تأثير حامض الجبريليك والزنك في الحاصل وبعض صفات المحتوى الكيميائي والمعدني لبذور العصفر Carthamus tinctorius L.

The experiment aims to study the effect of splashing Gebberellin by levels 0 , 5 , 10 ppm on green groups of safflower plants Carthamus ctorius L. which are growing in soil mixed with Zinc at levels 0 , 300 , 400 , 450 , 600 ppm the crop, seed's content of protein , carbohydrates and mineral synthesis of safflower. The results appeared that the treatment of soil with zinc especially at concentration 300 ppm which led to increasing yield through increasing number of seeds / head and biological crops weight / plant , also the treatment led to moral increasing in content of safflower seeds of protein and carbohydrates incomparisin with other. In other hand the result appeared that splashing safflower by Gebberellin especially at concentration 10 ppm. led to increased the ione concentrations of calcium , magnesium , sodium , potassium for seeds , also there was inceasing of biological crop weight ; while high concentration 600 ppm led to decreasing number of heads and seeds / plant and in protein , carbohydrates and mineral synthesis. Splashing by increasing levels of Gebberellin on the green groups of growing plants under pollution conditions with Zinc , especially at 600 ppm led to improvement growth , crope chemical contents and protein production . Because of deficiency studies about regulation mechanism between the effect of pollution by heavy minerals in inhibition and the effects of other compounds like Gebberellin in stimulation , so this study is interesting to evolution the effects of splashing by different levels of Gebberellin acid for green groups of safflower which are growing in pollutant soil by Zinc in growth, tolerance, crop, chemical structure , and the production of protein and carbohydrates.
