Wheat plants (Triticum aestivum L., cv. Warigal) were subjected to 20 d of water deficit during the period of endosperm cell division. Drought accentuated the differences in final grain weight between spikelets and between grains within spikelets. The distal grains of top spikelets were most affected by drought. The maximum number of endosperm cells was, respectively, 30 and 40 per cent lower i...

OBJECTIVE To examine the relation between dietary composition and weight change among children. We tested several hypotheses considering intake of nutrients (total fat and fiber) and predefined food groups (breads and grains, "fat foods," fruits, and vegetables) used in the North Dakota Special Supplemental Nutrition Program for Women, Infants, and Children (WIC Program). DESIGN Prospective s...

Plant growth regulators (PGRs) are used to prevent reduction in wheat grain yield under limited moisture conditions. The effect of 3 PGRs including cycocel, salicylic acid and brassinoestroeid on yield and yield components of  four wheat cultivars (Chamran, Shiroudi, Pishtaz and Sirvan) under well watered and water stress (withheld irrigation after flowering) was examined. The experiment was ca...

We study the motion of dust grains into the Intergalactic Medium (IGM) around redshift z = 3, to test the hypothesis that grains can efficiently pollute the gas with metals through sputtering. We use the results available in the literature for radiation-driven dust ejection from galaxies as initial conditions, and follow the motion onward. Via this mechanism, grains are ejected into the IGM wit...

Development of superior crop varieties is the prime objectives of all plant breeding programs. To determine genetic variability, heritability and genetic advance, 24 elite bread wheat lines were planted in randomized complete block design with three replications at the University of Agriculture, Peshawar under rainfed conditions. Data were recorded on days to heading, days to maturity, plant he...

Plastic film mulching (PM) is widely utilized for maize production in China. However, the effect of PM on the grain yield of crops has not been established, and the biochemical mechanism underlying the increase or decrease in grain yield under PM is not yet understood. Grain filling markedly affects the grain yield. The objective of this study was to investigate the effects of PM on maize grain...

In recent years, studies have been carried on the selection and breeding of melon to reduce its production cost. The F1 seeds this species are usually created by parental lines. Notably, lines separated from each other secure materials. However, there no establishing suitable conditions for storing pollen grains Japanese Cucumis melo L. study, C. were dried at 38 oC temperature, 1.5 hours, whic...

The insecticidal properties and mechanisms of high-voltage air-based atmospheric cold plasma using a contained dielectric barrier discharge reactor were investigated against Tribolium castaneum as an important bio-contaminant in stored grains spoilage. mortality 95.0%–100% for preadult stages can be achieved within seconds treatment, but longer exposure (5 min) is required to kill adult insects...

In order to investigate the effects of salinity stress and three nitrogen fertilizers on some traits of psyllium (Plantago ovata) plants, a factorial experiment, as completely randomized design with three replications, was carried out at University of Zabol, in 2010. Salinity at three levels (0, 100 and 200 mM sodium chloride) was the main plot and three forms of nitrogen source (nitrate from c...
