hybrid rice varieties are potentially higher yielding than the best inbred varieties and perform better under adverse conditions of drought and salinity. one of the major impediments for seed production of hybrid rice is incomplete panicle exsertion in the cytoplasmic male sterile lines. the unexserted spikelets which are left inside the flag leaf sheath remain unfertile. this research was focu...

In In order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (RCBD) with 4 replications in Saat-Loui agricultural station of West Azerbaijan province. In this research, the first factor (A) contained two levels 20 and 40 cm inte...

We consider a totally nonsymplectic (TNS) Anosov action of Zk which is either uniformly quasiconformal or pinched on each coarse Lyapunov distribution. We show that such an action on a torus is C∞–conjugate to an action by affine automorphisms. We also obtain similar global rigidity results for actions on an arbitrary compact manifold assuming that the coarse Lyapunov foliations are topological...

To study the performance of soybean (Glycine max L.) cultivars in varying weeding regimes, a field experiment was conducted in 2010. The experiment was split plot in a randomized complete block design with 3 replicates. The four cultivars and two lines of soybean including: Sahar, Hill, Sari, Telar, 032 and 033 in main plot and weeding regime consist of no weeding (control), one weeding (35 day...

The root-lesion nematodes Pratylenchus neglectus and P. thornei are economically damaging pathogens of wheat in the Pacific Northwest (PNW). Growing resistant and tolerant varieties is the best approach to minimize yield loss. All PNW wheat varieties were found to be susceptible. Crosses were made between the PNW-adapted varieties (Alpowa Louise, Otis) and the Australian wheat GS50a with resist...

Bread wheat landraces are considered among important gene sources for quality breeding programs. This study aims to compare thousand kernel weight crude protein ratio, dry gluten grain hardness and zeleny sedimentation results of 20 bread lines selected from 5 registered cultivars in order determine future candidates Field experiments were conducted the consequent 2012-2013 2013-2014 growing se...

Many polyphenolics contained in mango have shown anticancer activity. The objective of this study was to compare the anticancer properties of polyphenolic extracts from several mango varieties (Francis, Kent, Ataulfo, Tommy Atkins, and Haden) in cancer cell lines, including Molt-4 leukemia, A-549 lung, MDA-MB-231 breast, LnCap prostate, and SW-480 colon cancer cells and the noncancer colon cell...

two separate experiments were carried out with the aim of investigating the effect of vermicompost and its aqueous extracts on traits related to germination and growth of tomato varieties, (mobil and superorbina). in the first experiment, 0.5, 1, 1.5, 2, 2.5, 5, 7.5, 10 and 100% extracts of vermicompost (v - v) along with control (distilled water) were studied on germination of two varieties of...

ABSTRACT- In order to produce transgenic rice lines lacking selectable marker gene, biolistic co-transformation technique using gold nanoparticles was adopted. In the first step, the efficiency of different sizes of gold particles was evaluated. The results showed that the efficiency of the nanoparticles in the transformation was comparable to that of the micro particles. Subsequently, two sepa...
