Two different propagation procedures including aeroponics and soil systems were compared for the minitubers production in potato. The minitubers were evaluated for several quality characters. The plant materials were from three cultivars, Agria, Marfona and Savalan. The plantlets were grown in aeroponics and soil production systems at a plant density of 100 plants per m-2 and stem length, root ...

Response of Iranian Rice Recombinant Inbred Lines (Oryza sativa L.) to Salt Stress in Seedling Stage
Study of the morphological genetic diversity of 114 lines, which have been derived from the crosses between Tarom Mahalli and Khazar cultivars, has been performed at seedling stage as completely randomized design at the normal condition and salinity stress of 8 dS.m-1 in a hydroponic system. Significant differences were detected between genotypes for all traits. Mean of comparison demonstrated ...
abstract in order to evaluate the effects of rice conventional herbicides on rotational second crops (lettuce, cress, clover, canola and radish), soil microbial biomass and diversity, a field and glasshouse experiments were conducted in mazandaran province and research glasshouse of ferdowsi university of mashhad, respectively. five experiments were carried out for 5 second crop separately with...
thepetroleum concentrations are contaminant important sources in the environment. hydrocarbon’s contaminants depend on their type and concentration can cause variable toxicity in soils, on the other hand, different kinds of plants also response concentration of contaminant differently, because of the diversity of physiological and morphological characteristics. in this study the effect of diffe...
The aim of investigation was to determine the effects of aspect (north and south) on some morphological [plant height (cm), number of stems per plant, main stem diameter (mm), number of leaves per main stem, petiole length (cm), leaflet length (cm), leaflet width (cm), leaf: stem ratio] and chemical [crude protein (%), crude cellulose (%), calcium (%), phosphorus (%), potassium (%) and magnesiu...
Factor and principal component analyses are widely used in different sciences especially in agricultural science. To determine the factors that create variation between potato cultivars, in normal (non-stress) and water deficit (stress) conditions, two experiments were conducted in the form of randomized complete block design with three replications in summer 2002. Stepwise regression analysis ...

Salvia reuterana Boiss of the Labiatae family is naturally distributed in many parts of Iran. Recent pharmacological studies have confirmed some medicinal properties of S. reuterana including antibacterial, carminative and anti-oxidant effects. In order to domestication of this valuable plant, morphological diversity were studied among seven S. reuterana population (Absard, Delichai, Shahmirzad...
the research was carried out to study the effect of provenance variation on stem length, stem biomass, root biomass and survival ofcaucasian oak (quercus macranthera) seedlings. the seeds were collected from several seed sources grown in an altitude range of 1800-2000 m a.s.l in alborz mountain, both from the northern facing slope, kordkoy and chichal, and from the southern facing slope, roudba...
