A large proportion of mutants with altered pigment features have been obtained via exposure to heavy-ion beams, a technique that is efficient for trait improvement in the breeding of plants and algae. However, little is known about the underlying mechanisms by which the photosynthetic pigments are altered by heavy-ion irradiation. In our study, the photosynthetic characteristics of progenies fr...
This study was done to investigate and compare fruit yield, yield components, morphological traits and fruit quality of greenhouse tomato genotypes in order to use them as selection criteria. Progenies of 49 crosses of greenhouse tomato together with their 13 parents were evaluated using Randomized Complete Block Design with three replications. The highest amount of fruit yield was observed in ...
based on the importance of drops' behavior in liquid-liquid extraction, the maximum sauter mean drop diameter has been investigated and correlated in a counter-current spray extraction column with two chemical systems. spargers were set of nozzles in all experiments. studying the effects of several parameters on drops size, some correlations were estimated by the last available version of softw...

چـکـیده مقدمه: در طول دو دهه ی اخیر بخش قابل توجهی از تمرکز سازمان ها بر روش های مدیریت هزینه ها (cost management)، و رشد درآمدها (revenue growth) معطوف گشته است. توجه صرف به مدیریت هزینه یا رشد درآمد به مفهوم از دست دادن فرصت بهره مندی از دیگری است. به این ترتیب چیزی که لازم به نظر می رسد ایجاد توازن و هماهنگی بین این دو می باشد؛ اما چگونه این توازن اتفاق می افتد؟ ارزیـابی ارزش هر مشتری، تخ...
in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...
Abstract Slavonian oak ( Quercus robur subsp. slavonica (Gáyer) Mátyás) is currently gaining interest in forestry due to forest restructuring Germany caused by climate change. oaks originating from Croatia have been introduced into mainly the Münsterland region of North Rhine-Westphalia since second half nineteenth century. They are characterized their late bud burst, long clear bole, stem stra...
