| Abstract | ||||
| A trail was conducted in wiry greenhouse of Crop Physiology Department at Giza Experimental Research Station, ARC, during the two summer seasons of 2014 and 2015 study the alleviation of water deficit stress effects on sesame plant (cv. Shandaweel. 3) by foliar application of ascorbic acid (A.A.) i.e. control, 200 and 400 ppm. Different levels of water were applied i.e. 2600 m3/fad (wet), 2300 m3/fad (moist), 2000 m 3/fad (medium) and 1700 m3/fad (dry). Results could be summarized as follows: - The highest values of plant height, fruiting zone length, leaf area/plant, capsules number and weight/plant, 1000 seed weight were scored from irrigation by 2600 m3/fad followed by 2300 m3/fad with insignificant difference between such two treatments. Whereas, the highest values of shoot dry weight/plant as well as straw and seed yields were obtained when plants irrigated by 2300 m3/fad followed by 2600 m3/fad. While, the lowest values of all growth traits, yield and yield components were obtained when plants irrigated by 1700 m3/fad. Protein content of seed increased and oil content decreased when plants irrigated by 1700 m3/fad (dry). Relative water content (RWC%) decreased gradually with decreasing water applied up to irrigation by 1700 m3/fad. Water consumptive use (WCU) increased with increasing water applied from 1700 to 2600 m3/fad. The heights value of water use efficiency (WUE) was recorded when plants irrigated by 2300 m3/fad. - The foliar application of 400 ppm ascorbic acid significantly increased plant height, fruiting zone length, leaf area/plant, shoot dry weight, capsules number and weight/plant, 1000-seed weight as well as straw and seed yields, protein and oil contents of seeds, RWC, WCU and WUE compared to control and 200 ppm ascorbic acid. -The interaction effect recorded the maximum values of leaf area / plant, capsules number and weight / plant, oil content of seeds, RWC and WUE when plants irrigated by 2600 m3/fad and sprayed with 400 ppm ascorbic acid. Whereas, the highest values of shoot dry weight/plant, straw and seed yields as well as WUE were recorded when plants irrigated by 2300 m 3/fad. and sprayed with 400 ppm ascorbic acid. The maximum value of seeds protein content was obtained when plants irrigated by 1700 m3/fad and sprayed by 400 ppm ascorbic acid. | ||||
