to study the effect of salinity stress on seed germination and seedling growth of four medicinal plants, nigella sativa l., cannabis sativa l., trigonella foenum graecum and cynara scolymus l. an experiment was conducted in the botany laboratory of islamic azad university, birjand branch. a completely randomized design (crd) with 3 replications was used as separately for each species. treatment...

identification of quantitative trait loci is one of the important issues in breeding program especially under stress condition. plant material in the present study was a natural population including 72 tobacco genotypes. in order to apply osmotic stress, mannitol with 0.33 molar concentrations was used. the genotyping of individual were performed using 21 out of 35 primer combinations of aflp m...

in order to evaluate the allelopathic effects of white top (cardaria draba (l.) desv.) water extracts on corn and canola germination characteristics, an experiment was carried out based on crd design with three replications in agronomy research lab of yasouj university. treatments were included of 25%, 50%, 75% and 100% water extract (50 gr dm/l) of root, leaf and stem, inflorescence and whole ...

in order to study the response of coriander medicinal plant to salt stress, two experiments were conducted for germination and vegetative stages. this study was carried out as a factorial experiment based on completely randomized design with three replications. the treatments were salinity at five concentrations including 0, 25, 50, 75 and 100 mm nacl. response of coriander seeds germination in...

Copper is one of the heavy metal in plant that causes toxicity at high concentration via producing reactive oxygen species. Nitric oxide can protect cells from oxidative stress produce by reactive oxygen species. Effect of different concentrations of copper (1000, 1500 and 2000 μM) and interaction with nitric oxide (100 and 150 μM) were studied on growth parameters (shoot and root length) and s...

Nanoparticles are atomic or molecular particles with at least 1–100 nanometer diameters. They have entered vastly into the world of agriculture and biology; this is because of their special effect and their unique features. Their unknown impact on living things and the ecosystems has caused a lot of concern. This research was done in order to study the effects of nano-TiO2 and nano aluminium on...

a greengouse experiment was conducted to evaluation of salinity stress on growth parameters of two olive cultivars during 2013-2014 at agricultural and natural resources research center of tehran. in the experiment, effects of five levels of irrigation water salinity including 0, 4, 8, 12 and 16 ds.m-1 were evaluated on ʻzardʼ and ʻmissionʼ olive cultivars under soilless culture. data showed th...

Plant growth and development was affected greatly through salinity. Appropriate nutrients application on salinity condition can reduce its harmful effects and increased productivity of salinized soils. A pot experiment was carried out in 2007 in cs Lab., Department of Agronomy, Kyungpook National University, Korea to assess the effects of potassium nitrate on Gycine max (Var. Daewonkong) under ...

in order to evaluate the relationships between some traits of iranian rice seedlings under saline conditions,,75 iranian cultivars as traditional, improved and introduced cultivars were used, as a randomized complete block design experiment with 3 replications at rice research institute of iran in three levels of salinity (normal ,1.2 , 4 and 8 ds.m-1) in 2006. root and shoot length, root and s...
