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.
