the timing of the transition to generative development, determine their productivity.

The aim of the research. To reveal the patterns of genetic control of assimilation processes in isogenic by E-genes lines of soybean conditions of different photoperiod duration. Materials and methods. The plant material – 5 isolines of soybean (Glycine max (L.) Merr.) Cv. Clark: short-day (SD) lines (genotypes E1E2E3, E1e2e3) and neutral-day (ND) lines (genotypes e1E2e3, e1e2E3, e1e2e3). From the third true leaf stage, one part of the plants was grown on a natural day (16 hours), and the other was exposed to a short day (9 hours). On the day of the start of the experiment, after 7 and 14 days, the dry weight of leaves and stems, the number and area of leaves were measured, based on which assimilation indices were calculated – RGR, NAR, LAR, SLA, LWR. Results. During the studied ontogenetic period (two weeks) in all isolines, regardless of the genotype by E-genes and the duration of the photoperiod, the assimilation processes increased. The RGR and NAR under the short day decreased in the first week and then increased in the second week of the experiment. The degree of change in the indices varied depending on the isoline genotype by E-genes. The LAR and LWR were lower under the short day in SD lines. These indices were the same in the ND lines under short and long day. Under the short photoperiod the SLA in SD lines was higher, and in ND lines it was practically the same for both photoperiods. Conclusions. The assimilation processes in the studied isogenic lines during the experience (two weeks) increase, but less intensively under short-day conditions. The studied lines, differed in the nature and intensity of assimilation processes, depending on the genotype by E-genes. Assimilation processes in the studied soybean lines are probably determined by the interaction of E-genes and the duration of the photoperiod, which is one of the important conditions for the adaptation of soybean to the environmental factors

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.
