Hydroponic experiments were conducted to investigate vanadium uptake by Chinese green mustard and tomato plants and its effect on their growth. Twenty-eight (Chinese green mustard) and 79 days (tomato) after germination, the plants were exposed for a further seven days to a solution containing six different concentrations of ammonium metavanadate (0-80 mg/l NH4VO3). The vanadium accumulated in ...

Soil salinity is an increasing environmental stress on crops in most areas of Iran since farmers use underground saline water for irrigation. In order to investigate the effects of salt stress on germination and seedling growth of safflower (Carthamus tinctorius L.), an experiment was conducted at two stages (germination seedling growth), using four levels of NaCl salinity (0, 5, 10, 15 ds/m), ...

In order to study the effects of water deficit and foliar application of salicylic acid and spermine on dry matter production and biochemical and morphological treats of Echinacea purpurea, a split plot experiment was conducted based on randomized complete block design with three replicated during 2016- 2017 growing seasons at research field of Institute of Forests and Rangelands, Iran. In this...

Silybum marianum is an important medicinal plant with high antioxidant properties. Static magnetic field (SMF) is a kind of abiotic stresses which can affect growth and antioxidant capacity of medicinal plants. In this research, the effects of SMF on total phenolic and flavonoid contents, radical scavenging activity, and anatomical alterations were investigated in S. marianum seedlings. Five-da...

understanding of wheat root system is important in dryland conditions. root development, important factor in wheat production under water limiting conditions, can be affected by environmental factors especially nitrogen fertilizer. a field experiment was carried out to study the nitrogen rates and application times on root morphology of three rainfed wheat genotypes, using a split-splitplot bas...

Opportunities exist for replacing reduced height (Rht) genes Rht-B1b and Rht-D1b with alternative dwarfing genes, such as the gibberellin-responsive gene Rht12, for bread wheat improvement. However, a comprehensive understanding of the effects and mode of action of Rht12 is lacking. In the present study, the effects of Rht12 were characterized by analyzing its effects on seeding vigour, seedlin...

To investigate the effects of saline stress on seed germination, ion distribution, and organic solutes changes of sunflower (Helianthus annuus L.), in the present study, seeds and 3-week-old seedlings were subjected to a series of external NaCl concentrations (5–200 mmol). The results showed that high salinity (200 mmol) remarkably inhibited the germination of seed and delayed germination time ...

In order to study the effects of steroidal testosterone hormone on seedling growth, antioxidant enzyme activity and also on callus induction from leaf explants of German Chamomile (Matricaria chamomilla L.) under in vitro culture, an experiment was conducted based on completely randomized design with three replications using MS medium containing different concentrations of testosterone (0, 0.01...
