Abstract

Two field experiments were carried out in 2012/ 2013 and 2013/ 2014 seasons at Etay El-Baroud Agricultural
Research Station, to investigate the response of cultivars Sakha 1, Sakha 2, Sakha 3 and Giza 9 to ascorbic and folic acids
addition at 50 and 100 ppm on flax growth, fiber and seed yield and yield attributes and quality. Significant differences
were detected among the studied cultivars, where; Giza 9 cultivar had significantly shorter plants, technical length, lower
plant fresh and dry weights, but it had significantly higher number of fruiting branches, heavier 1000- seed weight, taller
fruiting zone and seed yield per plant and Faddan. Ascorbic and folic acids application, generally, increased all the studied
traits, especially folic acid at 100 ppm concentration, except for, fiber fineness and seed carbohydrate content. Sakha 2
plants treated with ascorbic acid at 100 ppm, had significantly the highest chlorophyll (b) in both seasons, chlorophyll
(a+b) and oil percent in the second season, whereas plants of that variety had the tallest strands when treated with folic
acid at 100 ppm in the second season.
