Among the crops, cereals have been special important and triticale is the most successful man made cereal. In present research, water deficit stress effects on 19 triticale genotypes (X Triticosecale wittmack) and two wheat cultivars (Triticum aestivum), Shiraz (sensitive to water deficit stress) and Kavir (tolerant to water deficit stress) were tested. Therefore, two separate field experiments...

In situ and light-saturated net photosynthetic rates per unit leaf area were greater in cotton (Gossypium hirsutum L.) plants grown in pots in the field than in similar plants from a phytotron growth chamber. Light-saturated stomatal resistances did not differ in leaves of similar age and exposure on field and chamber plants; lower photosynthetic rates in chamber leaves were associated with gre...

Two kinds of spikes, a single-spike unit and burst unit, were obtained by a glass suction electrode recording from neurons in Auerbach's plexus of the guinea pig ileum. Both spikes were inhibited by tetrodotoxin but not by Mn2+. Frequency of the single-spike unit was increased by nicotine and high concentrations of acetyl choline. The single-spike unit induced by nicotine was inhibit...

Improving the drought tolerance of barley varieties through the integrated efforts of plant biotechnology and conventional breeding is an important objective in barley breeding. One hundred and fifty eight doubled haploid lines of barley were mapped with 50 SSR and 93 AFLP markers. Agronomic traits such as early growth vigor, plant height, peduncle length, extrude of spike from flag leaf, spike...

Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...

In order to evaluate and grouping wheat genotypes based on grain yield and important agronomic traits under drought stress, a field experiment was conducted with 43 wheat genotypes using a Randomized Complete Block design in three replication at Azad University, khorramabad, Iran in 2012-2013 cropping season. Evaluated traits were: day to maturity, day to pollination, grain filling rate, grain ...

Barleys one of the important four major crops in the world after wheat, corn and rice. About 2.16 million hectare of arable land was cultivated by barely in 2011-2012. In order to investigate heritability and gene action was used barely half-diallel of 7 × 7 in some barley-related yield traits. For this purpose were used in 6 barley genotypes with Sahra variety (the native desert). Tests carrie...

The nature of the neural codes for pitch and loudness, two basic auditory attributes, has been a key question in neuroscience for over century. A currently widespread view is that sound intensity (subjectively, loudness) is encoded in spike rates, whereas sound frequency (subjectively, pitch) is encoded in precise spike timing. Here, using information-theoretic analyses, we show that the spike ...
