The effect of optimal and supra-optimal concentrations (0, 250, 500 and 750 mM) of NaCl on the growth, chlorophyll, soluble carbohydrate and proline content, ion concentrations and antioxidant enzyme defence of Sesuvium portulacastrum was studied. A significant increase in growth and tissue water content was observed in the shoots exposed to 250 mM salt. Minimum damage to the membrane in terms ...
Salinity is considered as one of the main limiting factors for growth and production of several agricultural crops all over the world. Also, salinity influences the growth and also synthesis of secondary metabolites of medicinal plants. Salvia viridis and Salvia spinosa are two aromatic species which belong to Salvia genus from Lamiaceae family. As the mechanisms of salt stress tolerance and al...
In order to evaluate the effect of Inoculation by pseudomonas plant growth promotinh rhizobacteria and foliar application of boron-nanochelate of pea( Pisum sativum L.) mother plants on germination traits and seedling growth of produced seeds under Cadmium stress a factorial experiment based on completely randomized design with four replications was conducted. Experimental treatments were 12 c...
Saline–alkali stress is one of the major factors limiting oat seed germination. The regulatory role melatonin (MT) as a naturally occurring active substance well known, but mechanism MT-mediated intrinsic physiological regulation germination under saline–alkali unclear. Therefore, this study investigated (1) variability different MT soaking concentrations and times on seeds stress, (2) possible...
The effect of bio-fertilizers and super-absorbents on the modification water-deficit stress was studied in castor. A field experiment conducted with a split-plot design based completely randomized block three replications. first factor included four levels (70, 100, 130, 160 mm evaporation pan Class) main plot; sub-factor application bio-fertilizer treatments (Azospirillum, Citrobacter, Azospir...
To ward off pathogens, plants establish innate immunity system in which salicylic acid (SA) plays an important role. The downy mildew of foxtail millet (Setaria italica) is oomycete disease caused by biotrophic pathogen Sclerospora graminicola, seriously affects the yield and quality millet. However, it not clear how SA regulating defense responses In this study, we found that spraying exogenou...
In order to investigate the effect of dehydration stress and planting date on some physiological indices and growth of Cymbopogon citratus, a field experiment in the form of a split plot in a randomized complete block design with 3 replications, including 3 levels of different irrigation (100% full irrigation as a control, 75 and 50% full irrigation) and 3 levels of planting date including 20 M...
using plant growth regulators at the stresses environment can improve plant growth and crop production. hence, in this research response of photosynthesis rate, chlorophyll, soluble sugar and flower dry weight of chamomile to methyl jasmonate under different salinity levels was studied. values of 0 (control), 75, 150, 225 and 300μm methyl jasmonate (meja) with salinity levels of 2, 6, 10 and 14...
The synthesis of a proline-rich cyclic heptapeptide, fanlizhicyclopeptide A (8), previouslyisolated from the fruits of Annona squamosa (sugar-apples), is described via coupling oftetrapeptide l-prolyl-l-tyrosyl-l-leucyl-l-proline methyl ester with tripeptide Boc-glycyl-lvalyl-l-proline followed by cyclization of the linear fragment having seven amino acid units.Structure of the synthesized cycl...
in order to study the effects of soil and foliar application of fe-eddha on some biochemical and physiological traits in safflower under two irrigation regimes an experiment was conducted in 2008 growing season in research field of faculty of agriculture, shahed university. the experimental design was a split-plot based on randomized complete blocks with four replications. mainplots consisted o...
