Cadmium (Cd) toxicity in plants leads to serious disturbances of physiological processes, such as inhibition of chlorophyll synthesis, oxidative injury to the plant cells and water and nutrient uptake. Response of Matricaria chamomilla L. to calcium chloride (CaCl(2)) enrichment in growth medium for reducing Cd toxicity were studied in this study.(More)
An investigation was carried out to find out the extent of changes occurred in two safflower (Carthamus tinctorius L.) cultivars in response to water deficit stress. Two safflower cultivars namely IL.111 and Isfahan were used for the study. Thirty days after sowing, plants were grown under soil moisture corresponding to 100, 85, 70 and 55% field capacity(More)
In this experiment, the possibility of enhancing the water deficit stress tolerance of chamomile (Matricaria chamomilla L.) during two growth stages by the exogenous application of hexaconazole (HEX) was investigated. To improve water deficit tolerance, HEX was applied in three concentrations during two different stages (50 and 80 days after sowing). After(More)
Morphological and biochemical responses of feverfew plants exposed to low (5 μM) and high (35 and 70 μM) levels of Cd or Cu were investigated. Increasing metal supply notably reduced the plant biomass. Elevated Cd and Cu levels also resulted in an increase in the leaf proline content. Besides, decrease in ascorbic acid (AsA) and glutathione (GSH) contents(More)
The accumulation of plant defense metabolites is closely associated with the concentration of nutrient elements, yet data related to the interactive effects of two nutrients on the deployment of phenolics and terpenoids are scare. In the present study, the interaction between magnesium (Mg) and manganese (Mn) on nutrient uptake, photosynthesis, oxidative(More)
A balanced nutrient supply is a critical factor affecting accumulation of terpenoids in plants, yet data related to the interactive effects of two essential nutrients for the biosynthesis of sesquiterpenes are scarce. Here, the interactional effects between magnesium (Mg) and manganese (Mn) on plant growth, oxidative status, parthenolide accumulation and(More)
Accumulation of defense metabolites is an adaptive response to heavy metals in plants. However, deployment of multiple classes of defense metabolites under cadmium (Cd) and copper (Cu) toxicity is not understood. Here, the responses of parthenolide and phenylpropanoids were examined. Quantification of parthenolide and phenylpropanoids, and the expression of(More)
In this experiment, Five N efficiency parameters, seed yield and seed oil content was investigated under different fertilizer management in field-grown canola plants. Treatments include four levels of nitrogen (zero, 50, 100 and 150 kg ha) as main factor and two levels of zinc sulfate (zero and 50 kg ha) and two levels of biological fertilizer (with and(More)
