Application of both antioxidants increased significantly all growth and yield characteristics as well as improvement root structure. Moreover, salt induced reduction in growth and yield and its quality ameliorated by exogenously applied antioxidants, in particular, ascorbic acid (AsA) due to increasing all mentioned characters as compared to untreated plants under corresponding salinity level. Anatomically, increasing salinity levels decreased thickness of adventitious root, vascular cylinder, and thickness of either epidermis or metaxylem vessels. Treatment with either ascorbic acid or α-tocopherol at 100 mg/L and their interactions with salinity increased all the above mentioned parameters in both nonsalinized and salinized plants. Ascorbic acid is the most effective in this concern.

Application of micronutrients combined mixture under high nitrogen rate produced the highest values of plant growth, yield and physiological characteristics compared with other treatments. The second rank best treatment was observed with applications of Zn, then Mn treatment. Cu and Fe treatments were equal in its effect and the differences between them were insignificant in the most cases. Application of nitrogen rate up to 90 kg/fed increased gradually all studied characters. Anatomically, application of combined mixtures of micronutrients under high nitrogen rate increased significantly all anatomical characteristics of flag leaf or culm, in particular, number of vascular bundles and thickness of mechanical tissue in culm as well as dimension of vascular bundles, diameter of metaxylem vessels, and thickness of epidermis in both flag leaf and culm. Furthermore, thickness of mesophyll parenchyma and midrib region in flag leaf was also increased. In conclusion, the obtained results show that foliar application of combined mixture of studied micronutrients (Cu, Mn, Fe and Zn) at the rate of 500 ppm from each under moderate (recommended rate) or high rate of nitrogen fertilizer (70 or 90 kg N/fed) can be recommended to maximize wheat growth and grain yield per main spike and per plant.}, keywords = {Wheat,Micronutrient,nitrogen,culm anatomy,leaf anatomy,Growth}, url = {https://jpp.journals.ekb.eg/article_86565.html}, eprint = {https://jpp.journals.ekb.eg/article_86565_934226b9e56e3b0d7d132cc107eb0fed.pdf} } @article { author = {Massoud, Hekmat and Abd El-Latif, T. and Badawy, Doaa}, title = {EFFECT OF CUTS AND DIFFERENT DRYING METHODS ON VOLATILE OIL QUANTITY AND QUALITY OF SWET BASIL (Ocimum basilicum L.)
