Abstract
This study included testing the efficacy of the aquatic and alcoholic extracts for rhizomes of turmeric (Curcuma longa L.) and roots of eggplant (Solanum melongena L.) in the germination of local wheat seeds stored in the main storeroom and storerooms of Mabain AL-Nahrain company for seeds production in Al-Diwaniya city for culture season 2006-2007, and study the effect of four concentration of these extracts it are (5, 10, 15, 20) mg/ml in radial growth and spores germination for some fungi isolated from wheat seeds, and testing the effect of dried powder and alcoholic extracts for tested plant in germination of wheat seeds stored in the Mabain AL-Nahrain company in sterilized and unsterilized soils. The results showed that there are significant differences in the percentage of wheat seeds germination in different concentration for extracts in measuring with controlled treatment, and there are no significant differences in the percentage of wheat seeds germination at concentration 20 mg/ml for different treatments in measuring with treatment of fungi disinfectant (Dividend) at level of possibility 5 %. The all extracts were had significant inhibited effect for growth of tested fungi on solid culture medium (Potato Dextrose Agar) in measuring with controlled treatment and this fungi are: Aspergillus niger, Alternaria alternata, Penicillium notatum and Fusarium oxysporum, and alcoholic turmeric extract was the most effective extract on tested fungi, and this extracts were reduced from the percentage of spores germination for tested fungi in significant form in measuring with controlled treatments at level of possibility 5 %. The results showed that there are no significant differences in the percentage of wheat seeds germination at concentration 15, 20 mg/ml for dried powder treatments for turmeric and eggplant plant in measuring with alcoholic extract treatments for turmeric and eggplant plant in sterilized and unsterilized soils at level of possibility 5 %.
