| Abstract | ||
| THE CURRENT study was conducted at the University of Mosul/ College of Education for Pure Sciences / Department of Biology, where an experiment was carried out in the wired house by cultivating wheat variety (buhuth 22). The plants were exposed to two dry periods (6, 9) days and three levels of light intensity (100%, 75%, 35%), and the shoots were sprayed with three concentrations of ascorbic acid (0, 100, 200ppm) to see their effect on physiological characteristics and the results were analyzed statistically using a complete random design (C.R.D) with three replicates. The results showed that drought had a negative effect on plant height, leaf area, relative water contents, total chlorophyll and carotenoids, at the second dry period, with a percentage of 17.12, 36.02, 9.70, 28.57, and 30.26%, respectively, compared with their controls treatment, while plants growing under normal light intensity (100%) outperformed in the characteristic of plant height and total chlorophyll, while there was an increase in the leaf area and relative water content with reduced light intensity compared to normal lighting. On the other hand, the interaction of ascorbic acid, drought and the intensity of lighting had a positive effect on plant growth in most of the studied physiological characteristics. | ||
