Diseases caused by Alternaria sp. are among the most common diseases of crops throughout the world. Alternaria sp. is a common component of the flora of wheat seed. Although isolation of Alternaria sp. from wheat (Triticum aestivum) seed has been reported in Argentina, development of the Alternaria blight in plants from infected seeds has not been demonstrated experimentally. Seed transmission ...

The genetic basis of seed germination and seedling vigor is largely unknown in Brassica species. We performed a study to evaluate the genetic basis of these important traits in a B. rapa doubled haploid population from a cross of a yellow-seeded oil-type yellow sarson and a black-seeded vegetable-type pak choi. We identified 26 QTL regions across all 10 linkage groups for traits related to seed...

in order to study the effect of density and time of urea foliar application on oil yield and essences percentage of black cumin (nigella sativa l.) a field experiment was conducted at research station of faculty of agriculture, azad university of birjand in 1387 growing season. three urea foliar application times [1-control 2-at 8-10 leaves stage 3-at 10% flowering 4-100% flowering ] and three ...

The present study investigated the neuroprotective effects of anthocyanins extracted from black soybean (cv. Cheongja 3, Glycine max (L.) MERR.) seed coat against oxygen-glucose deprivation (OGD) and glutamate-induced cell death in rat primary cortical neurons. Lactate dehydrogenase (LDH) release and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) reduction assays were employ...

We investigated a sample of 15 luminous high-redshift quasars (3.3 z 5.1) to measure the mass of their super-massive black holes (SMBH) and compare, for the first time, results based on C iv, Mg ii, and Hβ emission lines at high-redshifts. Assuming gravitationally bound orbits as dominant broad-line region gas motion, we determine black hole masses in the range of M bh ≃ 2 × 10 8 M ⊙ up to M bh...

Two-phased seed dispersal by primates and dung beetles is crucial for tropical rainforest regeneration. Two species of howler monkey exist in the tropical rainforests of southern Mexico: the mantled howler monkey (Alouatta palliata), and the black howler monkey (A. pigra). Differences between these species in foraging and traveling behavior, as well as associated dung beetle assemblages, may in...

cumin (cuminum cyminum l.) is one of the most important cultivable medicinal plants in iran and today, it is the second most popular spice in the world after black pepper. it is essential to know the relationships between yield and its components in cumin breeding programs. therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine the relatio...
