in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
One of the main objectives of citrus rootstock breeding is plants free of disease. In order to evaluate the effect of growth regulators on callus induction and regeneration of citrus rootstock, five citrus rootstocks were selected. Seeds were germinated after one month. Culture were incubated at 25 ° C and exposed to 16 hours per day. Explants were cultured on EME medium. Callus induction under...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...
To study the effect of salinity on photosynthesis pigments, fluorescence and antioxidants of three varieties of peanut leaf as an indicator of resistance to salinity, research was carried out as factorial arrangement based on completely randomized design with three replications in the greenhouse of University of Guilan in 2013. The experiment consisted of a combination of 4 different salinity l...
scape bending disorder is the most important factor affecting postharvest loss of gerbera cut flowers. one of the ultimate reasons for gerbera stem bending is lignin, with deformation structural functions and defensive mechanisms. this postharvest experiment was conducted to evaluate the role of phenylalanine ammonia lyase (pal) and peroxidase (pod) enzymes activity in stem bending of two gerbe...
to investigate the effect of sowing density and growth habit on yield, yield components and weed community of red bean an experiment was conducted at research farm of zanjan university, during 2009. the experiment carried out using factorial-split plot design in completely randomized block arrangement with three replications. the main plots, included three red bean cultivars (goli, sayyad and d...
Background: Safflower (Carthamus tinctorius L.), is an important medicinal plant of Asteraceae family, which is a rich source of pharmaceutically active compounds including phenols, flavonoids and fatty acids. In traditional medicine this plant has been used as an herbal medicine to treat various diseases. Objective: The aim of this study was to evaluate the role of jasmonic acid to protect saf...
In order to evaluate cardinal temperatures and optimum thermal range of germination of three medicinal plants including Thymus transcaspicus, Foeniculum vulgare and Calligonumjunceum an experiment was conducted in a Completely Randomized Design with three replications. Therefore, this experiment was conducted to study of the seed germination characteristi...

Abstract Unsuitable concentrations of herbicides, lack of weed control and the severe damage to the plant will cause . Plant growth regulators can play a role in reducing damage . For this purpose, in shahid Bahonar University research greenhouse two experiment was carried out in 1391. The first experiment in a completely randomized design includes selective herbicides in five level, haloxy...
