EFFECTS OF ORGANIC SOLUTIONS ON GROWTH AND PHYSIOLOGICAL PARAMETERS OF TRITICUM TURGIDUM L. VAR. DURUM
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 3
Abstract
Recently, dust particles have raised concerns. It seems dust particles have nutritional values and can improve plant nutrition. It is proved that atmospheric dust particles could enhance the production of Fe2+ in the presence of atmospheric water. In this study, these properties of the desert soil were tested on the wheat (Triticum turgidum L.) using Hoagland nutrient solution, illuminated soil solutions from Saharan desert, Tanzania, Tehran and Zabol city by simulating atmospheric conditions for dust particles. Therefore wheat plant seedlings were treated by illuminated soil solutions from Tehran, Sahara, Tanzania and Zabol under laboratory conditions of 14/10 day/night and 25 oC. Control plants and plants that treated with Hoagland solution were grown in similar conditions. Results showed that fresh and dry weight of plant parts that treated with illuminated soil solutions enhanced, and it is because of nutritional properties of these solutions, but results of enzymatic and non-enzymatic antioxidants shows its stressful properties. Besides, results of iron concentration evaluation in treated plant shows that these solutions can enhance iron absorption. So soil solutions have stressful properties and nutritional values. It is necessary to investigate health aspects of dust particles, besides their relation to economic importance in organic farming development.
