In order to explore the possibility of enhancing wheat productivity with limited inputs, an experiment entitled “Effect of seed soaking in nitrogen, phosphorus and herbicides solutions on yield and other characteristics of wheat” was conducted at the Agriculture Research Farm of NWFP Agricultural University Peshawar during winter2002-03. Seeds were soaked in pure water, 0.1% and 0.5% urea solut...

Genetic differences among major types of wheat are well characterized; however, little is known about how these distinctions affect the small molecule profile of the wheat seed. Ethanol/water (65% v/v) extracts of seed from 45 wheat lines representing 3 genetically distinct classes, tetraploid durum (Triticum turgidum subspecies durum) (DW) and hexaploid hard and soft bread wheat (T. aestivum s...

mechanical damage due to harvesting, handling, and other processes is an important factor that affects the seeds quality. seed damage results in lower grain value and more storability problem and reduces seed germination and seedling vigor and subsequent yield of crops. tests were conducted to determine the percentage of physical damage (ppd) and percentage of loss in germination (plg) of wheat...

This is the first-ever study conducted to standardize the maturity stage of olive fruit for development of olive murabba. Olive fruit was harvested at three different maturity stages including lemon green, semi-ripened and fully ripened stages for postharvest processing. Most prominent quality parameters of the product were studied for all maturity stages. Olive productprepared from semi-ripene...

To evaluate the effect of residue of sulfonylurea herbicides and  wheat residues on the growth and yield of sunflower, a split factorial experiment was conducted based on a randomized complete block design (RCBD) with four replications at the College of Agriculture, Shiraz University, Shiraz, Iran. The treatments included with and without wheat residues from the tested farm as the main plots, a...

The emergence of new sequencing technologies has provided fast and cost-efficient strategies for high-resolution mapping of complex genomes. Although these approaches hold great promise to accelerate genome analysis, their application in studying genetic variation in wheat has been hindered by the complexity of its polyploid genome. Here, we applied the next-generation sequencing of a wheat dou...

Soil-dwelling insects are severe pests in many agroecosystems. These pests have cryptic life cycles, making sampling difficult and damage hard to anticipate. The management of soil insects is therefore often based on preventative insecticides applied at planting or cultural practices. Wireworms, the subterranean larvae of click beetles (Coleoptera: Elateridae), have re-emerged as problematic pe...

The development of F1 hybrid varieties of wheat is reviewed under four main headings: male sterility, hybrid seed production, the performance of hybrids and commercial aspects. The three systems for male sterility used in wheat (cytoplasmic male sterility, nuciear male sterility and chemical hybridizing agents) are described and it is noted that no system is without problems or has a clear adva...

Thioredoxins h are ubiquitous proteins reduced by NADPH- thioredoxin reductase (NTR). They are able to reduce disulphides in target proteins. In monocots, thioredoxins h accumulate at high level in seeds and show a predominant localization in the nucleus of seed cells. These results suggest that the NTR-thioredoxin h system probably plays an important role in seed physiology. To date, the study...

times that needed to denature egg albumin, using the estimate given by Mirskyl2 or fifty times the energy needed for the inactivation of certain ionic forms of pepsin according to Steinhardt's determinations."3 The denaturation of egg albumin by ultra-violet light is a first order reaction,'4 i.e., the survival curve is a straight line similar to that obtained for chromosome abnormalities. It s...
