Abstract. Information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. Vetiver grass (Vetiveria zizanioides) is a non-native perennial grass that was introduced to the Iran in 2008. This plant is a multi use species that could be considered from different viewpoints. Thus, it...

this research was carried out at the research farm, faculty of agriculture, bu-ali sina university in growing season of 2011-2012. the aim of research was to evaluate the effect of foliar application of nano-iron chelate and bacterization of mesorhizobium bacteria on root nodulation, growth, grain yield and yield components of chickpea under rainfed conditions. a randomized complete block desig...

xanthine oxidase plays crucial roles in the production of reactive oxygen species (ros), and uric acid in blood which may lead to gout, one of the oldest known forms of arthritis amongst humans. summer savory (satureja hortensis l.) a medicinal/spice exhibits antioxidant activity, but unknown effects on xanthine oxidase activity. here, for the first time, we examined the effects of s. hortensis...

Latex and cell-free extracts of various organs and stages of plant and capsule development in Papaver somniferum, the opium poppy, synthesized dopamine, an alkaloid precursor, from 14C-dopa. The 1000 g X 30 min supernatant from latex of the pedicel-capsule junction converted more dopa than latex supernatant from the upper capsule or lower pedicel regions, although there was more protein in the ...

Transgenic tobacco (Nicotiana tabacum L, cv. SR-1) expressing mannitol 1-phosphate dehydrogenase, MTLD, in chloroplasts and myo-inositol O-methyltransferase, IMT1, in the cytosol after crossing of lines which expressed these foreign genes separately has been analysed. Plants expressing both enzymes accumulated mannitol and D-ononitol in amounts comparable to those following single gene transfer...

Although herbivory can occur throughout a plant’s life, little is known about relative fitness impacts of damage at different life stages. In the long-lived monocarpic wildflower, Ipomopsis aggregata (scarlet gilia), for example, the response to browsing by ungulates in the year of flowering has been studied extensively, whereas damage and its fitness consequences during the preceding years of ...

The chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of A. annua was analyzed by GC and GC/MS and sixty-two components were identified. The main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). The full-flowering oil contained predominantly caryophyllene (19.4%), germacrene D...
