To study inheritance of resistance to septoria tritici Blotch in wheat, the generation mean analysis method was used. So six generations (P1, P2, F1, F2, BC1 and BC2) were planted under completely randomized design with three replications in greenhouse. Seedlings were inoculated at the second-leaf stage with an isolate of Septoria tritici and Necrosis and Picnidia density and Area Under Disease Progress Curve for both traits (Necrosis and Picnidia) were evaluated. Results of generation mean analysis showed that the additive, dominance and epistatic effects were effective in all traits, but the role of dominance effects and dominance × dominance interactions was more important. The results of the estimated degree heterosis and potance ratio confirmed the more importance of dominance effect in genetic control of studied traits. Average broad sense heritabilities were between 73 and 93.6 for all traits. Degree of dominance being more and less than one, confirmed dominance and overdominance gene effects. Therefore, it is recommended to use the breeding methods based on hybridization and or selection in final generations to improve resistance to Septoria tritic blotch.

Documenting the production process in agriculture includes providing all information and activities that shows the course of production from seedbed preparation stage to harvest stage. For this purpose, in present investigation all management operations performed from seedbed preparation stage to harvest stage in the studied wheat fields in 2007 and 2008 were recorded through farms survey. In this study, the method of doing each management operation undertaken in farms from stages of seedbed preparation to harvest as well as a proportion of farmers applying different method of the management operations were determined through absolute and cumulative frequency distribution. The results showed wheat cultivation was conducted from 5 to 16 December. Depending on seedbed preparation quality and type of planting tool, the rate of used seed was varied from 140 to 250 kg ha-1. The more farmers used urea, triple superphosphate and potassium sulfate fertilizers for supplying nutrient requirement in wheat farms. Traditionally, urea fertilizer was used at stem elongation stage on average with amount of 93 kg ha-1. Due to shortage rainfall during the first year, the most farms were irrigated twice (at flowering and early seed filling) but in the second year it was done once (at flowering). The time of wheat harvest was ranged from 7 to 14 June depending on environmental condition. In respect to variation of management operations in farms, the amount of yield was varied from 2.5 to 6.3 t ha-1.

Based on the valuable antioxidant activity of citrus fruits, in present study the effect of rootstock and the type of tissue on some fruit quality parameters including phenol, flavonoid, antioxidant and the content of hesperidin and naringin of orange and mandarin was studied. The experiment was conducted as a factorial design based on complete randomized blocks with four replications. Results showed that, the amount of titrable acid of thampson novel fruit was higher than that of page mandarin. Both fruits produced a higher titrable acid when citromelo was used as rootstock. The content of vitamin C of fruits of sour orange was higher than that of citromelo. Antioxidant activity and the content of total phenol, total flavonoid, and hesperidin of thampson novel fruits were significantly high. Contrary to the hesperidin, between thampson novel orange and page mandarin the content of naringin of page mandarin was at the highest level. Fruits on citromelo showed a higher antioxidant activity, flavonoid and hesperidin content. No difference on the amount of total phenol and naringin was observed between two different rootstocks. The accumulation of measured antioxidant compounds of peel is noticeable. Finely based on the obtained results it can be concluded that although the concentration of pharmaceutical and nutritional compounds strongly related to genetic, it seems that a higher quality and quantity of such compound could be achieved using a suitable rootstock.

This study was carried out to evaluate the N nutrition status of 16 selected wheat fields in Gorgan during 2006-2007 growing season. Based on the obtained results, dry matter yields of fields were varied from 0.38 ton ha- at the beginning tillering to 12.51 ton ha- at the harvesting maturity. The mean of N concentrations (%) in plant dry matter were 3.09 at beginning tillering, 2.60 at complete tillering, 1.62 at at stem elongation, 1.56 at boot stage, 1.14 at the beginning watery ripe stage and 1.08 at harvesting maturity. These results indicate that the most reduction in N concentration occurred in stem elongation stage, and that N concentration in plant dry matter decreased as plants developed. Actual N concentrations in dry matter were substantially less than critical N concentrations at all development stages; The means of critical N concentrations at above mentioned development stages were 4.38, 4.33, 2.88, 2.32, 1.95 and 1.72, respectively. Then, the means NNI for 16 wheat fields were very lower than optimum (NNI=1) at all development stages; 0.71 at beginning tillering, 0.59 at complete tillering, 0.57 at stem elongation, 0.68 at boot stage, 0.59 at the beginning watery ripe stage and 0.61 at harvesting maturity.
