Despite the numerous studies on the effect of the magnetic field on plants, the exact mechanism of these effects has not yet been determined. The aim of this study was to compare the effect of magnetic field on growth and photosynthetic characteristics of two almond species (Amygdalus scoparia and A. eburnea). For this purpose, 21-day-old almond plants were affected by 10 mT static magnetic fie...

Field microplot experiments were conducted from 1995 to 1998 to determine the relationship between fresh shoot weight of stalk-cut broadleaf and shade-grown cigar wrapper tobacco types (Nicotiana tabacum L.) and initial density of Globodera tabacum tabacum second stage juveniles (J2) per cm(3) soil. Total shoot weight was negatively correlated with initial nematode densities of 12.3 to 747.3 J2...

in order to study the effect of pyridate, bentazon and imazethapyr herbicides on chickpea growth, nodulation and biological nitrogen fixation, a greenhouse experiment was conducted at ferdowsi university of mashhad in 2010. experimental type was completely randomized design with four replications. treatments included pyridate, bentazon and imazethapyr herbicides application in 1200, 720 and 75 ...

The aim of this study was to identify the effect of Spermine and Salicylic acid on several growth parameters, such as shoot length, shoot fresh and dry weights, amount of protein and carbohydrate, of Badami and Qazvini pistachio cultivated variety under copper stress. The experiment design was completely randomized with three replicates per treatment and four levels of copper (o.5, 30, 45, 60 µ...

in order to comparison the foliar application of biological, biostimulator and chemical fertilizers on growth characteristics and yield of saffron, a factorial experiment was conducted in a completely randomized block design with four replication in 3- year field of saffron in dargaz, khorasan razavi province from 2010 to 2011. the first factor had 5 levels included biostimulator fertilizer bio...

to evaluate the effect of limited application of nitrogen (n) on the height control of geranium(pelargonium hortorum) and improving its quality performance, an experiment was conducted based on acomplete randomized block design with three replications in the greenhouse environment through theyears 2011-2012. geranium seedlings were cultivated in the pots filled with peat-based substrate (peat, ...

the present research was carried out under hydroponic culture to evaluate the interaction between salicylic acid (sa), nickel (ni) on vegetative and reproductive growth of strawberry plants as a factorial experiment in a completely randomized design. well-rooted daughter plants of pajaro cultivar, were potted in 3 l plastic pots and were sprayed with sa at concentrations of 0, 1, 2 and 3 mm and...

Environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in Iran. For cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. In this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...

The study was made in order to evaluate the response of fifteen wheat genotypes (grown in Pakistan) to sodium chloride salinity at seedling stage keeping two levels of salinity (150 and 200 mM NaCl) along with a control (no application of salt). The effect of varieties on shoot length of wheat was non significant. Maximum shoot length was recorded in MH-97 (15.55cm) while minimum shoot length w...
