effects of seed priming by salicylic acid on some morpho-physiologic characteristics and yield of cowpea (vigna unguiculata l.) cultivar “parastou” was investigated under water deficit. experiment was conducted as a split block design with 3 replications in 2008-2009 at research farm of zanjan university. factors were including drought stress as a main factor in 2 levels (irrigation, water defi...

an efficient transformation system for the medicinal plant portulaca oleracea was established using agropine-type agrobacterium rhizogenes atcc15834. hairy roots were obtained directly from cotyledon leaves explants seven days after inoculation with the bacteria. the highest transformation efficiency was obtained from cotyledon leaves explants, and amounted to 53.3% within two weeks. roots grew...

AIMS To determine serum salicylic acid concentrations in non-vegetarians and vegetarians not taking salicylate drugs, and to compare these concentrations with those found in patients taking aspirin, 75 mg daily. METHODS Serum samples were obtained from vegetarians (n = 37) and non-vegetarians (n = 39) not taking salicylate drugs. Non-vegetarians and vegetarians were recruited from the communi...

This study was conducted to determine the effect of foliar salicylic acid (SA) and citric acid (CA) applications on growth, biochemical characteristics and essential oil content of thyme (Thymus vulgaris L.) grown under field conditions. Salicylic acid (0.5 and 1 mM) and citric acid (5 and 10 mM) were applied three times during the vegetation at 15 day intervals. Results revealed that foliar ap...

salicylic acid (sa) plays a key role in plant disease resistance and hyper-sensitive cell death but is also implicated in hardening responses to abiotic stress. the aim of this study is to examine the effects of salicylic acid on the growth, eco-physiological and biochemical characteristics in zinnia elegans plant exposed to copper stress. effects of copper (cu) on biomass, root length and shoo...

OBJECTIVE To evaluate maternal and neonatal plasma concentrations of acetylsalicylic acid and salicylic acid and the neonatal endogenous prostanoid formation during low-dose aspirin prophylaxis (LDA; 100 mg daily) in pregnant women. METHODS Concentrations of acetylsalicylic acid and salicylic acid in maternal plasma after at least 4 weeks of LDA (n = 14) and in umbilical cord plasma of newbor...

Evening Primrose oil (Oenothera biennis L.) is a rich source of Gamma linolenic acid (GLA) and other useful unsaturated fatty acids. Despite the diversity of sources of GLA, due to better absorption in the human body, evening primrose oil is the main source of GLA. In this study, the effects of pollination, harvesting method and application of salicylic acid on yield, yield components, and qual...
