to evaluate interaction of salinity stress and nitrogen use methods on yield and yield components, in experiment was conducted in split plot in randomized complete block with 3 replications. treatments included: salinity of irrigation water levels 1.5, 4.4 and 7.9 ds/m as main plots, and nitrogen treatments 1. using n fertilizer at 3 stage in soil, 2. using two third n fertilizer in soil at pla...

The article presents the results of studying influence quantitative traits on barley plant performance. Thirty typical plants were selected for each 28 genotypes spring two-row cultivars and their height, productive tillering capacity, spike length, number weight kernels from main spike, 1000-kernel weight, performance measured. As a result, we found significant positive correlations between ca...

terminal heat stress is the most widespread heat stress in the world. in order to evaluate the effect of heat stress on yield, yield component, and mopho-phenological traits of barley, 10 barley genotypes including the 2-row genotypes: mahour, khoram, nimrooz, abidar and 6-row genotypes: yousef, rihan 03, izeh, zahak, nosrat, jonoub were tested under normal (optimum sowing date) and heat stress...

Exploratory tools that are sensitive to arbitrary statistical variations in spike train observations open up the possibility of novel neuroscientific discoveries. Developing such tools, however, is difficult due to the lack of Euclidean structure of the spike train space, and an experimenter usually prefers simpler tools that capture only limited statistical features of the spike train, such as...

Spring wheat yields across the Canadian prairies are rising, however, a yield gap remains between average and potential which can be explored further under Prairie conditions. The high rates of nitrogen (N) fertilizer required for current high-yielding cultivars may increase lodging risk adding to this gap. objectives study were determine influence intensive management through N fertilization p...

continual heat stress affects approximately 7 million hectares of wheat in developing countries, while terminal heat stress is a problem in 40% of temperate environments, which cover 36 million hectares throughout the world. heat tolerance is a quantitative and complex trait that doesn’t have much success in direct selection. for this purpose, however, a thorough understanding of physiological ...

To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...

This work presents two kernels which can be applied to sets of spike times. This allows the use of state-of-the-art classification techniques to spike trains. The presented kernels are closely related to several recent and often used spike train metrics. One of the main advantages is that it does not require the spike trains to be binned. A high temporal resolution is thus preserved which is ne...
