| Abstract | ||
| The study was conducted in the glass house in order to study some physiological responses of five wheat cultivars (IPA 970082,VEE(s), IPA970110, ACSAD881 and ACSAD907). Exposed to drought and reirrigation condition and grown under different leaels of nitrogen. The results showed that the exposure of treated plants with nitrogen especially at the concentration (30 ppm) to drought episode (which induced by holding irrigation water from the soil for 30 days to obtain wilting point) led to improve plant growth by increasing the dry weight of shoot, root systems, its carbohydrate, calcium and magnesium content. Increasing the concentration of nitrogen treatment up to (60ppm) led to increase protein content of wheat plant in comparison to untreatment plants which nitrogen and exposed to drought period. Reirrigation of of wheat plants which had been exposed to drought period led to increase plant growth and its content carbohydrate and mineral elements comparison to the plant without irrigation. | ||
