Phytochrome control of cucumber seed germination is temperature-dependent. A prolonged exposure to radiation from broad spectrum far red sources (Pfr/P = 0.05 to 0.07) prevents germination at temperatures below 20 C. Above 20 C there is no inhibition and it appears as if there is an escape from phytochrome control. However, radiation from a monochromatic, narrow band 730 nanometer source (Pfr/P...

abstract: the commercial development of food products originated from the plants as sources of antioxidants to increase the health benefit and stabilize the food is of current interest. this study was aimed at obtaining dill extract using cold solvent method by three solvents, (methanol, acetone, and hexane) and examining the antioxidant potency and determining the oxidative stability of sunflo...

In a greenhouse experiment, two strains of plant growth promoting rizobacteria (PGPR) mixture of (ICARDA-441 and ARC-202) as seed inoculants, and white willow (Salix alba) extract as foliar and seed treatment were tested for induction systemic acquired resistance (SAR) in faba bean plants against Bean yellow mosaic virus (BYMV). The results demonstrated that BYMV challenged plants emerged from ...

When seeds of soybean were subjected to accelerated aging, the amount of total lipid which was extracted from the whole seed increased with "age," whereas the extractable phospholipid decreased slightly. This small decline primarily reflected changes in the amounts of phosphatidylcholine and phosphatidylethanolamine. The levels of unsaturated fatty acids in the whole seed and in the seed axis s...

Phenolic compound profiles were investigated by HPLC-MS in two consecutive years to assess genotypic variation in berry skins of nine red Vitis vinifera cultivars. The results showed that the types and levels of phenolic compounds greatly varied with cultivar. Common wine grape cultivars such as Syrah, Cabernet Sauvignon, Cabernet Gernischt and Merlot contained more types of anthocyanins, flavo...

Chloasma (melasma), an acquired hypermelanosis, is often recalcitrant to various treatments and an amenable, as well as safe, pigment-reducing modality is needed. We investigated that the reducing effect of proanthocyanidin, a powerful antioxidant, on chloasma in a one-year open design study. Proanthocyanidin-rich grape seed extract (GSE) was orally administered to 12 Japanese woman candidates ...

introduction: regarding chronic nature of epilepsy and its side effects and to access the effective treatment procedures, herbal medicine has received remarkable interest. the aim of this study was to determine the anticonvulsant effects of hydro-alcoholic extract of anethum graveolens seed on pentylenetetrazol (ptz) -induced seizure in male mice. methods: fifty-six albino male mice were divide...

to study seed dormancy and the after-ripening period in barley genotypes (57 dutch genotypes and two iranian cultivars (gorgan and valfair)), an experiment of randomized complete block design (two replications) was conducted at the research farm of collage of agriculture and natural resources, university of tehran in 2004-2005. in the growing stage of zgs92, panicle was collected. the percentag...
