| Abstract | ||||
| In pot experiment were carried out in the Experimental farm, Faculty of Agriculture, Fayoum University, during two successive seasons of 2006/2007 and 2007/2008 to investigate the effect antioxidants, namely, ascorbic acid, citric acid and vitamin B each alone, at the rates of, 100, 250 and 500 ppm on improving the growth, yield and some chemical constituents of fennel plants grown under saline reclaimed soil conditions. The obtained results showed that the treated fennel plants with ascorbic acid, citric acid and vitamin B reduced the harmful effect of soil salinity and improved plant growth characters expressed as plant height, number of branches, fresh and dry weights of herb plant-1, number of umbels plant-1, diameter of umbel, fresh and dry weights of umbels plant-1 and weight of seeds plant-1, as well as, yield of essential oil, total chlorophylls and carotenoids content, total carbohydrate and N percentage. Generally, the highest rate of antioxidants substances (500 ppm) gave the best results on the above characters which studied and were arranged as vitamin B followed by ascorbic acid then citric acid. | ||||
