The present research aimed to determine the relationships between the intent attribution, social goals, and self-efficacy perception in gifted children with their behavioral responses to the ambiguous stimuli. In addition, the children’s responses in different groups, including withdrawn, aggressive and problem solved children to the social goals and self-efficacy perception components have been examined. In order to test the hypotheses, the Asher and Erdley questionnaire was applied. In the first phase, all of gifted school students in grade six (N=370) were asked to complete the questionnaire. In the second phase, with regard to the data analyses 195 students have been selected from the main population and the questionnaire was repeated for them. Results showed that the gifted children groups were significantly differed in their responses to the "social goals" and "self-efficacy perception" components. In particular, in response to the ambiguous stimuli, the aggressive children stressed on the anti-social aims, while, the withdrawn and problem-solved children were more likely to prefer the socialized styles.

In present investigation, vegetative compatibility groups (VCGs) of39 isolates of Fusarium graminearum collected from four provinces(Golestan, Mazandaran, Kerman, and Hormozgan) were determined using nitrate non-utilizing(nit) mutants. Results showed that with the exception of a single isolate (Fg-196)all the remaining isolates were forced to produce nit mutants on MMC and PDC media containing potassium chlorate. In total, 375 nit mutants were obtained of which, 72.5% were synthesized on MMC and 27.5% on PDC medium. On the basis of colony characteristics on basal medium containing one of the five nitrogen sources (sodium nitrate, sodium nitrite, ammonium tartarate, uric acid, and hypoxanthine) three nit mutant phenotypic classes were determined. Of these, 33.2% belonged to nit I, 28.2% to nit3, and 38.6% to nit M. To determine VCGs and complementation tests, pairing were made between all nit M and nit 1and I or nit3. In a compatible reaction between nit M and two other nit mutants, a dense growth at the line of contact between two colonies was formed after 5-14 days. But a much weaker similar phenomenon taking more than 14 days was observed, when nit 1and nit3 mutants were paired. All isolates examined in this study, were grouped nito 24 VCGs of which 14isolates, all from Goleston and Mazandarn provinces belonged to VCG 1, two isolates to VCG2 and each of the 22 remaining isolates (with various geographic origins) were classified in a separate VCGs. None of 39 isolates tested exhibited vegetative self-incompatibility reaction. In addition, no correlation was found between VCG2 and relative virulecnce of isolates.
