| Abstract | ||
| The effect of salinity (0, 4, 8 or 12 dSm-1) induced by NaCl in irrigated water was studied on the shoots of wheat cultivars. After 80 days from sowing, fresh and dry weight of shoot and shoot content of Ntot, P, K, Ca, Mg and Cu were significantly decreased as salinity level increased, whereas Na, Cl, Mn and Zn were increased in the shoots of wheat. The highest fresh and shoot dry weight was recorded with Abo-Graib followed by Sham 4 in which both was significantly higher as compared to Rizgary and Semeto. The concentration of Ntot, P, K, Ca, Mg, Na, Cl and Zn showed that there were significant differences among the cultivars. The highest content of Ntot, P, K, Ca and Mg were found in Abo-Graib and Sham 4 and the lowest concentration in Semeto and Rizgary, and opposite was true with Na, Cl and Zn. Indeed, Abo-Graib and Sham 4 cultivar showed significant higher K/Na than Semeto and Rizgary. However, non-significant differences were noticed between Semeto and Rizgary cultivars as well as between Abo-Graib and Sham 4 with regarding to the content of studied nutrients. The results shows that Abo-Graib and Sham 4 cultivars are moderately salt-tolerant compare to the other sensitive salt tolerant Rizgary and Semeto cultivars. | ||
