An outdoor pot experiment was carried out in sand+ coco-peat culture (80:20 ratio) to investigate the response of nitrate reductase activity and nitrate accumulation in roots and leaves of fifteen Iranian landraces of spinach (Spinacia oleracea) at different stages of plant development. Plants were tested during a three periods from 22, 30 and 38 days after emergence of first true leaves and be...

anise hyssop is a prennial herb belonging to the lamiaceae family. essential oil of this plant is used in food, pharmaceuticals, cosmetics industries as well as flavoring liqueurs. since water stress affects the growth, productivity, as well influences the active principles governing medicinal plants, in this research the effect of different water deficit stresses on such morphological traits a...

Bromus danthoniae Trin. is an annual grass species that is well adapted to harsh climates and could be considered as an important genetic resources for tolerance to environmental stresses such as salinity. In this study, 24 genotypes collected from Ilam, Kurdistan, Kermanshah (non-saline areas) and West Azerbaijan (saline area: shores of Uremia Salt Lake) provinces of Iran were investigated at ...

Plasticity of the phenotypic architecture of wild barley, Hordeum spontaneum, was studied in response to water and nutrient stress. Direct and indirect selection on several vegetative and reproductive traits was estimated and path analysis used to reveal how regulating pathways via maternal investment differed between environments. Vegetative traits displayed differential regulating effect on f...
