background & aim: investigating the possibility of using medicinal plant’s seeds substitute for agar gel in plant tissue culture and determining the optimal practical conditions of them is the aim of this study. experimental: in order to study the new gelling agents for using in plant tissue culture, we designed a tow part experiment by means of the seeds of medicinal plants such as linum u...

wheat stem reserves can be an important contributor to grain particularly under decrease in the source strength through defoliation. the aim of this research was to study ability remobilization as important contribution on yield stability under drought conditions and to investigate their intrinsic compensatory mechanism in the wheat cultivars with different degrees of resource limitations under...

salinity stress results to decreasing leaf area index (lai) and light absorption in plant leading in yield decrease. in order to study effect of salinity and iron sulphate on lai, absorbed light percentage and yield of sunflower (euroflor cultivar), an experiment was carried out as split plot based on complete randomized block design with four replications in the research field of university of...

an experiment was carried out in 2008-2009 to study the correlation between the reaction to potassium chlorate and pathogenicity on some iranian isolates of macrophomina phaseolina, the causal agent of soybean charcoal rot. from among a total of 48 collected isolates from the major soybean cultivation areas of golestan, mazandaran, ardabil, and lorestan provinces, twenty four isolates were sele...

the application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. in this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. the five treatments were control (withoutamendment), municipal solid waste compost (mc), vermicompost...
