the present study set out (a) to examine the categories of pedagogical knowledge related to the act of teaching of novice and experienced teachers as gleaned from their verbal report of what they were thinking about while teaching and (b) to compare the categories of pedagogical knowledge of novice and experienced teachers. the aim of comparing these two groups of teachers was to see whether di...
In order to study the effects of salt stress and leaf feeding by ascorbic acid on antioxidant enzyme activity, proline accumulation and lipid peroxidation on leaves and roots of Brassica napus L. cvs. Okapi, an experiment was conducted as a factorial in a completely random design with three replications. Plants were exposed to salt stresses by NaCl solution (200 mM) and foliar were treated by a...
The aim of this study was to investigate the effect of organic acid on alleviation of bicarbonate stress in three grafted peach cultivars on GN-15 rootstock. The experiment was performed as a factorial based on a randomized complete block design during 2017-2019. Factors included peach cultivars (Red Haven, Jh. Hale and Barzegar), calcium bicarbonate (0, 7.5 and 15 mM), and a combination of oxa...
In this research, the effects of 5-aminolevulinic acid, as a key precursor in the biosynthesis of porphyrin compounds such as chlorophyll, in mitigating salt stress were studied in Lycopersicum esculentum mill. Salinity at three levels (0, 50 and 75 mM NaCl) and ALA treatment at three levels (0, 1 and 2 mM) were applied on plants of this species. Both levels of salt (50 and 75 mM) reduced shoot...
this study was aimed to assess of priming effects on soluble proteins and antioxidant enzymes of as a nigella sativa medicinal plant under different levels of salinity and drought. two greenhouse factorial experiments with three replicated randomized complete block design were conducted.treatments included five levels of priming (potassium nitrate 1% and salicylic acid 0.2 mm in 6 hours, potass...
Given the increasing importance of boron (B) toxicity, present study investigates roles glutathione (20 mM, GSH) and proline mM) in improvement wheat (Triticum aestivum cv. Altındane) resistance to B toxicity (10 mM B). The plants were raised hydroponic culture with control, B+glutathione, B+proline, proline. B+glutathione B+proline resisted detrimental influences on root shoot lengths, total c...
In order to investigate the influence of sulfur coated seeds in SCS (a moisture absorbent polymer layer on seeds) on physiological traits of cotton, a field experiment was conducted in completely randomized design with factorial arrangement with 3 replications. Three planting date included early (E), optimum (O), and delayed (D) planting time. Seed coating priming treatments consisted of F (fuz...
Lead is a nonessential element that has a negative effect on plant growth and development. Plant symbiosis with arbuscular mycorrhizal fungi (AMF) in soils contaminated with heavy metals can affect growth of plant, nutrition and tolerance against heavy metals. In this study, the effect arbuscular mycorrhizal fungi Glomus intraradices on the growth, photosynthetic pigments, protein content, prol...
Selenium is an essential element in some organisms, but high concentrations can leading to toxicity in plant. Methyl jasmonate hormone plays an important role in defence processes. In this research, the effect of Methyl jasmonate (Me JA) and sodium selenate (Na2SeO4 ) on growth, content of pigments, phenol, anthocyanin and proline in tomato plants were studied. The seeds to germinate in petri...
Plants are faced with various environmental stresses during their growing period. Each of these stresses have different effects on growth, metabolism and yield according to the sensitivity level and stage of the plant growth. One way of reducing the negative effects of the stresses is to use humic substances. The present study was carried out to evaluate the effects of humic acid and drought st...
