This study aims to quantify the phosphorus (P) concentration in the commercially adapted ten corn hybrids in South Dakota and to determine if selection can be carried out for these traits to develop useful inbred lines; to determine the effect of planting densities on P concentrations and dry matter (DM) yields. Results showed that hybrid were significantly differences for percent phosphorus. H...

Precise regulation of synaptic vesicle (SV) release at the calyx of Held is critical for auditory processing. At the prehearing calyx of Held, synchronous and asynchronous release is mediated by fast and slow releasing SVs within the readily releasable pool (RRP). However, the posthearing calyx has dramatically different release properties. Whether developmental alterations in RRP properties co...

The sensitivity of posttetanic potentiation (PTP) to high-frequency stimulation (HFS) steeply decays during the first 2 postnatal weeks. We investigated the underlying mechanisms for the developmental change of PTP induced by HFS (100 Hz, 2 s) at postnatal days 4-6 and 9-11 at the rat calyx of Held synapse. Low-concentration tetraphenylphosphonium (2 μM), an inhibitor of mitochondrial Na(+)/Ca(...

in order to study the yield and forage quality of intercropping barley (hordeum vulgare) and mustard (sinapis alba) in different planting dates, a factorial experiment based on randomized completely block design with three replications was carried out at farm research station, gonbad -e- qabus university. factors were included as three planting dates (15 november, 6 and 20 december 2006) and fo...

for comparison the growth characteristics and quantitative and qualitative yield of two summer savory species (such as satureja khuzestanica and s. rechingeri) in response to rainfed and irrigated conditions, an experiment was carried out on the basis of split-plot design in completely randomized block design with three replicates in north of khuzestan during growing season of 2012-2013. irriga...

12 Developmental changes in Ca 2+ clearance and short-term plasticity 13 14 15 Abstract 26 27 The sensitivity of post-tetanic potentiation (PTP) to high frequency stimulation (HFS) steeply decays during 28 the first two postnatal weeks. We investigated the underlying mechanisms for the developmental change of PTP 29 induced by HFS (100 Hz, 2 sec) at postnatal days 4-6 and 9-11 at the rat calyx ...

We made flattened neuroepithelial preparations of horizontal and vertical (anterior and posterior) cristae from mouse, rat, gerbil, guinea pig, chinchilla, and tree squirrel. Calretinin immunohistochemistry was used to label the calyx class of afferents. Because these afferents are restricted to the central zone of the crista, their distribution allowed us to delineate this zone. In addition to...

Endoparasitic wasps are able to develop inside permissive host insects due to their ability to overcome or evade the host's immune system. In the present study, we provide experimental evidence that ovarian calyx fluid of the ichneumonid endoparasitoid Venturia canescens has the potential to alter host haemocyte spreading and inhibit host haemolymph melanisation due to the presence of a putativ...

Field experiment was conducted at KPK Agricultural University, Peshawar, Pakistan to find out the effect of planting methods on the yield and yield components of maize varieties. Analysis of the data revealed that planting methods had a significant effect on days to tasseling, days to silking, plant height, number of plants ha at harvest, thousand grain weight, grain yield, biological yield, fr...

To survey the effects of chemical and biological phosphorus on the yield and essential oil of Satureja hortensis L. as an important medicinal plant, factorial experiment was conducted based on randomized complete block design with three replicates at Research Station of Faculty of Agriculture, Urmia University in 2011. The treatments were chemical phosphorus fertilizer with four levels (0, 50, ...
