    An experiment on seed quality enhancement of common bean (Phaseolus vulgaris L.) var. S 9 (local) was conducted at the department of seed science and technology, OUAT, Bhubaneswar during 2013-14 by use of three biocontrol agents viz. Trichoderma viride, Trichoderma harzianum, Pseudomonas fluorescence. Seeds were bi-oprimed with the biocontrol agents at 40, 50 and 60 % concentration for 4,8,12 and 16 hours of soaking. Seeds were also hydro primed for 4,8,12 and 16 hours. Unprimed dry seed resulted in germination (69 %), shoot length (27.5 cm), root length (14 cm), seedling dry weight (1.71g), SVI-I (2859.2), SVI-II (118.0) and speed of germination (5.8) while hydro primed seeds resulted in germination (72%), shoot length (31.9 cm), root length (15 cm), seedling dry weight (1.80 g), SVI-1 (3375.9) SVI-II (129.8) and speed of germination (6.7). Trichoderma harzianum at 40% con-centration and for 4 hours of soaking resulted enhancement of above quality parameter like 13.0 % in germination, 21.1 % in shoot length, 20.7 % in root length, 31.6 % in seedling dry weight, 36 % in seedling vigour index-I, 48.1 % in seedling vigour index-II and 58.6 % in speed of germination over unprimed seeds. Bio priming with P. fluorescence ( at 40% concentration and for 4 hour) closely followed and at par with best treatment with 11.6 %, 18.2 %, 16.4 %, 30.4 %, 30.7 % and 56.9 % enhancement of above mentioned quality parameters, respectively

    We study the possibility of using W pair production and leptonic decay of one of the W's at the ILC with polarized beams as a probe of the Littlest Higgs Model. We consider cross-sections, polarization fractions of the W's, leptonic decay energy and angular distributions, and left-right polarization asymmetry as probes of the model. With parameter values allowed by present experimental constraints detectable effects on these observables at typical ILC energies of 500 GeV and 800 GeV will be present. Beam polarization is further found to enhance the sensitivity.Comment: 17 pages, plain latex, 6 figures, replaced with version accepted by JHEP, typographical errors removed, notation and references improved, new references added, explanation added in appendix regarding beam polarization dependenc

    Produktivitas publikasi ilmiah merupakan isu yang menarik untuk dibahas karena mencerminkan kontribusi dari lembaga penelitian atau individu peneliti dalam kegiatan penelitian. Program Pertukaran Mahasiswa Merdeka atau lebih sering disebutkan dengan PMM adalah salah satu bentuk kegiatan dari Pertukaran Pelajar dari Merdeka Belajar–Kampus Merdeka yang merupakan kebijakan dari Menteri Pendidikan dan Kebudayaan Republik Indonesia. Penelitian ini bertujuan untuk melihat produktivitas karya ilmiah mengenai program Pertukaran Mahasiswa Merdeka (PMM) dari angkatan 1 dan 2. Penelitian ini menggunakan pendekatan kualitatif deskriptif. Teknik pengumpulan data mengumpulkan publikasi artikel yang berhubungan dengan Pertukaran Mahasiswa Merdeka yang telah terbit di jurnal terakreditasi maupun tidak. Hasil penelitian menunjukkan bahwa terjadi peningkatan jumlah publikasi dari Pertukaran Mahasiswa Merdeka angkatan 1 ke angkatan 2, yaitu dari sebanyak 7 publikasi meningkat menjadi 97 publikas

    Metabolite Profiles of Sugarcane Culm Reveal the Relationship Among Metabolism and Axillary Bud Outgrowth in Genetically Related Sugarcane Commercial Cultivars

    Metabolic composition is known to exert influence on several important agronomic traits, and metabolomics, which represents the chemical composition in a cell, has long been recognized as a powerful tool for bridging phenotype–genotype interactions. In this work, sixteen truly representative sugarcane Brazilian varieties were selected to explore the metabolic networks in buds and culms, the tissues involved in the vegetative propagation of this species. Due to the fact that bud sprouting is a key trait determining crop establishment in the field, the sprouting potential among the genotypes was evaluated. The use of partial least square discriminant analysis indicated only mild differences on bud outgrowth potential under controlled environmental conditions. However, primary metabolite profiling provided information on the variability of metabolic features even under a narrow genetic background, typical for modern sugarcane cultivars. Metabolite–metabolite correlations within and between tissues revealed more complex patterns for culms in relation to buds, and enabled the recognition of key metabolites (e.g., sucrose, putrescine, glutamate, serine, and myo-inositol) affecting sprouting ability. Finally, those results were associated with the genetic background of each cultivar, showing that metabolites can be potentially used as indicators for the genetic background

    Probing strongly interacting W's at the ILC with polarized beams

    Full text link
    We study the possibility of fingerprinting a strongly interacting WW boson sector which is consistent with present day LHC searches at the ILC with longitudinal as well as transversely polarized electron and positron beams. We account for the final state interaction using a suitable Omn\`es formalism in terms of a plausible resonance description, and carry out thorough analyses of cross sections, asymmetries and angular distributions of the WsW's. We carry out a comparison with other extensions of the Standard Model, where heavy additional ZZ' bosons arise naturally. We also consider the effect of the strong final state interaction on a correlation that depends on (ϕϕ+)(\phi_--\phi_+), where the ϕ\phi_\mp are the azimuthal angles of decay leptons, and find that it is a useful discriminant.Comment: 25 pages latex using JHEP style files, 14 figures; v2 is a slightly expanded version of v1, reference added, discussions improved, some figures have been changed; corresponds to version accepted for publication in JHE
