background and objectives: rice plant requires abundant water during its growth cycle and usually faced with water deficit. drought  stress alters the allocation assimilate , root and shoot growth during the vegetative period and also lower tillering, death tillers, lower plant height and flowering delay. the aim of this study was to screen different iranian genotypes and some lines from irri w...

laboratory studies were conducted to examine the effects of different concentrations of wild barley (hordeum spontaneum koch.) shoot and seed extracts on germination and seedling growth of wheat (triticum aestivum l.) and wild barley. in this study, all wild barley shoot extract concentrations (with exception of lowest concentration) significantly reduced wheat seed germination after 7 days. sh...

In order to assess relationship between ion transport and variation in growth responses of four canola cultivars under salt stress, four canola cultivars were grown at 0 and 150 mM NaCl for six weeks in hydroponics. Salt stress reduced the shoot and root fresh and dry weights of all canola cultivars. Maximum shoot fresh and dry weights were recorded in Dunkeld under both non-saline and saline c...

This study was carried out to determine the effects of cadmium (Cd) (0 and 2 mg kg-1 soil) and salt stress (NaCl 0 and 3000 mg kg-1 soil) on shoot dry weights and shoot Cd, sodium (Na) and potassium (K) concentrations of salt-tolerant (Maverik) and salt-sensitive (RX-9292) hybrid maize varieties. Plants were grown under controlled greenhouse conditions for 19 days. Shoot dry matter productions ...

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 ...

Seeds of 4 cultivars of chickpea (2 desi, CSG 8962 and DCP 92-3, and 2 kabuli, CSG 9651 and BG 267) were grown under 0, 4, 6 and 8 dS m levels of salinity until maturity. Shoot and root dry weights, root shoot ratio and various yield parameters were evaluated under salinity at 40, 70 and 100 days after sowing. Salinity significantly reduced dry matter accumulation in both roots and shoots in al...

thyme (thymus vulgaris l.) is an aromatic and medicinal plant which is very important for the herbal industry. in this research, in vitro selection for nacl tolerance was investigated in this plant. hypocotyl and shoot explants (apical meristem and cotyledonary leaves) of sterilized seedlings were cultured in ms medium supplemented with different combinations of 2, 4-dichlorophenoxyacetic acid ...
